Mac login name font name looks wrong

Might be a third party font issue ...

Open the Font Book located in your Applications folder.

Then go to the Font Book menu bar and click Edit > Look for Enabled Duplicates

If there are no duplicates found, back to the Font Book menu bar, click File > Restore Standard Fonts

Fonts not included in the OS X system install will be placed in a "Fonts (Removed) folder next to the Fonts folder.

Here's another fairly simple one.

Close all running applications. From an administrator account, open the Terminal app and enter the following command. You can also copy/paste it from here into the Terminal window:

sudo atsutil databases -remove

Terminal will then ask for your admin password. As you type, it will not show anything, so be sure to enter it correctly.

This command removes all font cache files. Both for the system and the current logged in user account. After running the command, close Terminal and immediately restart your Mac.

Since the caches won't be rebuilt until after the Mac is coming back to the desktop, you may not see any difference the first time. So once at the desktop, restart again to check.

The command Carolyn had you try removes any third party fonts from the three main Fonts folders that may have been causing the problem. However, do either of these apply?

1) Have you removed any OS supplied fonts?

2) Are you using your font manager (whether Font Book or any third party option) to automatically enable third party fonts "in place" on each startup?

"In place" means the fonts are activated from wherever they reside. So they can still be activated even if not in one of the three main Fonts folders. Since they are not any of those three folders, the Font Book command Restore Standard Fonts won't do anything to disable them.

If you disable & enable specific fonts then : Open font book via spotlight , & click all fonts . Click the name of the font in the font column & choose disable font name family from the edit menu .

Fonts that have been disabled have their names displayed in grey with the word OFF appearing next to the fonts name .

So , If you 'd like to enable a font that was previously disabled , click the name of the font from the fonts column , then take your cursor on top menu bar & click on edit , choose font having OFF in front of it , choose enable font family .

Note : System fonts can't be disabled .

I'm having the same problem. Did you by any chance use Onyx to clean out your system? I only noticed the issue after I ran a clean using the Sierra version of Onyx.

Edit: I actually just tried the Font Book suggestions above and it fixed it. Maybe a combination of the two did it.

It is something that happens within the User visual area - the tech has only seen it twice before and has been with Apple quite a long time.

Wow. There's one to write down for future reference. I wonder who figured out such a rare and seemingly unrelated trigger for a problem to begin with?

Thank you very much for sharing that. It will eventually help other users who find this topic searching for the same solution.

Confirmed that this worked for me too. Thank you for calling Apple and thank you for posting the solution! You should mark this as the answer.
