    Hi - I have a 2013 MacBook Pro with win7 installed with bootcamp.

    For about a month I have been using win7 only and yesterday I tried to run The apple operating system but it fails to boot.

    I get the grey screen but when the bar reaches the end the computer just turns off.

    Tried the check disc utility which is finding no errors. Tried I start in safe mode but that fails too.

    Can't understand why win7 starts fine but apple OS won't!

    Please help

    Grey screen and bar reaches the end? :confused: That's not the normal boot process...it sounds like it's trying to perform an SMC or firmware update and then shuts off, but that should only happen once.

    Since it's a 2013 you still have a warranty, if you have an Apple Store nearby you may want to see what they can figure out.

    I press the power button then I get a grey screen with a bar in the middle - the bar fills from left to right and when it reaches the end it just powers down.

    I can startup with the control button pressed and then load windows or the systems option to run disc check etc but not the apple OS
