sudo using Touch ID or Apple Watch double press

It is possible to enable Touch ID to authorize sudo and other administrative tasks. If you have linked an Apple Watch you'll also be able to double press the Apple watch side button to approve.

You need to do the following in terminal:

cd /etc/pam.d/
sudo cp sudo_local.template sudo_local

WireGuard

How to set up WireGuard as an iOS VPN configuration in order to tunnel all traffic from an iOS or iPadOS device through a Linux server.

While there are many configurations possible, my intentation was to secure the traffic from my iOS device by routing it securely through a Linux server. As such, this HowTo will show you how to set-up an initial working configuration, which you can customize afterward.

Most likely things will be missing, such as how to configure the firewall or the init scripts on your Linux distribution. As it won't be possible to cover all Linux flavors this HowTo will attempt to give you a working WireGuard configuration, leaving it up to you to fill-in the blanks. Feel free to write a comment to touch upon your specific situation to help others that might stumble upon this HowTo :)

Note: In these configuration examples I use 10.8.0.1/24 and 10.8.0.2/24. However, as WireGuard IPs may not overlap your other network interfaces

Sometimes unenrolling from the macOS beta feed does not work properly.

You can fix this by enrolling / unenrolling through Terminal:

sudo /System/Library/PrivateFrameworks/Seeding.framework/Versions/A/Resources/seedutil enroll DeveloperSeed
sudo /System/Library/PrivateFrameworks/Seeding.framework/Versions/A/Resources/seedutil unenroll
