I was facing an issue today: the old G4 Mac that I own has Photoshop on it. The new mac I use – an intel macbook pro cannot install the PPC version of Photoshop that I own. The old G4 died last week, so no using PS. I downloaded Photoshop Elements to demo it and get one image converted from a large size to a small size and then do some gradient work. PS Elements refused to install with various errors. I searched Google and came across an application called Pixelmator. It’s one of the best photo editing tools I’ve used in a long time at this price point. In fact it seems to have all of the same features and tools as my old version of Photoshop CS, and it’s only $59. I’ll continue to demo it for the 30 day trial. Great app. I highly recommend it if you don’t feel like spending hundreds on the competition.
