Hey all - Yes I'm a newb to the Mac world. Hoping to get some simple help with what I would see as a quite simple question. I currently was given an Mac iBook G3 900MHz and it's currently running 10.3.9. Some software that I was looking to install requires 10.4.9, I'm not familiar with the names yet although I believe 10.3.9 is Panther and 10.4.9 is Tiger? Is it possible to put tiger onto this laptop? Thanks!
