Hi, I have the same problem after upgrading to El Capitan. I can no longer pop-up context menu and add folder to GoogleDrive via InSync. Insync used to work very well for me before, I share between Windows PCs & MACs (I have many due to my work), but now useless for me. How do I add a new folder now? The Insync option is still in the context menu for folders already added to InSync before the upgrade. I checked my Console and found the following regarding InSync, could it indicate anything?
