Greetings. I'm very new to this forum, and please let me introduce myself. I have an "old" 17" Macbook Pro (aluminum), C2D 2.4 with 4Gb RAM. It came with Tiger installed and i never bothered upgrading to Leopard (well, Tiger worked very well with my software). I do mostly Webdesign and Photography, and i work mainly with Dreamweaver, Flash and Photoshop/Lightroom. The MBP has served me very well but now i want to buy an iMac 24", 2.8 with 2Gb (upgrading later to 4Gb) to have at home while i'll use the MBP on location and work. I know that the iMac comes with Leopard and the install DVD's. My questions are: - can i use the iMac install DVD's to upgrade Tiger on my MBP? Will this work, installing all necessary drivers, configurations, etc, or do i have to buy the Leopard DVD to do this? - if it's possible, what would be the best way to do this? a frsh install or an upgrade? Any online step by step tutorial of the best way to upgrade from Tiger to Leopard? I'm still pretty new to Macs and i've never installed the OS... - if i upgrade Tiger -> Leopard, instead of a fresh install, will my programs be immediately available in Leopard or do i need to install them again? Thanks in advance.
