What's Working?

Pretty much everything

Bluetooth
Sleep
iMessage / Facetime
Ethernet

Upon MacOS installation:

Open Terminal and type this in:

ifconfig en0 media 1000baseT mediaopt full-duplex

Thunderbolt
Sidecar (with USB-C Connection)

One issue I have with Sidecar:

When connecting my iPad to Sidecar and simultaneously in a Zoom Meeting + using OBS to record, computer will restart. I'm not sure if this is due to a memory leak, but this is a specific problem only when I am using Sidecar.
