The APFS feature that I'm having the most trouble with is 'purgeable' space. It's extremely not clear when it purges or if it matters whether it's a user-visible application or a unix-y utility like cp consuming space. I seem to be able to run out of disk space and have problems when 100s of GBs are supposedly purgeable. There are CLI commands to purge space, but it's also unclear from the man pages what the parameters are supposed to be to get it to do the thing.
- mouth 3y agoI have found that a reboot has freed up purgeable space when the CLI commands fail to do so. Very frustrating to need to reboot solely because your filesystem seems to be holding disk space hostage.
- steve1977 3y agoTo add insult to injury, some Apple apps don't seem to handle lack of disk space very well. I recently couldn't get Photos to import photos from my iPhone anymore. I didn't get any error message or anything. I would click on Import, it would (seemingly) start and then just stop the import without anything actually imported. Then I noticed that I was very short on disk space, so I deleted some stuff. Which of course didn't immediately free up the space due to TM snapshots. I didn't want to mess with Time Machine, so I just waited 24 hours, and lo and behold, there was more free space and import in Photos was working again. This is with an older macOS version, so maybe this has been fixed in the meantime. But it's not really what I would expect from "it just works".
