Clear Slack Cache on Mac

To delete the Slack cache on your Mac and resolve performance lags, you should navigate to the Help menu in the app, select Troubleshooting, then click Clear Cache and Restart. Our team suggests this quick fix to refresh your workspace, remove corrupted data, and restore a smooth, stable connection instantly.

Why clear Slack cache on Mac?

You should reset the Slack cache on your Mac to fix persistent performance issues, resolve software bugs, and free up valuable disk space. Our experts have found that a corrupted or overloaded cache often leads to slow loading times, display errors, and notification failures. Regularly clearing it ensures your app runs smoothly.

A note from our experts: 

 

While a specific app reset is great, we recommend you clear the Slack cache on a Mac as part of a deeper system refresh to reclaim maximum storage. Based on our experience, built-in tools often leave behind hidden leftovers in system folders that continue to hog memory. We suggest using MacKeeper’s Safe Cleanup, as it is a macOS utility software that offers memory optimization by targeting these redundant files.

 

Follow these steps to deep-clean your cache:

1. Launch the MacKeeper app and navigate to the Safe Cleanup tab to begin a full system scan for junk.
2. Filter through the detected logs and caches to ensure you are only removing unnecessary data.
3. Click the Clean Junk Files button to instantly wipe away the identified clutter and boost your Mac’s efficiency.

When clearing Slack cache isn’t necessary?

To start with, clearing the Slack cache isn't necessary if the app is running smoothly. The cache actually speeds up loading by storing temporary data for quick access to messages and files. As our internal tests show, it only becomes needed when you experience slow performance, connection issues, or excessive storage usage. That’s why if you have a stable internet connection and aren't facing glitches, it is generally fine to let the cache build up to enhance your user experience.

Will clearing Slack cache log you out or delete messages?

No, clearing the Slack cache will not delete your messages, as those are safely stored on Slack's remote servers. However, based on our team's hands-on evaluation, the process might log you out of your specific workspace and will remove temporary files that help the app load faster. While clearing "data" on mobile devices often logs you out, on a Mac desktop, the Clear Cache & Exit option usually keeps you logged in while forcing a refresh in order to fix display bugs.

How to delete Slack cache on Mac?

To delete the Slack cache on a Mac, the easiest way is through the app's built-in menu: open Slack, click Help in the top menu bar, hover over Troubleshooting, and select Clear Cache and Exit. This automatically removes temporary files and restarts the app for you. For a more thorough manual removal of associated files, you can use Finder to access and delete folders within ~/Library/Application Support/Slack/, ensuring every hidden leftover is fully gone.
