This Unreal 2.2.4 beta 1 update should fix any bugs that might be in your version of Unreal Mac, but please read the install instructions in the readme file carefully. This version fixes the problem in 2.2.0 in which users who had performed a partial install of Unreal (with maps kept on the CD) didn't see any maps listed in the Deathmatch/BotMatch menus. A bunch of network administrator bugs have been fixed as well. To view all the fixes and enhancements, click here. Remember, this is a beta update. If it makes your gameplay worse, go back to your original version of Unreal.
