button on the top left of the bar, it showed the real system storage was taking only 29.3 GB. For instance, my mac made the mistake of failing to exclude the “Music creations” and “iOS files” (iOS backups) from the “System” storage, so that I get a huge “System” on the storage bar.Īnd after I clicked the Manage. Sometimes, your Mac may mistakenly put other sections into the “System” storage. The “System” on your Mac storage bar stands for that space your macOS operating system used, including the system itself and the caches and cookies it generated while driving on your computer hard drive.

Once you do that for all of your listings, you should be able to run sudo tmutil listlocalsnapshots / in Terminal and see an empty list.

macOS is supposed to deal with this automatically, but I like to speed up the process so I can have a better understanding of what is using my disc space. The problem relates to on-disk Time Machine backups, and how macOS stores them. Thanks to an Apple support forum, I found out you can do some terminal tricks to fix this. Do you ever look at the amount of space used on your computer in High Sierra and know it’s completely wrong, especially after you delete some old files? This has happened to me often.
