I’ve been using TF in Mojave for a month or so (waiting this long to update, fearing issues). Suddenly, it’s stopped working. The app’s icon appears in the menu bar (it’s included in system startup apps), but the visor no longer functions.
Checked the app’s pref’s and sure enough, all is set as it should be. SIP has been disabled all along, so nothing new there. Even tried uninstalling then reinstalling TF (using the TF uninstaller), but no joy.
