Introduction

If you’ve been wondering, “How do I clear my cache on my Mac?”, you’re not alone. Whether your Mac feels slow or you’re trying to fix a browser issue, clearing the cache can help improve performance and solve common problems. This guide walks you through everything you need to know—from understanding what cache is to safely clearing it step by step.

What Is Cache on a Mac?

Cache files are temporary data stored by apps, browsers, and the system itself to speed up tasks. For example, Safari saves images from websites you visit so they load faster next time. Over time, though, these files can pile up and take up valuable space, or even cause software glitches.

Is It Safe to Clear Cache on a Mac?

Yes, in most cases, clearing your cache is safe and can even be beneficial. Just be careful not to delete system-critical files or caches related to ongoing tasks or software you’re currently using.
