kfiatos Posted October 13, 2016 Share Posted October 13, 2016 I installed 10.12 on my Dell yesterday and updated to 10.12.1 beta 4. Trackpad ofcourse empty in preferences (known issue). Got wifi working (DW1550).The problem for me is audio and brightness. fn+insert -> brightness up and fn+f3-> brightness down are working but in strange range. I can have very bright display or no backlitght at all. If you know fix for audio, just point me the direction and Ill manage. I have perfectly working 10.11.3 on this setup and used ssdt and dsdt from that system. Am I missing something? Link to comment Share on other sites More sharing options...

kfiatos Posted October 13, 2016 Share Posted October 13, 2016 Okay, managed to get brightness working with intelbacklight.kext and dsdt (patched already for 10.11). No sound... Do you guys have idea where to start? Maybe someone already made it working? Link to comment Share on other sites More sharing options...
Alex Rivera Posted October 13, 2016 Author Share Posted October 13, 2016 Install these 3 kexts to /System/Library/Extensions ToSLE.zip AppleHDA_ALC292.kext CodecCommander.kext EAPDFix.kext Repair permissions and rebuild cache sudo chmod -Rf 755 /L*/E* sudo chown -Rf 0:0 /L*/E* sudo chmod -Rf 755 /S*/L*/E* sudo chown -Rf 0:0 /S*/L*/E* sudo touch -f /L*/E* sudo touch -f /S*/L*/E* sudo kextcache -Boot -U / If it fails re-run all commands again. Reboot Mine is working OK so far: Link to comment Share on other sites More sharing options...
kfiatos Posted October 13, 2016 Share Posted October 13, 2016 Alex could You please share ps2 kext that you're using? Wanna try. On mine 3 finger gestures only work for movement up and right. If I could get it to work if 4 directions Sierra could be my daily driver. Hdmi audio patch is the same as El Cap? Link to comment Share on other sites More sharing options...
Administrators Hervé Posted October 14, 2016 Administrators Share Posted October 14, 2016 Use Dr Hurt's latest (Release 4, posted yesterday). Should work perfectly on your E7440. It certainly does on my E6440. Link to comment Share on other sites More sharing options...

Unfortunately it doesn't for me. I have patched trackpad.prefPane, maybe this is an issue? I use Rehabman's last kext and it works great but no gestures. Dr Hurt's RC4 is choppy and not smooth for me, but gives me gestures. Merge of those 2 would be perfect Link to comment Share on other sites More sharing options...
Administrators Hervé Posted October 14, 2016 Administrators Share Posted October 14, 2016 This is strange because I understood the E6440 and E7440 have the exact same TouchPad. Try and remove your patched PrefPane to see if it makes any difference. Link to comment Share on other sites More sharing options...
kfiatos Posted October 14, 2016 Share Posted October 14, 2016 Could You please upload oryginal prefPane? I deleted mine unfortunately Edit: Nevermind. I left Sierra for now. 2nd time when put to sleep got black screen (fan was working), nothing worked so I pushed power. Next boot sdd corrupted, not able to repair. I had to format. Im not going to install it 3rd time. One good thing is that I made image of working state of sierra. Maybe later I will try again, but not now Link to comment Share on other sites More sharing options...
kfiatos Posted October 15, 2016 Share Posted October 15, 2016 Ok trying last time with Sierra. Herve, do You use 10.12 at the moment? Do you have trackpad prefpane working and what method did You used to get it working? Link to comment Share on other sites More sharing options...
