Hi all I didn’t realise NSLog did anything in renderOutput! It doesn’t for me - I am building for debug and can either leave the plugin app running or close it down but no logging appears. All the plugins I have created start from the Xcode template (which uses the brightness example) so they register themselves (apart from the pluginkit -a <path> thing). I have always debugged them using the "build - run - did that make a difference - build - run - did that make a difference" cycle. Hideous. Is there something I need to do to turn NSLog on? Sorry, years and years of VS and C++, only just got started on Xcode7 and Objective-C. TIA Jeremy _______________________________________________ Do not post admin requests to the list.
