How to Clean a MacBook Cache
A computer's cache stores temporary Internet files that a browser can use to pull up websites quickly. Instead of downloading information from a website, the browser simply loads the web page from the cache. Unfortunately, this can sometimes cause an outdated version of a webpage to load instead of the updated version. You should periodically clean the cache in your computer to prevent this. Cleaning the cache on a MacBook, Apple's signature laptop model, is a simple and straightforward task that requires only a few moments.
Click on "Safari" from the Apple dock on your MacBook.
Click the "Safari" button in the file menu. A drop-down menu appears.
Scroll down and click on "Empty Cache." A warning dialog box appears.
Click on "Empty." Safari deletes all files in the MacBook's cache. Restart Safari.
