Are there different versions of APFS between Sierra, High Sierra and Mojave?
I am opening PDFs in Acrobat Professional and while the speed of opening in Sierra an High Sierra is the same, in Mojave it is consistently about 5 seconds slower.
Any ideas?
It would not be because of the format. I have some apps that open faster in Big Sur than they did in Mojave so could just be the OS differences.
For the record - APFS was introduce After Sierra was made Public and Sierra never was supported on the new Apple Filing System. High Sierra was supported on APFS but only if the Internal Drive was an Apple Original SSD and Not on Rotational Drives. Same goes for Mojave.
Yes there are different versions. If you attempt to run First Aid from an older OS on a volume created by a later version of macOS, then First Aid will alert you to the fact and not repair the volume since the APFS volume created by the newer version of macOS contains features that the older OS may not recognize or know how to deal with.
