Usage note: if you use Bartender, you can move Keyboard Maestro’s icon into Bartender’s menu and cause Bartender to display the icon in the Apple menu bar only when a macro is active by using these settings – the duration setting can be longer if desired.
Here is a short video of Bartender. There you can see how to open KM Apps
I use “nothing” option, and display KM icon right after the Bartender one. Just to save 1 click, cause I keep important but rather rarely used macros there (not to remember hotkeys), in the status menu. Like: shorten URL using goo.gl, changing spctl status (for installing third party apps), Bluetooth restart, Converting video for car system and so on
And even Maestro Engine restart. I noticed lately a choppy scrolling on Sierra. Tried everything - nothing, but logout/login. Then fortunately tried to restart Engine and boom - all returned to normal ))
