Yes, it's perfectly okay to keep those two template files. Only the file called config.plist will be used by OpenCore.
I'm sorry one more question, to get my Intel wifi to work I had the Airportltlwm.kext in the kext folder.
After copying AirportItlwm.kext into the OC/Kexts folder, do not use the OC snapshot feature. Instead, add a new entry in the Kernel section of config.plist:
<dict>
<key>Arch</key>
<string>Any</string>
<key>BundlePath</key>
<string>AirportItlwm.kext</string>
<key>Comment</key>
<string>OpenIntelWireless WiFi</string>
<key>Enabled</key>
<true/>
<key>ExecutablePath</key>
<string>Contents/MacOS/AirportItlwm</string>
<key>MaxKernel</key>
<string></string>
<key>MinKernel</key>
<string></string>
<key>PlistPath</key>
<string>Contents/Info.plist</string>
</dict>
Won't the ProperTree snapshot feature produce the code you showed?
The snapshot feature will incorporate every Kext and SSDT and EFI driver that exists in the respective directories. If we are certain that no extraneous files are present in those folders then we can use snapshot. But in general I am hesitant to use such “all or nothing” features.
Understand. I have the AirportItlwm and the two Intel BT kexts in my config.plist with Enabled=False so I can use my Fenvi T919 Wireless/BT card. I have those 3 kexts in there so I can try out the latest kexts versions w/o having keep modifying the config.plist for them; I just drop the updated kexts in the ...OC/kexts/ folder. Then, when I want to try the latest update, swap WiFi/BT cards and set the three kexts to Enable=True. YMMV.
Yes, already noted by @jjsenecal :
As a follow-up for those curious/interested, Resizable BAR (Base-Address Register) support, currently, only benefits folks who are running an AMD 6000 Series graphics card, have a motherboard that can enable it, and are playing games in Windows. Eventually, folks with an Ampere (3000) series Nvidia GPU will also reap the (slight) performance rewards. However, since macOS doesn't support either of these graphics cards today, Resizable BAR has zero benefit to the hackintosh community. MAYBE, Apple will grace us with AMD 6000 series drivers in Big Sur 11.3, but even if they do its highly unlikely that they will add Resizable BAR support since it primarily benefits Windows gamers.
