Apple issued an update to Aperture late Friday, its pro-level photo-management and editing software. Version 3.4.1 is a bug-fix release, primarily addressing an installer issue in v3.4 that caused the application to quit on launch for some users due to accidentally corrupted preferences. The new version also improves the reliability of syncing photos to iOS devices via iTunes, cleans up a bug with downloading and viewing photos synced with Facebook albums, and generally improves overall stability.
