I just updated Apple Aperture to version 3.4. Opening an existing 3.3 library caused it to update successfully to version 3.4 — but it would not open! Each time it would cause Aperture to crash. The fix? Delete Aperture’s preference file; there was no need to reinstall the Aperture software application.

Here’s how to locate and delete the Aperture preference file:

1. In the Finder, select the Go menu — then hold down the Option key. You’ll see the normally hidden user Library. Select it.

2. Now open the Preferences folder. Locate the com.apple.Aperture.plist file and toss it in the Trash.

3. Reopen Aperture. That should fix the problem.

Holding down the Option key will reveal
the normally hidden user Library.
