As Apple and Microsoft release new operating systems, it’s no longer possible to install the latest version of Office on your old computer. Here’s is a list of the most recent Office you can run for the operating system you have, plus where to find it.
Most Recent Office You Can Run on macOS
Rant alert! Microsoft supports the last three operating systems in both Windows and Mac. Unfortunately, Apple has a policy of releasing a new operating system every year, whether we need it or not. The result of these two business decisions is that there are rafts of perfectly serviceable Macs out there that can no longer install the current version of Office. It looks like Apple intends us to toss them and buy new ones. Another case of lip service to environmental sustainability. Rant over
If you buy or subscribe to Office for Mac today, you’ll only find the current versions of Microsoft 365 (the subscription version) and Office 2021 (the retail edition) to be easily available. But Microsoft maintains a page of older installers at Update history for Office for Mac. All of them can be activated under a current Microsoft 365 subscription or Office 2021 license.
Please note that all of these are final releases: there will be no security updates to follow. Be careful when downloading Office files from the interweb.
At the time of writing, the current crop of obsolete Macs are those that can only run Catalina. These are machines that are around 10 years old, but are completely useable for applications like Office. The last Office version that Catalina can run is 16.66. At the History page, look for the Installer dated October 11, 2022. Download and run the installer. Then, in an Office program, choose Help>Check for Updates to get the final 16.66.1 version.
Catalina was the first OS to require 64-bit software. This requirement made Office 2011 obsolete, since it’s 32-bit. But Office 2011 is still a useful edition in macOS. It can still do things that were permanently removed from later versions of Office. So you might want to stick with Mojave and install the newer Office that goes with it. (There’s no problem in having Office 2011 and a later version installed on the same computer.) In this scenario, download and install the 16.54 version dated October 12, 2021.
One of my favorite Macs is my 17″ MacBook Pro. It’s the machine that travels with me, but it’s 12 years old and can run only High Sierra. The most recent Office you can run on this computer is 16.43, dated November 10, 2020.
There’s a pattern here: Apple releases new operating systems in the fall, usually in September or October. The Office version that Microsoft releases the same month is the last one for the fourth-oldest macOS. I don’t have any machines running Sierra, but if I did, I would try the October 15, 2019 edition of Office 16.30.
As I mentioned earlier, you can run an older version of Office on an older computer. Since Office 2008, the file format has remained pretty constant, so the software can still be useful. You can install Office 2011 under Mojave or earlier, while Office 2008 can be installed under El Capitan and earlier. These versions can co-exist on a Mac with a newer version (or with each other), though Microsoft’s History page only goes back to 16.27 from July, 2019.
Most Recent Office You Can Run on Windows
Under Windows, the situation is easier, as Microsoft waits about 3 years between operating systems. Plus Windows isn’t as finicky about the hardware it runs on. I have an old Mac Pro from 2006 that can only run OS X Lion and Office 2011, but under Boot Camp it does either Windows Vista and Office 2010, or Windows 7 and Office 2016. Windows 8 is likewise limited to Office 2016, while Windows 10 (now 9 years old!) can run the current version of Office 2021 and Microsoft 365. You have to have a really old Windows computer to be unable to run a useable copy of Office.

The vast majority of presentations are created using the default templates that comes with Microsoft PowerPoint. All Microsoft-compatible PowerPoint templates have a uniform structure, and the result is that you can copy and paste slides between any deck and the paste works as expected: the content comes across perfectly, and the formatting is updated.
But in almost all corporate presentations with custom templates, this no longer works. Slides pasted from Microsoft-based presentations always need to be reformatted manually, because the custom template haven’t been created to be Microsoft-compatible.
It doesn’t have to be this way. Here’s how to create custom templates that will be both Microsoft-compatible and have a look and feel that is brand-compatible with the organization.
What’s in a Microsoft-Compatible PowerPoint Template?
Most designers create presentation templates incorrectly for the purpose of importing of slides created with Microsoft templates. Almost universal infractions include deleting or renaming the default slide layouts, and deleting or adding placeholders on whatever default slide layouts are left. Less common methods that designers use to wreck templates include deleting all placeholders on the master slide, and deleting all default layouts, then trying to replace them
To understand why these actions could cause problems, we need to understand the PowerPoint file structure. All new blank PowerPoint files contain the following:
1 Master Slide (in Slide Master view, the larger slide at the very top of the left-hand thumbnail list). The parent to all the layouts, to which the slide layouts are children. All text formatting is inherited from this slide. Deleting placeholders here will cripple the template.
