The exact steps I am taking are:
1. Start Aperture...wait till it loads and then connect USB to Nikon D300... Go to import...name project or image info.
2. Click Import all Selected and then Aperture comes up with Crash notification.
3. Send Error Report to Apple.
4. I have tried Belkin Card Reader...does the same.
5. I have used this Camera multiple times...and also a Nkon D7000 without any issues.
6. Both Cameras use Sandisk Extreme Pro Memory Cards...one uses Compact Flash and the other uses twin SD Cards.
7. I installed Nik Softwares HDR Effects...haven't been able to run it successfully as yet.
8. Nik Software support sent me details on Duplicate Arial Fonts...removed them as well.
9. I am running a NEW model iMac with i7 3.4Ghz with 16GB Memory with 256GB SSD... With a 2TB Internal Secondary Drive as well.Running OSX Lion 10.7 and I constantly check for and do all Updates as notified......is absolutely Frustrating.....just need to find a Solution.
