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.

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.

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

Where would I get a vanilla FB? (I assumed the pack Herve created is prepatched)

 I tried the vanilla kext (manually patched myself) and the patched kext from that post both with the same result, as soon as I plug in HDMI os freezes.

 

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

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 

 

Ok I got it off the installer  , probably a really stupid question but there are 5 entries for 01050900 00040000 87000000. do I replace all 5 with  01051200 00080000 87000000  or is there one at a specific offset ?
