I have a Macbook Pro 15 "- 2011



Processor 2.2 GHz Intel Core i7

Memory 8 GB 1333 MHz DDR3

Graphics Intel HD Graphics 3000 512 MB

Software OS X 10.8.3 (12D78)



After the 10.8.3 update started to show, screen sometimes white, sometimes blurred the picture without locking the mouse, the screen becomes inoperable, displaced, returning only after you restart the Macbook holding the on / off button.



Anyone else had this problem?


Help please

MacBook Pro, OS X Mountain Lion (10.8.3)

    Yes, I have the exact same problem! I believe it's a bug Apple introduced in the 10.8.3 update.


    Have you found any kind of solution?

    Try resetting the PRAM and SMC.


    Restart the computer holding down the command - option/alt - P - R keys before the grey screen appears. Continue to hold until you hear the startup chime for the second time.



    Reset NVRAM/PRAM


    Try an SMC reset. The article covers when this is required, but doing this will not affect anything.


    Reset SMC


    If the problem is still there, try booting into the Safe Mode.  Shut down the computer and then power it back up. Immediately after hearing the startup chime, hold down the shift key and continue to hold it until the gray Apple icon and a progress bar appear. The boot up is significantly slower than normal. This will reset some caches, forces a directory check, and disables all startup and login items, among other things. If the system operates normally, there may be 3rd party applications which are causing a problem. Try deleting/disabling the third party applications after a restart. For each disable/delete, you will need to restart if you don't do them all at once.
