Are you getting an error message saying, “Your start-up disk is full?” Or, maybe your MacBook isn’t functioning properly and is rather slow? All such similar errors can be due to almost full system storage.

Thus, if you want to avoid full storage capacity, it’s best to clean up your storage regularly. But, what is it and how do you clear it? Read on to know how you can clear System Storage on your MacBook.
