I have a 1T drive, and it normally uses 400 GB space. After the system upgrade from 10.13.5 to 10.13.6, the system now tells me the disk is almost full:
The system uses 870GB, almost the double what it used to.
Maybe there are some backup files in here, because sometimes disk space will be the correct size. I think a backup file is deleted at that time.
So what can I do to stop this from happening?
