Apple Mail automatically changes font size while typing, Part 2

So, it has been a year-and-a-half since I originally posted the following question and the problem still persists today. A Google search didn't turn anything up, and I'm hoping someone will see this and have a solution.

Here is the original message:

I've been using Apple Mail for about a month now and only just recently did it start exhibiting this unusual behavior where the font type and size of the entire message would change to something different while I was typing! Pressing CTRL+Z a couple times would revert the font to its intended size only to have it change back again a few keystrokes later. I noticed that it only happens when I type a word that contains an apostrophe (it's, David's, we're, isn't, we'll, etc.) and words that get auto-corrected. Going to MAIL | PREFERENCES and changing my Message Font does nothing as the font changes to something not set in Preferences.

I made a short video of myself typing an email so you get an idea of what I'm experiencing -- you can view the video here: https://youtu.be/2mYb9L5ZzDA.

Has anybody experienced this before? What did you do to fix it? Any help and suggestions are greatly appreciated!

It has to do with the autocorrect. I've seen this when I use a shortcut expander in a web browser. Uncheck your preference for color and see if this goes away.

If no, try setting up a test account or use Guest, see if the problem's global, or just related to your account.

CREATE A NEW USER

Go to System Preferences --> Create a New User in Users & Groups.

Switch to the New User by logging out/in or use Fast User Switching.

You can skip signing in with your Apple ID unless you need to test iCloud Mail.

Turn off spell check

I have check spelling turned off. I like the red squiggly lines so I can correct spelling myself. Autocorrect often puts in the wrong word.

Hi, Diane!

Thank you so much for replying and providing a possible solution. Unfortunately, this solution did not work for me 😟 However, your suggestion did lead me on the right path to finding the solution (after some trial and error, and after turning various features and options on and off): the culprit turned out to be my custom signature! I'm baffled by it myself, but after deleting my signature, and re-adding it (not cut & paste, but a completely new sig), the problem was fixed!

Thank you for taking the time to reply 🙂

Glad you found the fix.

Signatures can also cause problems when you accidentally start typing into the signature field. Your text font and size will take the Sig settings.
