Things you don’t want to see on your MacBook screen
To avoid this you should do a regular disk check (as I should have been doing):
- Restart your Mac – Hold down Apple key + S straightaway – You will eventually see it boot into Unix (black screen) – When it has finished type the following command:
fsck -fy
Press Enter and let it do its stuff. This could take awhile so go make a coffee or something.
When it has finished type the following command:
reboot
And press Enter. Computer will reboot.
If this won’t work for you can use the following alternative command:
fsck -f
