You can try re-indexing Spotlight.

System Files too big Hi all, I've done everything the book tells me to do.. backed up using time machine, reviewed my file folders, but I still get a system files hard drive usage of 166 GB, when my operating system files are only 16 GB. This is consistent before and after reinstalling Mac OS and time machine. How can I reduce the enormous amount of room taken up by system files? Sincerely Paul

System files taking up too much space on my HD. I got a prompt saying that I was running low on HD space. For my surprise I found out that the system files are taking up most of my HD space. I use the computer for home, so I don't run any heavy software, just the usual, MS Office, iTunes, Chrome, etc. This is a new Mac and on my previous machines I don't remember that the system files would take the majority of the HD. Does this seem normal? Running Monterrey Any suggestion would be greatly appreciated! Thanks. Andres [Image Edited by Moderator to Remove Serial Number]

HELP System files consuming 80% of computer storage How can I clean up my MacBook Pro's system storage? It's consuming 88gb and is so full I'm unable to download storage updates. Everything else has been "managed" with the options available but this needs to be resolved!

Obviously there is no way 166GB's of data could be located in the system files.

Restart in Safe Mode, then restart normally. That should clear caches and free some space.

One other source of large system space is Time Machine local snapshots.

Do the following command in Terminal. What does it tell you?

tmutil listlocalsnapshots /
