Changing Default Text Size for Messages and Signature (macOS)

Problem

The user wants to change the default font size for composing emails and for the email signature in Airmail on macOS, but online guides do not match the current version of the app.

Solution

In Airmail for macOS:

• Go to Airmail Preferences → Appearance → Font Size and Preview to adjust the default font size for reading emails.
• For the composer font, go to Preferences → Composer → Default Composer settings.
• To change the signature font, go to Settings → Signatures, select the signature, and use the formatting toolbar to adjust font size.

Note: After macOS updates, some settings locations may shift. If the settings don't match your version, try searching within Airmail Preferences.
