TLDR: Just let the OS handle its own resources.

My M1 mini was going strong with less ~5% free space, typically ~150 GB purgeable (on a 512 GB SSD). And no drive problems — I’m able to monitor via DriveDX.
That is correct - even in case when many things point that system behaviour is not correct. Manual intervention - without knowing the root cause - can cause more problems...

Thanks for the articles. I will read them later. Maybe this all will make more sense then.

In my opinion the OS handles it wrong when offline data from a 3rd party cloud drive (more than 600GB) does count as free storage, when I look into System Settings/General/Storage and as purgeable when I look in Finder and Disk Utility.

I now uninstalled the Proton Drive app and moved all data in my user folder. Now the same data is there as Documents and purgeable data went up to 968GB from about 630GB.

At least the available storage numbers are identical now everywhere. It was 870 GB and red color was for Music before, that is missing now completely in the graph. On the other Mac it's only there and missing in the list.

But I don't have problems with never ending calculations. Also never had before.

I found this in an app about purgeable space. But am not sure what it means. The services in that list block storage they already used, especially when the disk space is low?
