nofearl Posted March 25, 2010 Share Posted March 25, 2010 A code and plist to set brightness on startup. Mine resets 100% on every startup, so this binary (written by Nicholas Riley) sets it to 10% Change the plist to increase default brightness (between 0.1 - 1) copy brightness to /bin (edit and) copy plist file to /System/Library/LaunchAgents/ run sudo chmod +x /bin/brightness chown root:wheel /System/Library/LaunchAgents/com.nofearl.brightness.plist Brightness.zip 1 Link to comment Share on other sites More sharing options...
Ludwig Bartholomew Posted December 29, 2010 Share Posted December 29, 2010 Thank you so much I couldn't find a way that works, but this does. Link to comment Share on other sites More sharing options...
MiniHack Posted December 31, 2010 Share Posted December 31, 2010 Thanks this little method works well to set the brightness level to a fixed value at startup. What would be nice though is to modify the code to read the brightness after each brightness change and feed that brightness level into the startup plist - that way you could have a nice way of the display remembering your last setting at next startup.... Any ideas for a nice way to achieve that? Link to comment Share on other sites More sharing options...
NIXin Posted January 30, 2011 Share Posted January 30, 2011 Hi Great stuff! Thanks. There's a small bug. If a display doesn't support changing brightness I get an errors: brightness: failed to set brightness of display 0x3c099d81 (error -536870201) So if I have many displays connected it will of course change the brightness for the supported screen, but also display this error. EDIT: sorry guys, I didn't know we can set the brightness for only one screen! Link to comment Share on other sites More sharing options...
moonislune Posted February 5, 2012 Share Posted February 5, 2012 Sorry to revive an old thread but this works great for me on 10.6.8 . I changed the value in the plist (in the zip file) to .5 and it sets brightness to 50%. Thanks again, this will help my battery life! Link to comment Share on other sites More sharing options...

GabeVitoro Posted April 15, 2014 Share Posted April 15, 2014 Hello, This is not working on Mac OS X Mavericks 10.9. I copy the file to /bin/, changed to brightness in the plist to 1 (I also tried 1.0) and ran the command with and without sue before the second line with the chown command. When I restart, nothing happens. :-( If anyone has an updated method, I'd be happy to hear it. I want full brightness after startup or a command UNIX or Applescript to change brightness. Thanks, Gabe Link to comment Share on other sites More sharing options...
