What are the benefits of deleting temporary files on a Mac?

When temp files and cache files get stored on a Mac, they take up a sizable chunk of space on the built-in storage, space that can be put to better use and that can help maintain optimal performance levels.

Depending on the number of internet based apps or software installed on your Mac, there will be different cache and temp files stored without your knowledge.

All these files can drastically slow down the Mac and you will notice a drop in storage space and performance. 

Temporary files vary from browser history, web image cache, passwords, form data, messages, and even incomplete downloads.

Once you get rid of all this unwanted data, your Mac will go back to performing tasks seamlessly.

What are the Potential Consequences of Deleting Temporary Files on a Mac?

While deleting temp files and cache will improve the speed of your Mac, there are some complications you should be aware of.

  • Deleting online website data and stored cache or cookies can log you out of the site. If you do not remember your password then you might not be able to login again.
  • Website load time may get affected when temp files or cached files are deleted. The pages will eventually load, but it will take more time as the website will have to download all the necessary files onto your Mac once again.
  • When cached or temp files are deleted, you will not receive any website recommendations auto populating in the URL bar of your browser. You will need to enter the complete website URL to access the site.
  • Site customization and personal preferences for each app or website will be wiped out and you will have to configure the app or website once again.
