Hello forum members. In a german hackintosh forum i found some code snippet to correct map the brightness keys for a Latitude E7440. # _OSI(WIN7) is needed for brightness keys into method label OSID code_regex _OSI\s+\(WIN7\) replaceall_matched begin LOr(_OSI(WIN7),_OSI("Darwin")) end; #syscl_fixBrightnesskey_VoodooPS2 into method label BRT6 replace_content begin If (LEqual (Arg0, One))\n {\n Notify (LCD, 0x86)\n Notify (^^LPCB.PS2K, 0x0406)\n }\n If (And (Arg0, 0x02))\n {\n Notify (LCD, 0x87)\n Notify (^^LPCB.PS2K, 0x0405)\n }\n end; How and where do i have to implement this? And, is this compatible with the VoodooPS2 kext modified by @Bronxteck

I want to disable dedicated GPU, GTX 1650 but using -wegnoegpu causes by maximum brightness to drastically get reduced. Is there a fix for this so I can disable the dGPU to maximise battery life? CLOVER.zip

The questions says it all. I have set up mojave 10.14.5 How I can enable brightness control via functions keys. Its irritating that you have to go to System Pref>Display every time to change it. Debug files are attached. debug_3170.zip

Hey all, recently been trying to get Mojave up and running on my e6230 following this guide, using this bootpack and using this DSDT file (which fixed my sleep on lid close problems). I'm happy that most everything is working so far (besides the battery indicator seeming inaccurate although I haven't had time to fully test it yet), except for one problem -- I can't change the screen brightness at all, with the option missing altogether from System Preferences > Displays. I've attached my debug report to this post, hopefully it'll help you guys out. Thanks a bunch in advance. debug_24781.zip

After I upgraded to Sierra 10.12.4 yesterday, brightness is not working anymore. Instead the brighness is at the maximum value. Changing the brightness with Fn+F3 and Fn+Insert shows apple's brightness indicator changing, however without effect. I tried installing Rehabman's latest IntelBacklight.kext on my EFI partition, without luck unfortunately. What are the steps I should take in order to fix the brightness in Sierra 10.12.4? Thanks!

Recently I've installed macOS 10.12.6 (Sierra) on my ThinkPad X201, and I could get everything working, except for the brightness. I can't make it work, I've applied a bunch of patches on DSDT and couldn't get working, so I decided to apply these patches in SSDT and... I couldn't get working as well. After a while doing some search I realize that for macOS 10.12.4 and above, the patches that I was applying doesn't work, and I would have to use the AppleBacklightInjector kext patch. I've tried the kext patch and doesn't work too. Am I doing something wrong? or my system doesn't support MacOS brightness control at all?

I am having problem with my lcd brightness value reset to full brightness on everyboot. I am running hackintosh High Sierra on a Lenovo x260. Clover is installed as UEFI only with rc scripts and using EMUVariable driver for nvram emulation. I can confirm nvram emulation is working from the nvram - p output of terminal as below. Right now, all values are retained such as volume level and other ids, except for the lcd brightness value. I am using AppleBacklightInjector kext for my lcd and patched ssdt. I am also attaching my config, kexts,ssd/dsdt in clover. Can anyone advice what should I do? fakesmc-key-BEMB-flag %01 fakesmc-key-RPlt-ch8* j130%00%00%00%00 fakesmc-key-RBr -ch8* 2016mb%00%00 EFILoginHiDPI %00%00%00%00 fakesmc-key-#KEY-ui32 %00%00%00%12 SystemAudioVolumeDB %ee fakesmc-key-BATP-flag %00 platform-uuid %cc%92%87d%d3-%b2%11%a8\%94g%ec%cf'%c0 fakesmc-key-MSTc-ui8 %00 EmuVariableUefiPresent Yes security-mode none fakesmc-key-BNum-ui8 %01 csr-active-config g%00%00%00 fakesmc-key-$Num-ui8 %01 fakesmc-key-MSFW-ui8 %01%00 fakesmc-key-MSPS-ui16 %00%03 fakesmc-key-REV -ch8* %026%0f%00%00%97 fmm-computer-name My%e2%80%99s MacBook Pro backlight-level %1c%00 bootercfg (%00 fakesmc-key-$Adr-ui32 %00%00%03%00 fakesmc-key-EPCI-ui32 %09 %f0%00 bluetoothActiveControllerInfo +%0a%87%80%00%00%00%00`%14%e4%a7%a0%0b%e1%94 fakesmc-key-MSAc-ui16 %00%00 fakesmc-key-MSLD-ui8 %00 SystemAudioVolume ? specialbootdevice %02%01%0c%00%d0A%03%0a%00%00%00%00%01%01%06%00%00%17%03%12%0a%00%01%00%00%00%00%00%04%01*%00%02%00%00%00(@%06%00%00%00%00%00%a8%f7=%09%00%00%00%00%84%8b[%c5%dd%10eA%8b%f5%ba%d1%b1%0ab%84%02%02%7f%ff%04%00 fakesmc-key-RMde-char A fakesmc-key-BBIN-ui8 %01 flagstate %00%00%00%00%00%00%00%00%00%00%00%00%00%00%00%00%00%00%00%00%00%00%00%00%00%00%00%00%00%00%00%00 fakesmc-key-MSWr-ui8 %00 CLOVER.zip

