AirPlay and Touch Bar = Network Disaster
You would be mistaken if you thought switching to ethernet would fix everything in macOS. There are three options for USB Ethernet chipsets that are supported in macOS without drivers: RTL8153, AX88178, AX88172A (not B or C). When using a RTL8153, I've experienced extremely high CPU usage (it's a shitty user-mode driver), and I've had the adapter drop out after transferring >20GB of files over it. I ended up buying the AX88178 and AX88172A adapters which are supported by the kernel. Based on my limited testing, only the AX88172A chipset is stable enough for 24/7/365 connectivity. Unfortunately the AX88172A is only 100Mbit, so consider it if you value stability > throughput<p>The thread that sparked this rabbit hole:<p><a href="https://discussions.apple.com/thread/252387604" rel="nofollow">https://discussions.apple.com/thread/252387604</a><p>TLDR: 2022 and we are still stuck with 100Mbit adapters on macOS
