Basically, by 2020 Intel isn’t going to be supporting BIOS any longer, which is actually going to end up being good news for almost everyone, as near as I can tell, when everything becomes UEFI based on a full time basis?
Are you sure you aren’t already using UEFI on your hackintosh? Most recent motherboards are UEFI-based, and the Clover bootloader uses it. Legacy support/CSM is for older, BIOS-based systems
I had problems getting UEFI to work on my current setup. I am still using the legacy boot method. I do read on the forums that the latest hardware and clover live very happily together, have not tried it out yet.
But I was thinking more in terms of the possibility that Apple may lock OSX out of hardware that they dont manufacture.
