What is cache
Cache files are temporary files that are stored on a computer’s disk space and reused when needed in order to provide a faster and more efficient performance of the system.
There are different categories of cache files:
- browser cache
- system cache
- user cache
For instance, when you visit a website, the multimedia content, such as images and video, are being stored automatically on your MaсBook. Consequently, the next time you visit this website, the cached files are re-used for faster performance. A similar process occurs when you use software on macOS. Some supporting files are stored on the disk and re-used to provide proper function for a Mac.
Сache files are helpful temporary files. However, over time, they can be unnecessary and may take up too much space on your MacBook disk. Therefore, you should periodically clear the cache on your MacBook. We will share two methods on how to clear them: manually and via special Mac cleaning software.
Is it safe to delete cache files on Mac?
Clearing cache on Mac is safe if you follow some important steps before attempting it. First, quit applications and close running processes before you clear their cache. This will prevent any issues. Also, if you are working with some files or using any app, save your important data before closing the app and clearing its cached files.
You can safely remove the remaining caches and other service files of the applications you have already uninstalled.
If you decide to clear cache manually, make sure to be accurate with the folders inside the Library. You need to understand what files you are removing. We recommend that you use special software, for example, MacCleaner Pro, which does this work safely and with just two clicks.
Why delete cache on Mac?
Generally, it is not always necessary to clear system and application cache. Cache files are needed to make the system load faster. However, clearing cache data on your Mac can sometimes be helpful in improving its performance and freeing up storage space.
You should periodically clear system cache files and user cache files. Here’s why to delete cache on Mac:
- If the number of cached files increases greatly and takes up too much space on your disk, your Mac may start running slowly.
- Separate application cache files take up a small amount of space, but altogether they could require hundreds of megabytes. When your disk is full, clearing the cache is the first must-do step to free up space on it.
- If you remove applications on Mac by just dragging and dropping them into the Trash, their caches, now entirely useless, remain on your disk.
- Over time, some cache files might become corrupted and affect the stability of the software.
- Old caches load outdated content on web pages.
- You should remove caches and cookies if you want to delete your personal data stored by websites and applications.

How to manually clear system and user caches on MacBook
Every browser provides an option to clear its cached data. Things change when it comes to other applications’ caches and system caches. System caches are related to the daily operations of your macOS. By default, Apple stores all Mac caches’s cached files in the Caches folder in the Library. We will explain how to find this folder and clear the caches of particular applications inside this folder. Follow these steps:
- Quit all running applications on your Mac.
- Open Finder → go to the Finder menu → select Go → Go to Folder.
- Type ~/Library/Caches in the window currently displayed and click Go.
- Here, in the Cache folder, find the folders related to a specific application and remove files inside to the Trash.
Please note that it is better to remove cache files in each folder rather than the cache folders themselves, in order to avoid any errors. You have to go to the folders one by one and remove caches of the appropriate applications. Also, you must be very careful not to remove system cache folders (those which have the com.apple words in the names.)
