How to Remove or Clean Caches on Mac OSX

Summary: This post focuses on the techniques that can be used to clean Mac OS X caches. Stellar SpeedUp Mac has been suggested as the safest way to do it.

To surf the Internet in high-speed, having a fast connection is not the only thing you need. Often, even after investing in a lightning quick connection, users complain that web pages on their Mac OS X open too slowly. Online speed tests stating that their Internet connection is indeed yielding high data access speeds offer little assurance. In such cases, your Mac browser’s sluggish behavior may seem odd, however, it can be easily fixed as what your browser needs is a good clean Cache.

Let’s look at how.

OS X Cache Problems

Before jumping to the fixes here’s a little something on Mac caches. OS X supports 3 main types of caches, viz. system cache, browser cache, and user cache. The system cache includes app cache and DNS cache. Cache files typically store information about your browsing history such as text and pictures to quicken the page loading when you visit the same pages again. However, over time, cache files start piling up within your Mac’s hard drive, therefore, consuming considerable space.  This could have been otherwise used for other system purposes. This often leads to degraded performance of your browser and eventually of the entire Mac.

Nothing gives the Mac a power boost like a nice sweep of the hard drive. Cleaning up large unused files, getting rid of unwanted applications, and wiping the desktop of unnecessary files can go a long way in boosting up your machine’s performance. While cleaning up large unused files, you should pay attention to deleting browser caches too. These files serve the sole purpose of recording information and thus, they can be deleted without affecting any other system behavior.

Let’s look at how we can remove caches on Mac instantly.

Easy ways to clean Mac caches

There are 2 basic ways to clean caches on Mac: manually and automatically through third-party tool.

Manual cache clearing

To clear all 3 types of Mac caches manually, follow the steps below:

For user and system cache:

  1. Navigate to Finder -> Go menu -> Go to Folder
  2. Type ~/Library/Caches and press Enter
  3. Go into each folder and delete everything. DO NOT delete the folders, only their contents
  4. Repeat the above steps, but substitute ~/Library/Caches with /Library/Caches
  5. Empty the Trash
  6. Restart Mac

The above steps can also be used to clean up app caches. App cache files contain information that helps apps run faster by not loading saved information again and again. If you can afford to do away with app cache files, delete them as shown above by clearing out the contents of app folders. However, proceed with caution as to not delete the necessary files. We suggest relying on automatic third-party tool recommended later.

For browser cache:

Follow the steps below:

Note: They differ as per browser-type.

Chrome ->    1. Open a new Chrome window and click on the ‘more’ icon (3 vertical dots)                       in the top right corner

  1. Go to History -> History -> Clear Browsing Data
  2. Select only “Cached images and files”
  3. From the time drop-down, select “the beginning of time”
  4. Click on the button that says “Clear browsing data”

Firefox ->      1. Open a new Firefox window

  1. Go to History -> Clear Recent History
  2. From the time drop-down select “Everything”
  3. Click on the down arrow next to Details and select only “Cache”
  4. Click on the button that says “Clear Now”

Safari ->       1. Choose Safari from the top menu

  1. Go to Preferences -> Advanced Tab
  2. Enable Show Develop Menu in Menu bar
  3. Now in Menu bar, go to Develop -> Empty Caches

After clearing the caches manually, make sure you quit all the browser windows and restart the browser for the changes to take effect.

For DNS cache:

Clearing DNS cache helps remove old cache entries that translate domain names into IP addresses thus making sure all websites work correctly. Follow the steps below:

  1. Open Spotlight and type Terminal
  2. Press Enter
  3. In Terminal, type the command

sudo discoveryutil mdnsflushcache;sudo discoveryutil udnsflushcaches;say flushed

  1. When prompted enter the admin password. For OS X 10.10.4 and later, the above command should be changed to:

sudo dscacheutil -flushcache;sudo killall -HUP mDNSResponder;say cache flushed

 

Automatic cache clearing
