Moderators Jake Lo Posted July 28, 2015 Moderators Share Posted July 28, 2015 If you're using chameleon boot loader, then get the update files here for E6x20 under 10.10.4. Link to comment Share on other sites More sharing options...
Administrators Hervé Posted July 28, 2015 Administrators Share Posted July 28, 2015 Basically, you need the patched Intel SNB frame buffer (for Intel HD 3000 graphics) as that got overwritten by the 10.10.4 update. You need to repatch the kext after each update (or retrieve the patched kext from somewhere and replace the vanilla kext). https://github.com/toleda/graphics_Intel_framebuffers The patched kexts are available in my E6220 guide.
