Hi guys, I weird thing happened to my MBP when I booted up. Look at my video on YouTube, I'm showing some footage of what happened using my iPhone camera. http://www.youtube.com/watch?v=Zotl5NIAXuY Btw I'm running ML 10.8.1
No, it's not a virus, since none exist in the wild for Mac OS X. It's a graphics issue. Have you restarted your Mac since it appeared? Mac Virus/Malware FAQ LOL!
I rebooted, and everything is fine again… Should I really bring it to Apple or not? Since the problem has not occured since.
Use the hardware test that comes on the install disks that came with your mac. That could give an indication as to whether something is faulty with the hardware or not. Also, if you have it, a test with tech tool deluxe might be worth it, but don't worry if you don't have it. If it happens again, or results of the test show something, then I would take it in to apple. Otherwise, I would just dismiss it as a one off glitch/blip.
