Mac Sierra - Not able to start in safe mode I am trying boot my macbook pro in safe mode with following instructions however, once it boots up and I login. I see it's still in normal mode. 


Shutdown the mac
Press Shift Key 
Click Power Button 
Once Login Screen Appears, release Shift key 


How to check 
Inside System Information go to Software and check Boot Mode. 

Boot Mode is alway normal.
Press Power on

After your hear the boot chime...

HOLD Shift key till it is in the Safe mode.

If it is not working lets try other start up modes like Verbose 

Turn on your Mac, then immediately press and hold Command-V. 

or Single user mode Turn on your Mac, then immediately press and hold Command-R

Still nothing ! Reset your SMC and NVRAM.

Rare situation, your EFI portion on the SSD is Brocken. To fix it Back up your data and reinstall OSX.
