Your files on your Mac are more valuable than the computer itself!

Agree or not, I always tell my friends and colleagues that: “If you love your Mac, make sure to regularly back up the data and check hard drive health.”

After all, your Mac drive’s performance can make or break your overall computing experience.

Today we’ll be talking about another common issue: finding and removing duplicate files on Mac.

If you’re like me who has an older Mac, chances are your Mac’s internal drive is almost filled up. A full hard drive will not only slow down Mac startup but affect your work productivity due to more frequent Mac freezing times.

One of the culprits — duplicate files (also called duplicates) can take a surprising amount of disk space on your Mac.

In particular, if you are used to syncing and backing up all your iPhone and iPad data on your Mac, it’s inevitable that duplicate files will stack up.

Below, we are going to share with you a number of different ways on how to find those duplicate files and by removing them you could free up a decent amount of disk space.

Why Remove Duplicate Files on Mac?

  • Free up additional space so you can save more precious photos.
  • Find your wanted items more quickly.
  • Improve the overall performance of your machine.
  • Make more Time Machine backups and be less worried about data loss.
  • Other potential benefits.

How to Find and Remove Duplicates on Mac

Final Words

Duplicate files on Mac can be a bit annoying, but it’s often inevitable. Taking our smartphones or digital cameras for example, we are used to making several shots in a row in order to get the best one. But we often forget to clean up the duplicated or not-so-great photos. At the end of the day, our iPhones and Mac hard drives can be easily filled up with those identical or similar pictures. Thankfully, there are some time-efficient ways to find those duplicates either with Apple’s built-in features or via third-party apps.

One thing to remember though, when you are about to remove those found duplicates — think twice and make sure you don’t delete the wrong ones as the action may be irreversible. Also, do not try to remove any duplicate files in macOS system folders, most of the time you can’t do so because they are read-only. But in case you may have modified certain permission settings.

Anyway, we hope you find this article useful. Let us know which methods or apps work best for you.
