How to Clean Huge “System” Storage on Mac

Mac “System” taking up too much space in macOS High Sierra or Mojave? here are some free methods to clear the huge “System” storage on your Mac.

Some days ago, I found one Reddit user’s post telling the “System” taking up a huge space on Mac. It was the first time I met the Mac “System” storage problem. And it was described as follow:

Hi Mac Users, System is taking an incredibly large amount of space. I mistakenly loaded heavy video files to Numbers and the hard disk immediately filled up. Any help accorded will be highly appreciated.

After I checked my computer storage usage and I was surprised to find my “System” is also taking an incredibly huge space – 43GB of the total 120GB on my MacBook Air.

As well known, the Mac operating system usually takes up from 8GB to 13GB. So I don’t think my Mac “System” storage could be that huge, so I searched to find how it defines  “System” storage for a Mac, and how to free up that storage.

What is in the Mac “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.

Sometimes, your Mac may mistakenly put other sections into the “System” storage. 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. 

And after I clicked the Manage.. button on the top left of the bar, it showed the real system storage was taking only 29.3 GB. And there were two new categories named “iOS files” and “Music creations” being separated.

  3. Do a Spotlight reindex.
  4. Disable iCloud Drive.
  5. Delete an iTunes Extras file under the movies tab in iTunes
  6. Update to upcoming Version 10.12.3.
  7. Restore Mac and set it as a new Mac. (Not a good way because it will erase your device and lose everything)
