Switch iTerm2 color preset automatic base on macOS dark mode.
View iterm2_switch_automatic.md

The latest beta (3.5) includes separate color settings for light & dark mode. Toggling dark mode automatically switches colors.

Vist iTerm 2 homepage to download the beta. Thanks @stefanwascoding.


  1. Add switch_automatic.py to ~/Library/ApplicationSupport/iTerm2/Scripts/AutoLaunch with:
View .aliases.backup
#!/usr/bin/env bash
# Easier navigation: .., ..., ...., ....., ~ and -
alias ..="cd .."
alias ...="cd ../.."
alias ....="cd ../../.."
alias .....="cd ../../../.."
alias ~="cd ~" # `cd` is probably faster to type though
alias -- -="cd -"
