Why does my signature font change on Mac?

If the font you chose in MySignature.io is replaced by another typeface on your Mac, the selected font is likely not installed in Font Book on your macOS system. When a font is missing from Font Book, your Mac substitutes it with a default or alternative font from that font family.

How do I check and install the missing font in Font Book on Mac?

To verify whether your MySignature font is installed on your Mac and add it if needed, follow these steps:

  1. Open Font Book on your Mac by opening your Applications folder, selecting it from the Main Menu, or pressing Command + Spacebar and typing Font Book.

2. Type the name of your MySignature font into the Font Book search bar to check if it is installed.

3. Select All Fonts in the sidebar and confirm whether the exact font style appears in the list.

4. If the font does not appear in All Fonts or is substituted by a different style from the same font family, follow this guide on how to Install and validate fonts in Font Book on Mac.

Expected outcome: Once the font is installed and validated in Font Book, your Mac recognizes the typeface and displays your MySignature email signature using your chosen font.
