system data is taking up half my storage I have no space left on my computer. Out of 250GB, 137GB is system data. I've used a disk cleaner app (Buho Cleaner), but it didn't make a difference.

System Data I use a MacBook Air M1 with 256 GB SSD, and in recent days, this thing called “System Data” has gone from taking up 50 GB to 140 GB. Now my storage is full, and I don’t know what to do.

The final word from Apple on Managing the " Other/ System Data “ Category

Other / System Data: Contains files that don’t fall into the categories listed here. This category primarily includes files and data used by the system, such as log files, caches, VM files, and other runtime system resources. Also included are temporary files, fonts, app support files, and plug-ins. You can't manage the contents of this category. The contents are managed by macOS, and the category varies in size depending on the current state of your Mac.

Thanks, I solved my problem, I used "command + shift + period (.)" and arranged by size and , lo and behold, the "cores" file was taking upon 1.6 TB.

As it turns out, I had a camera viewing app (SmartPSS) that was generating a 10 GB core dump every time I quit.

Deleted the core dumps, updated the app and good as new.

BTW, I found it by trial and error as I could not find out how to read a core dump.

I just left the finder window opened and watched to see if any news core dumps happened as I used various apps and I got a new dump whenever I viewed my cameras remotely

Thanks, but I found it in the Core file, I am getting 2-5 core dumps a day at 7-10 GB each, the core file was 1.6TB

Any ideas on how I see what is causing the core dumps?

Found the culprit, or at least one of them.

My camera monitoring software generates 1-10 GB core file every time I close it, it is called SmartPSS

Is there some Third Party Software installed that came with the Camera.

If so, that would be the first course of action to explore - Developer Software

Yes

It is called SmartPSS

I need to use it but now I will just delete the core dump every time I close it

I know that is just a workaround but I can’t find an updated version of the app

Have you checked the local snapshots for TimeMachine in Terminal? That ate up a TON of my HD space.
