Hi all. I'm new here. I need help. I have a Snow Leopard Install Disk for the 13-inch Macbook Pro model. I also have a 21-inch iMac. I have OS X Lion installed on both. I have Snow Leopard installed as a partition on my Macbook Pro, which I installed via the install disk. I want to do the same thing for my iMac but I am unable due to (seemingly) my install disk is for a Macbook Pro and not for an iMac. Does anyone know a way around this? Why won't this work? I was thinking I could change something in the package contents to alter it to allow it to work with an iMac? I'm lost. Please help. I need to use Pro Tools 8 and that won't work on Lion.
