Hello! I've searched for some time now and haven't seem to come up with a solution. I'm trying to Install leopard on my Imac, but every time I run into the "Software cannot be installed on this computer" message. Here are my specs: Model Identifier: iMac4,1 Processor Name: Intel Core Duo Processor Speed: 1.83 GHz Number Of Processors: 1 Total Number Of Cores: 2 L2 Cache (per processor): 2 MB Memory: 1 GB Bus Speed: 667 MHz Boot ROM Version: IM41.0055.B03 SMC Version: 1.1f5 I thought this would be sufficient for the installation, but I can't seem to find a solution. Is my Mac capable for the Leopard installation? And if not, what do I need to do to make it so? Thanks! EDIT: I forgot to mention - I'm using OEM Imac discs . . . would that make a difference?
