Pros and Cons of Cache Clearing

A cache is a small storage unit that keeps small data packets for various sites. When you are opening new sites during online sessions, the browser gathers and stores specific Internet data packets to the cache. The cached files stay in the cache and help users to have an efficient browsing experience. If you use a Mac, smartphone, or laptop, your devices will always have some data in the cache library.

The cache unit is an essential component that allows the browser to fetch data faster without any downtime. The browser doesn’t have to locate the site’s server afresh when your device already has cached data. Thus, caching is a necessary process that also helps faster browsing and device efficiency.

However, the memory cache can get filled with these temporary files. After using your device for an extended period, your cache might have redundant or corrupt files of no use for you anymore. Therefore, it is advisable to clean it up regularly to free up hard disk space and keep your Mac in stellar condition.

Cache clearing allows your machine to perform optimally without any problems due to inadequate disk capacity. You can open any website and launch your apps without any errors.

What Cache to Monitor?

Therefore, before we delve into the pros and cons of cache clearing, it is imperative to understand where the cache has a significant impact on a computer system:

Hardware and Software

The primary purpose of the CPU is to process data through the software in a particular device. Thus, the cache is both in the hardware and software components. For instance, smartphones and laptops have their cache units and each software application in the device.

Web Browsers

You can use various browsers today – From Safari to Chrome, among others. These browsers often store the cached data of the sites you frequently visit. Each browser has its set of cache units. Some of the files include cookies, HTML file extensions, images, and JavaScript.

For instance, when you shop online on a particular site, the cache will store the images of the products you viewed and other Internet scripts used to load the pages on your next browsing session. That is why clearing browser cache and history will delete all the stored information, and you will have to load the pages afresh.


Computer applications also have cache units that store essential files. Since all apps are different, the cached files will also vary. Some of the cached data in apps are images, search engine history, among other essential thumbnails.

Even though cached data are vital in giving users an unmatched online experience, it also has some downsides, especially when left for an extended period. That is why you must practice regular cache clearing to free up space in the memory cache.

To Clear or Not to Clear?

In contrast, cache clearing also has its advantages and disadvantages.


The cache is a small storage location that stores temporary files, as mentioned above. It allows faster loading and browsing without having to wait for sites to open. When you are a frequent Internet user, your cache might be filled up quickly. However, after an extended period, the cache might experience file overload and cause the system to underperform.

Thus, you must clear the cache to restore your system to optimum performance.

Here are some benefits of clearing cache from your Mac:

  • Enhances Performance: The primary reason for cache clearing is to enhance your system’s performance. When you visit new websites frequently, the browser files are stored in the cache for use in the next session. Over time, you might notice reduced performance or web pages might refuse to open. Thus, clearing cached data ensures your system runs smoothly without any errors or downtimes.
  • Prevents Security Threats: Cybercriminals are getting more sophisticated with advancing technology. Many hackers can use cached data to infiltrate private networks. They embed malware or virus links to the stored files and use the loophole to attack unsuspecting users. Therefore, cache clearing mitigates such online risks and protects your system from security breaches.
  • Loads New Pages: Sometimes you might visit a previous site, but the browser takes you back to the old web pages when you open it. Thus, clearing cache allows the browser to load updated pages that the old files could not. It enhances your browsing experience since you will be viewing new pages from the website’s server.
  • Fixes Browser and App Errors: When you have cached files in your system over an extended period, chances of getting application and browser errors are high. You might be browsing, and the website takes longer than usual, or your application refuses to launch. Old or corrupt cached files might be the reason why you are experiencing such errors.  Therefore, clear your cache regularly to avoid browser errors.
  • Ensures Smoother User Experience: Since clearing cached files will improve the general performance of your Mac, you will also enjoy a seamless browsing experience. Frequent cache deletion is a vital exercise that leaves your Mac in good condition.


As much as cache clearing is an important exercise, it also has its downsides. Let us take a look at some of the common disadvantages:

  • Slow Loading of Websites: Clearing cache deletes all stored files that enhance faster browsing. When you go back to open a previous web page, the browser will have to connect with the website’s server afresh. Therefore, you might have to wait longer to access the websites, causing a cumbersome online experience.
  • Loss of Information Details: If you are used to visiting sites with your saved login information, you might have to key in your details afresh. Clearing cache wipes all the stored data files in your laptop or smartphone. This might cause productivity issues and delays if your machine is for work-related tasks.
  • No Target Advertising: Many online companies use cookies and cache to lure customers into purchasing their products or services. Companies that rely on targeted advertising might lose out if the users practice regular cache clearing. Thus, the cleared cache will also wipe out the tracking cookies and compromise their marketing strategy.
  • Not Much Free Space: Deleting cache is not a solution if you want to get additional space in your hard drive. Though it helps in improving performance, the cache unit is not that huge. Therefore, do not rely on cleaning temporary files as a primary method for disk space extension.

Pay Proper Attention to Your Cache

As we have mentioned, caching plays a vital role in enhancing user experience, it can get harmful if left on your system. Cybercriminals might take advantage and use old cached data to embed malware into your system.

Finally, deleting cache might seem optional to many Mac owners, but it has its consequences if ignored. You might encounter issues and delays in processing specific tasks. Moreover, you might not browse efficiently due to corrupt files stored in the system. To avoid such inconveniences, IT experts advise users to practice regular cache clearing. Though there is no specific time to conduct the exercise, you can set your schedule. Don’t wait for the cache to experience overload or for the applications to get corrupt.

Therefore, keep your system safe by clearing cached data. If you are busy, get a cleaner app to help you in clearing the files automatically.
