Bartender 3 (version 3.0.8 as of 1 October) is available as a free upgrade from version 2. The new Bartender menu is a stroke of genius – instead of expanding to show all menu bar items or to show the hidden ones below the menu bar, it now toggles between visible and hidden items. Version 3 even properly hides the AirServer icon, which version 2 could never do. A half star off because sometimes a few icons end up in the wrong spot.
This has only worked half-assed on Sierra. And the dev. is another deadbeat who doesn't respond to messages.
WTF do they have a "contact us" page if they aren't going to respond?! Should call it a "DON'T contact us" page. https://www.macbartender.com/contact-us/
After every reboot some icons move to the left side of the menu extras. And the eject button can no longer be hidden.
