It seems that some brands of GT 710 DDR3 are no longer OOB supported by Big Sur. Make sure to use at least OpenCore 0.6.3 or newer with the public release of Big Sur. With macOS Big Sur, a huge change happened where Apple no longer makes it the default form of booting. This same bundle is what OpenCore uses to inject kexts, and was hoped to last quite some time. This contained a very minimal amount of kexts to get a mac booted. Since 10.7 Lion, the prelinkedkernel has been the default way for real Macs to boot. It makes sense that we migrate to OC for macOS Big Sur and future releases by Apple for the very best function and compatibility of our hackintoshes. This means they may no longer work properly with Clover, unfortunately. #Dell optiplex 7020 network driver download driversImportant Tip #3 All the Hackintosh related kexts and drivers by Acidanthera will be tested for their compatibility with the OC Bootloader exclusively. Haswell Refresh CPUs from early 2014 shipped in the Late 2014 27" iMac models. Be aware of this if you plan on installing Monterey at some point. If you will only use the iGPU to power your display, then Macmini 7,1 appears to be the best match for this hardware. That should work with Monterey, how well we don't know yet. The next closest iMac that is supported by Monterey would be the Broadwell based Late 2015 iMac16,2. UPDATE: J: Apple has dropped support for the 2014 iMacs in Monterey. It will also work well with first gen Haswell CPUs from 2013 such as the i5-4570 and i7-4770. The Late 2014 Retina iMacs had an optional Haswell refresh 4790K CPU so that is the best fit. I plan on using 15,1 with my i7-4790 based system. Late 2013 iMac14,1 and 14,2 have been dropped from support in Big Sur. #Dell optiplex 7020 network driver download installImportant Tip #2 Use the Late 2014, iMac15,1 SMBIOS to download and install Big Sur.

It's not simply an improved version of Clover. Important Tip #1 OpenCore is a Boot Manager like Clover. This thread will not support Clover users. It makes setting up your ist more complicated than simply using OpenCore so avoid it for now. Clover r5123+ has been modified for use with Big Sur.
