640 x 480 resolution in main screen

[itsobo]

When the computer prompts to change resolution from within the main screen/chat screen, it only gives two options of the same: 640 x 480 at 0 Mhz.

I run a Mac OS X 10.2.8

I would simply recommend not changing the resolution and let Myth run in a window, except for when playing an actual game. Just make sure window mode is unchecked on the screen prefs screen and OpenGL is selected for your renderer.
