Hey,
The Platinum Team tries to continue to support Marble Blast Platinum for as many users as possible. Recently, we had to drop Mac OS X 10.6 support because of compiling issues with the newer code. However, those issues have now been resolved, and we have decided to add Mac OS X 10.6 support back into Marble Blast Platinum 1.50. The game client has been tested on an iMac running OS X 10.6.8 (the latest patch to Snow Leopard). This has no affect on Windows users in any way. For those of you who had to update your Mac client to play the game, I am sorry that this patch did not come sooner. I wasn't sure if this was going to compile for Mac OS X 10.6, but it ended up working in the long run. Sorry to keep you all waiting.
Looking into the future, I might try to add Intel Mac OS X 10.5.8 support if time permits, as well as a possibility of a PowerPC version. No guarantees; however, quite a bit of code would have to be rewritten as there are some dependencies on the Snow Leopard version of Mac OS X.
To all OS X 10.6 users, have fun with Marble Blast Platinum 1.50 and enjoy it!
