I am trying to install TotalFinder on my MacBook Pro (15-inch, 2017), 10.13.3 and is just impossible. I never get the pop-up window to install the system component. I have already tried 10 times enabling and disabling SIP but it doesn’t work. TotalFinder still works with SIP disabled, but I want to enable it!
I followed correctly all steps, since I also installed TotalFinder on my MacBook Air and it worked. What can I do? How can I force my computer to install the component?
