Frequently Asked Questions

What happens when I clear Slack cache on Mac?

Clearing Slack cache removes temporary files, images, and data stored locally on your Mac. Your messages, channels, and settings remain intact, but the app may need to reload some content when you restart it.

How often should I clear Slack cache?

You only need to clear Slack cache when experiencing issues like slow performance, loading problems, or high storage usage. Most users don't need to do this regularly unless they notice specific problems with the app.

Will clearing cache delete my Slack messages or workspaces?

No, clearing cache won't delete your messages, workspaces, or any important data. It only removes temporary files stored locally on your device. All your conversations and settings are safely stored on Slack's servers.
