I guess one solution is to work with referenced images only, and then inside Aperture change the reference for RAW files to a folder on the old machine when I come home.
So then I will see what Aperture 3.3 has to offer.
I usually do most of my work on my MacBook Pro. So I guess my back up of the RAW pictures can still be done from my old machine and then I keep my updated Aperture Library on my MacBook.
I better delete Aperture from the old machine since working in Aperture there is now longer an option with the incompatibilities for Aperture between Snow Leopard and Lion.
I am just now in the process of evaluating my back up strategy, and the choice of software for handling RAW-files is part of that rethinking. But I guess a total conversion to referenced images is not a bad idea after all.
So it is may be too early to tell if Aperture is part of that strategy. I guess it is wise to harvest some experience with the new version before I make a decision.
The fact that Snow Leopard is no longer compatible with the new version was something I probably must get accustomed to.
So now I am wondering if importing an Aperture 3.2.4 library into Aperture 3.3 will cause any problems.
Since now I will have to import my library from my old I-Mac (Intel Core Duo) to my newer MacBook Pro to consolidate the two libraries.
I realize that Apple's decision is that Snow Leopard is no longer compatible with Aperture.
