Resolved Not regaining used space when deleting files. DaisyDisk says 180 GB of "Hidden space"

[applemagnus]

I noticed that my mac suddenly was running short on space, and I hadn't been installing any large files lately. When i tried deleting 50+ GB of files from my SDD, my available space had gone from 62 GB to 58 GB. I tried checking DaisyDisk to see what was taking up all the space and, as you can see in the image below, a large chunk of my SDD was dedicated to hidden space.


I then tried searching the web and found this tread: https://forums.macrumors.com/threads/1310197/ The problem is the same, but repairing disk in Recovery Mode didn't fix the problem, it only regained about 10 GB of space.

If anyone knows how to fix this I would be very grateful. Thanks in advance

If you're wondering what "Other" category in the storage tab is about, this may help explain:

What is this "Other" in the storage tab? What is eating my space​

For space issues not explained by the above, there are a few things you can try, some of which may or may not apply:

• Begin by restarting your computer as a first step. This sometimes resolves issues.
• For Time Machine users on notebooks running Lion or later, space may being consumed by Time Machine local snapshots, which can be disabled by entering the following command in Terminal: sudo tmutil disablelocal.

• Check to see if some of the space is being used by your sleepimage file.
• Search with Finder to see if the space is being consumed by a very large file or several large files. Adjust the 50GB in the illustration to whatever size you deem appropriate.
  
• Use OmniDiskSweeper, JDisk Report, Disk Inventory X, DaisyDisk or GrandPerspective to see how space is being used on your drive. Some of these apps may show more detail than others, so try several.
• Check your drive with Disk Utility: Using Disk Utility to verify or repair disks
• Try re-indexing your drive: Spotlight: How to re-index folders or volumes

For anyone reading this tread in a later stage, I do believe I have fixed the problem. I tried scaning my SSD in DaisyDisk as administrator. This showed my that .MobileBackups was taking up 160+ GB of space. I then tried as suggested by GGJstudios:

For Time Machine users on notebooks running Lion or later, space may being consumed by Time Machine local snapshots, which can be disabled by entering the following command in Terminal: sudo tmutil disablelocal.

Entering the command:

sudo tmutil disablelocal

deletes .MobileBackups and freed up 180 GB of space.
