Minor tweaks of https://github.com/lkmvip/netflix-4K-DDplus to allow automatic extension conversion using xcode tools. Better alternative to Boom3D-5.1 Audio for Netflix which only enables HE-AAC 5.1 and is non-free.
rm -rf Netflix_Extension; xcrun safari-web-extension-converter --macos-only --no-open ./ && pushd ./Netflix_Extension && xcodebuild && popd
Enable unsigned extentions, enable HE-AAC
option, spatial audio will now be
available and work with your AirPods.
Automatically select best bitrate also working as expected.
All other features are unknown compatibility wise.
