My MacBook Air seems ro be using a lot of battery since I installed Teamviewer. I installed Teamviewer with unattended access enabled and now note that the display never goes to sleep which accounts for the battery use. I realize I may be wrong bout the way unattended access is implemented, but it makes sense to me. I really don't need it on my MBA and have tried to find out how to turn it off. Connection:Setup Unattended Access does nothing and seems that it ought to be the place to turn it off and on. Where can I turn it off?
If you were to close TeamViewer when it wasn't being used, and also unchecked the box in preferences > general for "Start TeamViewer with System", that would take care of that. I never noticed TeamViewer using much battery, but if your machine isn't going to sleep you might want to check those settings in System Preferences > Energy Saver.
I seem to have at least partially licked the problem. I had done the things you suggested prior to posting the question. I agree with you that Teamviewer never seemed to use much power before, so I'm not sure what I did, but things are better and it may or may not have been Teamviewer—which I realie is not very helpful to others.
