MBP boot stuck at 100% loading screen For a day now i can't boot my Mac El Capitan. It halts on this screen:



What I tried: 


NVRAM reset
CommandR Disk Utility checked SSD, I can launch Terminal and browse the files on SSD
Reinstall OSX; reinstall finished, but when it restarted it gives same result as on pic above.
Apple Hardware Test app didn't find failure


Not sure if it's since an OSX software update. The loading bar goes fast as usual till ~70% then it slows down and goes to 100% in 2-3 minutes then nothing happens. 

UPDATE: Verbose mode stuck at "pci pause: SDXC"

Any other fix to try? ty
The problem is unsupported .kext files and you need to remove them to get OS X to boot.  Just moving them to a different directy will have the same effect but will allow you to copy them back.  This article had the solution for me: OS X El Capitan 10.11.x Hanging on Boot

mount -rw /
cd /Volumes/Macintosh\ HD/Library/Extensions/
mkdir Unsupported
mv *.kext Unsupported
reboot


After solving that issue, I ended up with a black screen where I could only see my cursor.  If that happens to you, try the solution found here:  Black Screen But Can See My Cursor
