- Use a third-party package manager to install GnuPG -
- Your macOS comes with a program called "Terminal" pre-installed, which we'll use to set up your encryption with GnuPG, using the command line. However, the default macOS package manager makes it difficult to install GnuPG and other pieces of free software (like Emacs, GIMP, or Inkscape).
-To make things easier, we recommend setting up the third-party package manager "Homebrew" to install GnuPG. Copy the link on the home page of Homebrew and paste it in Terminal. Click "Enter" and wait for the installation to finalize.
-When this is done, install GnuPG by entering the following code in Terminal:
-brew install gnupg gnupg2. After installation is done, you can follow the steps of the rest of this guide.
