    Does anyone know how to clear all the files in the system cache safely? My file size is upward if 2gb now and could use that space Finder>Library>Caches

    A 2 GB cache is not atypical (mine is 1.8 GB). If you clear it it will come back anyway. Maybe time to think about expanding storage. A 2 TB drive can be had for less than $100 now.

    There are utilities like Cocktail that will clear them. I don't know if you can just move them to the trash and reboot, but that would probably work OK. I just don't worry about it.

    Does a desktop Mac support hibernate? If so, you could save some space by disabling hibernate and deleting the sleepimage, which will be the same size as installed memory.

    From a Terminal session:
    sudo pmset -a hibernatemode 0
    sudo rm /var/vm/sleepimage

    or you can use an app called onyX to clear the system caches.
