Unreal Tournament 2004 and Mac OS X 10.10.3 Game Crash

For my fellow Unreal Tournament 2004 fans on the Mac, today's update to OS X 10.10.3 seems to have killed startup for the game. The boot up begins and then your mouse cursor appears before the screen fades back to the desktop; the start up crashing before the game's 3D CG logo appears.

The game now fails on all of my Macs running OS X 10.10.3. It's funny that this one update kills it. So it makes you wonder what was done. Graphics engine update? Etc.?

I'll be on the lookout for a solution, so I'm putting this up here just in case anyone else has the problem or has a solution already.

Thanks!
