# If you're having issues with Tailscale after a reinstall, try cleaning up.
# Tailscale recommends the following. I've just scripted it for ease:
# https://tailscale.com/kb/1069/uninstall?q=uninstall&tab=macos+%28standalone%29

# Oh would you look at that, if you've got brew, just use that.
# https://github.com/Homebrew/homebrew-cask/blob/master/Casks/t/tailscale.rb

# NOTE:
# I made this because I was having major authentication issues and I got tired of tidying up for my reinstalls.
# Turns out the issue was that my corporate network suddenly started causing issues. 
# Moral of the story... Issues? Try a hotspot before anything else.
