the computer uses to keep track of information on your disks. Manually

Problems working with programs

following suggestions in order until the computer starts up normally:
1. If the computer freezes, you can try to quit the program you’re using by
pressing the keys x, Option, and Esc on your keyboard. Click Force Quit
in the dialog box that appears. (You’ll lose unsaved changes in that
program’s documents.)
Immediately save all open documents and quit all open programs, then
restart the computer.
