What's Cache on Mac?

Cached data is automatically generated while you visit a site, open an application or browse the internet for viewing pictures and watching videos. Cache on the Mac system refers to the temporary files that your Mac computer downloads and stores to save time in the future.

Usually, we're dealing with three types of Mac caches, which are browser cache, operating system cache and apps cache.

Three Types of Cache Files on Mac

With stored cache data on Mac, no matter you're opening a Safari/Google/Firefox browser or booting up your Mac, it saves a great time because the cached data holds a copy of the history information of your earlier activities. Cache data helps accelerate load times of the operating system, browser and applications. However, too many cache files have some disadvantages, too. 

First of all, it takes up huge disk space; second, cache files prevent you from viewing the most up-to-date pages; at last, cache files on public computers have potential security issues. These are reasons why we need to clear cache periodically, or even immediately.

How to Recover Deleted Cache Files on Mac

  • Recover deleted browser cache files
  • Recover deleted system file caches

There are two scenarios of deleting necessary caches on Mac in the wrong way. One is browser cache files that contain history records, bookmarks or passwords, and the other is about system files caches that contain scripts, images, logs, temporary files, user account data and startup disk information.

Generally, browser caches won't do damage to your Mac operating system. As it may store some very important personal records of your work and study, we need a full recovery after accidental deletion. On the contrary, some system caches can be vital enough to ensure a normal startup, or the display of a regular font style, it can be impossible to bring it to the working state.

In a word, if you deleted cache files in browsers like Safari or Google Chrome, it's likely to perform a recovery from a synced iCloud backup, or the recent Time Machine backup manually.
