Slack for Mac

Slack's desktop app is the best way to use Slack on a Mac. Along with the features available in your browser, the app loads your conversations more quickly, gives you more control over notifications, and has better support for multiple teams.


Download and install Slack

There are two ways to download Slack for Mac: from the App Store, or the Slack downloads page.

App Store

Direct download

  1. Find Slack in the App Store.
  2. Click Install.
  3. To launch Slack, open a Finder window, select the Applications folder in the sidebar, then find and double-click the Slack icon.
  1. Visit the Slack downloads page at slack.com/downloads.
  2. Click Download.
  3. Once the download is complete, open a Finder window and select your Downloads folder. Double click the Slack .zip file to reveal the Slack app icon, if it’s not already there. 
  4. Drag and drop the Slack app icon over Applications in the Finder sidebar.
  5. To launch Slack, just double-click the Slack icon in your Applications folder.

Our new Mac app runs faster than ever. 🚗💨  If you already use the Slack app, install version 2.3.3 or higher, then replace the older app so you don't have to remember which one to use! 


Tips and tricks

Sign in to multiple teams

You can use the app to sign in to multiple Slack teams. Click your team name to open the Team Menu, then click Sign in to another team… to get started.

Switch teams easily

If you’re signed into multiple teams, it’s easy to navigate between them using the Team Switcher sidebar. You can even use keyboard shortcuts Cmd 1, Cmd 2, and so on to quickly switch between teams you’re signed in to. Just drag and drop the team icons to reorder them.

Add Slack to your dock

Once Slack’s running, you can choose to keep it in your dock. Just right-click the Slack icon, click Options and then click Keep in Dock.

Get dock icon notifications

You can set the dock icon to show a red dot when there’s unread activity in Slack. You can also set it to bounce when you receive notifications. To change these settings:

  1. Click your team name to open the Team Menu.
  2. Choose Preferences.
  3. Click the Notifications tab.
  4. Under Dock App Icon, set the preferences as you’d like them.

 

Troubleshooting

Having trouble? Here's what to try first:

  • Make sure you’re using the latest version of the app: slack.com/downloads.
  • Refresh the app with Cmd R.

If your app is using a lot of memory

  • Use the /collapse command in channels with lots of images and videos.
  • Sign out of any inessential teams.
  • If you have a lot of unread channels, marking them as read can help.

Using OS X 10.8 or earlier? New technologies like native notifications mean we can no longer support older Mac OSes. Going forward, the Slack desktop app is supported on OS X 10.9 and later. For info on upgrading your OS, see Apple's guide to upgrading.
