How to free up disk space in macOS High Sierra

Recently, I was working on my MacBook Pro when I received an error stating that my SSD was out of place. “It can not be!” I thought (after thinking, I’m sure I said it loudly). The laptop in question was just a few months old and I had not saved or generated enough data to fill a 500 GB HD. So what does it look like? I opened Finder to dig, but curiously I did not find anything suspicious.

And yet, my record was full, which was a bit disconcerting, since I was rendering a video with Final Cut Pro. Would the rendering of the video be complete? Or would it be a mistake?

And then it started on me. Final Cut Pro always had all the projects I had done in the last few months. That must have been the problem. In this spirit, I began to recover this disk space which I needed so much.

How? With the help of the macOS storage manager. It’s a great built-in tool that lets you take control and recover storage space on your Mac. To make this tool even more attractive, it is incredibly easy to use.

MacOS High Sierra has updated the file system under the hood of the Mac, replacing the decades-old HFS + by the new APFS. What this means for the user is the much faster file copy, the ability to revert to previous versions of your documents, and several other cool features. But it also means that you have much less free space on your storage drive, thanks to the APFS habit of using it to store “dark matter”. Today, we will learn what is this dark matter, and how to free disk space.

Open the tool

First, you can use the storage manager in two ways. You can allow it to offer solutions on how to free up space, or you can use it manually. As a Linux user, I much prefer the manual method, which I will show you. For more information on using the automatic method, click here.

To access Storage Manager, click the Apple button (upper left corner of your desktop), and then click About This Mac. In the resulting window, click the Storage tab. In a few seconds, the storage space will be calculated and you are ready to work (Figure A).

Click the Manage button to reveal the heart of the tool. Here you can scroll through the recommendations or start manually deleting files. We will work with him. In the left pane (Figure B) you will see a list of file types and the available space in each category. The first thing to check is the Large Files tab.

Clearly, I have a number of Documents, 70 GB of documents on a hard drive? If I click on this category, the truth is revealed (Figure C).

Once again, video files are the culprit – the most important being a Final Cut Pro backup file. If I want to erase this space assuming I’m done with these files or have backups, I can select a file and delete it permanently (Figure D).

To select all the files, if necessary, click on the upper entry, hold down the Shift key and click on the lower entry. To delete all these files, select them, right-click (or double-tap) the selected files, and then click Delete. When prompted, click Delete and all of these files will be permanently deleted from your player.

Once you have cleared the Large Files tab, you can go through the Downloads tab and the File Explorer to complete the cleanup job. Chances are, however, to go through the Big File tab will have the desired results and you will have recovered hard disk space if needed.

It is ver easy

And that’s all there is to recover space on macOS. I hope you will not receive the warning I made, but if you use a tool like Final Cut Pro, your hard drive will fill up very quickly. In this case, it is essential to be able to easily recover the storage space.
