Apr 15, 2011 Tip: Change Mail settings to save hard drive space. While working with a client today, I uncovered a handy tip that could save you an extremely large amount of hard-drive space on your Mac. Six months have passed since this problem started for me (following the Outlook update 14.2 in April), so I decided to try Outlook again now with all updates, but my MacBook Proâs CPU usage immediately raced up again. So I will just continue to use Apple Mail, which works fine (despite slightly lower functionality than Outlook).
Having to play around with large video files can be a headache when my system has a blazingly fast SSD drive but is only 500GB in size. Going to the macOS storage analyzer can be a mixed bag of easy to understand actions to reduce disk usage to cryptic descriptions that are more daunting to deal with.
We have spoken about how to rid your computer from data noted in 'other' which in short is space taken up by caches, plug-ins, and documents. But now we'll show you how to reclaim some of your disk space from your 'System' disk usage.
Mail App On Macos Uses Alot Of Memory Windows 10Time Machine and local backups
If you run Time Machine for backups over Wi-Fi like I do, then macOS High Sierra will simultaneous use your remote backup disk and your local disk to save backups to. The reasoning behind this is that in the event the remote backup disk is not available or present, then you can recover files in spite of a missing remote backup disk and recover from the local disk.
In fact, macOS High Sierra manages this disk usage seamlessly without user intervention. It also purges local backups if disk space starts to get too low. However, sometimes the purging doesn't happen to leave enough disk storage for my very large video files and I'll get a 'not enough disk space' message. And instead of waiting for macOS to catch up with my disk space requirements, I can force the purging from the terminal.
Determining if you have a large amount of 'System' disk usage
Free software for making beats on mac. To see if this method will help you reclaim some disk space we need to check the macOS System Information.
In my case, 'System' (meaning the operating system) was clearly using the most space. Although I understand the reasoning behind why Time Machine is storing local backups, I didn't feel that I needed so much of my disk space devoted to these local backup snapshots.
If you have other categories that have very high disk usage you can click the manage button to get more details on what is using that disk space and possibly delete those things that you determine to no longer have use for.
Purging local backups
Please note that although this doesn't affect your remote backup from Time Machine, this will get rid of the redundancy (at least until the next Time Machine backup) that a local backup disk will provide. If you need such redundancy or are worried about the recovery of your data then you would be best served to let macOS determine when to purge these files.
Here, you'll now see a list of all of the locally stored Time Machine backup snapshots stored on your disk.
Next you can remove the snapshots based on their date. I prefer to delete them one at at time. Once my 'System' disk usage is at an acceptable level, I stop deleting but you can delete all of them if you want to reclaim all of the disk space.
You can watch your System Information graphic free up disk space in real time to see if you've removed enough.

I want to stress that this should only likely be used if you absolutely immediately need to reclaim the disk space. Otherwise macOS does a pretty good job in managing the unused disk space for local backups and purging when it deems necessary.

This timelapse of macOS 10.0 through 10.15 is a nostalgic wonder
The very first version of macOS, or Mac OS X as it was known, arrived almost 20 years ago. This video takes us through every major update the Mac has seen since in one amazing timelapse.
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 youâve used recently remain on your Mac, along with optimized 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. Each segment of the bar is an estimate of the storage space used by a category of files. Move your pointer over each segment for more detail.
Click the Manage button to open the Storage Management window, pictured below. This button is available only in macOS Sierra or later.

Click the Store in iCloud button, then choose from these options:
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.
Optimizing storage for movies, TV shows, and email attachments doesn't require iCloud storage space.

Empty Trash Automatically permanently deletes files that have been in the Trash for more than 30 days.
Reduce Clutter
Reduce Clutter helps you to identify large files and files you might no longer need. Click the Review Files button, then choose any of the file categories in the sidebar, such as Applications, Documents, Music Creation, or Trash.
You can delete the files in some categories directly from this window. Other categories show the total storage space used by the files in each app. You can then open the app and decide whether to delete files from within it.

Where to find the settings for each feature
The button for each recommendation in the Storage Management window affects one or more settings in other apps. You can also control those settings directly within each app.
Empty Trash Automatically: From the Finder, choose Finder > Preferences, then click Advanced. Empty Trash Automatically selects âRemove items from the Trash after 30 days.â
Other ways that macOS helps automatically save space
With macOS Sierra or later, your Mac automatically takes these additional steps to save storage space:
