In the next days I'll change my Mac with a new one (IMac 21").
How to move PS and LR to the new one?
I need to be autorized by Adobe?
You can install Creative Cloud apps on any two machines but cannot run them simultaneously.You may install Creative Cloud Desktop app from Download Adobe Creative Cloud apps | Free Adobe Creative Cloud trial and please follow the below steps to download Ps cc 2015 and lr cc.
I hope it helps!!
In few days I'll receive the new iMac and I'll use your suggestions. I'll keep u informed.
