What icons can be changed?
Unfortunately, not all application icons can be changed, as it is only allowed with third-party icons. In fact, some of these have an option already integrated in their settings to be able to change it for some other proposal from the developers, although not in most of them. In any case, native applications do not support changing the icon or at least not with the methods that we are going to explain, although it is possible to change the one for the folders.
Where to change icons in macOS
There is no section within the Mac settings that allows you to change the icons of several applications and folders at the same time. Therefore you will have to go one by one changing it, but it is extremely easy if you follow these steps:
- Copy a photo that you have saved on your Mac, either your own or downloaded from the internet. We recommend that you open it with a preview, and go to Edit in the toolbar and click on «Copy».
- Go to the place where the folder or application that you want to customize is located and secondary click on its icon and click on “Get information”. If it is an application you will have to go to the Applications folder, since from the dock it will not work.
- Select the application or folder icon that appears at the top of the pop-up window and press cmd + v to stick it.
- Now enter the Mac administrator password to allow the changes to be made.
Why are the changes not showing in the Dock?
If you have correctly changed the icon and you do not appreciate the changes in the dock or some other part, the advice we make to solve it is to remove it from this part, restart the Mac and put that icon back where you had it before. That way you will check that the changes made have already been applied.
Two recommendations for the images to use
Although you can use all kinds of images for the icons, whether or not they are square, it is recommended that they have that aspect so that they are strange and go against the aesthetics of the Mac. It is also recommended that they be in .PNG format and have a transparent background , in such a way that if it has a white background it is not visible in the icon and it is ugly.
What other icons can be put?
If there is already an icon in an existing application or folder that you want to reuse in another application, you can do that too. To do this, you must click on “Get information” of the original icon you want to have, copy said icon with cmd + c and follow the same steps as explained above to paste it into the other application that you want to take its form.
Return to original icon
If you want to restore the original item that was previously in the application, you will have to click on “Obtain information” in the application or folder you want to restore, select the icon at the top of the window and press cmd + x to cut it. It will not be necessary after you paste it anywhere, since that will already serve you to have eliminated the new icon that you had put.
