MacOS Monterey bug! - Mail signatures and smart mailboxes disappear from Mac Mail after reinstalling MacOS Monterey.

Thanks for visiting the Apple Support Communities, Alferatt,

To get started addressing the issue with your macOS Mail signature, we'd like to see if we can replicate the issue in two different scenarios, safe mode and a new user. Each will allow us to isolate and troubleshoot the issue, and may even resolve the issue completely on their own:

1. Start with safe mode using the guidance in How to use safe mode on your Mac - Apple Support. In addition to explaining how to boot your computer into safe mode, this resource will also explain in detail why it can be helpful. For example, safe mode runs a scan of your disk during startup, and if it identifies an issue tries to resolve it.
2. If the issue is present after safe mode, try a new user account: Set up users, guests, and groups on Mac - Apple Support. This can help isolate the issue by letting us know if it is occurring only in your user account. If so, this would mean the issue might be related to software or settings specific to your user account.

If you still need help after this, don't hesitate to respond back.

Best!

verbcrunch,

Here is a solution (at least its working so far) I got from an Apple Support chat yesterday:

Quit mail > go into System Settings > press (NAME) > click iCloud > click iCloud Drive > Options > scroll down until you see Mail > turn it off > add signature > quit Mail > open iCloud drive Options again > turn on Mail > Signature should stay.

Let us know if that works for you also.

I solved the "no signature" issue after noticing on some email accounts the signature still worked. So I deleted the no signature account from my mail app, then recreated it from scratch, works fine now.

Mac Mail is still really buggy in other ways though. I have to quit the app when mail becomes frozen - I can't click / drag / move the mail into different folders. Upon relaunch it's fine again for awhile.

Hi Alferatt,

Appreciate you trying the troubleshooting steps.

Since the issue still happens with another user, we'd advise to contact Apple Support, as what's happening isn't expected.

Take care!

Same thing. Updated new MacBook to Ventura OS and ever since Monterey OS on my iMac has this mail signature issue and is unable to synch Safari (eg bookmarks) between my iMac and MacBook. It should be noted here that my iMac is a late 2015 manufactured date and there are online indications that it will not update to the new Ventura OS. Will this be corrected Apple, or are you forcing everyone to buy new iMacs?

I'm having the same issue. Upgraded to Monterey and my logo image is not showing up in my email signature. Did troubleshooting from many sites and nothing fixes the issue. The email signature still works on my computers that I haven't upgraded to Monterey. Any solution to this yet?

Also, how in the world has Apple not addressed making email signatures easier on a Mac?! Unbelievably backwards.

I just bought an app from apple's App Store professing to help make email signatures easier. You basically just paste your HTML into it and it creates the file for you instead of you editing an email sig file yourself. Pretty worthless. The image still doesn't show using that either. The rest of the HTML display correctly, just the image won't show.

I installed Monterey on my 2018 MacBook when it became available and experienced NO Mail issues. I bought a new MacBook last week and can't get the signatures to save, no matter what I do. I've tried everything in this thread, and nothing works. I find it hard to believe that something so simple can't be fixed quickly, and also can't believe that I don't have this issue on my old MacBook but I do have it on my new one.

My problem is that when you sing-off from iCloud, all the signatures in all the accounts are erased to zero.

I am trying to recover them from Time Machine.

Once in a while you have to sign-off from iCloud because macOS Mail is slow in starting (20 seconds o open).

I have Ventura 13.1 on a new M1 macBook Pro 14".

Same thing: Loss of Signatures since upgrading to Monterey. BIG PROBLEM. Is there a SOLUTION?
