It’s staggering how much space can in fact be occupied by app/user cache on Mac. To make it even worse, undeleted cache data also leads to task conflicts and other system issues. What was initially useful becomes a drag, slowing down your Mac through all the wasted space it is taking up. Old cache files that remain latent in the system do nothing but piling up, cluttering your system folders. The outdated cache may be the reason why some websites behave laggy. For example, if the website you’re about to visit has been updated ever since your Mac cached its data, your browser will still load the outdated cached version of the site. Why should you clear cache on Mac?Ĭache is meant to help your Mac load sites faster, but sometimes it brings more harm than good. Cache files serve a vital function as they contain a “shortcut” to a task in order to perform it faster the next time. Cache is basically a technical data that is stored when an app, browser or system performs a task.
