Tech Tool Pro 12? This says that the latest version, Tech Tool Pro 13, is not yet compatible:
Thanks for catching the typo. I have corrected the original post.
For what it I worth, after being with TechTool pro through 12 versions, I have yet to convince myself, it offers me enough utility to be worth even the $29.95 upgrade price. I had already dropped DiskWarrior and Drive Genius for the same reason vive and three years ago respectively for the same reason and held onto TTP just in case. But there has been no just in case any one of the three utilities would have prevented or recovered from in more than five years.
For me, it's just so handy using its eDrive feature (along with Onyx). And there have been a few times where some of its features did resolve some minor issues I was having.
Given that I rarely, if ever, have issues by 1) doing a lot of disk cleanup on my own, 2) run Onyx and Tech Tool Pro every week, and 3) run SuperDuper! every week (thus keep my Macs "lean, mean, and clean"), I'll continue to use it.
