Make sure you're using the latest TurboActivate and a the latest XCode and codesign apps.
We've had a number of customers who have had no problem signing their macOS apps with the latest version.
Some things of note: libTurboActivate.dylib is unsigned by us. Why? Because Apple no longer supports EV certs for signing binaries. Everything has to go through Apple. Which is fine and dandy, but we don't have time time to jump through a bunch of new unnecessary hoops. Not yet at least. Eventually.
Secondly, the TurboActivate.dat file is a resource file. It should not be modified. If the code signing utility you're using is complaining about it then move it to an internal directory where it will not complain about it. Or embed it directly in your app and load it from memory at runtime.
