One thing that’s as sure as death and taxes, is the fact that your Mac’s hard disk will eventually fill up. These days it may be an SSD or Fusion Drive, but regardless of the nature of the hardware, it can hold a finite number of gigabytes, and the more files you add – whether new apps, downloads, music, and videos, your photo collection, work files or anything else – the less space will be left. And the same goes for your iPhone or iPad.
As we so often say about macOS and iOS, remember there’s only a problem when there’s a problem. There’s generally no need to worry about unwanted files existing, or to install software that promises to remove them. They won’t break anything or slow anything down. But when you try to save or download a file and get a warning that your drive is almost full, yep, you’ll need to do something about it.
In this article, we look at all the kinds of content that are likely to be taking up storage unnecessarily, where to find them and how to get rid of them safely. Finally, in case it feels like time for more drastic action, you’ll see how to wipe your drive and start again.
Step one: Identify space hogs and optimise storage
The bigger the file, the more you’ll gain by trashing it
Your Mac’s built-in primary drive, called Macintosh HD by default, is where all your files are stored unless you saved them to an external drive. Check both for anything you don’t need to keep.
