Hi Albert,
I happen to have a MacBook Pro for a few days that I'm setting up for a friend, so just tried copy/paste and all works fine for me in 9 ... from project preview and notes and elsewhere.
Just to confirm your AC 9 setup: there is no way to upgrade to 9 build 2219 directly on a MacIntel. One must copy the entire ArchiCAD 9 folder from an upgraded PPC Mac into the Applications folder on the MacBook Pro. Having done that, all works perfectly for me, although a little slow because it is emulated/Rosetta of course.
I cannot imagine that it matters as far as the copy/paste is concerned, but I am running the updated WIBU driver that supports AC 9 and AC 10 on MacIntel:

AC 10 seems to run well, too. I had one mysterious crash, but otherwise my only complaint is our wait for the missing MacIntel add-ons such as the movieplayer that allows the interactive training guide to be used, and the Spotlight plug-in, which doesn't work:

I hear that the missing SketchUp add-on is not GS's fault, but that they are waiting on SketchUp to release an Intel-based devkit and version of Sketchup... and something similar for MaxonForm.
Regards,
Karl
