Delete Stuck Namespace

Delete Stuck Namespace

Here be dragons. Use with extreme caution.

About

This script is designed to accept namespaces as a list of arguments and will perform a namespace child resource delete loop before terminating the namespace and any finalizers.

GlobalProtect toggle (start/quit)

Regain control over the annoying GlobalProtect macOS install

I need to use GlobalProtect because it's becoming the only VPN to access resources in my school. The VPN client is simple enough, but it does two annoying things:

  1. Registers itself to autostart on login
  2. Doesn't provide you with a simple 'quit' action

Here I'll show you how I fixed both issues in macOS 12.2 (Monterey).
