the macOS system font is fixed... from OS X El Capitan to current Sonoma is San Francisco

"San Francisco is an Apple designed typeface that provides a consistent,

legible, and friendly typographic voice. Across all Apple products, the

size-specific outlines and dynamic tracking ensure optimal legibility at

every point size and screen resolution."

you can submit your Apple Feedback here: Product Feedback - Apple

for application specific, see the app settings to make changes—

If you mean the main font used in the GUI, you don't.
