Makes my Macbook Pro Retina crash about brightnessmenulet

[RSully]

Same here. It looks like it doesn't actually crash, just the displays don't update.

[jeske]

same here... as soon as I launch it, my display locks up. The machine seems to still be runnning, because my music is still playing, but the mouse won't move and I can't do anything but hard-restart.

+1 for me (OSX 10.9.5, Hackintosh)

Same for me

[tamsky]

+1 (OSX 10.10.2, MBP11,3) I was hopeful, but same freeze of input devices. Display does not freeze as time/seconds still update in menubar.

Um, it works on DDC/CI, meant for external third party displays, not internal. Maybe it's getting confused between your laptops primary display and the external?

Laptop primary display is closed and off. Should not be active. But, maybe?

Also hangs the display on my Mac mini 2012 running OS X Yosemite 10.10.2 with a Dell via mDP. In top the process is reported as stuck and dtruss -p reports this trace for minutes at a time:

Invalid connection: com.apple.coresymbolicationd
SYSCALL(args)        = return

same here freezes the system, macbook with retina display and 2 monitors connected Dell and SAmsung

This has probably to do with the DisplayPort interface on those devices. The updated DDC implementation from https://github.com/kfix/ddcctl could resolve this issue. I got the project compiling, without the system freezing, but the brightness adjusting doesn't work either..

Hey Guys,
This awesome tweak crashes my non -retina macbook as well IF i leave my Dell Monitor connected when I open the app. If the dell is first disconnected- then the app is started and then de Dell is connected everything works fine! But thats not very apple-like...

So who could tell me how to use kfix instead? I dont really understand much of the coding / compiling stuff you are talking about. But if I try to install kfix ddcctl using the "make install" command - i get an error message with 5 different problems in it ...

Any help,coding masters ??

Same issue here too:

Same issue, 13" 2015 MBP retina.

Crashes my Macbook Pro as well (Late 2013, Retina). I have a pair of Dell U2715H displays and I believe the crashes are related to reading the current values from the monitor. I have managed to use kfix/ddcctl to set the display contrast, however, if I use this version to read the values (e.g. increase brightness with +5) I get an instant OS freeze.

Crashes on mine too.

MacBook Pro (Mid 2012) with El Capitan. I have a Dell U2713HM connected via DisplayPort.

Here's an awesome fork that does work on OS X 10.10 and 10.11: https://github.com/Kalvin126/BrightnessMenulet

@sodabrew That did the job. Thank you so much!