11 default slide layouts, which inherit the formatting set in the master slide. These 11 comprise:
Title Slide, for the presentation title.
Title and Content, for the bulk of the presentation content.
Section Header, to divide the deck into relevant sections.
Two Content, with 2 content areas.
Comparison, similar to Two Content, but each content area also has a corresponding heading placeholder.
Title Only, displaying only a Title field, with the rest of the slide blank.
Blank, with not even a Title field.
Content with Caption, a little-used layout the includes a Title, Text and Content placeholder.
Picture with Caption, similar to Content with Caption, but with a Picture placeholder replacing the Content one.
Title and Vertical Text This layout is intended for Asian language use and is only displayed as a choice if your operating system has an Asian language set up.
Vertical Title and Text Similar to the previous layout, only visible on computers with Asian language input enabled in the operating system.
Each of these layouts has a specific layout type, set in XML and not alterable in the program interface. You can create the correct placeholder types by generating a new, blank PowerPoint file. Each of these layouts contains placeholders for the date and slide number, plus a footer field. All but 1 have a title placeholder.
Here’s the second line of a default Microsoft layout. In this example, obj is the XML type for a Title and Content layout:
PowerPoint reads the userDrawn property and will not treat your layout as a default layout no matter what you do to it. It will never be Microsoft-compatible.
If you have deleted a default slide layout, you can restore it by creating a new blank presentation, then copying and pasting the layout under the slide master of the deck to be repaired. You can also restore a default layout by running this VBA:
.Add(.Count + 1, ppLayoutObject).Delete
The example above restores a deleted Title and Content layout. Just change ppLayoutObject to the type you need from this list:
Title and Content
Content with Caption
Picture with Caption
Title and Vertical Text
Vertical Title and Text
Here are the recommendations that Microsoft should have published with the release of PowerPoint 2007: All new PowerPoint templates should include all default slide layouts and placeholders. That would have saved so much grief! Every file would be a Microsoft-compatible PowerPoint template or theme.
Please note, I am not suggesting that you restrict your design to only these layouts and placeholders. As long as you have the default layouts with the default placeholders, the rest of the master slide view can be filled with all kinds of special-purpose layouts with any number of placeholders. Just remember, whatever you create today must be supported in the future, if the slides are to remain paste-compatible. For more details, please see my article about best practices for reusing old (legacy) slides: Legacy Slides – Best Practices
I’m adding a plea for sanity on behalf of users everwhere: restraint in slide layout numbers is best for your client’s users. Too many layouts and they just don’t know which one to pick! Don’t confuse them more than they already are. Consider a limit of 25 layouts maximum.

Unlike PowerPoint, Microsoft Word has a utlity to create custom Word table styles. You might think this makes life a lot easier, but you would be wrong. The Word utility has quirks and bugs, and Word tables don’t work the same way as PowerPoint’s. To get a Word table style to work closer to the way it should, you may have to hack the OOXML. Here’s how to get the best possible results.
Start with a similar table style
The first step in creating a custom table style is to insert a table, so the Table Design tab appears. By default, a new table will use the Table Grid style, which is very plain. If your final table style requires design options like a distinctive first column or a total Row, Table Grid is a poor place to start. It doesn’t include any of those options, and adding them back in is difficult. Switch the style to a Microsoft default that already has similar features. Next, expand the table style gallery dropdown again and select New Table Style at the bottom. This ensures that your table style will appear in a new Custom row right at the top of the styles gallery. By contrast, starting with Modify Table Style lumps your style in with all the Microsoft defaults.
Base the new style on the chosen one
When you choose Table Design>Table Styles>New Table Style, Word sets the Style based on dropdown to Table Normal, not the style you chose. If you originally chose Grid Table 5 Dark, then set Style based on to the same style name. (Current versions of Word for Mac have a display bug whereby choosing a different table style does not update the preview in the dialog. Choose the style, OK out, then choose Modify Table Style to see a corrected preview.)
