I noticed some packages provided by homebrew-cask uses a url of the latest version and a version number of "latest" such as dropbox and chrome. Thus they will never be upgraded with brew upgrade. Is there any simple way to update such packages using homebrew-cask?

And if I call brew cask install dropbox again, it shows there already exist some cache of old version, which I feel so dumb.

Try this command:

brew cask install dropbox --force

Please consider logging a bug over at homebrew-cask about your concerns with updating this kind of cask.

  • is it safe to use? does it cleanly remove the old version while keeping its configuration? Jun 1, 2015 at 6:31
  • @ErikAllik your comment will unlikely to be seen here by the brew cask developers. Please can you start a new question or log a bug with homebrew-cask directly. Jun 1, 2015 at 6:34

As of today brew cask does not implement upgrade but there is an open issue that tracks this at https://github.com/caskroom/homebrew-cask/issues/4678

If you want to see it implemented sooner you could add your small contribution by fixing one of the todo items listed there.


This has really irked me so I created this script to update all Brew apps and allow the user to choose which Cask apps to update. You can exclude apps from consideration too.


brew upgrade --cask dropbox

I find this to be the most convenient way of upgrading a specific app using brew.
