Why is the system folder so big?
I bought a mac mini with 250GB but really, I only have 100GB usable storage. The manage option does not help as System is greyed out. Also there is a discrepancy, the below screenshot says 147 but under the manage panel it says 100GB.
How do you clear that out without using softwares like DaisyDisk? Even with DaisyDisk, how do I know what to delete?
Mac mini 2018 or later
