hi i bought logic pro x and have it installed on a mbp . now i want to also install it on my mac pro 3.1 which has logic 9 on that i had bought a while ago. there is a apple support article that says you can install logic pro x on a second machine using Apple Remote desktop. However this is not a free software and i can find a detailed instruction manual. When i go on the appstore from the mac pro it does not offer me a logic x download, only if i buy it again. So how can i install logic pro x on a second machine without paying any extra pls?
