Mac Clean Library

Optimized Storage in macOS Sierra and later* can save space by storing your content in iCloud and making it available on demand. When storage space is needed, files, photos, movies, email attachments, and other files that you seldom use are stored in iCloud automatically. Each file stays right where you last saved it, and downloads when you open it. Files that you’ve used recently remain on your Mac, along with optimized versions of your photos.

The Storage Management window offers recommendations for optimizing your storage. If some recommendations are already turned on, you will see fewer recommendations.


Store in iCloud

Click the Store in iCloud button, then choose from these options:

  • Desktop and Documents. Store all files from these two locations in iCloud Drive. When storage space is needed, only the files you recently opened are kept on your Mac, so that you can easily work offline. Files stored only in iCloud show a download icon , which you can double-click to download the original file. Learn more about this feature.
  • Photos. Store all original, full-resolution photos and videos in iCloud Photos. When storage space is needed, only space-saving (optimized) versions of photos are kept on your Mac. To download the original photo or video, just open it.
  • Messages. Store all messages and attachments in iCloud. When storage space is needed, only the messages and attachments you recently opened are kept on your Mac. Learn more about Messages in iCloud.

Storing files in iCloud uses the storage space in your iCloud storage plan. If you reach or exceed your iCloud storage limit, you can either buy more iCloud storage or make more iCloud storage available. iCloud storage starts at 50GB for $0.99 (USD) a month, and you can purchase additional storage directly from your Apple device. Learn more about prices in your region.

Optimize Storage

Click the Optimize button, then choose from these options.

  • Automatically remove watched movies and TV shows. When storage space is needed, movies or TV shows that you purchased from the iTunes Store and already watched are removed from your Mac. Click the download icon next to a movie or TV show to download it again.
  • Download only recent attachments. Mail automatically downloads only the attachments that you recently received. You can manually download any attachments at any time by opening the email or attachment, or saving the attachment to your Mac.

Other ways that macOS helps automatically save space

With macOS Sierra or later, your Mac automatically takes these additional steps to save storage space:

  • Detects duplicate downloads in Safari, keeping only the most recent version of the download
  • Reminds you to delete used app installers
  • Removes old fonts, languages, and dictionaries that aren't being used
  • Clears caches, logs, and other unnecessary data when storage space is needed

How to free up storage space manually

Even without using the Optimized Storage features of Sierra or later, you can take other steps to make more storage space available:

  • Music, movies, and other media can use a lot of storage space. Learn how to delete music, movies, and TV shows from your device.
  • Delete other files that you no longer need by moving them to the Trash, then emptying the Trash. The Downloads folder is good place to look for files that you might no longer need.
  • Move files to an external storage device.
  • Compress files.
  • Delete unneeded email: In the Mail app, choose Mailbox > Erase Junk Mail. If you no longer need the email in your Trash mailbox, choose Mailbox > Erase Deleted Items.

  • When you duplicate a file on an APFS-formatted volume, that file doesn't use additional storage space on the volume. Deleting a duplicate file frees up only the space required by any data you might have added to the duplicate. If you no longer need any copies of the file, you can recover all of the storage space by deleting both the duplicate and the original file.
  • If you're using a pro app and Optimize Mac Storage, learn how to make sure that your projects are always on your Mac and able to access their files.

Here’s a quick guide on how to clean junk files on Mac. We’ll go over types of junk you might have on your Mac and why it’s there, as well as ways of getting it removed. Why would you want it removed (apart from the desire to keep your Mac clean)? Because junk not only takes up space, it slows your Mac down, and it’s usually the reason behind system glitches and errors. In other words, getting rid of it is all around a great idea.

This guide will help you to clean all the extra junk on your Mac’s operating system and breathe new life into your Mac.

What are user cache files and how to remove them?

The user cache files are usually app files that are stored on your Mac. These are various temporary files that are meant to speed the performance of the Apple software. Caching data is essential for Macs that use wired internet connection. But, by caching for a long time, your Mac accumulates lots of files, which can affect its performance. So, it’s better to clean your Mac of them and help it run faster.

