Today’s software promo on MacUpdate features Mac Cleanse 1.0.1, which is available for US$9.95 (50% off retail $19.95). “Mac Cleanse securely scans your system for activity and erases the desired information. Whether you’ve been gift shopping online, discussing confidential business matters, visiting inappropriate web sites, or just want to clean out your system, Mac Cleanse is your savior. Unlike some other privacy protection tools which go through your system with brute force, Mac Cleanse has been thoroughly tested and only removes the necessary files, and reports all errors.” Mac Cleanse requires Mac OS X 10.3 or later.
