MAC system trash can not clean up
Use disk tools to verify disk permissions and repair permissions, restart and then delete. If not, turn off MAC, and then press the power in a moment after boot press option+command+r+p button four don't let go (do not use a Bluetooth Keyboard), until I heard more than 3 times on the sound after the release, it can be reset and empty the system, and then to delete.
1, in the Spotlight input disk tool.2, in the disk tool to select the current use of the hard disk.3, click on the verification disk permissions, and then wait for system testing.4, after the test, click on the repair disk permissions, and then wait for the system to automatically repair.5, after the completion of the withdrawal of the disk tool can be.
What's wrong? It is not in the terminal using RM delete..
