Methods to clean up Mac cache include: 1. Delete the system cache, access the /Library/Caches and ~/Library/Caches folders and clear the content; 2. Clean the Safari browser cache, and operate through the privacy tag or development menu in the preferences; 3. Manually delete the application cache folder or use the application's own functions; 4. Incorrectly deleted files can be automatically generated and restored or restored from backups. It is recommended to skip uncertain files.
It is actually not difficult to clean the cache on your Mac. The key is to know where to clear and how to operate. When many users find that the computer is slowing down or the application is running abnormally, cleaning up the cache is a simple and effective solution. The following methods are suitable for most cases and can be done without installing additional tools.

Where is the system cache file and how to delete it
There are two main locations for system cache: one is system-level /Library/Caches
, and the other is user-level ~/Library/Caches
. These two folders usually store temporary data generated by Safari browser, App Store downloads, and other applications.

To access these folders:
- Open Finder
- Click "Go to" > "Go to Folder" in the top menu bar
- Input path:
/Library/Caches
or~/Library/Caches
- Just delete the contents (be careful not to delete the wrong folder)
It should be noted that some cache files cannot be deleted when they are in use, so you can restart and try to clean them.

How to handle Safari browser cache
If you are using Safari browser, its cache and cookies are managed separately. The cleaning steps are as follows:
- Open Safari
- Click "Safari" > "Preferences" in the top menu bar
- Switch to the Privacy tab
- Click "Remove All" to clear cache and website data
- You can also select "Clear Cache" in the "Development" menu (if there is no development menu, you can turn it on in Preferences > Advanced)
After doing this, the web page loading may slow down a bit because the browser needs to re-download resources, but it can effectively solve some problems of abnormal web page display.
Whether to clear the application cache, how to find it
Many applications will also save cached data locally, such as WeChat, QQ, Chrome, Photoshop, etc. This type of cache is usually in the ~/Library/Caches
directory, and each application will have an independent folder.
Common practices are:
- Enter
~/Library/Caches
- Find the folder corresponding to the app you want to clean, such as
com.tencent.xinWeChat
orGoogle/Chrome
- Just delete the files inside
Some applications also come with a clearing function, such as Chrome can directly "clear browsing data" in settings.
What to do if you delete something else accidentally
There are some configuration files or logs outside the cache folder. If you accidentally delete other content, don't worry too much. In most cases, the system or application will automatically generate missing files the next time it is started. If an exception occurs, you can try reinstalling the relevant software or recovering from the backup.
In addition, if you are not sure whether a file can be deleted, it is best to check it first or skip it to avoid affecting system stability.
Basically all this is it, it is not complicated to operate, but it is easy to ignore details. If you encounter lag or loading exceptions, you might as well try to manually clean the cache to see if there is any improvement.
