Smith Micro has announced CheckIt 2, a new program meant to optimize a Mac's performance. The title combines five utilities into a single package, including TechTool Platinum, Spring Cleaning, EMC Retrospect Express, Executive Sync and StuffIt Standard. Users can diagnose and fix hard drive issues, manage file clutter, backup content and compress files to save space. Functions unrelated to performance include file encryption and synchronization.

TechTool Platinum is designed to fix hardware problems, and creates a bootable DVD to diagnose and repair damages. Spring Cleaning helps to reduce hard drive clutter while protecting data and online privacy; it can also be used to manage files and directly boost performance. EMC Retrospect Express is used to backup critical files and restore lost data, with support for automatic scheduling. Executive Sync allows file sync, and StuffIt Standard offers over 30 different compression formats.

CheckIt 2 is compatible with Mac OS X 10.4.11 or higher, and can be bought for $100. Some features of Spring Cleaning require Mac OS X 10.5.
