I inherited an old Mac Mini that had a failing hard drive. It supports up to OS X Lion, so I purchased a license for Lion via the Apple Store. I was hoping to take the download and make a USB stick out of it in order to install on the new hard drive I put in. I added that to my Mac App Store account, but when I attempt to download it from my Macs running Yosemite, I get an error that it can't be installed on this Mac. Does anyone know of some backdoor method to download the setup file from a Mac running OS X later than the one I'm trying to download?
