Optimised Storage helps you save storage space by storing your content in iCloud and making it available on demand:
In this tutorial, we have told you how to clear cache on MacBook Air/Pro and other Mac computers. You can manually clear cache from system, app data and browsing history. Moreover, we also show the easiest way to clear all cache and temporary files on Mac with Mac Cleaner throughly. I found 1 solution to figure out how to clean up a little Other space, opening iTunes up, going to Preferences, Device and cleaning all the devices backups except the last one. Sure, it cleaned up 1 GB for me and 46 for my cousin, but the Other storage still takes a half of our Mac storage. I'll be glad for your answers and helpful comments.
- When storage space is needed, files, photos, films, email attachments and other files that you rarely use are stored in iCloud automatically.
- Each file stays exactly where you last saved it, and will download 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, find out about other ways to free up storage space.
Find out how much storage is available on your Mac
Choose Apple menu > About This Mac and 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.
Manage storage on your Mac
The Storage Management window offers recommendations for optimising your storage. If some recommendations have already been turned on, you will see fewer recommendations.
Store in iCloud
Click the Store in iCloud button and 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 work offline easily. Files only stored in iCloud will display a download icon , which you can double-click to download the original file. Find out 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. Find out 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 50 GB for $0.99 (USD) a month, and you can purchase additional storage directly from your Apple device. Find out more about the prices in your region.
Optimise Storage
Click the Optimise button to save space by automatically removing films and TV programmes you've watched. When storage space is needed, films or TV programmes that you've purchased from Apple and have already watched will be removed from your Mac. Click the download icon next to a film or TV programme to download it again.
Your Mac will also save space by only keeping recent email attachments on this Mac when storage space is needed. You can manually download any attachments at any time by opening the email or attachment, or saving the attachment to your Mac.
Optimising storage for films, TV programmes and email attachments doesn't require iCloud storage space.
Empty Bin Automatically
Empty Bin Automatically permanently deletes files that have been in the Bin for more than 30 days.
Reduce Clutter
Reduce Clutter helps you identify large files and files you may no longer need. Click the Review Files button and then choose any of the file categories in the sidebar, such as Applications, Documents, Music Creation or Bin.
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.
Find out how to re-download apps, music, films, TV programmes and books.
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 these settings directly within each app.
- If you're using macOS Catalina or later, choose Apple menu > System Preferences, click Apple ID, and then select iCloud in the sidebar: Store in iCloud turns on the Optimise Mac Storage setting on the right. To turn off iCloud Drive entirely, deselect iCloud Drive.
- If you're using macOS Mojave or earlier, choose Apple menu > System Preferences, click iCloud, then click Options next to iCloud Drive. Store in iCloud turns on the Desktop & Documents Folders and Optimise Mac Storage settings.
- In Photos, choose Photos > Preferences and then click iCloud. Store in iCloud selects iCloud Photos and Optimise Mac Storage.

- In you're using macOS Mojave or earlier, open iTunes, choose iTunes > Preferences from the menu bar, then click Advanced. Optimise Storage selects “Automatically delete watched films and TV programmes”.
- In Mail, choose Mail > Preferences from the menu bar and then click Accounts. In the Account Information section on the right, Optimise Storage sets the Download Attachments menu to either Recent or None.
Empty Bin Automatically: From the Finder, choose Finder > Preferences, then click Advanced. Empty Bin Automatically selects “Remove items from the Bin after 30 days”.
Other ways that macOS automatically helps to save space
With macOS Sierra or later, your Mac will take these additional steps automatically 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 described in this article, you can take other steps to make more storage space available:
- Music, films and other media can use a lot of storage space. Find out how to delete music, films and TV programmes from your device.
- Delete other files that you no longer need by moving them to the Bin, then emptying the Bin. The Downloads folder is good place to look for files that you may 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 Deleted Items mailbox, choose Mailbox > Erase Deleted Items.

- The Storage pane of About This Mac is the best way to determine the amount of storage space available on your Mac. Disk Utility and other apps may show storage categories, such as Not Mounted, VM, Recovery, Other Volumes, Free or Purgeable. Don't rely on these categories to understand how to free up storage space or how much storage space is available for your data.
- 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 only frees up the space required by any data that 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 Optimise Mac Storage, find out how to make sure your projects are always on your Mac and able to access their files.

How To Clean Memory On Macbook Air
Few things are more frustrating than your Mac telling you it has run out of memory when you're trying to be productive. It's more frustrating when you've ignored the problem for quite some time and your Mac's limitations simply won't let you put a solution on hold any longer.
