Have you ever wondered why your Mac is running slow? Does it freeze when performing even just the simplest of tasks? Does it take a while to launch and switch programs? Everybody has gone through this excruciating pain at least once.

Even though the Mac is known to be a high-performance machine, it disappoints us sometimes as it slows down over time. There are numerous reasons why this happens. The main reason is a full hard disk. The more available space your Mac’s hard disk has, the more efficient your Mac will operate.

You may ask why your hard disk runs low on space. One of the culprits could be your hard disk cache has become loaded with unnecessary files.

What is Cache?

Yes, it is safe. That said, don't just delete all the contents of your cache folder without reason. It can be beneficial to clear out those taking up the significant space in your /Library/Caches/ if you need to free some up, but you really shouldn't clear any contents of your /System/Caches unless there is a problem.

Cache files are data saved by browsers, systems and applications on your hard disk to guarantee a smooth user experience. It is mostly used to speed up processes.

For instance, Safari will load images on a webpage and downloaded them to the cache so that the next time you visit the website, you don’t need to download them again because they can be retrieved from the cache. This reduces the wait time to load webpages.

As time goes by, the number of cache files increase considerably. Even though they are temporary and can be deleted, most people don’t bother to do so. In turn, these cache files start to take up storage space resulting in lowered system performance.

Cache files include system cache, app cache, browser cache, library cache and more.

Although other operating systems store cache in different file locations, the Mac OS stores cache files in the cache folder.

How Does Cache Affect Your Mac?

Although the primary purpose of cache is to provide a smoother user experience, the constant build up of data leads to storage space issues on a Mac.

Cache files are small in size, however going a long period of time without cleaning the hard disk means that these cache files can increase to gigabytes in size, resulting in a system with a minimum of disk space to operate. It affects the smooth performance in which Mac computers are known for.

To avoid this from happening, it is recommended to clear your cache regularly.

How to Clear the Cache on your Mac Manually?

Mac systems are harder to clean compared to other operating systems as the destination is located within other folders and files. With the lack of knowledge on how to clean a Mac, the most inevitable question asked is: How to clear the cache on Mac?

Many people prefer opting for the longer route and cleaning the cache themselves. There are several types of cache files and each file is stored in different locations and cleared differently.

Here’s how different types of cache files can be cleared manually on your Mac:

User Cache:

User cache takes up the most space on your hard disk which is normally located in the User Cache folder “~/Library/Caches.”

Although a good cleaner locates and clears cache files well, manual deletion requires more work.

Reminder: User cache also includes sensitive data. Some users may encounter errors opening the files and system applications after clearing it entirely. It is recommended to perform a backup first.

To create a backup:

• Select “Go to Folder” in the Go menu of a File folder

• Type “~/Library/Caches” and press Enter

• Select all using ‘Ctrl+A’ and copy all folders and files

• Go back to Library and create a new folder ‘User Cache’

• Copy all data to the new folder

To remove user cache:

• Select “Go to Folder” in the Go menu of a File folder

• Type “~/Library/Caches” and hit Enter

• Go into each of the folders and delete every file

We recommend that you remove the files inside the folder, not the folder itself

After you have deleted all cache from the original location, you may delete the created backup as well.

System Cache and App Cache:

System cache is composed of files stored by system applications that run in the background of a Mac.

App cache consists of media files downloaded by the applications in order to speed it up, as well as system thumbnails, temporary downloads, and so on. Although useful, app cache takes up significant space over time and needs to be cleared.

What Are Caches On Mac

To remove system and app cache:

• Type “~/Library/Caches” and remove the data inside of the folders with the app name.

One important thing is that not all app cache is safe to be cleaned. Applications are designed to keep essential data in some of the cache folders. To avoid mishaps, backing up cache data before cleaning is always a safe option.

In order to make sure no harm is done, you may delete the backup after some time.

DNS Cache:

The DNS cache is a type of system cache. These are old cache entries that translate internet domain names (e.g., drcleaner.com) into IP addresses on your Mac. Regularly clearing DNS cache ensures an uninterrupted connection to websites.

To clean the DNS cache:

For older Mac OS versions (before OS X 10.10.0):

• Open Terminal via Spotlight.

• Type into Terminal:

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

• Enter admin password to complete.

For latest MAC OS versions (Mac OS X 10.10.0 and above):

• Open Terminal via Spotlight.

•Type into Terminal:

“sudo discoveryutil mdnsflushcache; sudo discoveryutil udnsflushcaches; say flushed”

• Enter your admin password to execute.

Browser Cache:

Internet browsing is the most commonly known activity on a device as well as a major source of income for many. While we browse from site to site, all activities result in a growing cache.

Browser cache consists of website data such as images, scripts, and so on, in order to speed up your browsing experience. It allows you to visit the same website faster with the use of the stored cache on the computer.

Aside from freeing space on your hard disk, clearing the browser cache accomplishes multiple purposes. It can secure privacy by deleting the browsing history. It can also potentially help to get rid of known errors such as error 404, 502, and so on, often caused by a corrupted cache.

Each browser stores cache differently, meaning, the process of clearing cache differs across browsers. As for the most commonly used browsers, Chrome’s cache location is in ‘Settings’, Safari stores it in ‘Privacy’, while Firefox’s location is under the History tab.

To Clear the Browser Cache:

For Chrome:

• Click the options icon at the top right corner of the Google Chrome browser

• Choose Settings

Your Mac has a secret. Thousands of them in fact, in the form of hidden files and folders lurking on its hard drive or SSD. Don’t worry, though. These files and folders are all supposed to be there. In fact, many of them are essential.

