MacBook Pro fuzzy screen and freezes on startup at the Apple logo with half progress bar Details: MacBook Pro 2011, El Capitan.
Issue: As mentioned above in the subject. Picture Given below.
Resolutions tried so far:


PRAM Reset - Heard the Chime of reboot but still hangs the same way
Verbose Mode - Stops at AirPort: RSN handshake complete on en1
Recovery Mode - The screen in the picture below appears but after sometime, a complete blank grey screen (without Apple logo) came up, the disk seems to be spinning but then nothing.


Pretty much tried all these options: MacBook Hangs on Boot at seemingly different stages each time

There was mention about a resolution with another Mac but was not elaborated. I have a second Mac, MBP 2015. Can someone suggest what can be done?

I have also read this article, Mac book Pro [2011 model] - Screen bit distorted and greenish tint and does not boot completely after the apple logo and progress bar loads and want to check if my problem is related to this issue. 



Thanks a lot for your time and suggestions.
How about start in safe mode?

Try safe mode if your Mac doesn‘t finish starting up

Follow these steps to start up into safe mode:


Start or restart your Mac.
Immediately after you hear the startup sound, press and hold the
Shift key.
Release the Shift key when you see the Apple logo appear on the
screen.
