Hi everyone. I'm new to the forum and have recently bought a new Macbook Pro Retina, which I think is brilliant. However, I do have one question. I currently use Canon DPP on my Windows and Mac computers, with Gimp for final processing. I was thinking of getting Aperture 3, but was wondering. If I bought 3 now, when version 4 became available, probably later this year. Would Apple give a free update? Alan.
