I currently use LR4 (upgraded from LR3) and CS5 on my Macbook Pro.
I am likely going to purchase an I-mac in December.
I wish to install LR4 (LR3 + upgrade) and CS5 on to the I-mac and retain same on the MacBook pro too.
On the I-mac, there will be 2 user accounts (me and my wife).
Will these programmes be limited to my user account only or are both users on the I-mac able to use these products under this 1 license, bear in mind that I still need both these programmes to operate on my MacBook Pro as per current setup too.
Generally speaking, you should be able to install commercial Adobe software for use on up to two systems... And in Windows, when you install any application it gives you the choice of installing it "Only for me" or "Anyone who uses this computer" (all users).
Add the two together and you should get what you want.
