Apple has released Aperture 3.2.4, which promises improved stability for the professional photo organizer and editor when running on Mac OS X 10.6 Snow Leopard. The only other item noted for this maintenance release is a fix for an issue that prevented the Viewer from updating correctly after editing a photo using an external editor.

Set Password Activation Time in Snow Leopard
In Snow Leopard, you can now set an amount of time after your Mac goes to sleep or engages the screen saver before it requires a password to log back on. In Leopard, the option was simply to require the password or not. Choose among several increments, between 5 seconds and 4 hours, from System Preferences > Security.
