    I just installed the latest update on my new Mac Pro (Late 2013). When the computer rebooted, it was stuck on a black screen. I hear the boot chime, but that the screen is black. I have tried rebooting a few times, tried resetting SMC by leaving the computer unplugged for a while.

    I tried to reset PRAM, but no matter how long I hold down the button does nothing seems to happen. Same thing with command R, which is Apple recovery. I cannot option booed to my Windows boot camp either.

    Did anyone else with the new Mac Pro have this problem when installing the latest update?

    Is my system completely screwed? I don't know how I can boot.

    In this case, 1st thing to check is the cable, make sure the monitor still connected properly.

    Thanks, I appreciate the advice. The monitor was working, and after several more restarts (and nothing else) it did finally boot. After a long time I finally got the Apple logo, and then the system did load. Upon further restarts, it does not appear to take as long. Something got worked out apparently.
