I would like to install iLife '11 on 2 user accounts on the same computer. Will I need to purchase the iLife '11 Family Pack or will the single user edition work? TIA.
No, as iLife will be installed into the Macintosh HD / Applications folder, thus it will be accessible on all the accounts you have on your Mac. Its the same with any other application you buy.
