I got a new iMac back in June and I restored a backup of my MacBook Pro to get it going. My MacBook Pro had gfxCardStatus installed, which obviously it doesn't support my iMac. Every time I start up my iMac I get a window stating that "You are using a system that gfxCardStatus does not support. Please ensure that you are using a MacBook Pro with dual GPUs. Now, you might simply tell me to drag the application into the trash from the Application folder, but it's not there. I cannot seem to locate any hint of gfxCardStatus on my system. Does anyone have any ideas on how to remove it from my iMac?
