Hi there,
I bought a 2.4ghz black macbook about 2 weeks ago. Everything is awesome except sketchup. I have been trawling through all the forums trying to figure this out. Seems that turning off fast feedback does help somewhat, but after working with a model for a few minutes with lots of middle-button panning and orbiting it starts to slow down. I have problems box-selecting too. If I disable hardware acceleration I still have slow, odd behaviour. I have also tried installing the ThawUp patch to no avail. http://www.sketchucation.com/forums/scf/viewtopic.php?f=11&t=2753&p=12822&hilit=thawup
The funny thing is- I dual boot Windows XP with Boot Camp on this machine and I can run Sketchup under Windows and it is really fast! So it's obviously not the machine itself.
One thing I did figure out was that my logitech mouse had a feature where you can tip the scroll-wheel left or right which was making matters worse in sketchup - so I recommend you try disabling that if you are wondering why the middle button orbit is acting funny.
If anyone has any new information on this please let me know! I want to use my mac as a mac not as a PC.
Thanks,
C
