Is anyone using Aperture on a non Intel Mac? I downloaded a trial to use on a PowerMac G5/1.6 GHz/3GB RAM/300 GB drive. The application is painfully slow/rendering is slow. I did get one photo nicely edited, but it had already been edited in Photoshop, got some improvement in sharpness with Aperture. Tried an unedited RAW photo and just gave up. I am wondering if my older Mac cannot handle this program. If it runs well for other on Intel Macs, I will consider it when I upgrade in the fall.
