No.
Can't run current versions of any apps including Chrome, Edge, and Safari.
Meanwhile the hardware is perfectly fine and could run a supported version of Windows or Linux.
Call me when Apple has a "LTSC" version of their OS. (Spoiler: they won't, ever. Supporting Apple in an enterprise is nothing short of a nightmare.)
This is partially on third-party devs' shoulders. There are community-maintained backports of Chromium and Mozilla for old versions of macOS, which means it isn't strictly impossible, but Google and Mozilla just don't bother and cut off compatibility earlier there than on other platforms.
It's even possible to build Mac apps to run on everything from OS X 10.4 (2005) through macOS 27 (2026) across PowerPC, Intel, and Apple Silicon in a single binary. See XLD[0], which does exactly that.

I have had to get rid of several computers recently that will not run Windows 11. They weren’t 12 years old.
