I recently installed two SSDs in my Mac Mini and configured it as Raid 0. I have a USB stick that Ive been using on my laptops to install fresh copies of Mountain Lion when needed and it works well. I tried to use it on my Mac Mini and it said the operating system is not compatible. I assumed that maybe it was because the USB stick has a copy of the mountain lion installer thats meant for a laptop. Therefore I did the internet recovery and got my Mac Mini running. I decided it would be wise to make another USB installer for my Mini. So I went to re-download Mountain Lion on my Mini from my purchased section on the App Store and it says, The purchase could not be completed. Mountain Lion is not compatible with this computer. Has anyone else had this issue? Is there something I'm missing?
