Sometimes you need to delete all the snapshots that the macOS time machine do locally just because you want to get rid of something of because you need to reclaim that space. Before one could use
sudo tmutil disablelocal to delete everything and then
sudo tmutil enablelocal to enable the local snapshots again —since they are useful. However, that option is no longer available.
So if you run
1 2 3 4 5 6 7 8 $ sudo tmutil listlocalsnapshots com.apple.TimeMachine.2018-03-03-144538 com.apple.TimeMachine.2018-03-03-154712 com.apple.TimeMachine.2018-03-03-170903 com.apple.TimeMachine.2018-03-03-181447 com.apple.TimeMachine.2018-03-04-094245 com.apple.TimeMachine.2018-03-04-110835 com.apple.TimeMachine.2018-03-04-121348
You probably end up with a similar list as mine, or perhaps even longer. If you waned to free some space, you need to use the command
tmutil deletelocalsnapshots and introduce the date os each of the snapshot one by one to delete them, which it’s quite a pain in the ***.
Lucky, someone in the MacRumors forum came with a clever idea of using the terminal and the grep command. If you run:
1 2 3 4 5 6 7 8 $ tmutil listlocalsnapshotdates / |grep 20|while read f; do tmutil deletelocalsnapshots $f; done Deleted local snapshot '2018-03-03-144538' Deleted local snapshot '2018-03-03-154712' Deleted local snapshot '2018-03-03-170903' Deleted local snapshot '2018-03-03-181447' Deleted local snapshot '2018-03-04-094245' Deleted local snapshot '2018-03-04-110835' Deleted local snapshot '2018-03-04-121348'
You are going to get rid of all those snapshots in no time.
