Yes, you can create a bootable flash drive from the InstallESD.dmg (like in Lion). Then use it on all your Macs to install ML. I think the current Mac-limit is 5 Macs.Can someone tell me how is the multiple upgrade of ML works? i want to upgrade my macbook pro and macbook air. I also want to upgrade the iMac at my parents house. I can upgrade to ML with the single purchase?
No, this is a waste of time. Use the USB (InstallESD) option-much faster (see above).so is that mean I can login with my ID on all 3 macs and I should be ok?
Their isn't an authorization limit (after you download it, you can install it anywhere). In the T&C, it says you can install it on all the macs you own.Isn't there a limit in the terms and conditions? Not sure if there's an enforced authorisation mechanism like iTunes, but you can definitely install on at least 4 machines.
Yes, this is fastest option. See also:ok thanks for the input guys.. So login with Apple ID on AppStore, Buy ML and download the ML dmg file. Transfer the dmg file to Flash Drive and install on the other two macs.
is that what i'm suppose to do?
