I installed TotalFinder v 1.6.17 today on my mac running OS X Yosemite version 10.10.3
At first my machnie was incredibly sluggish, with activity monitor showing my finder at anything between 103% to 184% usage. I relaunched the finder and this brought the percentage down to 55%.
However, I still do not see any of the TF features anywhere and there is no TF menu in the Finder prefernces menu.
I used to have TF running fine on Mavericks but it has never worked properly since I upgraded to Yosemite and switched to a new MacBook Retina Pro 2015 model.
Any advice re. troubleshooting would be appreciated.
