I am running Aperture 3.4.3.
I had this version running on an Intel MacBook Pro, with its db on an external firewire drive.
I purchased a Retina MB Pro, and transferred all apps, etc. to the new laptop.
I also purchased a USB3 drive, and transferred my Aperture db from the FW drive to the new USB drive.
On my old laptop, I can open Aperture and export, modify, etc. photos from the FW drive.
On the new Retina laptop and the USB drive, I can load the db, but if I try to export or do anything, I get a warning that the original files cannot be found.
The db on both drives is idential in size and permissions.
What file or process have I missed in this updating process???
I'd try the following: Create the library on your new drive again.
Connect both drives to your new Retina Mac, the old Firewire and the new USB 3.
Then open the original Aperture library in Aperture on your new Mac,
- select all images at once and let Aperture export the images as a new Aperture Library on your USB 3 drive.
- Then try if you now can open this new exported library with Aperture from your new mac.
