Hello all,

for the past month my macbookpro will not start up past a white screen & I can only start up in safe mode. Today I tried to start it normally & got the following message Pic also attached:

Can anybody suggest what the problem and solution is please? I am in a remote area at the moment so going to a apple store is not an option. Thanks!

Hello and welcome.

From the log, you are running Mac OS X 10.6.8 Snow Leopard on a MacBook Pro (15-inch, Early/Late 2011) correct?

That is a kernel panic. There are many causes:

-OS X is corrupted
-HD is failing
-RAM is failing
-Logic board is failing

-Do you have an external HD with OS X on it that you can try to startup from?
-Do you have a current Time Machine or other backup of your data?

Hi Cory, thanks for the reply, yes that is correct.

I doubt it is the HD as I just changed it 2 months ago, so my best guess would be any of the other 3 possibilities you mentioned. I have all data backed up on an external HD, but no HD with OSX on it.

I am going back to 'civilization' in 5 days, maybe a good option to get it to an Apple store, any thoughts?

No worries.

It still could be the HD, since they tend to fail within the first 30-90 days if they are defective from the factory. However, since it does startup in safe mode, I would lean towards OS X being corrupted. Since you have your data backed up (well done), if you have the install disc(s) with you, you could try a reinstall over the top of the existing OS. The Early 2011 models require at least 10.6.6/10.6.7 Snow Leopard, the Late 2011 models require 10.7.2 Lion, depending on the model and manufacturing date.

You could also try:
-Run Apple Hardware Test
-Repair Disk Permissions and Repair Disk - startup from the install disc.

If the above don't fix the issue, then it will require a trip to the Apple Store. If you get it working again, it would probably be good to have it checked out anyway upon return, especially if you are currently in an electronics unfriendly environment.
