How can I update Microsoft Word while on macOS High Sierra?

I'm trundling along on a Mac OD High Sierra, which is brilliant, but now find I cannot update my Microsoft 365 Word account for auto save etc. Is there a way round this? It also won't support Google Chrome, only Firefox. I'm being backed into a corner by BIG TECH. I don't need any higher spec desktop, and could only fork out for a new model if this expires altogether. Help me out please.

High Sierra is obsolete and incapable of taking advantage of features of the modern internet and the newest software. It has not seen a point update in about seven years. HS is seven major OS revisions behind the current Sequoia.


Microsoft now supports only the three most recent releases of macOS with their software. Those are macOS 13 Ventura, 14 Sonoma and 15 Sequoia.


The only update/upgrade path for MS apps that run in High Sierra is to purchase a newer Mac that can run the newer macOS and then to also subscribe to or buy the newer MS software. There's no workaround if you wish to continue to use the MS apps.

Thanks for that. I suspected as much. This is hi-tech's built-in obscolescence. They could make things work for me, but that wouldn't sell their new equipment....the rhetoricaL question is, if I had all the latest equipment, how would that improve my output? Why do we need constant upgrades. Our TV streaming Apple TV was bought specially for the Olympics-before-the-Olympics-before the Olympics. The pictures fabulous. 90% of the shows are dross, and would not be improved whatever state of the art screen we had. There is something broken in a world where everybody has to have what's new. Anyroadup, as they might still say in my native Yorkshire, thankyou for taking the time to reply. The human touch really is irreplacable.

You cannot update Microsoft Word while running High Sierra.


Microsoft has a policy of only supporting the three most recent versions of macOS. Those are currently Ventura, Sonoma, and Sequoia. High Sierra is seven major versions behind Sequoia, and fell out of the "most recent three" more than four years ago, in November 2020, when Big Sur came out.

"What if I don't update macOS to a supported version?


If you're on an unsupported version of macOS, your Office apps will still work but you would no longer receive any updates including security updates"


You cannot even run the current version of LibreOffice on High Sierra. At least with LibreOfice, you can still get an old, unsupported version that is compatible with High Sierra from the archives (if you can identify which of the old versions to download).

I use LibreOffice in all my Macs down to El Capitan and High Sierra. At work I used LibreOffice and the latest MS Office side by side for the same documents without any ill effects. Take the following page with a grain of salt because while I use the latest LibreOffice 25.2.2 in Ventura but some user had to download the previous version to make it work in his Ventura (make sure to download the Intel version).
