Micromat has release TechTool Pro version 4.5.

The software is a Universal binary version of the application that will run on both Intel and PowerPC-based Macs.

TechTool Pro 4.5.1 is a full-featured Macintosh diagnostic and repair program capable of running and repairing Intel and PowerPC Macs. It can optimise and defragment drives, test hardware and software systems, recover data and much more.

All the application's features are now available for Intel-based Macs as well as PowerPC models. This includes the eDrive emergency start-up partition.

Unlike most software, more than a simple re-compile of the program was required to support the new Intel-based Macs. Because TechTool Pro 4 works with the computer hardware at the lowest levels, it was necessary for Micromat to completely re-engineer the software from the ground up.

TechTool Pro 4.5.1 ships on DVD, which will automatically boot the correct system version. Due to the sheer size of the application and system files, a downloadable update from earlier versions isn't available. However, a DVD update will be made available to TechTool Pro 4 users for $25.

TechTool Pro 4.5.1 will begin shipping in early July 2006.
