Installing Homebrew

If you do not already have Homebrew installed, follow the steps below to install it. If you do, skip to the next section for updates/upgrades.

• Establish an internet connection.
• Install Homebrew, by clicking on this link and copy the script provided.
• Paste the script into your macOS Terminal or Linux shell prompt.

• Check for any warnings or follow-up actions provided in the Terminal.
• To ensure everything is up to date, run the following commands in the Terminal (copy and paste them in one at a time, hit Return after each, and allow each to complete prior to running the next command):
  • brew update
  • brew upgrade
  • brew cleanup
  • brew doctor

Installing DVRescue

In the Terminal, run the following commands to install the command line tools for dvrescue:

brew tap mediaarea/homebrew-mediaarea

brew install dvrescue
