Hi guys.


My MBP has started - infrequently - to show some kind of grey bar of doom on startup.


It looks a bit like this one here...  This isn't mine, this is some other poor soul with the same problem who's in Google Image Search


This seems to happen most often when rebooting out of a Boot Camp windows session, when I've been playing games (machine is thus very hot).  I've only had it once when booting the machine from cold.


It takes an ice age to go through every time, but if I force power off and power back on, the bar is gone and the machine starts normally.


I can't find anything in the system logs, which is super unhelpful.  How do I diagnose what is going on, and how do I go about fixing it?

    Off the top of my head it could be you need to insure your drive with OSX is the startup volume.  Goto system preferences and select you startup volume.  You could also repair the disk and then choose your start up disk.  Shut down your computer.  Then restart holding down on the option key until the bong sound and choose your recovery disk and then disk utility and repair disk, after repair is complete select your start up disk (do NOT repair permissions here).

    Another thought was do you have a lot of startup items, or your HDD is starting to ware out (fail).

    If you live close to and Apple store they will diagnose it for FREE even if its out of warranty.  Most likely if nothing is found wrong (hardware) they will suggest a reinstall.  If you decide to reinstall from scratch I'd suggest you zero out your drive which will remove the recovery software also, and need have a copy of the operating system on DVD.  If your using Lion or Mountain Lion you can download OSX BEFORE zeroing out your harddrive and put it on DOUBLE LAYER DVD single layer will not work.

    MAKE SURE YOU HAVE AT LEAST 2 backups of the files you want to put back on your computer!!!!!!!!!

    1. Reset PRAM.

    2. Disconnect all peripherals and try starting up.
