I'm using a time machine back-up to transfer stuff on my iMac to a new Macbook Air with limited space. Will I have the option to select which stuff to migrate because there isn't enough space to migrate everything. My goal is to have certain software (Office, Filemaker) transfer over so I can I have full functionality with those programs on my Air. I realize that I will have to de-activiate the license on one computer in order to use the software on another, but wanted to know if I will get the option with a time machine back-up to manually move stuff.
