screen mirroring broken with 15.2 update

To fulfill your request to make a Bug Report

Do understand.

Apple Will have to Test this issue rather extensively using the exact same equipment in your Specific Setup

When it comes to Third Party Displays, be it a monitor or TV.

Not so much as that falls outside the perimeters of support, unless the issue is coming directly from the Apple Operating System or Apple Computer

Feedback - macOS - Apple

This wording seems to imply, some Third Party Software used to Mirror from macOS to the Samsung TV

I once used such a software to Mirror to a Samsung TV Series 5 form an older version like macO 10.15 Catalina

The unfortunate thing is, this developer has not updated their software in 4 years

Could this be where the problems is ?

Same issue here. MacOS15.2 screen mirroring into Sony Bravia TVs (2 models) now broken. Screen mirroring still works into those TVs with MacOS14.2. I have filed a report.

I have a 16" MBP with M3 Max chip. Until this latest update Airplay has worked perfectly for nearly 3 years with Intel and Apple processors using our Samsing Q7 display. Don’t know why it would all of a sudden quit working after upgrating to macOS 15.2. Two associates with MacBook Pro 14” M1 Pro chips CAN connect with the Samsung TV via Airplay. Another associate with a MacBook Pro and an M1 chip can no longer connect as of this week and is having the same issues that I am.

I submitted a ticket through Feedback Assistant.

I had the same issue today with my MacBook Air M1, it only found my MBP intel for mirroring over BT after the update and refused to recognise the Gigabyte screen I use most of the time.

I found a Reddit post claiming that removing (MyHarddrive)/Library/Preferences/com.apple.windowserver.displays.plist would help, but it didn't.

Without putting the .plist back I switched form my Satechi USB-C to DDMI/USB hub to Apple's original USB-C to HDMI adapter and then it worked. It continued working after I switched back to my Satechi again as well.

Edit: After updating my Intel MBP, I just used the original HDMI adapter (without removing the .plist and it recognised the screen right away.

FWIW, you may also want to contact Samsung support. I have no problem mirroring to my TCL TV running Sequoia 15.2 which uses ROKU, but Samsung uses TIZEN.

Same issue here, connecting to either AppleTV running TVOS 18.2 or to Sony Bravia TV, both working just fine up til macOS 15.1/iOS 18.1

But screen mirror from iOS 18.2 to AppleTV does work.. hmm..

How about on macOS 15.2 the current version ?

It's the current version 15.2 that does not work here..

Have not loaded 15.3b yet.

My situation exactly. Apple 4KTV running TVOS 18.2. MacBook Air running Sequoia 15.2. Broken after upgrade on Sunday (15th).

Nope and even if I had

I would not discuss Beta Software here

Confidential and all that stuff
