Bu Yezi Posted July 24, 2021 Share Posted July 24, 2021 @Jake Lo Please ignore my previous errors. Finally I successfully installed Big Sur. Like you guesses, I think one of my USB port is faulty. Thanks a ton for your time! Now, please help me to understand the following. I saw this on another thread: My trackpad was working except the left and right buttons. I replaced the VoodooPS2 controller kext that you suggested to another person who's using the same latitude E5470. After replacing the Kext file buttons also stop working. And I have no clue how to enable voodoops2 plugin for VoodooInput and VoodooPS2Mouse. Please help how to do it. Link to comment Share on other sites More sharing options...
Bu Yezi Posted July 24, 2021 Share Posted July 24, 2021 Hi @Entropic , you faced similar issue right? would you help me with this Voodoops2 plugin? Other thread is closed hence I'm asking here, hope it's OK. Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted July 25, 2021 Moderators Share Posted July 25, 2021 Replace with this EFI, update to latest OC v0.7.1 Configured for Intel Wifi / BT If you have other, you'll need to make the adjustments. EFI.zip Link to comment Share on other sites More sharing options...
Bu Yezi Posted August 6, 2021 Share Posted August 6, 2021 Wow! Thanks a ton @Jake Lo that worked. I never expected my Intel Wifi card working on Hackintosh. Fantastic! Sorry for the late reply, I was stuck in another city due to pandemic. Back home and replaced EFI folder with yours, boom! All working!!! Link to comment Share on other sites More sharing options...
Bu Yezi Posted August 9, 2021 Share Posted August 9, 2021 Hi @Jake Lo, I have a 3.5mm Lapel mic that connected to an Audio jack Y splitter for the Mic and Headphones. My iMac Catalina recognise the "Audio splitter + Mic + Headphones", but this Big Sur build is not recognising the external Microphone. Audio preferences I can see "Line In Microphone" also listed in the input options. But Mic is not working. How to fix it? Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted August 9, 2021 Moderators Share Posted August 9, 2021 if the 'Line in Mcrophone' doesn't work, then you'll need to learn how to patch your AppleALC for ALC293. As far as I know, there's only patch made for Dell (layout-id =11 which is what you have). There's layout-id 28 and 29 for Lenovo and 30 for an Hasee ZX8 ( not familiar with this system). Give those a try if you like. There are a few guides out there on how to patch AppleHDA but I had never try. Not my cup of tea to be honest.

Bu Yezi Posted August 12, 2021 Share Posted August 12, 2021 Hey @Jake Lo , sorry to bother you again. Just noticed, after replacing the EFI Brightness control is not working. Any fix? Also, I updated the OC manually replacing the files after replacing the EFI. Still OCC says it "you seem to have an old version of OpenCore bootloader."

Bu Yezi Posted August 12, 2021 Share Posted August 12, 2021 Yes, that worked. Thanks a ton! Display Brightness Working. OCC warning is disappeared. Now only "Line-in port" is not working. I'll try different layout IDs as Jake suggested. Link to comment Share on other sites More sharing options...