Word Table Style Quirks
There are some oddities about Word table styles, and a few bugs. One oddity is that table text is based on the Normal style in relationship to Word’s Default Text settings. If Normal has been set to any color other than Automatic, applying different text colors to different table parts will have no effect. The text will remain the color set for Normal. You then have to apply new paragrpah styles to the table parts after creating the table.
Another weird result of the dependency on Normal is that Word expects to have the default line spacing for your version of Word. As I write, Word 365’s default Normal style has a Line spacing of Multiple at 1.08 with Space After of 8 points. In a table style, this gets automatically reinterpreted as Single with 0 before and after. Centered vertical spacing then works as expected. If you change the Normal line spacing to a larger or smaller value, text that is nominally vertically centered will actually sit higher or lower in the cell. If you add 12pt after, the table text will jump from being vertically centered to having 12 pt after, a huge difference. Microsoft doesn’t publish any of this information. Surprise!
This is one of the reasons why Word experts recommend that Normal style should stay as is and not be actually used in a document unless the default formatting matches the needs of the design. Better to format all text as Body Text style and give that style the custom color and line spacing.
But what if you’re given a template that already has a non-standard Normal, and the client asks for a table style? All is not lost. Table styles can still work as designed if you are using Word for Windows (sorry, Mac people). The trick here is to set the document text defaults to the same values as the revised Normal style. (Thanks to MVP Stefan Blom for this tip.) Here’s how to do this:
With the document or template open in Word, click on the Styles pane dialog opener below the Quick Styles gallery, or press Alt + Ctrl + Shift + s at the same time. The Style pane opens.
Click on the Manage Style button at the bottom.
Select the Set Defaults tab.
Set the defaults to the same values as Normal style: same font, size, color and paragraph settings. OK out.
You’ll know you got it right when you insert a table in the new style and it automatically has the correct styling for header row, first column and the other table style options. It is no longer necessary to apply text styles to the table, you can simply turn the Table Design>Table Style Options on and off to affect the related table area.
Word Table Style Bugs
Lousy User Interface Design
In the table style dialog, color dropdowns remain set at the color last chosen, even if that was for a different table part. The dropdown should update to the color currently in use for the table part that has been selected. This is just common-sense UI design.
The interface for setting border styles is pretty bad. It’s almost impossible to set one color for vertical borders and a different one for horizontal borders. All borders switch to the last selected color. But we can fix this with an OOXML hack (see below).
Defective Override Capabilities
Subsequent parts can’t always override the XML of earlier parts. As an example, set the Whole table to have internal vertical rules. Then set the first column to have no rule on the right. This should make the vertical rule separating the first column from the second column disappear, but it doesn’t. The rule has to be manually removed after the table is created.
Non-Functional OOXML Tags
The Paragraph Properties (w:pPr) element for each table part has a pStyle attribute that is supposed to set the paragraph style for that part. It does nothing. As mentioned above, the style is always derived from Normal style.
Format the Word table style options in order.
Start by formatting the Whole table section with the defaults for cell in the middle of the preview. Most of the time, this will include the font size and color, and the table background color and any rules that are to appear if banded rows are turned off. If you can’t get the formatting you need from the few controls on the dialog, click on the Format dropdown to find detailed access to Table Properties, Borders and Shading, Banding, Font and Paragraph attributes. Under Windows, you’ll also see a Text Effects choice, which is of dubious value in a table.
Then move on to Header Row formatting, the next item on the Apply formatting to dropdown. Format each item on that dropdown until you have set all the properties you need. After you get all formatting set, apply the custom style to the sample table you created at the beginning. Then use Modify Table Style for any tweaks required.
Word Table Style Hacks
Default style formatting is hardcoded in Word. So the styles that get stored in a Word file are only styles that have been modified or newly created in the document. All of the style exceptions and new style definitions are stored in the word/styles.xml part. Here’s the OOXML for a full table style. First, the section that formats the whole table. Pr stands for Property. tbl is Table, tc is Table Cell, p is Paragraph and r is Run (any length of text less that a paragraph).
(Above) The w:rPr section sets the default text while w:tblPr sets the borders. This table is transparent when all design options are turned off, so there is no fill. Note the entries for w:insideH and w:insideV. I had to hack this XML to get different colors for the inside horizontal and inside vertical borders.
(Below) Next is the formatting for the header row. w:rPr sets the text as bold and white, while w:tcPr sets the cell borders to nothing and the fill to Accent 2.
