Gregory's ServerTempting. Catalina is one of last good ones, right?

 @nikitonsky nope, it was actually one of the most user-hostile upgrades: switch to 64-bit only, added Catalyst crap, and broke AppleScript for a bunch of native apps (eg Notes). You’d need to go pre-macOS, pre-flat-icon for a decent operating system for the Mac.  @nikitonsky I guess Chrome and Firefox are still updated on that version, if you plan to use it for browsing… |
Catalina is the one that dropped 32-bit apps, so Mojave is the last good one. Mavericks is the best one tho.
