I have an early 2008 24". This thing has served me flawlessly until I first installed Mountain Lion. It's a 3.2Ghz, 4GB RAM, with now, a 120 GB SSD, with 100 GB free at this time. My only issue ever, was that my HDD failed a couple of years ago. Once I installed ML, I started having the expected issues with program compatibility and what not.

 

Disk Utility is returning no errors. Activity monitor is almost completely idle, meaning that no program is taking any more than 1/10% or so. I had no issues with this thing until I decided to upgrade to ML since they started phasing out the programs for Snow Leopard. The first time I installed ML, I noticed it was slower. I've switched back and fourth to SL at least three times, but I get the exact same behavior. I've also changed from HDD to SSD a few months ago, thinking that would help, but yeilded no performance increase.

 

I run a constant 5Mb/s or so network speed and have tried various networks, so the connection isn't the issue. The main issue seems to be when I click a different web page, or click to work within an application: I get the beachball for 15, 30 or 45 seconds. Not every time, but a lot of the time. It's the same behavior no matter, SL or ML. Shortly after wiping the system, with no connection to my other drives, it will start this. It's as though Apple has preordained this behavior. Ever since the inception of ML, I have had nothing but problems. Do I need to buy the latest model or something? If I had another $3k to spend, I'd experiment, but my machine has been flawless, so I expect it's a "compatibility" issue. Please help me.

    Mountain Lion is fully compatible with 2008 iMacs, I suspect either corrupt download that resulted in a corrupt install or a hardware fault. However you may have a hardware fault that may need to be professionally diagnosed. To see if there is a hardware issue run Apple Hardware Test in Extended mode at least 3x back to back. AHT isn't 100% reliable but it finds errors they are correct, if it doesn't that only means you need to take it into an Apple Store or AASP to be profesionally diagnosed.

     

    Good luck.

    It sounds as if you erased the computer's hard drive and reinstalled Mt Lion. If so, did you create a new account and begin using the computer without using Setup Assistant or Migration Assistant? If you restored software and your account it is possible you also restored the root cause of your problem - a plug-in or driver or incompatible startup application. If OTOH you simply installed Mt Lion and began testing the computer it soundsmore like a hardware problem.
