If you ever felt like you’d like to customise and change the standard icons of any app, file, or folder on macOS, but you didn’t know how, you’ve come to the right place. It’s actually very easy, and can be done in just a few very simple steps.

You first need to find and download an icon of your choice. I recommend the site IconArchive, they have many high-quality icons. There are a few different icon formats available on the site, but the one you need for Mac is the .icns format. If you’ve got a retina display, I suggest you filter for Large Icons.

Once its downloaded, place the .icns file on your desktop, or anywhere easily accessible.

Let’s Begin

As an example, let’s say you’d like to change the default icon of your Macintosh HD.

Normally, the icon looks like this:

And you want to change it to this one, by Robsonbillponte:

New Drive Icon

Just click once on the drive until it’s highlighted, like this:

Highlight HD
Select the HD

Then, press cmd(⌘) + i on your keyboard. This will open the Info panel, like so:

Finally, you can take your new icon and just just drag and drop it over the default icon at the top of the Info panel.

macOS will often prompt you for a password to make the change, so just enter your password, press Enter and voilà, your icon will be changed. Simple.

You can do this with pretty much any file, folder or app across macOS.

Reverting Back

Should you want to revert back to the original icon, it’s also very easy. Just open up the Info panel again, click the icon at the top, and press the delete key on your keyboard.

Boom, job done!
