Dec 07, 2017 The Mac I was using at the time reported that all the disk had been consumed, despite every attempt I made to prune/delete/tidy up docker containers and the issue persisted across reboots.

Oct 07, 2019 How to free up storage space on your Mac Save space by storing your content in iCloud or using built-in tools to find and remove large or unneeded files. Optimized Storage in macOS Sierra and later. can save space by storing your content in iCloud and making it available on demand.

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, films, 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 optimised versions of your photos.

* If you haven't yet upgraded to macOS Sierra or later, learn about other ways to free up storage space.

Find out how much storage is available on your Mac

Choose Apple menu  > About This Mac, then click Storage. This is an overview of available storage space on your Mac, as well as the space used by different categories of files:

Click the Manage button to open the Storage Management window, pictured below. (The Manage button is available only in macOS Sierra or later.)

Manage storage on your Mac

The Storage Management window offers recommendations for optimising 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 (optimised) 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.

Optimise Storage

Click the Optimise button, then choose from these options.

• Automatically remove watched films and TV shows. When storage space is needed, films 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 film 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.
  
• Don't automatically download attachments. Mail downloads an attachment only when you open the email or attachment, or save the attachment to your Mac.

Optimising storage for films, TV shows and email attachments doesn't require iCloud storage space.

Apple used to provide the SVN command line client with XCode (it still might) but it never provided the JavaHL library or any of the language bindings, so it is best to get Subversion from a package manager. I use and recommend Homebrew. If you are doing software development on OSX, having this installed will make it easy for you to get a lot. Under Mac OS X I find a link to OpenCollabNet but I can't find binaries on that link, would much appreciate if someone could help me locate the link to binaries. And also is there a way to install Subversion JavaHL library via macports, if yes what is the command to do so. My Understanding - Basically, svn client comes by default on Mac os. While installing in eclipse we should match svn plugin to the mac plugin and javaHL wont be missing. There is a lengthy process to update by installing xcode and then by using homebrew or macports which you can find after googling but if you are in hurry use simply the steps. Javahl library 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 Optimised Storage features of Sierra or later, you can take other steps to make more storage space available:

• Music, films and other media can use a lot of storage space. Learn how to delete music, films 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.
