I have onyx which cannot be used by Mojave, there is no update. I also have tinker tool (6.2) which has to be updated but when I tried that, it said the update is incompatible even though the download said it was for Mojave.
As for permissions, apple has a new procedure which I won't bother with. I did read that Clean my Drive 2 also repairs permissions? When I opened it, I couldn't see anything happening,
BTW, if I tap the top of my computer, the microphone is activated all the way across but when I speak, it only activates the first (2) bars but if I shout, it goes half way across. At least it is working albeit slightly.
Is there a way to improve the response.