Here’s how to clean junk files on Mac and remove user cache:

  1. Open Finder.
  2. Press Command+Shift+G.
  3. Enter the following command into the field and select Go: ~/Library/Caches.
  4. In the window that appears, you will see all your cache files.
  5. Press Command+A to select all files and delete them. Press Command and click on the folders you want to delete if you don’t want to remove all files at once.
  6. In the pop-up that appears, you’ll need to enter your user name and password.

If you still see folders in Caches, maybe you have some windows open. In other cases, there will be no cache files left.

What are system log files and how to remove them?

Every Mac has system log files stored deep inside its memory. Mac saves and stores system log files mainly for developers to diagnose errors and problems with macOS and system applications when they occur. These logs are plain text files, so they usually don’t take up a lot of storage. But, when you’re running out of free space, deleting even such small files may help you declutter your Mac.

Mac Clean Library Caches

It’s important to note, though, that cleaning system log files manually, you may accidentally delete some essential data. So, make sure to back up your data to avoid heartache when you delete something important. Using safe cleaning tools notarized by Apple, like CleanMyMac X, can help you prevent the risks of removing valuable data.

So, to clean system junk on your Mac, do the following:

  1. Open Finder.
  2. From the Go menu, select Go to folder.
  3. Enter the /var/log in the field and select Go.
  4. You will see all the system log files. Select the files you want to remove and drag them to the Bin.

You can also find system log files in /Library/Logs. This folder contains system application logs that aren’t essential to store.
If you go to /Library/Logs/DiagnosticReports, you will find system reports. Safely delete the files to keep your Mac clean and free of clutter.

How to remove user log files?

When your app crashes, you usually are asked to submit a bug report. The system gathers your user logs and includes them in a report. The user log files don’t contain information on user activity as it may seem. They only deal with app-level functionality.

Mac Clear Library Cache

If your Mac is old, you probably have a lot of user logs. So, it’s time to clean your machine of them.

Follow the instructions to delete user log files on your Mac:

  1. Open Finder.
  2. Press Command+Shift+G.
  3. Enter the following command in the field and press Go:
    ~/Library/Logs.
  4. You will see all the system log files. You can manually move the files from folders to Bin.

If you want to declutter your Mac fully, select all user log files and delete them.

How to delete language files?

Mac Clean Itunes Library

Thanks to localization and language files, you can set your apps to the language you prefer. But once you determined the language of the app, you may delete other language files. These files are usually stored inside application packages, so many users don’t even have the faintest idea they exist on their Macs.

If you wonder how to delete junk files on Mac, you may start by removing the language files:

  1. Open Finder and go to the Applications folder.
  2. Right-click any application icon and select Show Package Contents.
  3. Find the Resources folder and open it.
  4. All subfolders ending with “lproj” are language files. Each folder contains localization information on a particular language. For example, the folder named en.lproj comprises English language files.
  5. Select the language folders and move them to Bin.

Don’t forget to empty the Bin, when you’re done removing junk files from your Mac.

How to remove Xcode junk?

If you use Xcode, tons of your disk space gets hogged with old cache and junk that Xcode consumes. You might not even notice it until it impacts your Mac’s performance. In case you would like to go over all the libraries to remove Xcode junk manually, here’s a list of paths you need:

~/Library/Developer/Xcode/DerivedData
~/Library/Developer/Xcode/Archives
~/Library/Developer/Xcode/iOS DeviceSupport
~/Library/Developer/CoreSimulator
~/Library/Caches/com.apple.dt.Xcode
~/Library/Application Support/MobileSync/Backup

Important notice: we do not assume responsibility for the possible damage or loss of data that might occur when you manually clean Xcode libraries. Thus, venture this path on your own risk. Or use CleanMyMac X, because it knows exactly how to clean Xcode cache, traces, and leftovers and does it neatly, leaving all the important files intact.

How to remove junk files on your Mac with CleanMyMac X?
