Part 4. Benefits of Clearing Cache

There are many benefits when you delete Mac cache.

First and foremost, it frees up the computer's storage space to a great extent. The cache files will occupy a large space, especially when you have run your computer for a long time. Clearing these files will spare more space for other important files and data.

Second, it can improve system performance. The accumulation of cache files will put pressure on the system responding system, thus slowing down the responding speed when we initiate programs. What's worse, it may influence the operation of the whole system, which will cause your computer to delay or crash. Therefore, you can speed up the running slow Mac by clearing the cache.

Next, clearing the cache may sometimes help you solve some operation problems due to the expired cache. If the application is updated, the old cache may no longer be applicable. So you need to clear the old cache in time. The cache starts to build up again as soon as you resume browsing.

Last but not least, it can protect our security and privacy on Mac. There may be some personal information, such as browsing history records and login credentials, in cache files. Removing them will protect our privacy and security in case of others get the data.
