MonitorControl: Magic Keyboard 2 brightness keys (F1/F2) no longer control external monitors, only MacBook pro display

For a few weeks after initial install, the Magic Keyboard 2 brightness keys (F1/F2) controlled the external monitors – which is what I want.

Now said keys only control the native, MacBook Pro display. (I’m running macOS 10.14.6.)

I’ve uninstalled and re-installed, both as a .dmg and a homebrew cask. I’ve removed the ~/Library/Preferences file. I’ve pressed the “reset the preferencess” (button) multiple times. I still can not get the app to do what it did (again, for a few weeks, maybe a month or two) upon initial install.

Thoughts? Need more data from my system?

I’m happy to wipe out all my MonitorControl.app software and related files and try again.

This may or may not be fixed in #237, I’m not sure but we’ll find out soon enough… You could also already test the PR if you know how to and find out faster 🙂

@JoniVR - thanks much, my team really appreciates this project, and your diligenceto upkeep it.

Short version: I have not been experiencing significant issues prior to v2.1.0, but I’ve installed it (v2.1.0) nonetheless and try to remember to report back any anomalies.

Details

Since a previous version was working okay with the restart workaround I may not noticing anything different.

I also will try to remember to post here If I find I no longer have to restart MonitorControl, although said problem/workaround typically is not needed unless I reboot macOS (…if I recall correctly, and I’m not sure that I do).

Hi, I have just started using MonitorControl on my late 2011 macbook pro. I was running into the same issue where the keyboard controls for both volume and brightness did not work for the external display until I moved the menubar to the second display. My system details are the following:

Late 2011 Macbook Pro, 15 inch
AMD Radeon HD 6770M 1024 MB (in use)
Intel HD Graphics 3000 512 MB (not in use)
Monoprice V3L6W 35-Inch Display over minidisplayport to displayport adapter & cable
MonitorControl version 2.0, build 640, installed via homebrew
MacOS High Sierra version 10.13.6 (17G13035)
I am piping sound from my Mac through the displayport connection to some external speakers

As noted, the volume and brightness controls did not work until I moved the menubar to the external display. I do note that the volume control is very nonlinear at the moment, but that may be how the external display handles the input rather than MonitorControl.

I hope this information is helpful.

Mark
