Hey, my minecraft is not starting. I click play offline, it shows the Mojang sign and then it goes to a dirt screen and then the crash report comes in: ---- Minecraft Crash Report ----
// I bet Cylons wouldn't have this problem.

do what he said Visro

Bulldogg65's issue is that he's running Mac OSX 10.5 The current 1.5 build makes this OS version incompatible due to an OpenGL issue. It might be fixed in the snapshot for 1.5 so I would recommend trying that. See details on the forum homepage.

Vizro is not running Mac so looks to be just a graphic driver issue. Vizro you should try to get an updated driver for your graphics card. Try your PC manufacturer first, unless you installed the graphics card yourself, if so then go to the graphics card manufacturer and download a driver directly from them. If you're not sure what you have post a DXdiag report here and we can help further.
