4WHATITSWORTH  I purchased the Mac Update bundle. I had trouble creating a bootable DVD and was able to clear up the problem through Micramat's tech support. Apparently, one of the links downloaded the installer disk image and not the DVD disk image. Everything is working great now and I know that if I have any questions, I can count on their great tech support!

4WHATITSWORTH  A great utility for your Macintosh just got better! TechTool Pro 5 has a cool looking interface and new features such as "Trash History" which helps you recover deleted files as well as "Volume Usage", which alerts you if your volumes becomes too low on free space. The "Surface Scan", an extremely helpful tool in detecting physical defects in hard drives, can now also identify files that are located on bad blocks. Overall, I find TechTool Pro 5 to be a very informative diagnostic and repair utility.
