Once installed, if the behavior is the same, please check the OS X System Preferences -> Extensions tab and make sure odrive is listed as a Finder extension and it is enabled. If it is, please try toggling it off and on to see if the behavior changes.
Hi Stephen,
Can you clarify which things are missing?
For the sidebar icon you can drag the odrive folder over to the sidebar to add it there, if it is missing.
Are you also missing the right-click options on odrive files and folders, or is it something else?
What about the sync icons indicating synced/transferring items? Do you see those?
Can you post a screenshot with some annotations for what is missing. I just want to make sure I understand completely.
