When you know how to set default apps on Mac, you can customize your computing experience to you, making it more efficient and enjoyable.

By setting custom default apps you can, for example, set all .JPEG files to open in one of the best photo editing software applications, like Adobe Photoshop.

This will come in extremely handy if you're regularly opening the same file formats as part of a workflow, or if you just particularly dislike the app used by macOS originally.

Better yet, it's easy to do. So read on to find out how to set default apps on Mac.

Note: this guide is for changing the default apps that open specific file types. If you're looking to change your default browser on Mac, read our guide on how to change default browser.
