I'm not interested in breaking the EULA, so want to be sure this is OK: One household, several Macs, all with different Apple IDs. I've burned my downloaded copy of Lion onto a DVD and would like to know whether I am allowed to load Lion onto each Mac with the DVD and register it with each Mac's Apple ID? Do Apple allow this? If not, is the only "approved" way to login to each Mac with my own ID, download and install it, and then logout again? To be honest, I can't really see what's wrong with doing the first option as Apple seem to allow users to install one copy on all their household Macs, except that it means Apple gets less downloads for their stats (if they even measure that). Does anyone know?
