I am told I only need to purchase one copy of Mountain Lion and I can upgrade all my existing Macs with this. Mountain Lion came on my new computer so technically I purchased it. However, when I log into my App Store it is not listed so I can't figure out how to share it with my 2010 iMac that is running Lion. Am I not eligible?
