There are several good reasons to clear the cache on your Mac. It can help protect your privacy by removing stored personal data, fix misbehaving applications that aren't working properly, and free up valuable storage space. A clogged cache could also be the reason your Mac is running more slowly than expected.
Your Mac has two types of cache: application cache and system cache. The former contains data that has been generated and saved by your apps to speed up their processes, but they can become clogged with unnecessary files. Sometimes, when uninstalling apps, the cache remains — again, leading to a fair amount of waste being left behind. Clearing this cache can make sense.
