Is your computer too slow? The changes you made to your website do not appear when you open it in your browser? To avoid these problems, it is important to clear your computer’s cache on a regular basis, a simple solution that will greatly improve the performance of your device.

 

What is cache and why should it be cleared?

The cache is all the information that is automatically saved on your computer when you use a program or when you surf the Internet. For example, when you visit a website for the first time, your computer saves a copy of some of its data so that you can open the site more quickly the next time you visit.

This process, which is useful, can however lead to an accumulation of superfluous files on your computer and affect its performance. Moreover, not clearing your computer’s cache often enough can prevent you from seeing the latest versions of the websites you visit, since your browser opens them from old data stored in the cache memory.

 

How to clear cache on Mac ?

3. Type ~/Library/Caches, then press Enter. You will then be redirected to the folder containing part of your computer’s cache memory.


4. Open each folder and delete its contents.
5. Repeat the first two steps,
6. but replace ~/Library/Caches with /Library/Caches (without “~”) in the second step.
