I'm using Mac Book with 2.4 Intel processor and 2 GB of RAM.
I just switch from using SWEET HOME 3D to GOOGLE SKETCHUP 7 FREE, and had the same problem of SU7 runs slow on MAC.

I think everybody has tried INIO's solution and its working well.
i tried to download the thawup installer, but it is said i am not authorized to do so.
Could you inform me, hot to get the patch?

thanks INIO
