With new Macs out and the software upgrades, one of the cool things is that you can in fact install new fonts from Apple or third-party sources to enhance the user interface to befit your own taste but if you’re wondering how to go about this, then this short guide will help you out.

But before going further, a little on Mac Fonts. First of all, the Font Book is located right under The Application menu on the computer and the list includes system fonts which have been downloaded and can be installed if you want.

Because fonts are listed out based on Computers or Users, the ones you manually installed from third-party sources might not be listed on this page.

Going further, the fonts are arranged by collections which includes Fun, Modern, PDF and Traditional. Then you can add new collections to the Font Book but do note that this does not affect how the font works across macOS and in apps. The ability to add new collections is for organization use only.

How to install and validate fonts on Mac

The first thing is to install and then validate your Font through the Font Book and after this, the next validation process will be automatic. In case of problems, there should be a message letting you know what the problem is. And one common problem could be the fact that you installed the same app more than once which would require Apple’s prompt letting you know you should remove the duplicate in order to proceed to the validation.

With so many font libraries all over the internet some of which works quite well on Mac, other do not always work as planned and this can be annoying. But as stated, ensure to understand the problem when prompted via the Font Book in order to understand ways by which you can deal with whatever error being prompted.
