How to update 10.4.11 OS X? Is there a way to update 10.4.11 OS X to the newest version of OS X? I have Mac Pro (2 x 2 GHz Dual-Core Intel Xeon with 1 GB ram).
You'll have to at least buy Snow Leopard to upgrade. You can buy it from the Apple Store for $20, and then the upgrade from that to Mavericks is free.
