Hi guys, my MaPro keep starting into Safe Mode and even rejects my password, please help!!

To start in Safe Mode, hold down the Shift key at Startup.

If your Mac starts in Safe mode by itself, and rejects your password, perhaps your Shift key is stuck -- your password is case sensitive.

Reset the NVRAM > About NVRAM and PRAM

If that link doesn't work, follow the instructions here.

1. Shut down your Mac.
2. Locate the following keys on the keyboard: Command (⌘), Option, P, and R.
3. Turn on your Mac.
4. Press and hold the Command-Option-P-R keys immediately after you hear the startup sound.
5. Hold these keys until the computer restarts and you hear the startup sound for a second time.
6. Release the keys.

After resetting NVRAM, you may need to reconfigure settings for speaker volume, screen resolution, startup disk selection, and time zone information.
