Buying a new iMac, want to install Mountain Lion on old iMac
I know that if I buy Moutain Lion I can install it on multiple computers. But in this case I have one iMac (with Lion) and am planning to buy an additional iMac which will come with Moutain Lion installed. Will I be able to download Mountain Lion for the old computer (since it won't show as a purchased product in the App Store), or must I buy it?
iMac, Mac OS X (10.7.4)
