I was trying to install the final version of yosemite on my macbook pro (13 in mid 2012). When it restarted it went to the apple logo screen with a bunch of black writing on it. It keeps restarting to this screen. I've tried resetting the pram and the cms or whatever the other thing is called but that didn't do anything.
Got a tip for us?

Looks like your computer repeatedly crashes on boot
Try Apple HardWare Test; if successful then reinstall OS.
