How to stop macOS Monterey from auto-correcting Name to all CAPS?

So this was driving me bat**** crazy. I tried messing with keyboard settings etc.

I ended up fixing two things.

1. My contact card had been all capitalized. I changed to Firstname Lastname
2. (This one had me going) I emailed someone my contact info with my name in ALL CAPS. Siri was finding that email, adding it as a hint in my contact card and "correcting" my name. After I deleted that email, it cleaned up my contact card. Mail stopped putting my name in ALL CAPS.

Look in your contact card and see if Siri is adding hints. If she is, delete them.

I just started having this problem today, though maybe it's been going for a few days since I don't type my full name every day. I am certain the problem wasn’t occurring a few weeks ago, as I can see in Mail that I wrote some emails in late February in which I included my full name.

Last week I updated to Sonoma 14.4 from whatever the previous version of Sonoma was, so I wonder if that's a factor, though I can see from this discussion, and some others I found online, that other people have had this problem with older versions of macOS.

I have Apple Care + coverage still so I called Apple today and they are working on figuring out a solution. I also I haven't seen any posts by people saying they've talked to Apple support about this problem. If Apple does figure out a solution , I'll post it here.

But it's really frustrating that there's no way to train macOS to stop capitalizing one's name.

Using bayard's post as a lcue, check...

Mail>Window>Previous Recipients, highlight the ones you don't want & click the Remove from list button.

Just a quick update: all of a sudden, the problem has gone away. It may start happening again but right now it's gone. I have no idea what caused the change.

I have the same problem with Sonoma 14.5 on MacBook Pro M1Max

The solutions posted don't work.

How do I fix this Apple glitch???

Suggest checking in the Contacts application on how Exactly your Profile name is appearing

Is it all Capitals ?

I've got the same problem. Annoying and haven't been able to find a fix.

Is this a Laptop?

No, I'm using an M1 Max Mac Studio running macOS Sonoma 14.4.

I'm at a loss as to the cause. :(
