haha no not on a Mac ,I used the TSM for a couple of models and had problems as I now know becuase of my modeling ,the horsewoman I done worked really well though .I started using the 2008 rig when Mark was making it and I realy like how it work's plus Iv got used to installing it now,probably not perfectly but prety good and it has a lot of things going for it .fans are allready there ,hands work very well and other things like spine controls make it a good rig for me .If youv not triede it you should at least take a look at it Rob .There are a few good rigs now TSM,Lightrig ,2008 rig and if your more advanced than me and thats most ppl the squatch rig .One thing I find beyond me is a face rig so I use poses .I have no dislikes with any of the rigs its just that I find this is good and I can actually do it
