This morning Apple issued a press release officially announcing OSX Leopard. The software will go on sale October 26th at 6 pm at all Apple stores, or you can pre-order it online right now. If you pre-order the software you will get free delivery, and it will be delivered on the 26th (so there’s no real reason to go wait in line at an Apple Store unless you just want to).
Pricing, as expected is, $129 for a single user license, and $199 for a family pack. The minimum system requirements for Leopard are a minimum of 512MB of RAM and an Intel, PowerPC G5 or G4 (867 Mhz or faster) processor.
