Hmmm doesn't say here... dmesg | grep -i input try with this command. Also I assume your Ethernet does not work either, as you have a Realtek Controller instead of Intel

And also disable VoodooPS2 R6. That's for Alps

[pkombala]

full working

[SkyrilHD]

Great! Will reopen the issue again until I update the README

[SkyrilHD]

For anyone who own a 3550 2015 model, need to do these changes to make a fully working Hackintosh:

Remove

• IntelMausi.kext

Add

• RealtekRTL8111.kext (Download here)

Config changes

• Update Kernel>Add by adding RealtekRTL8111 and removing IntelMausi
• change layout-id to "3"; The line you need to change:

  Dell-Exx50-Hackintosh/OpenCore/EFI/OC/config.plist

  Lines 414 to 415 in ae65a86

  	<key>layout-id</key>
  	<data>CwAAAA==</data>

UPDATES

• 15.07.2022: Changing VoodooPS2 is not needed any more, since with v2.5 VoodooPS2 by acidanthera is included.

[pkombala]

One more small issue after sleep keyboard malfunctioning any help?

[SkyrilHD]

Since I don't use acidanthera's kext, I don't know

[pkombala]
