mdub Posted January 6, 2017 Author Share Posted January 6, 2017 Yes IntelBacklight.kext is installed and Brightness Fix is patched to DSDT. I have slider in system prefs but no brightness icon when pressing f11/f12. Will try Karabiner setup. Should I patch DSDT with GFX0 -> IGPU for GPU power management?

Moderators Jake Lo Posted January 6, 2017 Moderators Share Posted January 6, 2017 Yes, make sure to do it to all the SSDT where it applies as well. Link to comment Share on other sites More sharing options...
mdub Posted January 7, 2017 Author Share Posted January 7, 2017 cool, all done with that and working. is there a kextstopatch to get HDMI/VGA ports working? Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted January 8, 2017 Moderators Share Posted January 8, 2017 This one works for me. Make sure you have UseIntelHDMI enabled under Devices <dict> <key>Comment</key> <string>HD 520 HDMI # 1</string> <key>Disabled</key> <false/> <key>Find</key> <data> AQUJAAAEAAA= </data> <key>Name</key> <string>AppleIntelSKLGraphicsFramebuffer</string> <key>Replace</key> <data> AQUJAAAIAAA= </data> </dict> this second one is not needed for my E7470. It disables audio with miniDP so I left it disabled <dict> <key>Comment</key> <string>HD 520 HDMI #2</string> <key>Disabled</key> <false/> <key>Find</key> <data> AgQKAAAEAAA= </data> <key>Name</key> <string>AppleIntelSKLGraphicsFramebuffer</string> <key>Replace</key> <data> AgQKAAAIAAA= </data> </dict> Link to comment Share on other sites More sharing options...
mdub Posted January 10, 2017 Author Share Posted January 10, 2017 first kextstopatch isn't working, I get a video out to my monitor via HDMI but internal laptop screen cuts out then external monitor gets garbled and cuts out after a few minutes. I read ports 0, 5, 7 correspond to internal, HDMI and VGA ports, do you know what strings those ports correspond to and how to patch accordingly? also audio doesn't work after resuming from sleep Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted January 10, 2017 Moderators Share Posted January 10, 2017 Make sure you have EAPDFix installed for sound after sleep. There's no VGA on my system nor on Mac's, so I never tried it. 0 = Internal 5 = HDMI 6 = DisplayPort There's no port 7 on my system. HDMI can cause hanging or not respond sometimes when hot pluggin/unplugging. DisplayPort seems to be more reliable on my system. You can try experimenting, see Hervé's guide on Haswell HD4600/HD4400 for ideas. Link to comment Share on other sites More sharing options...
mdub Posted January 10, 2017 Author Share Posted January 10, 2017 Ok I'll try that out thanks I accidentally installed AppleIntelInfo.kext to S/L/E/ and now my system won't boot. I managed to delete it by booting into windows. How would I rebuild the kext cache from terminal off the USB installer? Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted January 10, 2017 Moderators Share Posted January 10, 2017 Can you boot to USB installer and then select the internal drive to boot? Link to comment Share on other sites More sharing options...
mdub Posted January 11, 2017 Author Share Posted January 11, 2017 No I get a kernel panic when it tries to load AppleIntelInfo.kext . Same thing with safe mode too :/ Link to comment Share on other sites More sharing options...
