Thanks for the reply Jono,
The interface is very slow,e.g. like dragging on the timeline is slow, more tabs more slow, strangely it is faster on lubuntu via vmware (of course not as fast as the lubuntu i installed normally on HD), i really dont get it??
and actually it happen on other 3d software, i tried installed houdini apprentice, the interface is slow too (and yeah, its normal in lubuntu version), but why the games i installed are fast (e.g. doom 3),
I think the problem is the OS (I have Mountain Lion installed), come on Apple… really… its very stupid problem,
its a good machine, what a waste…
Anyway, i will stay with Lubuntu for Blender, and use Mac Osx for music project or playing games…
