Clearing the cache on your Mac can help improve system performance and free up storage space. The cache stores temporary files that speed up processes, but over time, these files can accumulate and slow down your system. Here’s a step-by-step guide to help you clear your cache on a Mac.
What is Cache?
Before diving into the steps, it’s important to understand what cache is. Cache consists of temporary files created by apps, browsers, and the operating system to speed up loading times and enhance performance. These files include website data, images, and scripts that your system accesses frequently.
Why Clear Your Cache?
- Improve Performance: Over time, cache files can slow down your Mac by taking up valuable disk space.
