Is your Mac running out of storage space? It happens -- especially if you've purchased a laptop with a smaller internal drive. 

When you find yourself in such a situation, what do you do? You could try clearing your browser data, but that won't always get back much space.

Also: I rescued my dying 2017 MacBook Pro with Ubuntu and it works like a charm (mostly)

Fortunately, there are things you can do to clear up considerable space. I've had instances where I've regained nearly 30 GB, which makes a huge difference.

That said, let's get to the different ways you can clear system data on MacOS.

How to clear system data on MacOS  

Clear system cache

The system cache is where you'll reclaim the most storage (especially if you've been using your Mac for a while).

Clear system logs

The next step is to clear system logs, which can also take up more space than you might think. Here's how this is done.

1. Open Finder

Once again, open Finder, click Go, and select Go to Folder. 

2. Navigate to log

In the resulting pop-up, type /var/log/ and hit Enter.

3. Delete it all

Select all the files inside the Log folder (Command+A), right-click (or two-finger tap) one of the files, and then click "Move to Trash." In order for the action to complete, you will be prompted for your user password. Type the password (or user biometrics), and the files will be sent to Trash. Make sure to empty the trash to delete everything.

Remove unused language files

If you've added extra language files and no longer use them, you can repeat a similar action by going to /Library/Languages and deletingonlythe language folders you don't need.

Uninstall unused apps

Finally, you can reclaim a bit more space by going to the Applications folder and deleting the apps you no longer use.

After you've taken care of the steps above, you should have reclaimed a good amount of internal storage space on your Mac.
