I am planning on selling my early 2008 MBP and buying a new 15" 2.2 this week, but this was my first mac, so I have never transferred from mac to mac. Will I need to install programs and everything again? (Office, Photoshop, etc...) or can I just use the time machine backup and have it do it for me? Will they be authorized and everything, or do I need to unauthorize them from the old one, and all of that fun stuff? Will a time machine backup work well this way, or do I need to use migration assistant? I will be doing a clean reinstall of the OS on the old one, so I want to make sure it will all work well because I might have to sell the old one a few days before I get the new one. Thanks for your help!
