Hi Robert,
Intensity was always designed to run in PowerMac G5’s but unfortunately there is a technical issue with a chip that affects G5’s but not Mac Pro’s or PC’s. The relevant chip manufacturer has told us recently that they will do everything they can to help overcome the issue so we are hopeful of a resolution but obviously don’t have a timeframe or guarantee of this happening.
