When I make tutorials, sometimes my Mac says I have 10GB left in my storage. There were some ‘hidden’ files I could not get rid of. After a lot of research I found an amazing tool called OmniDiskSweeper that helps you to find and delete those ‘hidden’ files. The first time I tried that tool I could delete 250 GB of files I could not find on my computer. So I want to share this so you can also clean up your Mac computer!
