[QUOTE="chscag, post: 1836731, member: 46727"] Welcome to our forums. Apple has been warning users for the past two years that 32 bit apps would no longer be compatible. At the time they first issued the warning it was going to be for Mojave but they relented and decided it would be Catalina instead. As for APFS, (new Apple file system) it should have no impact on the apps you run or the structure of your hard drives. If you reverted to Mojave, you still maintained the APFS file format regardless of running a SSD or spinner drive. There is a work around for keeping the HFS+ file system with Mojave but it's not something I would recommend. Glad to hear that you were wise enough to know that backups are invaluable. Carbon Copy Cloner has saved me from disaster numerous times. I too am sticking with Mojave as I have an app that is 32 bit that I can not do without. However, I keep up with Catalina by booting it from an external SSD. (Samsung T5) [/QUOTE]
