Hi Eoin,
I'm thinking you're right, recognizing that silly mistakes are all too frequent an occurrence the older i get 🙂
1. I dl'd the 1.0.1 and, clicking on the install .pkg, I get a message saying "this system does not need this update." I'm running 10.4.8 on a dual 1.8 g5 w/ ATI X800XT video card 256 meg of ram and 1.2 gig of system ram.
2. Aperture is version 1.5.2
3. I have 3.7 of Adobe DNG, w/ preferences set to those you've named. I click on Convert and I get a dialogue box showing each of the PEF's "converting" to DNG's.
4. Have edited the correct file and indeed had to change permissions and ownership to do that. Reopened and file was there, and restarted Aperture after all that.
5. My thought is that it is somewhere in Step 4 here where I'm screwing up, so, when I get back from work later today, I'll give it another try.
thanks so much for patience, Eoin,
tony
