I am running P6 on a dual 1.4 G4 without problems - the same holds for a Mac Mini and my Titanium (and I also have renders made on these in my gallery).
Its working fine, I see all dialog boxes etc, and up to now P6 never crashed.
The only problem I encountered is that in some circumstances copy and paste are not possible - for instance copy light parameters and paste it onto another one.

The most obvious thing for me is that permissions are not set right if does not run - it could happen, that the app has not write permission for the directories where it tries to put its temp files - this might be the case when you installed the app as a single user app and not as admin or root.

Also get the newest security update - one of them in between caused many problems because it was full of bugs - this is fixed and repaired with the latest security update.

Forgot one thing: I installed the video drivers directly from the Radeon website - in ten four are buggy drivers, coming with one of the security updates.
