i upgrade from EI to Sierra.
And installed the latest Nvidia Web driver for my GTX970.
Unfortunately, i cannot startup properly after reboot. And i cannot modify the config.plist on Clover boot manager.
Anyone can help or tell me how to add "NvidiaWeb=1" on Clover boot manager ?
Thank a lots
Here's the thing. I couldn't boot either. My PC would skip Clover and boot straight to Windows.
But, I have a dualboot system, on the same SSD. And UEFI wasn't showing Clover in hardrive boot order. Just Windows Boot Manager.
I couldn't boot after upgrading to Sierra, either.
Here's what I did:
1. Boot from USB (any Mac OS X USB, I've actually previously created macOS Sierra USB, just in case something goes wrong. An El Capitan Installation USB will do just fine (I think).)
2. Even that required some changes while booting. You need to NOT USE safe mode, otherwise you can't mount EFI later (I couldn't). Try verbose & without caches. I had a few kernel panics, also... Anyways, whatever works for you, just get it to boot in your installation.
3. After booting, use efi mount script v3, and after mounting, go to /EFI/Microsoft/Boot/ , find bootmfgw.efi & rename it, to something like bootmfgw.efi.bckp
4. After that, Restart, go to BIOS/UEFI, and change Hard Drive Boot priority, to whatever works for you. Personally, BIOS made a "UEFI OS..." entry for me.
5. But then again, I couldn't boot to Windows now, even though macOS worked.
6. So I mount EFI again, and just changed my .bckp back to bootmfgw.efi, since I made an option in BIOS to boot Clover. I thought I'd give it a shot, and it worked.
7. Restart & Boom, both work now, and Windows partition is selected as default, which is super nice, since before, it was macOS, and I use W10 a lot more. I couldn't change the default, back then, so this is nice.
Also, you can't edit config.plist with Clover Config. Use efi mount script, find config.plist and open with text editor, then add nvidia web, like tonymacx86 EXPLAINED.
My GTX 750 still works without that. Just got nvda_drv=1, like I had in El Cpt.
The thing is, I got everything except audio to work. After upgrading to Sierra, my audio is gone. I relied on multibeast before, to give me audio for ALC887 and now there's no multibeast for Sierra.
Funny thing is, I hear something coming from the speakers, like static, IDK, even though there are no audio devices shown
I just got dualboot to work again, haven't messed with the audio yet.
