I've had to buy an older Intel Core Duo Macbook to replace a stolen one. I've installed Aperture 2.1 from an old disc. It won't open, I get a message saying something like: "You can't use this version of Aperture with this version of Mac OS X. You have Aperture 2.1." I'm running 10.6.8.
I rang Apple, the reply was 'it won't run on your machine, there's nothing you can do. But I can make it work for you it will cost £35.' I declined that offer. I have an Imac running Snow Leopard with Aperture 2.1 running OK.
I've tried to install Rosetta (to see if that would open Aperture)from my Snow Leopard install disc. I get a message telling me the installation was successful, but I can't find it anywhere on my hard drive. Any ideas?
