Setting up a new machine

Setting up a new Mac for web development with Rails

This is my own howto to setup new machines, but you might find it helpful as well.

## General settings

  • In Finder -> Preferences set it to show your home folder, hard drives, external drives, filename extensions, etc.
  • Make Finder show Library: run chflags nohidden ~/Library/ within a terminal
  • Disable holding key pressed to display accents and enable repeat keys: defaults write -g ApplePressAndHoldEnabled -bool false
  • In Preferences->Dock Select "Scale Effect" in the "Minimize Using" field and deselect the "Animate Opening Applications" option.
