How do you fix a Mac book pro after installing the new software, but it won't log on? I can not get to my desktop
MacBook Pro, OS X El Capitan (10.11)
it won't log on?
It's a very long road between mashing the power button and seeing the desktop.
at what point is it doing things differently from what you expect?
This same thing is happening to my Mac. I turn on the computer put in the password to login and it gives a sort of error. I habe attached an imag.
You problem appears to be happening early in the boot-up process. Launchd (the thing that launches everything else) fails to load.
You probably have a corrupt image of Mac OS X, and will likely need to re-install Mac OS X (right over the version you are running now).
You can do this by holding command-R at startup, and choosing re-install Mac OS X as an option.
This could possibly be caused by a memory failure.