- How to get rid of low memory notifications
Usually, a popup warning isn't the first sign that something is amiss. You may have noticed that your Mac isn't running as fast as it used to, with the fan louder than normal as if it's struggling to carry a heavy load up a hill.
Macbook Air Memory Full
Although Macs are wonderful computers, they have limitations. Thankfully, there is plenty you can do to resolve this problem and get your Mac operating smoothly again.
Reduce memory usage with Setapp
Instead of manually deleting files, get Setapp. It not only removes the clutter but also gives you full control over memory usage.
Your system has run out of application memory - Fix it
Mac memory usage is often occupied by apps, even browsers like Safari or Google Chrome. In the most dire circumstances, your Mac will toss a warning at you: 'your system has run out of application memory.'
Google chrome apple mac download. Don't despair – it's solvable. The first thing to note is this is a natural issue; your Mac has a limited amount of RAM. Though more expensive Macs have more RAM, even they can butt against limitations when too many applications are running.
It may also be an app that is hogging all of your resources. This is especially true of older applications which haven't been optimized for modern computer architecture. Websites may also be a culprit.
Check RAM usage on Mac
To check your RAM use on any Mac, take the following steps:
- Open Activity Monitor from your list of applications
Note: You can do this is the Mac's control center, via the Finder in your Mac's dock, or by pressing command-space and typing 'Activity Monitor' in the Spotlight search field. - Toggle to the 'Memory' pane in the Activity Monitor window
As you see in the above screenshot, Activity Monitor shows you all of your processes, sub-processes, and how much memory each is taking up. The most pertinent portion of the window is the bottom, where it shows you the total memory usage, and how it's affecting your Mac.
A better way to monitor your Mac's memory use is with iStat Menus. After installing the app, it makes a home in your Mac's menu bar, and monitors just about everything, including memory, CPU, GPU, disks, and network usage.
You can choose which systems you'd like to monitor in the app itself. Only the items you're monitoring will have an icon in your menu bar. A simple click on the menu bar icon surfaces a drop-down menu of how your Mac is performing at the time, and hovering over each graphic brings up a larger menu, as you can see below.
How to check CPU usage on Mac
Checking CPU use on your Mac is similar to the steps above for checking memory use. For Activity Monitor, you'd make sure to highlight the 'CPU' section of the window. This will show you all the processes using your Mac's CPU at the time.
Similarly, iStat Menus has a 'CPU & GPU' toggle just above the memory section. Activating that will add a CPU and GPU monitor to your Mac menu bar, which has the same interactivity as the memory icon and menu shown above.
How to free up memory on Mac
Knowing how to clear memory on Mac is important, especially if you have a Mac with limited resources. One option is using Activity Monitor:
- Open Activity Monitor on your Mac
- Select an app using a lot of memory
- Click the 'x' icon on the top left of the screen
This is straightforward, but there's a better way. CleanMyMac X has an automated CPU and memory monitors built-in, which can give you a real-time view of memory usage in your Mac's menu bar. It also has a really quick and easy way to free up memory without digging through Activity Monitor and manually shutting down apps.
All you have to do is click the CleanMyMac X icon, select 'Free Up' in the memory pane, and the app takes care of the rest! Oftentimes, it doesn't even shut apps down.
This is a quick fix, but CleanMyMac X takes it a step further in the app itself. Under the app's 'Maintenance' section is an option to 'Free Up RAM,' which helps you clear RAM on Mac. Once you've got this option selected, simply select 'Run' at the bottom of the window, and CleanMyMac X will do a thorough scrubbing of your Mac's RAM, and clear unused files out of the way.
How to get rid of low memory notifications
Most apps are pretty good about how they use your Mac's resources. Having too many open or running in the background can severely limit what your Mac can handle, and is often why a Mac overheats or slows down.
Here are a few tips to reduce high memory usage manually if you're experiencing unique warnings or issues:
Fix 'kernel_task', a high CPU usage bug
You may have noticed through Activity Monitor something called kernel_task absorbing a large amount of processing power. One of the functions of kernel_task is to help manage CPU temperature; you may find that your Mac fan is loud and always on, even if the device isn't hot to the touch.
kernel_task usually performs this way when one or more applications are trying to use too much CPU. Unfortunately, one of the potential downsides is a Mac can overheat to such an extent that internal systems are damaged, sometimes irreparably.
Working through the following steps in this article is one way to avoid similar problems. If none of this work and kernel_task is still absorbing a high percentage of your CPU, then one or more of the following could be the cause:
- Cooling system inefficiency
- A failed or disconnected temperature sensor
- Another hardware issue, including a worn out batter
- Your System Management Controller needs a rest
If you're experiencing severe issues, Apple recommends a system management controller (SMC) reset. It's essentially a hard reset for your Mac, and should help your RAM and other hardware components start from scratch. Keep in mind you won't lose any data in this process.
