ThelifeYou should clear your Mac's cache periodically to optimize its performance.
- When you clear your Mac computer's cached data, you're deleting the temporary media files, like images and text files, that it gathers from the sites you visit.
- Those files help reduce internet data usage and speed software installation on your Mac. But it's important to clear your cache periodically because it can help protect your identity and make your computer's applications run more efficiently.
- Luckily, it's easy to get those cached files deleted from your Mac (even if your shortcut buttons aren't working). Here's how.
You may have heard that it's important to clear the cache on your various electronic devices every once in a while. But what exactly is caching, and why do our devices use it?
Cached data consists of the various temporary files that exist on a reserved area of your computer. According to Apple, cached data on your Mac computer speeds up the downloading of Apple software as well as the data users store in iCloud by "saving content that local Mac computers, iOS devices, and Apple TV devices have already downloaded," and cached data is "available for other devices to retrieve without going out over the Internet."
Caching is especially important if your Mac is set up with wired ethernet, rather than relying on Wifi. And you'll get the best performance out of it when it's connected to your network using Gigabit Ethernet, according to Apple.
But as long as your Mac is set up to cache, that data needs to be cleared periodically to make your computer run more efficiently. That's because clearing your cache can help protect your identity, make apps run better on your computer, and prevent you from using outdated forms that your Mac collected when you first visited a site.
