It's just an educated guess on my part since OP mentioned he is on Sierra, so I'm guessing he is using apps that were prior to Sierra or bought on Sierra. But for lots of games and utilities, developers have not released 64-bit updates, and never will.Īgain this depends on what OP uses. The big ones, like Microsoft Office and Adobe Photoshop, sure. If money no object then Catalina, cos you can repurchase all the apps over again for compatibility. I don't know what apps OP is using, might or might not have a fix for APFS.
Many of the issues were with the new file system that Apple introduced, since the launch these issues particular are likely to have been fixed.
I found something that mentioned some apps and at the bottom there's a short para: Only OP can verify what apps he is using that is (not) affected by APFS. Hi.S can still be installed with HFS+, it has an option to run on HFS+ during install. How do you figure that? All three will convert internal SSDs to APFS during installation – but they still have no problem working with external HFS+ drives. If you have stuffs that still need HFS+ to run, then the only choice is Hi.S
