Is this software obsolete? There is no download. Both links go to an Apple page to initiate troubleshooting, but no option to download this software is provided there.

The link is working fine, it took me about 30 seconds to download the software just now.

MacUpdate lists current TechTool Deluxe version as 3.3 (released 11/3/09). Developer's web site shows current version as 3.1.3 (released 9/3/09 for Snow Leopard compatibility). MacUpdate download link yields TTD 3.1.3. This appears to be an error on the MacUpdate page (or else the TTD 3.3 release was pulled for some reason & version number was not reverted back).

Note to MacUpdate: upon further review, the TTD updater is version 3.3 but the TTD application is actually version 3.1.3. You may wish to fix this. Thanks.

What are the differences between TechTool Deluxe and TechTool Pro?

They rip you off for more $$$ Dollars $$$ ... I am a living example.

Diskwarrior & DriveGenius is way to go ...

I also no longer see any value in using this tool when Disk Utility and Disk Warrior really do all that is needed. I also find the circa 1996 Norton Utilities-like GUI rather cloying.

I've long abandoned TechTool in favor of Apple's own solutions (built into the system) or DiskWarrior. Marketing hype aside, I just don't see any real value in TechTool.

Is anyone actually able to install this update? I've tried downloading the disk image twice from the site and it says it failed to mount because it's "not recognized."

For me, this application is too flakey and does too little with uncertain results to even consider using it.

Finally was able to connect to Micromat's FTP server, BUT...

... I'm on a 6+ Mbps broadband connection, and the file is downloading at only 10kB/sec - that's dial-up speeds.

C'mon Micromat, this isn't 1997 - can you at least have a mirror for your files. Sheesh!

Whew! I thought it was just me. I got about 6-10K on two different broadband connections. FWIW, I had just downloaded an update of about the same size from another developer over the same wifi network. That one downloaded at 384K.

Update to 3.1.2 succeeded, apparently, but it just hangs on "Scanning Volumes..." and never gets anywhere.

Quality stuff, Micromat. Does Apple actually pay you to include this half-baked utility with AppleCare?

Does not install properly.

I have Tech Tool 3.1.1 installed, and ran the "updater", yet it claims 3.1.2 is installed.

when I click on Tech Tools, it still claims not to work with Leopard & shows 3.1.1

Yet, this same version, when asked to "check updates" claims it is 3.1.2.

At least you could download for whatever good it did. I can't even download. Either get an error or timeout on my connection to Micromat. Micromat needs to find some people who know what they are doing. Maybe Apple needs to latch on to someone else.

The download took a while, since everyone was trying to grab the update.

I did get it installed.

For Me. I had to uninstall, re-install 3.11 from the cd/dvd, then re-run the updater, and then it finally worked.
