Samuel Errett Posted May 14, 2018 Share Posted May 14, 2018 I finished my High Serria hackintosh about a week ago. The only problem is brightness control doesn’t work. The slider shows up in settings but it does nothing changes when I move it. It’s not the end of the world but its an inconvenience to reboot the laptop and reset the brightness through the bios, and since I'm using this computer in school and constantly moving around to places with different brightness levels this would defiantly be a great feature to obtain. Thanks for the help. Quote Link to comment Share on other sites More sharing options...
Administrators Hervé Posted May 14, 2018 Administrators Share Posted May 14, 2018 There is no brightness control for this old system under OS X. You can only apply BIOS controlled brightness adjustments through Fn-UP/Fn-DOWN keys. That's the end of it. I would remove whatever change you applied to get the (non-functioning) slider bar in the Display PrefPane. BIOS levels do not get reset on my D630 laptops; make sure you've either applied the AppleRTC patch through Clover or installed a pre-patched kext.
