Common questions

Slack keeps asking me to update

This can happen if you have more than one version of Slack installed on your computer. For example, a copy of Slack might exist in both the Applications and Downloads folders. Here’s what you’ll need to do to fix this issue:

  1. Open Finder and search for Slack (make sure This Mac filter is selected).
  2. Highlight all copies of Slack and delete them.  
  3. In your dock, right click on the Trash icon and select Empty Trash.
  4. Get the latest version of Slack, and install it in the Applications folder.

Slack keeps asking for the administrator password

If Slack is installed to ~/Applications, users can update the app without special permissions. If Slack is installed to /Applications, users must be administrators of their Mac machines and have write access to and all files beneath it in order to update.

If the issue persists, ensure that the user has write permissions for the following. Replace example with your workspace or org name:

  • ~/Library/Caches/com.example.slackmacgap
  • ~/Library/Caches/com.example.slackmacgap.ShipIt

Be sure the user has write permissions for these specific files and folders.Replace example with your workspace or org name:

  • /Applications/
  • ~/Library/Caches/com.example.slackmacgap
  • ~/Library/Caches/com.example.slackmacgap.ShipIt

Tip: IT administrators can disable automatic updates and allow users to update Slack themselves. Learn how to deploy Slack for macOS.
