vanquybn Posted December 21, 2015 Share Posted December 21, 2015 Hi all, I am using el capitan on my laptop dell with nvidia card, everything working fine except the "boot second stage" screen. Anyone has experience about this issue on nvidia graphics card please advise. Thank you! Link to comment Share on other sites More sharing options...
Administrators Hervé Posted December 21, 2015 Administrators Share Posted December 21, 2015 2nd boot stage garble is a well-known glitch affecting most if not all Hackintoshes since Yosemite. It needs IOGraphicsFamily kext to be binary patched. In EC, it should be something like replacing hex string 0100007517 by 0100007417. Link to comment Share on other sites More sharing options...

Administrators Hervé Posted December 21, 2015 Administrators Share Posted December 21, 2015 2nd (or final) stage boot issue is just a short screen garbled. It does not prevent reaching OS X desktop or enjoying full graphics acceleration. Make sure the patch you've posted above applies to EC because, as far as I remember, it differs between versions of OS X. Link to comment Share on other sites More sharing options...
vanquybn Posted December 21, 2015 Author Share Posted December 21, 2015 The 2nd stage boot work correctly If I disable Nvidia card and use HD4600. So I think it is issue of NVD card on this OS :V Link to comment Share on other sites More sharing options...
