How to update Go version of tailscaled on macOS

I'm using the GitHub version of tailscaled on one of my Macs as a background daemon launched at boot. To upgrade to the latest version, try the following:

sudo launchctl stop com.tailscale.tailscaled
go install tailscale.com/cmd/tailscale{,d}@main
sudo $HOME/go/bin/tailscaled install-system-daemon
tailscale up

If you don't re-install the system daemon from your user's local installation, the old version will continue to get launched at boot.

Hope this helps someone!
