After weeks of frustration I disabled SIP, to get TotalFinder back in the game. I couldn’t be without my double tap on Option to instantly get a (double) Finder Window. And to have folders on top.
But! After I disabled SIP my Logitech Unifying Mouse (Performance MX) is not working properly. I can’t use or configure any of the extra buttons. Same thing with my Logitech S 530 Mac keyboard (which is not Unifying though). My Canon scanner software (MP Navigator EX) crashes at start. Anyone who experienced similar problems? Is it because I disabled SIP or may there be another explanation?
