I know that's below the required speed but there's Leopard Assist. As can be seen on that page, it says "Uncertain" ONLY for my iMac. Has anyone done it with this iMac? Does anyone know? I'm running Panther now and, these days, that's no place to be. I want to get Leopard on my Mac before I have to <shudder> switch back! TIA for responses.
