Micromat today announced an update
to their top-of-the-line system diagnostic and repair software TechTool Pro, bringing the utility to Universal Binary status. As a repair technician, I use TechTool daily to repair corrupted drive volumes, detect failing disks, and stress-test hardware. Although version 4.5 of the program sports no new features aside from Intel support, Micromat is not releasing an updater for previous versions of TechTool. According to the company a large number of under-the-hood changes and tweaks to the program prevents such an update from being practical.
Current owners of the software can download a public beta of the new version, and order a DVD update for $25 which will ship in July. Subscribers to Mircomat's TechTool Quarterly subscription program will automatically receive the update in the mail at no charge.
