Internal iMac Drive is Near Capacity

IMac internal drive shows only about 10% space left. In checking the files and folders in the drive by using the “get info” on the iMac for each file and folder on the drive, I can’t find any large file or folder. The individual folders do not add up to anything close to the total shown for the drive. Where is the large difference that I can delete to get the drive at a safe capacity?

Mac Pro, OS X 10.11

Hi Adam, a few things to check...


Have you emptied the trash lately?


Look for iOS backups…

/Users/YourUserName/Library/Application Support/MobileSync/Backup


Purging local backups

Please note that although this doesn't affect your remote backup from Time Machine, this will get rid of the redundancy (at least until the next Time Machine backup) that a local backup disk will provide. If you need such redundancy or are worried about the recovery of your data then you would be best served to let macOS determine when to purge these files.

Start Terminal from spotlight.

At the terminal type tmutil listlocalsnapshotdates 

Hit enter.


Here, you'll now see a list of all of the locally stored Time Machine backup snapshots stored on your disk.

Next you can remove the snapshots based on their date. I prefer to delete them one at at time. Once my "System" disk usage is at an acceptable level, I stop deleting but you can delete all of them if you want to reclaim all of the disk space.


Back at the terminal, type tmutil deletelocalsnapshots YYYY-MM-DD-HHMMSS , where will be one of the dates from your backup. This will be in the form of xxx-yy-zz-abcdef. Try to start with the oldest snapshot.

Hit enter.

Repeat for as many snapshot dates as required

tmutil deletelocalsnapshots / # deletes all the snapshots


Thanks to BobHarris file sizes, Applications -> Utilities -> Terminal:...


sudo du -hx | sort -h 


sudo will prompt for admin password but not reflect what you type, so hit enter after carefully tying the PW. :)
