Moderators Jake Lo Posted April 6, 2017 Moderators Share Posted April 6, 2017 You could manually patch your FB for your version of OS X following his recommendation in the guide. You could use 0xED or HexFiend. Link to comment Share on other sites More sharing options...

k00l3 Posted April 6, 2017 Author Share Posted April 6, 2017 Feedback section is not for support. Moving to the correct section. Apologies You could manually patch your FB for your version of OS X following his recommendation in the guide. You could use 0xED or HexFiend. Are you referring to this. "Thanks to JakeLo who passed on the details for testing, the Yosemite Azul frame buffer kext can now be binary patched to support HDMI output: the patch consists of replacing Hex code 01050900 00040000 87000000 by Hex code 01051200 00080000 87000000 in binary file AppleIntelFramebufferAzul through perl script or via a binary editor such as 0xED." I used the E6440_i5-4300M_HD4600_Sierra-Pack so I assumed this was patched already. Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted April 6, 2017 Moderators Share Posted April 6, 2017 Correct, but perhaps you might be on a different version of OS X, then patching your version is the better way to be certain. Make a copy of your vanilla FB first. This is assuming you're using Chameleon and not Clover which could be done on the fly. Link to comment Share on other sites More sharing options...
k00l3 Posted April 6, 2017 Author Share Posted April 6, 2017 I am on 10.12.4. using enoch-rev2848 and followed Herve's guide for 10.12.x install found here So I used the AppleIntelFramebufferAzul.kext along with all the kext from from the E6440_i5-4300M_HD4600_Sierra-Pack, I used Hex Fiend to apply the patches/changes found from this thread below before: 01050900 00040000 87000000 after: 01051200 00080000 87000000 before: 02040900 00040000 87000000 FF000000 after: 03060900 00020000 87000000 FF000000 but I get the same result OS freezes halfway through boot Correct, but perhaps you might be on a different version of OS X, then patching your version is the better way to be certain. Make a copy of your vanilla FB first. This is assuming you're using Chameleon and not Clover which could be done on the fly. Where would I get a vanilla FB? (I assumed the pack Herve created is prepatched) Link to comment Share on other sites More sharing options...

So I am not sure what else to do now , I really would like to get the HDMI output working everything else is working perfectly. Is there a vanilla Sierra kext? Sorry but I am stuck here Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted April 6, 2017 Moderators Share Posted April 6, 2017 You can restore the vanilla kext from your USB installer. try patching only the HDMI and not the DVI/DP before: 01050900 00040000 87000000 after: 01051200 00080000 87000000 Link to comment Share on other sites More sharing options...
