My computer isn't working properly, and nobody knows why. I'm pretty good with Macs (I've been using them since the old SE 30), so there's rarely a problem that I can't fix myself. Recently though, my iMac has been running its fans up really high, and the noise was getting really annoying.
I opened Activity Monitor to try to find out what the issue was. Apple's Mail program was reporting back as using between 80 and 90% of my CPU. And it stayed that way. For hours. The CPU percentage would even go over 100%, usually to about 140%, at least once to 2000%.
For the first time in years I called Applecare. I have the extended warranty, and their tech support was very helpful at first. To sum it up, we tried these steps:
I archived my hard drive and reinstalled Mac OS X.
I erased my hard drive and reinstalled Mac OS X. (Unfortunately I lost a lot of stuff....)
Now Apple's Finder causes the problem, Mail is OK.
I drove two hours each way to drop my computer off at an Apple Store.
They replaced my RAM.
My parents drove two hours each way to get my computer back.
Apple sent a technician to my house to replace the logic board (aka motherboard).
I was given my own specialist, who sent my info to the developers and said he would call me back in two days.
A week later he hadn't called. I got a new specialist who said he'd call me back the next day.
My computer starts crashing regularly.
Two days later he hadn't called. I spoke with a person from the corporate level of Apple who labeled my case as a high priority.
My computer crashes every time I attempt to work on it.
I got a call from the second technician apologizing for not calling back the next day. His kid was sick. He instructed me to erase my hard drive and reinstall Mac OS X again. Apple is also sending a technician to my house to replace my RAM, logic board, and hard drive.
I got a call from Apple's corporate supervisor making sure that I was contacted by their specialist.
I've really stumped these guys. They don't know what the problem is, and they've never ever heard of anything like it. It persists through numerous checks, reinstallations, and replacements of crucial parts. It's been a month since I first called, and I leave for school in three weeks. I hope my computer gets fixed soon.