(Above) The previous section formats the Total Row, removing the borders. There’s another hack here: the w:shd illustrates how to set the fill as No Color, with both w:color and w:fill set to auto.
(Below) Next up is the First Column formatting. w:pPr sets the text flush right, w:rPr makes it bold and w:tcPr removes the borders and keeps the fill No Color. Oddly, while w:insideH successfully overrides the internal horizontal rules set in the Whole Table section, neither w:right nor w:insideV are able to remove the internal vertical rule to the right of the column. This works as expected in a PowerPoint table style, but is broken in Word.
(Above) The right-most table column is formatted with no borders and no fill.
(Below) If your design includes banded columns, the table style will include a section like this. There is just a definition for odd columns: even columns would be formatted with the defaults from the Whole Table section. If the First Column option is turned off, odd columns start at the left-most column. If First Column is turned on, all columns shift and the column just to the right of the first column takes on odd column formatting.
(Below) Formatting for the 4 corner cells. These are only activated when both options that affect the cell are turned on. As an example, if the table has both a Header Row and a First Column, then the nwCell formatting is turned on. In the formatting for nwCell below, the text becomes flush right when both options are used.
If you base your Word table styles on a table other than Table Normal, that table style will be included in styles.xml. If that table style includes formatting that you don’t want to included in your table style, then delete the section in the style it’s based on. As an example, this style was based on Grid Table 3, which includes a last column and a total row. To remove all last column and total row formatting from your style, delete the corresponding XML sections in both your custom style and in the style on which it’s based. You’ll know when you’re succesful when turning the Last Column and Total Row Design Options on and off in Word has no visual effect on a sample table.

I don’t actually know much, but I have search engine expertise. I’ve answered thousands of question for users on various online fora, and I’m constantly amazed by the vast number of queries that could be answered by a simple Google search. My takeaway is that people just don’t know how to use search engines to their best advantage.
Search Engine Expertise – The Mandatory Word
When a search must include a particular word or phrase, put it in double quotes, if you’re using Google. For Bing and most other engines, add a plus sign before. Here’s a search that must include Word in the results:
Google - "Word" VBA typestyle
Bing and others - +Word VBA typestyle
Search Engine Expertise – The Excluded Word
You’re looking for Word VBA information, but you get pages of useless Excel stuff. For all search engines, add a minus sign before the word you don’t want:
VBA -Excel tables
Search Engine Expertise – The Special Site
You know that you saw an answer on a particular web site, but it was a long time ago and you can’t remember where. Type your search terms, then type site:, then the site URL. No space between site: and the URL:
"edit mode of header/footer" site:answers.microsoft.com
Searching Phrases Instead of Words
Put the phrase between double quotes. The following shows results about the top of the page that don’t refer to the header and footer:
Word top part of page -"header and footer"
A Practical Example
Do you use Office for Mac? It’s hard to find relevant information, since the Mac version is still quite different from Office for Windows. Just add “for Mac” to your search terms and watch as hundreds of pages of useless Windows pages disappear. This can save you hours of time!
Using just these 4 tips, you’ll find relevant information much more quickly. You may have even more specific requirements. Check out the Advanced Search page for your preferred engine, you may find some techniques that will make your day more efficient:
One of my areas of expertise is to do presentation assessments for designers, finding any potential problems in their work before sending their file to their client. Something I see fairly often is multiple slide masters in a template or theme, where they are used as an organizational tool. Typically, one master will be for title slides, another for section headers, and so on. This is a poor practice, but it goes on because designers never have to actually use the files they create. If they did, the problem would soon become evident. Here’s a typical example:
Multiple Slide Masters – How They Work
If I asked you “How does PowerPoint know which slide master to use when there is more than one?”, what would your answer be?
Well, I’ve done the research, so I can let you know. When you paste slides into a presentation, PowerPoint looks at the slide immediately preceding the paste position and uses the slide master for that slide. If there are no slides in the presentation, then PowerPoint uses the first slide master. This has major consequences for the format of the pasted slides. If the slide master of the preceding slide has only title layouts, only the pasted title slides will find their rightful layout. All the rest of the slides will bring their old layout with them. So now the slide master for titles has a whole bunch of non-title layouts. Oops. So much for your organizational scheme. Following are the original slides, followed by what they look like when pasted after slides based on different masters:
If the pasted slides are from legacy presentations, where the intention was to update them to the new look, you get a total fail. Not only do they not update, they’ve ruined the new deck with added old layouts. The next time the user adds a new slide and tries to find a layout in that slide master, they get a psychedelic soup of designs.
