How can I delete iPhone Mirroring on my iMac?

You can not delete native macOS app's.

If your iMac and/or iPhone are not compatible, just ignore and do not open the iPhone Mirroring app.

If you need to Stop iPhone Mirroring and/or Disable Notifications,

see > iPhone Mirroring: Use your iPhone from your Mac - Apple Support

On your iPhone > go to Settings > Airplay & Continuity > iPhone Mirroring > delete your iMac from the list.

Then you should be able reset your Mac's Lock Screen "Require password........." setting to Never.

I had the same issue. You need to make changes in the iPhone Mirroring settings as I have stated earlier to get rid of the grayed out menu. Review this in the iPhone mirroring settings section:

Thanks, I appreciate your answer but the reason I want it off is because every time the computer goes to sleep you have to sign in again, and that is very annoying.

What is your setting at  > System Settings > Lock Screen > Require Password after screen saver begins?

Do the following:

Open iPhone mirroring app

Open settings (top menu pulldown)

Check on "ask every time" (not the auto authorization)

This will stop you from having to enter PW all the time when waking or after screen saver

If that does not work then shut down your iPhone completely and your Mac then start both.

If it is grayed out, then you will first need to follow the steps provided by thirdvet:

Open iPhone mirroring app

Open settings (top menu pulldown)

Check on "ask every time" (not the auto authorization)

Then the option at  > System Settings > Lock Screen > Require Password after screen saver begins, will not be greyed out and you can change it to any value you want.

Are you able to access the Settings option in the iPhone Mirroring menu even if you see a message that it is not supported?

I was specifically talking about the Mac.

 > System Settings > Lock Screen > Require Password after screen saver begins, can be set to Never if you do not want to be required to enter a passcode.

This will be greyed out if on your Mac the iPhone Mirroring app is set to Automatically Authenticate. This is in the Settings of the iPhone Mirroring menu when the app is open. You said that you get a message that says the app is not compatible with your Mac, so I was asking if you are still able to access the Settings even when that message is on your screen.

The iPhone Mirroring app is only compatible with Macs that have the T2 chips and the only model I know of that will accept Sequoia and does not have a T2 chip is the 2019 iMac, which may be the one you have. I don't have that model, so I can't confirm if you are able to access the Settings of the iPhone Mirroring app.

I am not sure what model iPhone you have but my iPhone is the 13 and that is not in Airplay&Continuity, but I appreciate your trying to help.

I have the opposite problem as you. My Mac is compatible with iPhone Mirroring, but my iPhone 8 is not.

Thank you but the iPhone mirroring app on the Mac won't open because it says it's not supported on this model Mac yet it is there in all the apps and it won't go away, that is the problem. Because it won't go away I am forced to sign in every time the screen sleeps.

You need to follow the tbirdvet's instructions on you Mac and turn it off or disable iPhone Mirroring in you iPhone settings.

When you access the Settings on the iPhone Mirroring app on the Mac, are you able to change it to "Ask Every Time"?

I would suggest contacting Apple directly in case it is an oversight on their part that affects that specific Mac model that does not have a T2 chip, but can still install Sequoia.

Contact Apple for support and service - Apple Support

these things are not stuff that use up much storage so even if you could delete it I doubt it would be more than a drop in the puddle in terms of salvaged storage.
