Cached data refers to the temporary files that have been created and used to fulfil various processes on your device. As a matter of course, such files are preserved. For example, when Safari loads images on a webpage, it will retain them as cache data so that the next time you visit the webpage, you won’t need to download them again — leading to better loading speeds.
While this can be useful, over time cache data can accumulate until it accounts for a sizeable chunk of memory. With that in mind, it’s a good idea to clear your cache now and then. Doing so is completely safe — cache data is by definition not necessary. That said, if in doubt regarding frequently used apps, make an external backup.
How to Clear Cache on Mac
- In the Finder toolbar, select Go > Go to Folder.
- In the search box, enter ~/Library/Caches and press Go.
- You will now be in the cache folder.
- Simply Move to Trash what you don’t need, e.g., system and app cache.
- If you want to clear everything, click Edit and Select All, beforehand.
- Following this, you’ll want to empty the Trash.
For DNS cache:
- Open Terminal via Spotlight.
- In Terminal, enter sudo dscacheutil -flushcache; sudo killall -HUP mDNSResponder and press Enter.
- Type your password and click Enter again to complete the command.
