nawcom Posted January 9, 2017 Share Posted January 9, 2017 Just letting you know nv_display=1 isn't a valid boot flag for anything so feel free to get rid of that.I've read that this is a common issue with these series of cards in Sierra and it seems the solution is to use NVDAStartup.kext from 10.11.6 and replace the Sierra version with it. Usually it's installed into /System/Library/Extensions, but you can try putting it in /EFI/CLOVER/kexts/10.12. If you go the /System/Library/Extensions route then sure to rebuild the kernel cache and prelinkedkernel on whatever you install it on. I'll attach the kext to this post.If you want to try and get Sierra installed before fixing this issue, you can try booting with nv_disable=1 until you have everything installed and booting from the hard disk.

yellowpebble Posted January 10, 2017 Author Share Posted January 10, 2017 Thank you for your kindness.I tried NVDAStartup.kext.zip with boot flag "-v dart=0", but the result is as the attached picture "bootError1.jpg". Also another boot flags "-v -f npci=0x2000" got the attached picture "bootError2.jpg". Link to comment Share on other sites More sharing options...
nawcom Posted January 10, 2017 Share Posted January 10, 2017 That's interesting. If you boot with nv_disable=1 can you boot into the desktop or do you still lock up there? Also, is there any hard drive activity still while it's stuck at this state or has the computer completely locked up? Try typing text in to see. I've never seen this before myself.

yellowpebble Posted January 10, 2017 Author Share Posted January 10, 2017 With nv_disable=1, I can boot into the desktop. And the computer completely locked up state. If I type anyletters, I could not see. Link to comment Share on other sites More sharing options...
nawcom Posted January 11, 2017 Share Posted January 11, 2017 Here's a version that should be older than the one I previously uploaded. See if you run into the same issues. NVDAStartup.kext.310.42.25f01.zip 1 Link to comment Share on other sites More sharing options...
yellowpebble Posted January 16, 2017 Author Share Posted January 16, 2017 This is the crashed picture after restarting after clean install. Link to comment Share on other sites More sharing options...
nawcom Posted January 16, 2017 Share Posted January 16, 2017 Looks like the partition you installed to is messed up. You can repair it from Disk Utility from the USB install media, but if this is a brand new install then you may as well erase it and reinstall.

MaLd0n Posted January 16, 2017 Share Posted January 16, 2017 Dont use ssdt and dsdt in install. Ur dsdt have many patches, nvidia, etc. I think the problem is there. other config.plist have hdmi patch, remove. look it config.plist.zip Link to comment Share on other sites More sharing options...
