OSX Lion and TS3 - Patch released, fixes graphics issue, causes problems with Town Life, GURUS?

What annoys me is the fact that the graphics card problem was made aware all three companies involved yet not one did anything about it. I just hope one of them fixes it because I want to be able to play Sims Pets when it comes out. I dont see why the older Macs are supported yet the newer ones aren't. surely it should be the other way round?
