Hi all!
So i seem to be having a strange issue - I have a Lenovo Yoga X1 4th Gen twith Big Sur, and that works great!
-HOWEVER- I wan to downgrade to Mojave so I figured that, since OpenCore is already setup and ready to go, I could just backup the EFI folder, boot up a Mojave USB, install, re-copy the EFI over and go!
That only seems to kind-of work. If I do that, Mojave does install and boot up fine but I loose the ability to use the touchscreen. It works flawlessly in Big Sur but not Mojave. I believe it's something to do with the Voodooi2c kext.
The current version installed is 2.6.5, and I have tried going backwards on the off chance that perhaps there's been a significant change from Mojave to Big Sur that causes this issue but I'm getting nowhere.
