Transfer CC to new MAC

You do not do anything in the way of transferring between machines.  You install it using the installation files just like you did originally.

You can install on as many machines as you like.  Of all those machines you can only have two signed in for use.  Of those two machines you can only be using the subscription on one at a time.

Download/install the desktop application, sign in, install the subscription application(s).
