If your Mac is running an older version of macOS, and doesn’t support the current version of TechTool Pro, we can find the right version for your Mac.
First, contact our tech support staff by emailing firstname.lastname@example.org with the following information:
1) Your model of computer (i.e. MacBook, iMac, Mac mini, etch)
2) Your Mac’s processor (i.e. Intel Core i7 3.0 GHz)
3) Amount of RAM installed (i.e. 8 GB)
4) Version of macOS installed on your Mac
Our tech support staff will provide you with the information on the appropriate version of TechTool Pro that will work with your older Mac and how to obtain a copy of that older version.
