With OC 0.7.8 we can upgrade directly to Big Sur. But a full bootable backup should be made before starting. There are no guarantees in the Hackintosh world, and a simple full backup provides a much needed safety net.
It's set to Default which I assume means it's enabled? If I was to select one from the list in OC Configurator which would it be?
“Default” is okay. What is your OpenCore version? Would be good to upgrade to one of the recent versions (0.8.5 or newer).
Latest version I believe: 0.9.0
Which motherboard are you trying to upgrade? The EFI folder you posted earlier isn't one that I recognize.
Gigabyte designare z390 - Whats wrong with the EFI? I followed this guide and kept things up to date as best as I could. GPU is Different from your build (RX 550), I have the Fenvi T19 installed and an intek usb PCI card which seems to support USB 1 devices better. Im going to grab the EFI folder and attach it again.
Sorry, it looks like my first post had the wrong EFI folder attached - from a very old P8H67 build my wife uses now! Trust me, I'm not using that to boot from
TB3 -TB2 - Ethernet contraption survives sleep now. I've connected the USB cable to my Z690 mobo, and implemented GPRW for wake. I've slept the hack a couple of times, ethernet keeps working. Great.
Finally, I found the problem was due to RAM hardware glitch. It spent me a lot of time on addressing the problem and has been confused me for more than one year. A few days ago, I installed Windows on my another SSD and used aida64 to test 'stress system memory'. Then I found one of my memory sticks always trigger red warning. I tested it over and over again. The red warning still exists. So I applied for the after service to replace my current memory sticks with new one. As of today, it's working well both on Windows and macOS, I thought it may be software-related factors but actually hardware can be the cause sometimes.
