Bigryangames Posted August 13, 2017 Share Posted August 13, 2017 After installing Sierra using Herves guide I had a fully working install. After updating to 10.12.6, the VGA port works but only outputs a grey screen. I have tried installing Sierra straight to the latest version, but get the same result. The screen is recognised, but not working. I have used the modified kext. Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted August 13, 2017 Moderators Share Posted August 13, 2017 After any upgrade, you have to re-install the patched kexts. Repair permission and rebuild cache. Link to comment Share on other sites More sharing options...
Bigryangames Posted August 13, 2017 Author Share Posted August 13, 2017 I have, I reinstalled all kexts from bootpack, repaired permissions and cache. The screen is there, it's just grey! Link to comment Share on other sites More sharing options...

Moderators Jake Lo Posted August 14, 2017 Moderators Share Posted August 14, 2017 delete the version in /E/E, backup the version in /S/L/E and install the patched file to /S/L/E repair permission and rebuild cache Link to comment Share on other sites More sharing options...
Administrators Hervé Posted August 15, 2017 Administrators Share Posted August 15, 2017 'just verified VGA output on my E6220 under Sierra 10.12.6 and all is Ok. Personally, I patch the vanilla SNB framebuffer kext as described in post #5 of my E6220 guide, increase the patched kext's version by adding a leading 9 (e.g.: 910.2.37) and place it in /L/E. Once permissions are repaired, this patched kext always takes precedence over the vanilla version left untouched in /S/L/E and the cache is rebuilt using that patched version. It's sustainable to OS updates. Patched_10.12.6_AppleIntelSNBGraphicsFB.kext_v910.2.37.zip I invite you to do the same. Avoid mistakes such as using Yosemite 10.10.5 patched SNB Framebuffer kext in Sierra 10.12.6. Link to comment Share on other sites More sharing options...
eazyone Posted August 17, 2017 Share Posted August 17, 2017 Hi. I've the same problem. No external monitors after update to 10.12.5, so I back to 10.12.3. Now everything works. Can You confirm that patched kext from post above works, so update to 10.12.5 dont ruin my hdmi port again? Link to comment Share on other sites More sharing options...
