Cache is a collection of temporary files created by your operating system and applications to store frequently accessed data. These files help speed up processes by reducing the time it takes to load data. For example, when you visit a website, your browser stores some elements of the site in cache so that the next time you visit, the page loads faster. This blog will explain how to clear cache on a Mac.
Types of Cache:
- System Cache: Files created by macOS to help the system run smoothly.
- User Cache: Files created by applications specific to your user profile.
- Browser Cache: Files stored by web browsers to speed up web page loading.
