Mattermost desktop applications are available for Windows, Mac, and Linux operating systems. They support all the features of the web experience, plus:

  • Connect to multiple Mattermost servers from a single interface, and switch with shortcut keys.

  • Auto-start Mattermost when a user logs into their machine.

  • (Windows) Add Mattermost to Start menu, Taskbar, and System Tray.

  • (Windows/Mac) Deep link to the desktop app via mattermost:// protocol if app is already installed.

  • (Mac) Add Mattermost to the Dock.

  • (Linux) DesktopEntry for the application to more easily integrate into a desktop environment.

Homebrew users can install with brew install-cask mattermost. On macOS Catalina, this dialog can be triggered if the Mac Archive Utility is the default method. A deployment with an even number of masters provides the same level of fault tolerance as a deployment with one fewer master. For example, both four-master and three-master deployments can only tolerate a single failure; two-master deployments cannot tolerate any failures.

This issue can occur on Windows in a multiple-monitor setup. When you disconnect the monitor that Mattermost is displayed on, Mattermost continues to display at screen coordinates that no longer exist.

To resolve this issue, you can reset the desktop app screen location by deleting the screen location file. When the file is not present, the desktop app displays on the primary monitor by default.

To reset the desktop app screen location

  1. If the desktop app is running, right-click the Mattermost icon in the task bar and click Close Window.

  2. Open Windows File Explorer, and navigate to the %APPDATA%Mattermost folder.

  3. Delete the file bounds-info.json.

This issue can occur when localStorage has an unexpected state. To resolve the issue:

  • Windows: Open Windows File Explorer, navigate to the %APPDATA%Mattermost folder, then delete the LocalStorage folder.

  • Mac: Open Finder, navigate to the ~/Library/ApplicationSupport/Mattermost folder, then delete the LocalStorage folder.

  • Linux: Open the File Manager, navigate to the ~/.config/Mattermost folder, then delete the LocalStorage folder.

This issue can occur after a crash or unexpected shutdown of the desktop app that causes the app data to be corrupted. To resolve the issue:

  • Windows: Open Windows File Explorer, navigate to the``%APPDATA%Mattermost`` folder, then delete the IndexedDB folder and the Cookies and Cookies-journal files.

  • Mac: Open Finder, navigate to the ~/Library/ApplicationSupport/Mattermost folder, then delete the IndexedDB folder and the Cookies and Cookies-journal files.

  • Linux: Open the file manager, navigate to the ~/.config/Mattermost folder, then delete the IndexedDB folder and the Cookies and Cookies-journal files.

Clicking Show Details on the dialog provides logs. Ways to resolve the issue:

  1. Clear the cache via View > Clear Cache and Reload or CTRL+SHIFT+R.

  2. Go to App Settings via File > Settings or CTRL+COMMA and unselect hardware acceleration.

Append Mattermost.exe; to the Registry Key HKLMSYSTEMCurrentControlSetServicesCtxUviUviProcessExcludes and reboot the system.

  2. Select the Console tab.

  3. Right-click the log window and select Save As.

  4. Save the file and then send it along with a description of your issue.

You can open an additional set of developer tools for each server you have added to the desktop app. The tools can be opened by pasting this command in the Developer Tools Console you opened with the steps described above:

Catalina

document.getElementsByTagName('webview')[0].openDevTools();

Note that if you have more than one server added to the desktop client, you need to change the 0 to the number corresponding to the server you want to open in the Developer Tools Console, starting with 0 from the left.
