Encrypt your hard drive by activating FileVault in System Preferences > Security & Privacy. A recovery key will be generated which will allow access to your encrypted hard drive in the case of a forgotten password. Store this key securely (do not select the option to store your key with Apple).

3. Install Git with bash completion:
brew install git bash-completionOnce that's finished, open your .bash_profile in VS Code.
code ~/.bash_profileIf you don't have a .bash_profile yet, this will create a new file. add the line from Homebrew to finish installation:
[ -f /usr/local/etc/bash_completion ] && . /usr/local/etc/bash_completion

Set up GPG Suite
Download, install, and run it (the app: GPG Keychain Access).
The first time you run GPG Keychain Access, it will prompt you to generate your key. The default settings are good, don't forget to check the "upload to keyserver" box. Try to use a secure password, but not one you will forget. If you lose your password, it is impossible to recover. Consider using a password manager.
When you're finished, you'll have only your keys in GPG Keychain Access. To be most effective, you'll need some other PGP keys. From the Key menu (in the very top, Mac menu bar), select Search for Key....
Type bitpay.com and click search. When the results are returned, simply press Retrieve Key to import the PGP keys of all BitPay employees. Now you can send encrypted emails to any member of the BitPay team.
Explore the key listing in GPG Keychain Access. Learn about PGP key signing, and trade signatures with some other people to build your key's "Web of Trust".
