Does your MacBook start sounding like a rocket ship that’s about to take off if you have more than four browser tabs open at once? If so then you may want to do a cleanup of your Mac’s disk space and there’s no better way to do it than through a third-party app called Disk Inventory X.
The app, which I first learned about from Joanna Stern’s excellent guide to improving your old Mac’s performance, gives you an easy-to-understand breakdown of the files on your Mac that are clogging up your storage. When I first used it, for instance, I found that there was a mystery folder that I never used that was taking up a ton of space. On closer inspection, it turned out the folder contained an entire copy of OS X Snow Leopard that I had never bothered to get rid of — no, don’t ask me how it got there because I don’t know either.
What makes the app particularly useful is that after it scans your disk, it gives you a list of folders on your Mac that are taking up the most storage. In my case, I found a huge folder of old pictures I’d taken at the 2013 Mobile World Congress that I had absolutely no need for. I deleted them and freed up at least 1GB of space through that alone.
At any rate, if your Mac sounds like it’s wheezing through its last breaths, give this app a shot and see if it can boost your computer’s performance.
