A lot of useful packages come from [Cask](https://github.com/Homebrew/homebrew-cask), which is now included as part of Homebrew itself. To use them from Homebrew, you are supposed to use `brew cask` instead of just `brew`. For example, the correct command to install gimp would be: `brew cask install gimp` Here is an example of pacapt failing to install gimp: `$ pacapt -S gimp` ``` Error: No available formula with the name "gimp" It was migrated from homebrew/core to homebrew/cask. You can access it again by running: brew tap homebrew/cask And then you can install it by running: brew cask install gimp ```
