When I returned to my mac at night, I got the notification that my startup disk is full. Coming to check, I saw that the "system" is taking nearly 155GB of storage. I have tried searching the entire drive for large files, but did not come across anything other than what classifies as "documents".

  • MacBookAir6,2
  • Intel Core i5 Dual Core, 1.4GHz
  • 256GB Flash
  • 8GB RAM
  • MacOS Sierra 10.12 16A323

MacBook Air, macOS Sierra (10.12)

Download from the Internet OmniDiskSweeper and Grand Perspective (both free) and open them. They will show all of your files and the respective sizes.


Transfer to an external HDD the files you do not want on your Mac or delete them.


Do not forget to empty trash. Only then is space allocated for additional data.

Both applications will tell you what you have on your MBA. If you click on a category in the ODS application, you will get a breakdown of that particular category. If you keep on doing it, you will eventually arrive at the smallest elements so a given file. You yourself should be able to determine if there is something missing by comparing with the file via Finder. here is the output from my MBP:
