iPhone mirroring stopped working with new iPhone

Found a great fix in another thread:

How to Fix iPhone 13 Pro Mirroring Issues… - Apple Community

The answer is - credit to user "HopefullyHelpful01":

(1) Running following command on terminal

defaults delete com.apple.ScreenContinuity

(2) Deleting file

~/Library/Preferences/com.apple.ScreenContinuity.plist

(i.e. you can run "rm ~/Library/Preferences/com.apple.ScreenContinuity.plist" while you're in the terminal)

This worked for me when manually removing all the plist files had not. I think the magic "defaults" argument is key.

100% my situation. Worked fine on 18.0 betas on an iPhone 14 Pro, has never worked with my new 16 Pro. Have tried the same steps and experienced the same effect. Have you filed feedback?

This worked for me; I had to switch to the new iPhone (reference: https://beebom.com/iphone-mirroring-not-working-fixes/ (Method #7)

Change iPhone Mirroring settings

From the menu bar in the iPhone Mirroring app on your Mac, choose iPhone Mirroring > Settings, then choose from these settings:

• Ask Every Time: iPhone Mirroring always asks you to authenticate before mirroring. Authenticate using your Mac login password, using Touch ID on your Mac, or using your Apple Watch. 
• Authenticate Automatically: After entering your Mac login password to select this setting, you are no longer asked to authenticate before mirroring. While this setting is selected, the “Require password after screen saver begins or display is turned off” setting in Lock Screen settings remains set to Immediately.
• Reset iPhone Access: Reset the iPhone Mirroring setup for this iPhone, including to remove “Allow notifications from iPhone” from Notifications settings on your Mac. To use iPhone Mirroring and receive iPhone notifications again, set up iPhone mirroring from the beginning. 

Start now and open an Apple Support Ticket as they are PAID  Apple Employees to deal will these types of issues . 

 Product Feedback - and make it known to Apple regarding this ongoing issue

This was the only solution that worked for me. In fact, had to sign out of all devices pretty much simultaneously. All devices are up to date. Initially signed out of iPhone 15 pro only which then mirrored correctly on my Air but not on my MacBook Pro 14″ so had to sign out of that too along with signing out and back in again on iPhone. At that point, did simultaneously sign out, restart, sign in on all devices including Watch.

Is the Work Computer using the Same Apple ID Account as the iPhone ?

Thank you for the solution, running the first command was enough to restart Mirroring setup and make it to work

Thanks This worked for me
