Thanks. I bought DriveDx through the App Store and the receipt from 2016 is still in my iCloud account along with everything else I've ever downloaded from the App Store. However, that receipt contains no key code, and I can't find an email that does either. I recycled my old Mac last year and reinstalled the earlier version of DriveDx last year as well. It worked before I upgraded to MacOS Ventura. However, the license file you've told me to find is not in the folder at the end of the path name you sent. Any other suggestions?Do you still have your purchase email with the license key?
Alternatively, copy the file ~/Library/Application Support/DriveDx/DriveDx.driveDxLicense from old to new Mac. Restart DriveDX (maybe reboot).
