Apple could have chosen to make APFS open source or to document it fully, to help third parties develop maintenance tools. It chose not to, but Disk Utility still doesn’t work as it should.
APFS
APFS backup disks offer different possibilities for adding volumes for your own use, alongside the backup volume. How do you decide what’s best?
It depends whether you’re going to boot macOS from it, on the space required for snapshots, and how large they could become. And there’s more.
File data stored towards the periphery of the disk is read and written nearly twice as fast as that near the centre. How to take advantage of this.
Which is faster with a hard disk: using APFS or sticking with HFS+? Are there any differences in their performance on SSDs?
Provided in Archive Utility and three command tools, its LZFSE compression even supports APFS special files like clones and sparse files.
Internal or external? Hard disk or SSD? USB or Thunderbolt? Cooled or compact? Branded or separates? An external boot disk? Do you have a return and refund option?
What’s the Update volume doing weeks after the last macOS update? What can I do if ejecting my Time Machine backup storage causes an improper ejection error?
We’ve recently discovered a macOS service for ‘trials’ which runs ‘experiments’. Why hasn’t Apple told us, and explained its implications for our privacy?
Born secretly on 27 March 2017, it was Apple’s biggest gamble. Introduced in High Sierra, it didn’t work on Fusion Drives and had other problems. Also explains version numbering.
