About the TechTool Pro Boot DVD

When using a diagnostic utility, it is sometimes necessary to boot your Mac from another volume in order to diagnose and repair problems on your normal startup volume.  Historically, many disk utilities have provided a DVD for this purpose, including TechTool Pro.  Since version 4, TechTool Pro has also included the eDrive tool in order to run TechTool Pro and other utilities from another bootable volume.  With the advent of Macs without DVD drives, the functionality of the eDrive is becoming increasingly important.  If you haven't already, we encourage all TechTool Pro users to create an eDrive in lieu of relying upon the DVD for their troubleshooting needs.

For those who still require the DVD, here is some additional information:

Our current bootable DVD (Version 6.0.6) supports Macintosh computers capable of running Mac OS X 10.6 or greater, except for Macs which originally shipped with Mac OS X 10.7 'Lion' or OS X 10.8 'Mountain Lion' installed:

  • MacBook Air (July 2011)
  • Mac mini (July 2011)
  • 21 Inch iMac (August 2011)
  • MacBook Pro (October 2011)
  • All 2012 Releases

* The eDrive feature of TechTool Pro will boot all Macs that support Mac OS X 10.5 or later.

The system version on our current bootable DVD is:

  • Mac OS X 10.6.7
  • Mac OS X 10.5.8 - included as a .dmg file on the DVD. 

Macs that will boot under 10.5.8, but not 10.6 may burn their own DVD. See instructions.
