Hi, I did a clean install of ML and restored my apps and data from Time Machine (no settings restored though). I had been waiting for ML mainly expecting a that my 2009 iMac would get back to its original speed... it didn't change anything. Still slow on boot and lagging a low when scrolling through iTunes movie section. I've given up on trying to increase the boot speed, but I'm hoping that someone has a tip to speed up my itunes scrolling... Anyone? Thanks!
