I turned on my MacBook just now and was unable to open it, I got weird text all over the screen in black, similar to something you would see if your PC failed to open and went into DOS. I tried putting in my password and after the 3rd time it finally opened. How can I tell if this was a virus or something? I don't go to funky websites or click on odd looking search entries. I don't understand what's going on.

MacBook Pro, OS X Mountain Lion (10.8.2)

    First of all forget about Virus. I can tell you that it is not one.


    How about if you provide us some the text that you are seeing maybe that might help us to understand your problem.

    I've tried to attach the photo I took but can't seem to get it to work. The beginning lines are:

    panic(cpu 0 caller 0xffffff8000eb7bd5): Kernel trap at 0xfffff8000   and then my pic cuts off


    I've got lots more lines, one says "Mac OS version: Not yet set" and something about a Darwin Kernel Version.

    If you have an install DVD for that Mac then attempt to boot from it and see if that changes anything.

    Your computer has crashed .


    Its not a virus but more likely hardware problem.


    RAM may be bad or Hard drive corrupted.


    You would be best making a Genius appointment asap.

    But its working now. If it had crashed would it be working?

    I don't remember getting a disc with it. Is that something that would have been with it when I bought it?

    That looks like a hardware-related kernel panic. In other words, something is probably wrong with your machine's hardware. It doesn't matter that it's working now, sometimes hardware problems can come and go, but it will probably get worse. I would agree with Keith, you need to get that machine checked out by Apple's techs.

    If it's a newer model that shipped with Lion, you wouldn't have received an installation disc, If I were you, I would run the Apple Hardware Test on the machine and see if it reports any errors. If it does, or if the problem happens again, you can then take your machine to an Apple Store or an AASP and have further diagnostics run.


    Good luck,
