Mac Demo update 3D problems

I noticed this evening that an update had appeared for the Mac version of the demo, brilliant I thought. I have waited calmly and quietly while lots of other people have been spewing flames over the Mac version of the game, but I trust SI to get it right and I really wanted to see the 3d pitch in action (I've only been waiting 15 years) on my Mac Mini before I buy.

I downloaded it and installed it fine, only to find for the first time ever I feel thoroughly disappointed in SI. Every time I try to watch a match in 3d the whole of Leopard freezes (yes it's fully up to date) leaving just the mouse working.

I have played every single version of CM and FM since I borrowed an Amiga in 1993 and this is the first time I feel let down. Alright my Mini isn't a 3D-killer but it's specs aren't so bad.

Model Name: Mac mini

Model Identifier: Macmini2,1

Processor Name: Intel Core 2 Duo

Processor Speed: 2 GHz

Number Of Processors: 1

Total Number Of Cores: 2

L2 Cache: 4 MB

Memory: 2 GB

Chipset Model: GMA 950

What's going wrong, please sort it SI.

I guess it's the GMA 950 graphic chip that causes the problem. Other users (pc and mac) did have problems with 3-D and the Intel graphic chip.