Many of these files are in your Mac’s main Library folder or in the ~/Library folder, which is in your User folder. Both these Library folders are hidden, but inside them are folders and files that hold things like preferences for apps.

In this article, we’ll tell you how you can view hidden files on your Mac and make your Library folder visible.

What are the hidden files on Mac?

The hidden files are a throwback to macOS’ Unix roots. In fact, the convention of naming them starting with a “.” comes from Unix. For that reason, you can’t use a “.” at the start of a regular file name, otherwise OS X will hide it.

The files themselves contain data like access rights and privileges for files and folders, application support files, and preferences.

There are a number of reasons files and folders are hidden. Mostly, though, it’s because they contain data critical to the smooth running of your Mac and that you shouldn’t interfere with. In addition, there’s no real reason for most users to see or access them. Also, if they were all visible, your Mac would look horribly cluttered.

How to view hidden files on Mac

Before you make your Mac show hidden files, it’s important to remember they’ve been hidden for a reason. The data they contain could cause havoc if you delete or alter it and don’t know what you’re doing.

If your goal in viewing, for example ~/Library is so you can manually delete application support files for a program you’ve uninstalled, consider using a dedicated uninstaller like CleanMyMac X. That will make it easy to remove all the files associated with an application with one click. You can download CleanMyMac X for free here.

CleanMyMac X will also allow you to get rid of all the hidden files you no longer need. Many of these files are created and used then not needed anymore. They just sit there clogging up your hard drive. CleanMyMac X scans your Mac, identifies this system junk and allows you to quickly and easily get rid of it, potentially several gigabytes of disk space.

If you still want to view hidden files on your Mac, you need to go to the Finder and do the following:

1. Open a new Finder window and click on the name of your Mac under ‘Devices’ in the sidebar.
2. Click on Macintosh HD, or whatever you’ve called your startup drive if you’ve renamed it.
3. Press Command-Shift-. (period). You should now see lots of files and folders who’s name starts with “.” become visible.
4. To re-hide the files and folders, hold down Command-Shift-. again.

How to view your Mac’s ~/Library folder

There are a couple of methods for making your ~/Library folder visible. Here’s the simplest:

1. Click on the Finder in the Dock.
2. Open a new Finder window and navigate to your user folder (Tip: if it’s not in the sidebar, go to the Finder menu, choose Preferences, click Sidebar and check the box next to your Home folder)
3. Click on the Go menu.
4. Hold down the Option (Alt) key.
5. You should see that in the dropdown menu, Library appears below Home. Click on it.

Alternatively, do this to view your Library folder:

1. Click on the Finder in the Dock.
2. Click on the Go menu and choose Go to Folder.
3. In the window that opens, type “~/Library”

With both these methods, your Library folder will disappear again when you close the Finder window. It’s easy enough to run through the steps above again to make it visible again when you need to, but if you want it permanently accessible, there are a couple of ways to do it.

The quickest is to drag the Library folder to the Finder’s sidebar. That will create a shortcut to it that will persist. If you want to keep ~/Library visible but don’t want it clogging up the sidebar in Finder windows, do this:

1. Click on the Finder in the Dock.
2. Click on the View menu and choose Show View Options.
3. Check the box labelled Show Library Folder at the bottom of the window.

How to make macOS show hidden files using Terminal

If you’re feeling particularly adventurous, you can use the Terminal command line interface to view hidden files and folders. Here’s how to do it:

1. Open Terminal from the Utilities folder in Applications, or by searching for it using Spotlight. You can also use the Go menu in the Finder to go directly to the Utilities folder.
2. Type, or copy and paste, this command: defaults write com.apple.Finder AppleShowAllFiles true
3. Press Return
4. Type: killall Finder

To hide the files again, repeat the above steps, but replace ‘true’ with ‘false’ at the end of step 2.

How to hide any file or folder using Terminal

Now that you know how to view hidden files and folders on your Mac, you may be wondering how you can hide other files or folders, to keep them away from prying eyes. There are a number of third-party applications and utilities that offer to do this for you, but you can do it yourself in Terminal, like this:

1. Launch Terminal.
2. Type: chflags hidden
3. Press the spacebar.
4. Drag the file or folder you want to hide from the Finder onto the Terminal window.
5. You’ll see the path to the file or folder displayed in Terminal after the command you typed.
6. Hit Return to execute the command.

The file or folder you dragged onto the Terminal window will now be hidden. To see it again, use one of the methods described above to see hidden files.

To make the file visible permanently again, use the steps above, but in step 2 type: chflags nohidden

As you can see, viewing hidden files and folders on your Mac is very straightforward. There are a number of ways to do it, and you can make them visible temporarily or permanently.

However, just because you can view hidden files, doesn’t mean you should — the files are usually hidden because accidentally deleting them or altering them could cause chaos on your Mac. So, while it’s fine to have a peek, don’t do anything with the hidden files unless you know what you’re doing.

If you want to declutter your Mac or uninstall applications, use a dedicated application like CleanMyMac X. It will safely remove all useless files, add-ons, broken login items, caches, large and old files you didn't know about. Most likely, you won't even need to look for hidden files — CleanMyMac will do all the job for you.

We also showed that many of those files are stored in Library folders, including the one in your User folder, ~/Library. That folder is hidden by default, but you can view it or make it permanently visible using the techniques described above.
