You can normally find corrupt preferences files on your Mac by using the "plutil" command line tool in your Mac's Terminal. However, understandably some of you might not feel that comfortable mucking around with the Terminal. Thankfully, Preferential Treatment makes this tool accessible to anyone by offering it in a straightforward interface.
Browsing for corrupt preferences files is very easy. We liked how the application parsed results, revealing the location and the specific problem for each file. Once you've found suspect files the best solution is to trash them, which you can do straight from Preferential Treatment's interface. Just to be on the safe side, we also suggest uninstalling the related applications and re-installing a fresh copy. You should also save a report of your scan, once again via Preferential Treatment.
Although Preferential Treatment lacks readme files, it's a great application to have, which makes finding corrupted preference files accessible to anyone.
