A simple command line interface for the Mac App Store. Designed for scripting and automation.
Homebrew is the preferred way to install:
brew install mas
MacPorts works as well:
sudo port install mas
⚠️ Note that macOS 10.15 (Catalina) is required to install mas from MacPorts or the core Homebrew formula.
We provide a custom Homebrew tap with pre-built bottles for all macOS versions since 10.11.
To install mas from our tap:
brew install mas-cli/tap/mas
mas requires Swift 5 runtime support. macOS 10.14.4 and later include it, but earlier releases did not.
Without it, running
mas may report an error similar to this:
dyld: Symbol not found: _$s11SubSequenceSlTl
To get Swift 5 support, you have a few options:
Alternatively, binaries are available in the GitHub Releases.
Each application in the Mac App Store has a product identifier which is also
used for mas-cli commands. Using
mas list will show all installed
applications and their product identifiers.
$ mas list 446107677 Screens 407963104 Pixelmator 497799835 Xcode
It is possible to search for applications by name using
mas search which
will search the Mac App Store and return matching identifiers.
--price flag to include prices in the result.
$ mas search Xcode 497799835 Xcode 688199928 Docs for Xcode 449589707 Dash 3 - API Docs & Snippets. Integrates with Xcode, Alfred, TextWrangler and many more. [...]
To install or update an application simply run
mas install with an

If you want to install the first result that the
search command returns, use the
$ mas lucky twitter ==> Downloading Twitter ==> Installed Twitter
Please note that this command will not allow you to install (or even purchase) an app for the first time: use the
purchasecommand in that case. ⛔ The

Please note that you may have to re-authenticate yourself in the App Store to complete the purchase. This is the case if the application is not free or if you configured your account not to remember the credentials for free purchases.

If you experience issues signing in this way, you can ask to sign in using a graphical dialog (provided by Mac App Store application):
$ mas signin --dialog email@example.com ==> Signing in to Apple ID: firstname.lastname@example.org
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.
Over time, Apple has changed the APIs used by
mas to manage App Store apps, limiting its capabilities. Please sign in
or purchase apps using the App Store app instead. Subsequent redownloads can be performed with

mas sees from the app bundles on your Mac don't always match the versions reported by the App Store for
the same app bundles. This leads to some confusion when the
upgrade commands differ in behavior from
what is shown as outdated in the App Store app. Further confusing matters, there is often some delay due to CDN
propagation and caching between the time a new app version is released to the App Store, and the time it appears
available in the App Store app or via the
mas command. These issues cause symptoms like
#384 and #387.
If you see this error, it's probably because you haven't installed the app through the App Store yet. See #46.
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.
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,
experiences similar problems as the pasteboard when running inside
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
You can build from Xcode by opening the root
mas directory, 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.
