How to restore default fonts for Apple Mail display?
I inadvertently changed the default font for Apple Mail while testing out making an email signature. I can't find the original, default font. Might have seen "system font" but cannot find it to restore. I hate the way my mail displays with any of the few font options I now see. Even Helvetica is hard to read. I am not comfortable using Terminal. Using Big Sur.
How can I reset Apple Mail to default settings especially the fonts?
TIA
