Aladdin Systems has released Spring Cleaning 4.0 for Mac OS X.

The Macintosh uninstaller removes hard-drive clutter - maximising disk-space and increasing a Mac's performance.

Features new to this version include: MailCleaner, which locates hidden email attachments; and CookieEditor, which removes unwanted cookies.

This version has two features for Mac OS X, QuickCompare and AccessMonitor. QuickCompare identifies differences in duplicates, while AccessMonitor keeps a track of the times Mac OS X files are opened. There are two cleaning modes, Standard, which guides users through the product, and Advanced for specialized cleaning.

Spring Cleaning 4.0 costs $29.95. Aladdin is offering a 30-day, money-back guarantee that expires on August 15. UK pricing is unavailable.
