System data taking 95GB of my macbook air

I have a big problem. Why is system data taking almost 95 GB of 120. This is absolutely ridicilous and macOS is taking 24 GB out of 120 GB so I have no space of my own things. I have tried everithing to delete it but nothing has worked. And the time machine is also not working because I can not scroll thru it. I don`t think that this is very normal and how can i delete my system data without paying anything?

MacBook Air 13″, macOS 12.5

Generally, the files in the System storage can be anything that cannot be categorized into app, movie, picture, music or document, such as:


1. Essential macOS operating system files;

2. Time Machine snapshot backups;

3. System log files and cache;

4. Cache from Browsers, Mail, photos and the third-party apps;

5. Old macOS updates;

6. Trash data and junk files.


Sometimes your Mac builds up an unnecessary amount of System files due to a bug, but most of the time it’s a normal part of how the operating system works. However, you can follow the below methods to manually reduce system storage on your Mac:


1. Empty Trash

2. Manage Time Machine Backup Snapshots

3. Optimize your Storage

4. Remove iOS Backups

5. Delete Cache Files

6. Update macOS


Hope it helps!
