Install Homebrew. It will fail to install packages by default due to issues writing to /usr/local. To fix this:

sudo chmod -R g+w /usr/local

Change the following settings using the Mac system preferences

• Key Repeat – all the way long
• Delay Until Release – all the way short
• Tracking speed – faster

Install Karabiner, so that you can remap keys.

Go to “Misc & Uninstall” then click “Open private.xml”. Paste the code below. Switch back to the main tab “Change Key” and hit “Reload XML”. Now check “Swap Command and Control unless tabbing through windows”
