Save your data in iCloud

Store in iCloud option allows the users to save the data in the iCloud server. The simplest way to do it is to click the “Store in iCloud.” After this step you will get the window with several options:

  • Desktop and Documents. This option allows you to store your files from these directories in iCloud Drive. You will have access to them from all your devices anytime
  • Photos. This kind of data takes up a lot of space on your Mac for sure. Store your media in the original size and free up your Mac storage. In case you need these files – go to iCloud and open them
  • Messages. Sometimes these data are way important, and you can store them in iCloud along with the attachments. When you don’t have enough free space on your Mac, use this option to free up the storage

iCloud is a great option for those who want to free up space on MacBook without losing data. You get 5 GB of iCloud storage for free, but you can also change this size by selecting the tariff (starts from 50 GB for $0.99).


Optimize the Storage on your MacBook

MacBook has one interesting and useful feature by the name of Optimize Storage. In a few clicks and your storage will be cleaned up from unnecessary files. You can choose the preferred option among this list:


Automatically delete watched movies and TV Shows. You can optimize the work of your Mac by using this option and delete the media files from the iTunes Store that you don’t need anymore


Download only recent attachments. It doesn’t matter if you open an email or not, the recent attachments will be downloaded automatically


Don’t download attachments automatically. When you open an email the attachments will be downloaded.


IMPORTANT! You won’t use the iCloud storage by using Optimize Storage.

Reduce Clutter

Reduce Clutter can help you identify large files and files that are no longer needed. Click the Review Files button, then choose any sidebar’s file categories, such as Applications, Documents, Music Creation, or Trash.


You can delete certain categories of files directly from this window. Other categories show the total storage space used by files in each application. You can then open the app and decide whether to delete files from within it.

2. How to fix the Startup Disk Full on your MacBook?

Even the fastest and most powerful computers become clogged with unnecessary files over time, and Apple MacBooks are no exception. The most obvious way to fix this issue goes to checking the disk space and figuring out what you can delete and free up the storage.


If you don’t want to go through this process manually and alone, you are lucky because MacKeeper will help you fix the problem. You can easily free up the disk space on your MacBook in a few simple steps. Only you need to follow the steps provided by MacKeeper.

3. Remove unused apps and all their leftovers

macOS has several simple ways of deleting unused applications. The simplest option lies in dragging the app from the “Apps” section to the “Trash” bin directly. Another option is to use Launchpad, which removes the apps in a few clicks. And lastly, third-party apps can also do the job.

Deleting apps via Launchpad is more fun. Open Launchpad from your Dock. Now, press the Command key and hold any app icon until they start shaking. You will see the [X] symbol above the icon—click it to delete the application.

8. Clear your Desktop

Desktop may not seem a big deal in terms of storage. However, it’s a well-known fact that a messy desktop wastes tons of space—and most importantly—slows your Mac down.


If you are running macOS Mojave or Catalina, you can click anywhere in the middle of the Desktop and then select “Use Stacks” in the window that appears. Everything there will be neatly sorted by categories like Screenshots. Now you can delete all the thousands of screenshots that most of us have.
