Hey everyone! If you're on 10.6 (Snow Leopard), hit the "Software Update..." function and upgrade to 10.6.3.
Most notably, Apple updated graphic drivers. There isn't much information about what was changed exactly with graphic drivers, but it shouldn't hurt anything and may or may not improve performance. Like to know how this update performs with all the different Macs out there.
You can read the list of changes that the update does. Like updated time zone handling for Antarctica.
