More than 120 GB Hidden space in Mojave

My mac is eating up all free space and I have no clue where it's coming from. I have used tools like DaisyDisk or OmniDiskSweeper to find any folder/files which might be taking this space, but there are none. Only DaisyDisk is able to see there is 120GB of Hidden space but since I'm using the free trail I'm unable to see what that is.

Here is what I've done so far:

• Disable TimeMachine
• Delete local snapshots
• Checked for mobile backups
• Checked for hibernate file
• Re-index spotlight
• Find big files/folder with tools like DaisyDisk
• Check for errors with first aid in disk utility

All without luck. I've read similar topics on this and tried all what I could find. When I delete an additional 10GB, it' usually eats it up within 1 or 2 days.

Solution 1:

You seem to be using the Mac App Store version of DaisyDisk. Download the stand-alone version (https://daisydiskapp.com/downloads/DaisyDisk.zip), it has more features. Then use the "Scan as Administrator" command to reveal the hidden space. Also before scanning make sure you grant DaisyDisk "full disk access", if you're on Mojave or Catalina. To do this, go to DaisyDisk Preferences > Full Disk Access tab and proceed with drag-and-dropping as instructed there.
