Try Recovery Mode When The Mac Won’t Load
If the issue repeats and your Mac won’t turn on again, you can try some of these:
- Set your Mac back using Time Machine
- Reinstall the operating system
- Use Disk Utility to recover your drive
- Run some dedicated Mac maintenance app
All these options are available via Recovery mode—not to confuse with the Safe mode—and to enter it you’ll need to once again press a few spell-invoking special buttons. Needless to say, they are of no use if your MacBook won’t load in the first place.
How To Enter Recovery Mode:
Got to Apple menu > Restart
Wait for Mac’s startup sound
Immediately press and hold Command + R
Don’t release the keys until you see Apple logo
