Moderators Jake Lo Posted July 21, 2019 Moderators Share Posted July 21, 2019 Sorry, seems it only works on High Sierra which is what I'm running. Link to comment Share on other sites More sharing options...
aufannada Posted July 21, 2019 Author Share Posted July 21, 2019 Sorry, do you use High Sierra on E7270 or E7470? Maybe there is a little difference so that the kext can't run on High Sierra on my E7270 because I tried to repeat several times but still with the same results, the screen went blank.

Moderators Jake Lo Posted July 21, 2019 Moderators Share Posted July 21, 2019 You could create your own with Hackintool. Click on Display tab Inject EDID, select MacBookPro (16:10) Export the kext and place in /E/C/k/O 1 Link to comment Share on other sites More sharing options...
aufannada Posted July 21, 2019 Author Share Posted July 21, 2019 Ok Jake, I've done it and succeeded. Now I have been able to connect HDMI to an LCD projector directly without blank screen, and it only takes 1-2 seconds to be able to display both images. I have also tried several experiments differently as a possibility after that and everything went normally without black screen. Thank you very much. Note : If I connect to an LCD projector using a mini-DisplayPort, the time needed is quite long, about 30-31 seconds. That is because the system is looking for the right resolution for the display, which is between 1920 x 1080 and 1366 x 768. And I prefer the resolution of 1366 x 768 because it matches what is displayed on the laptop screen. But that doesn't matter to me, I never or rarely use mini-DisplayPort for mirroring because if use it the sound won't come out (sound is only on the laptop) or no DP audio.

aufannada Posted July 21, 2019 Author Share Posted July 21, 2019 Now, the HDMI connection that was previously problematic has now been resolved. There are 2 more which in my opinion will also be resolved. The first is the SD Card Reader, and the second is the Trackpad. Could you help me again to finish both?

Moderators Jake Lo Posted July 21, 2019 Moderators Share Posted July 21, 2019 miniDP audio should work if the right patch is added. Post your debug files with the miniDP connected. There's some development for the SDCard for this model but had stopped for a while (Realtek RTS525A). Check here. You can donate money if you want further development to occur as it's very time consuming. Dr. Hurt has made some development for the Alps touchpad, but it only works well for older v3 and maybe v5. Newer v7 and v8 definitely has issue. You can try it here. He too has stopped further development. For Mojave, you'll have to use the version compiled by Bronxteck.

aufannada Posted July 21, 2019 Author Share Posted July 21, 2019 Sorry Jake, I did not find the version 3 to download in that thread. Maybe you have the file? Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted July 21, 2019 Moderators Share Posted July 21, 2019 I mean the version of touchpad on the system, not kexts version. For example: E6420 and E6430 has v3 touchpad E7440 has v5 touchpad E7450 has v7 touchpad E7470 has v8 touchpad The kext supports v3 and v5 quite smoothly, and somewhat supports v7 and v8, just not smoothly. With the kexts install, run this in terminal to determine what version you have. I'm pretty sure E7270 is the same as the E7470. log show | grep ALPS Link to comment Share on other sites More sharing options...
aufannada Posted July 28, 2019 Author Share Posted July 28, 2019 @Jake Lo Ok, I understand Jake. I have checked using the command above, and I found that my E7270 has a v8 touchpad version and does have problems after using the kext from Dr. Hurt and also from Bronxteck. So now I don't use it anymore. And I already considered the problem complete. For this touchpad case I will not find a solution again. Thank you for helping to solve the problem even though I failed to find the best solution.

Moderators Jake Lo Posted July 28, 2019 Moderators Share Posted July 28, 2019 I don't see any external monitor connected. Make sure the miniDP is connected to a monitor and post the IOREg file again or the full debug file while it's connected or HDMI monitor Link to comment Share on other sites More sharing options...
