Please help me with a few problems with my Catalina installation.

I've just finished (almost) my first hackintosh project, installing Catalina but my four largest issues/concerns (for now) are:

1. I can't get Ethernet to work; I've installed the IntelMausi and IntelMausiEthernet kexts but still have no luck.
2. I can't get 4k resolution. The highest available in system preferences is 2560x1440.
3. Every time I reboot I have to remount the EFI partition - I'm not sure if this is how it is supposed to be.
4. There are red lightning bolts next to sections in clover configurator.

My components are:

• Motherboard: Gigabyte GA-H97M-D3H
• Processor: Intel® Core™ i7-4790K
• GPU: Onboard graphics Intel HD Graphics 4600

My config.plist is here

Screenshots of my installed kexts and red lightning bolts are found here

I followed the vanilla guide from the sidebar meticulously and am not sure what I did wrong. Any help would be appreciated.
