Yesterday I’ve upgraded to Mac OS X High Sierra and immediately noticed higher Storage usage after that.
Upgradation went very smooth without any issue. So far I’m loving it. With new APFS (Apple File System), my 13″ Mac is so much faster and light.
After playing with new OS High Sierra, I’ve decided to fix that System Storage issue.
So why this higher System Storage usage?
It turned out, during upgradation process, macOS creates time machine snapshot. Ideally system should remove snapshot once upgrade process completes.
But because of some Time machine bug it didn’t remove snapshot in my case and it consumed almost ~250GB system storage.
How to fix this system storage issue?
We need to find and remove snapshot stored in flash storage. Let’s get started.
Step-1 List all snapshot.
Command: sudo tmutil listlocalsnapshots /
You should see result like this: com.apple.TimeMachine.2017-11-28-214807.
You may see more than one snapshot in your case.
Step-2 Delete all / specific snapshot
Command: tmutil deletelocalsnapshots 2017-11-28-214807
Repeat the process if you have more than one snapshot in your system. That’s it. Just try rebooting your mac OS X high Sierra and check storage again.
Hope this article helps you fix Mac OS X System Storage issue.
