Seems like Apple is no longer intent on keeping third-party MacOS backup solutions in business much longer. Everyone *must* use Apple's Time Machine, no exceptions.
Good luck also with recovery of said data if you don't have a backup.
Yikes... I knew this was coming. The move away from general-purpose CPUs means a gradual lock-down of the Mac. I'm starting to wonder if Apple really did plan to make the Mac App Store be the only place you could download software for your Mac... Jeez...
I'm thanking my lucky stars to have recently purchased one of the last Intel-based Macs, where at least I'll be able to modify bits and pieces as desired. Super prudent to not have bought into an Apple Silicon-based Mac!!!
Once again, Apple is making me question whether I want to continue giving them my business for, what has been for multiple years of providing a superior, highly stable, and commercially supported OS. If only Canoncial's Ubuntu would have just a bit more *native* support (meaning, no WINE) from companies like Microsoft and Adobe, then I'd be happy to escape from MacOS.
