Most Recent Office You Can Run – Best Practices

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.

Office for Mac Update History

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.

  1. Curious what are your thoughts on the upcoming Office 365 with copilot (Ai) for all MS Office suite. How will that affect customized corporate templates in Word and PPT. I guess we will need to wait anyway.

    • Microsoft as much a marketing company as it is a technology firm. At the moment they’re capitalizing on the current hype about A.I. We’ll see what the reality is, down the road.

      Most of the hypothetical uses I’ve seen from them are about using templates rather than creating them. The Design Ideas feature in Microsoft 365 is already run by A.I. and it’s horrible from a template design perspective. Shapes are locked, many designs are applied to slides instead of layouts, and it’s not configurable or searchable.