But wait! It gets worse! For some bizarre reason, designers have a bad habit of deleting all the placeholders on the slide master, then building the design in the layouts. Ouch! The placeholders on the slide master are parents to the child placeholders on the layouts. They are the source for font and paragraph formatting in layout placeholders, as well as the default placeholder positioning. When you paste slides so they use that blank slide master, formatting goes haywire. The slide layouts that get imported with the pasted slide have no source to tell them how to display content. PowerPoint makes a guess and always guesses wrong. Bold text becomes regular, font sizes changes, pictures disappear. It’s a nightmare, and one that designers just don’t understand, can’t explain to their clients, and have no idea how to fix.
A Better Approach
Just use a single slide master. In 99% of presentations, one slide master is all you need. That slide master should be formatted as closely as possible to look like a typical content slide. Then for layouts that have different formatting, right-click on the layout background and choose Format background. In the Format Background task pane, check the option for Hide background graphics. Then place the alternate graphics on that layout.
About the placeholders: keep them! Deleting the default placeholders does nothing helpful and can cause problems. If someone pastes a slide with a footer and your layout doesn’t have a footer placeholder, the footer text will reposition itself, often at the very left edge of the slide, because the content has been orphaned. If your design doesn’t include a footer, move the placeholder off the bottom of the layout! This makes a pasted footer simply disappear instead of looking goofy.
Multiple Slide Masters – When and How to Use Them
So far, there are only 2 uses I’ve found a genuine need for multiple slide masters. One is when a presentation requires multiple color themes. Some organizations have divisions that use code colors: a key color that is used only in that group. This situation was easier in PowerPoint 2003 and earlier, because you could easily apply different color schemes to groups of slides. Modern versions have only 1 color theme per slide master. If you change the color theme, all the slides change. Here’s how to handle that situation:
Under the slide master, create the complete set of layouts needed for the presentation. Set the code color in Accent 1 if it’s a predominant element of the client branding. If it’s a subtle design change, Accent 6 is better. Get the client to sign off, so the design is not going to need a lot of future revisions. Then copy and paste the slide master for each code color required. Finally, revise the color theme for each slide master, changing only the accent color. Following this method, every slide master has every layout. The worst that can happen is someone pastes in the wrong place and the code color is off. Easily fixed.
The other time you need multiple masters when a client has rolled out a new template, then realizes they need to handle legacy slides. Then you create a second slide master with layouts that match the new look but have a layout structure that is compatible with the old decks. At the beginning of the deck create 2 sample slides, one based on the new slide master and another based on the legacy slide master. Place a notice to the user just off the edge of the slide master for the first slide: “New slides only! Don’t paste old slides!” and on the second “Paste old slides here! No new ones!”. Then users are less likely to paste slides in the wrong spot and get weird results.
The Best Practice is to NOT use Text Effects in Office. Ever.
That could have been my shortest article ever, but I guess I should explain the reasons. I’m referring to the graduated fills and lines, the glows, reflections, shadows and 3-D effects you can add to text. In the past these effects have caused some problems with ordinary shapes, but with text, they’re a disaster.
Clearly, it’s not enough for most users that these effects are visually hideous. That just a natural result of the low value we assign to arts education. In many years of working with competent graphic artists, I’ve never been asked to create any template that uses these effects. Designers understand the need for restraint, users don’t. And so we get the appalling appearance of most Word and PowerPoint documents.
But the functional problem with these effects is how they affect PDFs created from Word, PowerPoint and Excel. Microsoft has no clue how to export true PostScript of the fancy effects. So they adopt a simplistic approach: flatten them to graphics. Unfortunately, this means the text vanishes, leaving behind only a pretty picture. Well, not even that. All kinds of PDF functions are impaired: Text to speech is impossible, accessibility goes right out the window, reimporting the PDF to Office is brain-dead.
