Hi guys, really excited to just of got my first apple laptop I am fairly new to the mac however (only just switched a few months ago) so I have a few questions: 1/ I would like to upgrade to Tiger, the system is 900Mhz,has 256mb of ram, 40gb HDD and is currently running 10.2.8 (jaguar??) I was wondering if I could upgrade to Tiger using the Tiger install disks that I got with the imac c2d or is there an issue with this being a laptop and ppc ? I really dont have much of a clue about this kind of stuff with a mac, when I upgrade to Tiger I would also like a fresh install, there are no files I wish to keep, this presented a problem with my old xp laptop for drivers. Will the same happen when I upgrade the ibook? Should I format the HDD before attempting to upgrade to Tiger? If so how do I do this? 2/ I would like to install an airport card. Would I be able to install an Airport extreme card so that I can use 802.11g? Is the airport card even user installable? If so how? Many, many thanks in advance. And I appoligise for me being a 'noob'
