I created handwriting worksheets in the Pages app. Worked flawlessly even though during installation it said there was an issue. I just ignored and installed anyway. Installation of the fonts was a breeze. The one recommendation I have is to add the dotted version of the letters to this font for tracing purposes. I like that you just hit the space bar to create the lined/dotted paper without any letters. Additionally, a Getty-Dubay font would be a great offering separately (There are people all over the internet looking for GD font that works well with newer Macs.)
10 Block Letter Fonts to create worksheets and exercises conforming to the D'Nealian method. This way of teaching handwriting can be better because it does not require as many lifting the pencil from paper, and it facilitates transition from block letters to cursive, as letterforms are much closer. See each font, play with it and activate it immediately to use with any Macintosh application. This package is very easy to use because once the fonts are activated, you simply use your favorite program to create your own exercises, with your own phrases and curiculum. Letters can be printed in color, as well as very big, for posters and cards to show the whole class, as well as banners. Many teachers use these fonts to print pupil names on stickers, for back to school. The font files can be saved from the app. Retina support, macOS Sierra supported.
