⛔. For more information on this issue, see #164.
If you experience issues signing in this way, you can ask to signin using a graphical dialog (provided by Mac App Store application):
$ mas signin --dialog firstname.lastname@example.org ==> Signing in to Apple ID: email@example.com
You can also embed your password in the command.

mas is integrated with homebrew-bundle. If
mas is installed, and you run
brew bundle dump, then your Mac App Store apps will be included in the Brewfile created. See the homebrew-bundle docs for more details.
When something doesn't work
If you see the error "This redownload is not available for this Apple ID either because it was bought by a different user of the item was refunded or cancelled.", it's probably because you haven't installed the app through the App Store yet. See #46.
mas doesn't work for you as expected (e.g. you can't update/download apps), run
mas reset and try again. If the issue persists, please file a bug! All your feedback is much appreciated
mas operates via the same system services as the Mac App Store. These exist as separate processes with communication through XPC. As a result of this,
mas experiences similar problems as the pasteboard when running inside
tmux. A wrapper tool exists to fix pasteboard behaviour which also works for
You should consider configuring
tmux to use the wrapper but if you do not wish to do this it can be used on a one-off basis as follows:
brew install reattach-to-user-namespace reattach-to-user-namespace mas install
Build from source
You can now build from Xcode by opening
mas-cli.xcodeproj, or from the Terminal:
Build output can be found in the
build/ directory within the project.
The tests in this project are a recent work-in-progress. Since Xcode does not officially support tests for command-line tool targets, all logic is part of the MasKit target with tests in MasKitTests. Tests are written using Quick.
