In the latest TotalFinder 1.11.8, the tab behaviour has changed. I want to use the TotalFinder tabs all the time and never use the native finder feature. But in the 1.11.8, opening a tab by CMD+Double Click on a folder or right click on a folder and choosing “Open in New Tab” will result in the tab to be opened in the native finder tab which does not serve the purpose.
OK, I downgraded to older versions. In 1.11.4, 1.11.3 and 1.11.2 the problem existed, but I never had the problem before. It only means that there is a change with Mojave 10.14.3. I strongly suspect that Apple changed something in MacOS or Finder code that caused this.
I even tried TotalFinder 1.10.10 but it didn’t run on my Mojave !!!
I’m sorry I’m still waiting for more people to experience this issue. I need to somehow reproduce it on my machine. Until then it is just shooting in the dark. I’ve tried to troubleshoot it with @posburn but we didn’t resolve it or find a way how to reproduce it on my machine.
