Hi, I just bought a new MBP through the ADC hardware purchase program, so obviously I don't need my copy of leopard, and I want to sell it. I was wondering what version it is in respect to upgrade vs. full and 10.5.4 vs 10.5.5 (it doesn't say anywhere on the package.) Anyone help me out? PS. I received a badass shirt with the software too...unfortunately it's an XL...I'm a medium. Anyone know about that either?
