MacBook Pro boot stuck at 100% loading screen

I tried the following but none fixed it:

• Boot to Safe Mode/Boot (press Left Shift after pressing power until the Apple logo appears) , but it's stuck to 100% still.

• PRAM reset (press Command + Option + P + R after pressing power, hold until the computer restarts and you hear a sound for a second time)

• Recovery mode (press Command + R until the Apple logo appears) then Disk Utility and run First Aid - no issues found

This appears when use command+v

I got stuck at 100% to. This is how I manage to solve the problem.

1. Reboot with "cmd"+"R"
2. Acces terminal via menu bar
3. $ nvram boot-args="-x" (this command tell your macbook to restart in safe mode during further reboot. We will disable it later)
4. Reboot and Login
5. Turn off your bluetooth (I don't know if it was really a bluetooth problem, I just disabled it)
6. Open terminal and $ sudo nvram boot-args=""
7. Reboot

Hope it helps

Nothing worked for me. The fact that I was able to get FAN started helped me fix my Mac Air. The solution is very weird. But, the fact remains. I got my MacBook Air back.

This happened to me last week. I tried everything you tried and nothing worked. I tried Reinstalling the ``current'' macOS, which was Catalina, by starting in Recovery Mode (Cmd+R) but it also failed. My last resort, and the one that worked, was to update the macOS by starting in Recovery Mode (Option+Command+R), and clicking in Reinstall, which would update to the newest macOS available (Big Sur). No data losses since it doesn't format your HD, but backing up by using the terminal in Recovery mode is advised.

Hope this could help anybody that is in such a terrible situation.
