What is cache?">What is cache?

Before we dive into it, you may be wondering what cache is exactly. Cache is temporary data your Mac saves from websites and applications to help them load faster. Saving cache files is mostly a good thing because it improves the overall experience of the browser and the application. However, while your computer will save cache automatically, you will have to manually delete it in most cases.

What about cookies? Cookies are certainly similar to cache, but the big difference is in their function. While cache files are commonly loaded assets, cookies specifically relate to user choices. Cookies consist of your login info for other sites and your browsing history. This is one of the typical pieces of information digital advertisers use to target you for ads.

In this guide, we will focus on how to clear your cache on your Mac. To delete cookies, you can read our guide on deleting cookies.

Step 3: A new option should appear at the top of your screen called Develop. Click it, scroll down, and select Empty Cache. At this point, you can turn off the Develop menu or leave it on for future use.

Google Chrome

Step 1: Open Chrome and click the Three-Dot Icon in the top-right corner.

Step 2: Scroll down and hover your mouse over More Tools. A sub-menu will appear — click Clear Browsing Data.

Step 3: A new window will open where you can toggle the time frame and decide to delete browsing history, cookies, and cache files. Adjust this accordingly and hit Clear Data.

Step 4: Choose which items to delete and hit the Clear Now button.

And that’s how you clear cache on all the major browsers for Safari. It’s a relatively simple process across the board, and doing this on occasion can greatly improve load times for your computer.

If you still feel like your computer is underperforming, there may be another issue to fix or it may be time to finally buy a new Mac.

Apple's first all-screen foldable MacBook has been rumored for many years, and it's finally getting closer. Reports from analyst Ming-Chi Kuo suggest Apple plans to release its first foldable as early as 2026.

According to Kuo, Apple is considering both 20.25-inch and 18.8-inch panels that, when folded, would equate to a 14- to 15-inch MacBook and a 13- to 14-inch MacBook. Previous reports estimated a 2027 release for these all-screen MacBooks, but Kuo's latest information suggests we could see them as early the first half of 2026. And now that Apple has introduced its M4 chip, it's little surprise that these future devices are expected to run on M5 series processors.

The laptop, equipped with a Snapdragon X Elite processor, put up impressive results across the board, but battery life stands out most.
