If options are missing in the graphical user interface restart he Mac. And if that does not fix it trash the preferences files.
A common reason for buttons being unresponsive are corrupted preferences files.
- Quit Aperture if it is running.
- Then open your User Library and remove the complete folder ~/Library/Containers/com.apple.Aperture/
- and the file ~/Library/Preferences/com.apple.Aperture.plist
Your user library may still be hidden.To reveal the hidden User Library:
- Bring the Finder forward by clicking on the Desktop or the Finder icon in the Dock.
- Select your user/home folder (with the house icon in the Finder sidebar)
- With that Finder window as the front window, press the key combination ⌘J to bring up the View options.
- In the View options panel enable ’Show Library Folder’. That will make your user library folder visible in your Home folder.
- Open your Home folder, then the Library folder, then Containers.
- Move the complete folder ~/Library/Containers/com.apple.Aperture to your desktop. Move the entire folder, not just the contents.
- Remove ~/Library/Preferences/com.apple.Aperture.plist as well.
Now restart the Mac, launch Aperture and try again to import. If all is well, delete the folder from the Desktop.
