Since you keep sending me mails about the new release of TTP 11, I'm thinking if it is any use for me.

I'm still on el captain and don't want to update my IMac, although it can be done the new OS updates are made for new models with new hardrive and will stop many software to work.

Also the problem with TTP now without a DVD, you have to get the OS on an external drive that can be damaged etc... (so can 't be optimised to work without any fault)

My question, If I update TPP9 to TTP11 (as I always buy the updates it cost less) will it work on OS 10.11?

Back then the DVDs must be used with the right version of the OS as I noticed higher TTP ones may don't work.

Another question I have is still related, I have bought a USB 32G key to eventually install High Sierra and so the TTP 11 on it. I never tried to restart from the key (to use as installed on the computer) and not sure it won't affect my Imac drive . I would need another ext drive or partitioned to have another High Sierra with ttp11 to clean up the external USB and the TTP9 that can't be optimized from itself.
That makes a lot of spending just to use your software that is not 100% sure to get the drives out of troubles.
Enlighten me to help me understand the reason of getting another ttp version.

Tech Tool Pro 11 supports OS X 10.10 through 10.14.

You can use the installation of TechTool Pro 11 on your internal hard drive to examine and repair the 32GB USB key, and vice versa (once TechTool Pro 11 is installed on the USB key). Since the USB key has solid state memory, you should not attempt to optimize the files on it. The wear leveling feature of the USB key puts file pieces in places that even out the wear on the USB key's memory cells.

I suggest you change your screen name to something other than an email address. These forums are indexed by Google, and you might get a lot of spam. Use the My Account link at the top of the page, and then the Account Information link. Changing your screen name retroactively updates the screen name that appears in all of your postings.
