- Computer 1 (which experiences the problem): iMac, OS X 10.8.4, Aperture 3.4.5, ZEVO ZFS driver
- Computer 2 (which does not experience the problem): MacBook Air, used to have OS X 10.8.4 installed, Aperture 3.4.5, ZEVO ZFS driver
- Aperture Library on an external, locally mounted drive that is attached to whatever computer I work on with Aperture at the time, the drive is formatted with the ZFS file system using a third party ZFS driver (ZEVO by GreenBytes, Inc.)
my Aperture library is on an external drive formated with the ZFS file system. Recently, what happened, if I attach that drive to my iMac, and import photos, there are no previews built for them, all I see is the thumbnails being blown up to full size, and the pictures are thus extremely blocky. However, previews generated on another computer, or before, show up just fine.
If I attach the same drive to my MacBook Air, it updates the previews just fine. I tried copying over the preference file from the MBA to the iMac, but no change in behavior.
This issue is relatively new, because going back and forth between the two computers was never an issue, so it could be related to the latest Aperture 3.4.5 update.
Unfortunately, the MBA is no longer available to test and troubleshoot this issue for reasons that Apple prohibits me from mentioning here. Some drivers don't like to surf.
So at this point the only computer I can access my pictures on is the iMac, and that's the machine that doesn't process previews!
E.g. when I select eg. a 1000 freshly imported 24MP raw images and use the generate previews command on them, I can see in the Activity window that Aperture "processes" all these images within a few seconds, which of course is impossible, and accordingly are the results: same blocky images, which are just scaled-up thumbnail images.
So for whatever reason, the iMac refuses to process the pictures. Anyone had a similar issue? Anyone having an idea as to what might cause this? The puzzling thing is, that the same library works/worked just fine on another computer...
