I am running short of space on my OS partition for some large files I want to install.
I note that
I have 2 Time Machine drives. One attached to my MacBook Pro (at least when it is not being used as a portable), and a second, which is attached once a week. This was last updated yesterday.
What is using the 15G and why? What would happen if deleted it?
A second issue.
103G / but
Disk Utility says
Used 112G. Is this the sum of file sizes vs disk space used?
