Above is the output when I was trying to upgrade google-chrome. It looks like I have Chrome version 66, but the server already has version 67. However, I was not able to upgrade it with brew cask upgrade. I'm wondering whether I have done anything wrong.

  • I got answer for my own question. Use --greedy.

There is no upgrade command available for brew cask. The GUI apps are updates by running Check for updates... from within the application which is generally found in the menu.

You can force install a newer version of the cask item by running brew cask reinstall <package>. In case of Google Chrome, run brew cask reinstall google-chrome.

You can use brew cask upgrade --greedy to upgrade all the GUI apps to respective latest version. From man brew-cask:

upgrade [--force] [--greedy] token [ token ... ]

Without token arguments, upgrade all the installed Casks that have newer versions available in the tap; otherwise update the tokens given in the command line. If --greedy is given then also upgrade the Casks having auto_updates true or version :latest.

  • There is brew cask upgrade actually. Who wants to upgrade each app separately if it could be done with a single command? The --greedy seems to do the trick.
