MaintenanceTool not enough free space OSX
-
MaintenanceTool is telling me that I don't have enough free space to do an install when OSX clearly has double what it's asking for. How can I fix this short of deleting stuff or doing a complete reinstall?

Hi,
How much free space do you have ?

Okay, so here's what's going on. If you use Time Machine, backups happen to the local internal storage even though you may be using a NFS storage device. These can be very large. OSX considers this space to be purgeable and it will appear in Finder windows that you have a lot of free space. However, when you look at the drive in Disk Utility, you won't see all of that free space. Time Machine eventually frees up this space for regular use. You can accelerate this process by using tmutil in Terminal. For example:
tmutil listlocalsnapshots /
Snapshots for disk /:
com.apple.TimeMachine.2023-05-05-125631.local
com.apple.TimeMachine.2023-05-05-135413.local
com.apple.TimeMachine.2023-05-05-145603.local
com.apple.TimeMachine.2023-05-05-160247.localShows the backups but it doesn't show their size. tmutil thinlocalsnapshots lets you delete snapshots of a certain size. tmutil deletelocalsnapshots lets you delete specific ones. (Google these commands for the details).
Now, is this a bug or a feature as far as MaintenanceTool is concerned? That's debatable. Whatever low-level free space call Qt is using is clearly using something different than what the Finder itself is using. If Qt used the same call, would the OS then purge those local backups as needed? Who knows?

That's likely a point worth mentioning on the bug report system.
