Problems With My MacBook?
Recently I have been having problems with my Mac, but I've decided to come to the forums before I schedule a Genius Bar appointment. There are two main problems:
----------------------------------
System Specifications:
Late 2009 MacBook 13-Inch
2.26 Ghz Intel Core 2 Duo
4 GB 1066 MHz DDR3 (upgraded from 2 GB)
NVIDIA GeForce 9400M 256 MB
OS X 10.8 (12A269)
----------------------------------
1. My Mac randomly 'freezes' after waking up from sleep. I cannot open any applications. They just sit there and bounce, and the light blinks. When I try to make my computer go to sleep from this point, it is unresponsive. Only choosing shut down will fix the problem. This happens about 1/3 times the computer goes to sleep.
2. When I shut down my Mac, from either freezing or normal, it hangs. I can move my mouse around, but the screen is an off-white, characterisitc when you turn a Mac on or off. I have to hold down the power button to turn off my Mac from here. When I turn it back on and try to log in, I of course get a message of improper shutdown asking me if I want to open applications that I had open (none). This happens about every shutdown.
How can these problems be fixed? I would call myself a mid-advanced Mac user, so I know Terminal and disk utility, etc.. I was thinking of repairing permissions, but for all I know that might not do anything. Could the hard drive be corrupted? I literally have no idea. I recently upgraded to Mountain Lion, and so I don't know if it could be software or hardward problem. I was not planning on buying a new Mac until college (two years), so I hope this isn't a fatal problem. Please provide suggestions to fix my Mac, Thank You!
Not to mention, but my MacBook is out of warranty, so if this is a hardware problem Apple won't cover it. I upgraded the RAM after the warranty expired, so whether I upgraded it or not makes no significance. The problems point toward a corrupted HD, so I don't telll me I shouldn't have messed with it internally 🙂.
