If your computer gives you the full hard disk error, you should visit the nearest hardware store and buy an external drive. There are many solutions to this, but one of the most efficient answers is getting an external hard disk (preferably SSD) and transferring your files there. All of them are useful, and there's no telling when you might need something that seems useless right now. Some of us can't dream of parting with any of our files.

Just open the Applications folder in Finder and drag it to the Trash in the bottom right corner of the Dock. If you have video games you've finished or apps you never use, you can delete them while in safe mode. You can also delete apps you no longer need. If, for example, you have videos left over from a completed project or pictures you no longer need, you can delete them to clear up some disk space. Now that you're in safe mode, you should find large files in Finder that you no longer use. But we have a dedicated guide with information on how to boot your Mac in safe mode. Booting in safe mode varies depending on what processor your Mac uses. It's a good troubleshooting mode you can use for this full disk error. Safe mode is a boot mode on Mac that suspends all third-party software, leaving macOS with only the bare minimum it needs to run. However, if the error message keeps preventing you from doing so, you should boot your computer in safe mode. This should be relatively easy to do without any hassle. You first need to create space by deleting large files you no longer have any use for.
