Hi,
I'm on an early 2011 Macbook Pro here and recently started experiencing weird display warp/freezes that required a hard shut down/restart.
Initially this fixed it but over a period of a few months they've become more frequent to the point where it's now very unstable.
I've so far done the following trouble shooting with no effect on the problem:
1. Recovery Boot, Verify Disk, then Repair disk
2. Safe Boot mode
3. Command-S Boot, > Run fsck -fy...twice
4. Reset the NVRAM
None of this has had any effect.
My next plan was to completely erase my HD and re-install Mountain Lion (I'm currently running 10.8.5 and have the original instal disks > 10.6.6) I'm all backed up but I've run into a wall trying to do this step.
Here's my problem:
When I boot into recovery mode (command-R) and choose the re-install OS option I go through the steps until I'm asked for my Apple ID. I type it in and get the following message:
"This Apple ID has not purchased Lion"
This got me thinking that maybe I used an old ID when I first purchased my computer. I dug around and sure enough I have an old Apple ID I'd forgotten about associated with an alternative email address. I tried again to do the recovery/OS set up, got to the same sign in with Apple ID stage and am now receiving the following message:
"This Apple ID has not yet been used with the App Store. Please review your account information" When I click 'Review' nothing happens.
So I logged on to this old ID and tried updating my preferences, tried the process again but am still getting this message.
I've spent hours trying to fix this.
Any suggestions?
Peter
