How do I create white fonts with black outline on iMac?

It can also be done in Apple's Pages and the particular font may lend itself to better effect. Here Helvetica Regular 13 pt is used with 200% enlargement.

I started with black text, selected it, and chose a white text color. While still selected, I clicked the more options text selector ⛭ and on that panel, clicked Outline. For the outline, I selected a solid 0.4 pt black line. You might consider adding + that text style to your Character Styles panel as shown below:

There are a number of ways depending on what you mean.

You can format text as Outline in apps such as TextEdit.

You can download outline fonts from the internet.

You can create your own outline fonts using a number of font editors such as FontForge, FontLab, etc.

What dialabrain said. You cannot create fonts on macOS, but you can either store the character style in a new Pages template for reuse or even download a free outline font and place it in your /Users/username/Library/Fonts folder.

I would have mentioned Pages but I got tired of typing. :)

Completely understand…😏

If you have the patience, can you explain how I could save this font?

FWIW, you can't actually save it as a font. Only as a style in Pages.