Hello Again. Back with another issue now. Have with help of the forum crew been able to install macOS Sierra on my Dell Latitude E7450 with discrete nvidia 840m And during the post installation process and to enable the FN keys to performe volume and brightness controll. I have gotten everything to work except the brightness keys What i used was All keys work except F11 and F12 for the brightness controll, how ever karambiner event logger shows the command being sent Currently it feels that the display is a little bit dark compared to the attached monitor i use as well. Anybody has any ideas on what i could do?

For what ever reason the brightness control in the System Preferences no longer works. I think it may be related to these two previous issues that I posted about in the past https://osxlatitude.com/index.php?/topic/9131-solved-e6420-monitor-sleep-turn-off-on-boot-fresh-install-of-el-capitan/ https://osxlatitude.com/index.php?/topic/9504-solved-black-screen-on-e6420-sierra-upgrade/ I am using the following DSDT because the one in Jake Lo's Sierra bootpack was not working despite me having updated to the same bios version that the bootpack is meant for, as discussed in the above threads. https://osxlatitude.com/index.php?/topic/9131-solved-e6420-monitor-sleep-turn-off-on-boot-fresh-install-of-el-capitan/?p=61321 But that DSDT was patched back when I was on El Capitan, do I need a new freshly patched DSDT for Sierra? Also why does the LoRes DSDT in the Sierra bootpack not work for me? This has been an issue for me since El Captain, is there something different about my E6420's monitor? It uses the Intel HD 3000 with the max resolution of 1366x768.

Current status of my Hackintosh I can boot using -f cpus=1. Internal Audio isn't working, brightness control isn't working. Without cpus=1 I'm being seen a message System uptime in nanoseconds: I need your help to solve the issue. Thanks in advanced. EDIT 1: I could able to solve kernek panic (cpus=1) using this. EDIT 2: Sound issue fixed with new extension from here. Now only issue is Wi-Fi. It's trying but cannot find any Wi-Fi network though there is two in my home. EDIT 3: Wifi issue is fixed using this kext. All solved! Felling Great

Hey guys. Any help at all on this would be greatly appreciated!!! I've been working pretty solidly on getting my x201 fully operational. Everything works sleep related. Beeps when going into sleep just like windows. (I think that's called ACPI sleep) And wakes just fine. EXCEPT the backlight stays off when waking back up. I was looking at the IOReg output before and after sleep and noticed a difference. (Below) Before Sleep, The IOPowerManagement for AppleBacklightDisplay only has 2 power states... Current and Max. After sleep, that same device has 3 power states. Current and Max like before. But now it has a DevicePowerState. What is happening here? And could this be the issue with the backlight not coming back on? Attaching the DSDT.aml from my system. dsdt.aml.zip
