Hello, Okay, so I have a PBG4, I'm running Leopard and iT 7.5. I use Menu Meters, so I'm regularly aware of my processor usage. Before Leopard or iT 7.5, when iT was idle (i.e. just sitting there, not playing anything, etc.) I would see my overall processor usage drop to a few percent. Checking Activity Monitor, iT would usually be in the 0%-2% usage category. Now, however, so long as iT is running I never see my processor usage drop down like that. Checking Activity Monitor, I find that even when iT is idle, it's still registering about 20% CPU usage. Used to be that I'd be hard pressed to get it to use 20%, regardless, except when accessing the iTS. So, does anyone have any ideas what iT is doing, and how to get it to stop? Thanks!!
