Which is faster with a hard disk: using APFS or sticking with HFS+? Are there any differences in their performance on SSDs?
APFS
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.
All disks cache data to be written, which makes benchmarking them tricky. It has more serious consequences which macOS tries to allow for in file systems and backups.
Why Time Machine makes snapshots, and how they can grow and apparently consume free space. What you can and should do to manage this.
One likely cause of vanishing free space are large snapshots. So how can you tell why a snapshot is large, and how can you avoid it?
Problems with the file system of Time Machine backups haven’t gone away with APFS. As there’s no way to copy your backup volume, how to tackle such problems?
