I am using LR 5 on a MAC, I uninstalled the complete collection of Nik Software, however, when i reopened LR, and select a photo, go to photo, select edit-in, Nik software modules still appear there. How do i get rid of them?
Please go to the preferences of the Lightroom choose the "External Editing tab".
Click on clear under "Additional External editor"
