Terrible performance on Mountain Lion
I got a hand me down mid 2009 MacBook which is Mountain Lion compatible, so I decided to install Mountain Lion on it. The system was using Lion and it was quite quick. After putting on ML I'm getting spinning beach balls, apps are taking tens of seconds to load, etc. etc.
The performance was so bad I thought maybe the hard drive coincidentally had gone bad, so I ran some tests on the drive using Scannerz. Scannerz pretty much came back saying "you're drive is fine." I thought maybe the permissions were screwed up, so I repaired them using Disk Utility. I tried resetting SMC and NVRAM thinking that would help but it didn't.
Can this system really support Mountain Lion?
