KM Editor crashes on High Sierra beta 7


It’s all in the title: just installed High Sierra beta 7 and my KM macros work just fine with the exception of one due to a menu change in QuickTime. Tried to open KM Editor to fix the macro but the editor keeps crashing during launch.

I know I’m talking here about a problem related to an unreleased version of macOS so that is to be expected and I have only myself to blame if I face that sort of problems. Fair enough.

So that’s why I’m posting here, just to ask around seeing if I am the only one facing this issue (in which case I need to possibly investigate further).

And if I’m not the only one, is there a beta somewhere I could try (or apply to participate)?


Same problem here. Macros continue to work fine, but the editor crashes in HS.

The only crash I have seen with Keyboard Maestro in High Sierra is caused be broken Color Pickers.

You can launch Keyboard Maestro editor with the Shift key down which I believe stops the Color Pickers from loading. Search your system for old color pickers and remove them.

Known problematic ones include:

  • RCWebColorPicker
  • WebPicker (might be the same as RCWebColorPicker).

If you find others that are incompatible, please add them to this topic.

Nice one, that was the reason indeed. Removed the few custom pickers I had installed along the years and KM doesn’t crash anymore.

Thanks! :+1:

Worth noting that launching KM Editor with the Shift Key down didn’t make any difference though.

I agree that launching KM Editor with the Shift Key down didn’t make any difference.

RCWebColorPicker was the culprit. Thanks, Peter.

SkalaColor.colorPicker here. After moving it out it started.

For me, it was ZeplinColorPicker.colorPicker. Solution, as above, worked perfectly (save for the shift-key thing; that didn’t work).

These colorpickers also crashed KM Editor for me in High Sierra:

  • CBShadesColorPicker.colorPicker
  • DeveloperColorPicker.colorPicker
  • HexColorPicker.colorPicker