Reduce memory usage in Finder
One common culprit for RAM issues is Finder, your Mac's file manager. If iStat Menus or Activity Monitor has highlighted Finder as using hundreds of MBs of RAM, there is an easy solution: change the default display for a new Finder window so it doesn't show All My Files.
- Click on the Finder icon in the Dock and click on the Finder menu, then select Preferences
- Click on General. Under 'New Finder windows show', click the dropdown menu and choose any option except All My Files
- Close Preferences, press Alt-Control, and click on the Finder icon in the Dock. Click Relaunch
Finder will now relaunch with new windows opening at the option you selected in step two.
Improve Chrome's Task Manager
Chrome is a popular browser, but it's a resources hog! Chrome uses a GPU Process as standard, which means it speeds up the loading of web pages, which can be great except at times when your computer is struggling with insufficient RAM.
Here's how:
- Open Chrome on your Mac
- On the right side of the Chrome window, select the three-dot menu
- Select 'More tools'
- Select 'Task Manager'
- Select a Chrome process you'd like to kill
- Select 'End Process' at the bottom right of the window
Here's another way to reduce Chrome's use of your Mac's memory:
- Open Chrome on your Mac
- On the right side of the Chrome window, select the three-dot menu
- Select 'settings'
- Scroll to the bottom of the page and select 'advanced'
- Scroll down to 'System,' and toggle 'Use hardware acceleration when available' off
This will affect how Chrome runs on your Mac, and your experience won't be as smooth. You can also remove unused or unwanted Chrome extensions to help it use less resources on your Mac.
Get CMM X to free up space
Install CleanMyMac X and streamline the entire process of memory management on Mac. Clever memory usage control done for you.
Clean up browsers
In every browser you use regularly, there are always going to be extensions and popups that take up space and use RAM. You can manage each one manually, or use a tool such as CleanMyMac X to identify and delete them.
In the CleanMyMac X app is a section titled 'Extensions,' which lists each extension you have for your browser or browsers. All you have to do is view the list of extensions, select the ones you no longer want, and remove them. It's really that simple!
Disable login items
Login items, browser extensions, and preference panes, such as Flash, are another common source of memory usage. Most of us have several installed that we rarely use, but which hog memory and reduce performance.
One way to do this is through System Preferences:
- From your Mac menu bar, select 'System Preferences'
- Select 'Users & Groups'
- Select 'login items'
- Deselect items you no longer want active at login
Another way, one that is even quicker, is to employ CleanMyMac to identify and cleanup login items.
- Open CleanMyMac X
- Under 'Speed,' select 'Optimization'
- Select 'login items'
You can remove all login items, or select the ones you'd like to remove individually on the right side of the window.
Disable desktop widgets
Older Macs running a version of macOS older than Catalina can disable widgets. Desktop widgets can provide a useful shortcut to apps you need to access fairly often. But they can take up processing memory that is slowing your whole Mac down. One way to close them completely is in System Preferences.
Go to: Mission Control > switch off the Dashboard
Declutter your desktop
Apple's built in decluttering tool is handy for many. All you have to do on your cluttered desktop is right-click, then select 'Use Stacks.' This places all of your desktop files into folders unique to their filetype, like 'screenshots' and 'images.'
A better way is to use Spotless, an app that gives you far more control over how your Mac is organized. It has several triggers for automated cleanup of files on your desktop, placing them wherever you see fit. It's particularly useful for power users who produce several files daily, but don't want to take the time to place each in a respective folder.
You can also select many files on your Mac desktop, and tell Spotless to tidy them up. You always have full control!
Schedule regular cleanups
Constant use of your Mac, or leaving it on all the time, will slow it down over time. Shutting it down and restarting is a traditional way of 'cleaning up' a computer.
We also like CleanMyMac X's scheduled cleanup feature. Telling the app when you'd like to perform a thorough cleaning up of your Mac's system is a method many prefer to shutting down and restarting often. It has the upshot of removing files and folders you no longer use, and cleaning up tasks that are slowing your Mac down behind the scenes. A simple shutdown may not do this.
Keeping your Mac in tip-top shape is critical. While we'd all like to think computers are brilliant little devices that can handle anything, they need some care, too.
All of the apps mentioned in this article help with taking care of your Mac, and protecting your investment. Best of all they're each free as part of a seven day trial of Setapp. Give it a try today!
Meantime, prepare for all the awesome things you can do with Setapp.
