I plugged in a 1 TB Hitachi USB drive to my MacBook Pro, the rainbow circle icon in Finder spun for about 1 minute, then the whole operating system froze, even closing the lid doesn't make it go to sleep.
How can I reboot my MacBook Pro?
- There's no Delete key for a CTRL-ALT-Delete.
- I can't find a reset button on it.
- I can't seem to turn it off and it has at least 6 hours of batteries left.
- Command + Option + Escape didn't work.
