Lenovo Thinkpad X260

So, I'm in the process of installing Tahoe on my Thinkpad x260 (I5 6500 with 8GB of ram) and I'm stuck with it not wanting to load the EFI (So, i can't boot into MacOS without the Recovery drive plugged in) and it won't let me install the network kext (so no internet) other than that, Tahoe is running great!

Any advice?