I tested PDFs created in 3 ways: saving to PDF in Office, printing to Acrobat and printing to the Microsoft Print to PDF print driver that comes with Windows 10. When saving to PDF, all text with applied effects was flattened. When printing to either Acrobat or Microsoft Print to PDF, Gradient Fills, Gradient Lines and 3D Effects were flattened, while Shadows, Reflections and Glows remained as live text.
The moral is clear: when the client asks for Text Effects, just say NO!
Back at the dawn of time, when PowerPoint was first being programmed, a fateful and incorrect decision was made. Placeholder content would always appear in front of static content, regardless of how placeholders and other content were stacked on the layout. This has led to countless bald designers, from them tearing out their hair because there’s no way to place logos over photos.
The Locked Graphics Workaround
One way to circumvent this design flaw is to place a picture placeholder on the layout as usual. Then create a sample slide from it. Place the logo over the photo and lock its position in the XML. Here’s my article on how to do that: OOXML Hacking: Locking Graphics. This allows the user to replace the photo while keeping the logo in front.
The disadvantage is that you can’t create a new slide from the layout. Instead, the user must copy and paste the sample slide to create another one.
The Background Picture Fill Workaround
If the photo is a full-screen photo, there’s another method. This time, don’t place a picture placeholder on the layout. Instead, just place the logo there. In use, the user right-clicks on the background and chooses Format Background. On the Format Background task pane, choose Picture or texture fill, then click on the File button and choose the background photo. The logo will stay on top.
The disadvantage to this technique is you have to include instructions to the end user, who may never have used a picture fill previously. My thanks to Jaakko Tuomivaara of Supergroup Studios in the UK for this tip.
The Holey Placeholder Workaround
For simple logos, or logos contained in a simple shape like a circle or square, create a logo-shaped hole in the placeholder. Here’s a Windows-only version.
On the layout, create the picture placeholder.
Insert the logo as an EMF vector file, then ungroup it twice, confirming with PowerPoint that you want to do this. This changes it from a placed picture to a set of vectors embedded on the layout.
With the logo parts selected, hold the Shift key and click on the placeholder.
Fill the background, or a shape placed behind the logo hole, with the logo color.
If the logo is in a shape, you can use similar steps on both Windows and macOS computers. Using Mac command names: Place the logo over the placeholder, then draw a Shape exactly the same size as the logo, placed over the logo precisely. Select the shape and the placeholder, then use Shape Format>Merge Shapes>Fragment, then delete the shape to reveal the logo-sized hole in the placeholder. For some reason, Merge Shapes>Subtract works differently on a Mac, deleting both the shape and the placeholder, but Fragment still get the job done. Thanks to Ute Simon for suggesting this method in the comments.
A variation on this that can be more detailed is to place a copy of the logo above the placeholder. Then, shape-by-shape, use the logo over the placeholder with the Combine variant of Merge Shapes to knock holes in the placeholder. Then add colored shapes below the placeholder to “fill” the holes. If you have compound shapes (like the letter O or A), you’ll have to release the compound shapes, then connect the inner shape with the outer one. Here’s what the end result looks like in Illustrator.
Logos Over Photos: The Placeholder Picture Fill Workaround
This works with any size photo, it doesn’t have to be full-frame like the previous hack. No copy and paste, no instructions required. I heard about this one from Joshua Finto (Make It So Studio in Austin, TX).
On the layout, insert a picture placeholder to hold the photo. Then add another placeholder on top, sized to exactly the same size as the logo. I use Online Image placeholders because they are rarely used, using a common placeholder type risks content being placed in it if you change layout types. Remove bullets, if there are any, and type a space character so no placeholder text appears.
In the Format Picture task pane, click on Picture or texture fill, then on the File button and fill the placeholder with the logo. Create a slide, place a photo and voila! The logo appears over top of the photo! After creating this, it’s wise to lock the placeholder in XML on that layout, to prevent distortion by the user playing with it. OOXML Hacking: Locking Graphics. EMF, SVG and transparent PNGs are all good logo formats for this application.
Microsoft maintains Feedback forums to collect feedback from users. I’ve created a suggestion there that the placeholder/shape stacking order on the layout should be respected on slides. Please add your vote here: Placeholders Should Not Pop to the Front. Perhaps we can persuade Microsoft to fix the mistake so we don’t need these time-wasting workarounds.
Thanks to my readers who have added some useful suggestions! Please read the comments for additional ideas and tips.
