Mac and iPad AirPlay to EShare projector displays black screen after macOS 27 / iPadOS 27 update

Screen Mirroring / AirPlay connects to projector (EShare / iMirror) but only displays a black screen after macOS 27 / iPadOS 27 update.


Hello Everyone. Prior to updating to macOS 27 and iPadOS 27, wireless Screen Mirroring worked without issues. Since the update, whenever I initiate Screen Mirroring to my projector from either my Mac or iPad:

  1. The device appears normally in Control Center / Displays settings (EShare-xxxx).
  2. The connection succeeds (the Mac recognizes it as a secondary/mirrored display, and the projector status shows as connected).
  3. However, no desktop or video feed is displayed on the projector. It remains completely black.


Troubleshooting Steps Already Taken:

  • Wired Connection: Tested mirroring using a USB-C to HDMI cable, and the picture displays immediately and works normally. The black screen only occurs over Wi-Fi / AirPlay.
  • Network Settings: Disabled iCloud Private Relay and disabled Private Wi-Fi Address on both devices; both are confirmed on the same local subnet (10.138.4.xxx).
  • macOS Display Settings: Adjusted external display resolution (tested 1080p, 720p at 60Hz) and toggled between "Mirror Built-in Display" and "Separate Display".
  • Dedicated EShare App: Attempted connecting via the official EShare client for Mac (Version 7.7.0722), but it fails to push video frames.

Has anyone encountered this AirPlay stream decoding failure on third-party receivers following the OS 27 update, or is there a specific AirPlay codec/extension setting on macOS 27 that needs to be configured?



Additional information:


Device & OS Details:

  • Mac Model: MacBook Air M2 13 inch
  • Mac OS Version: macOS 27.0 (Build: 26A428)
  • iPad: Updated to iPadOS 27
  • Receiver: Smart Projector running EShare / iMirror receiver (EShare-xxxx)

Hi there

Please try this


Open the EShare / iMirror application interface directly on your projector using its native remote control.

Navigate to its internal Settings menu.

Look for Hardware Acceleration (sometimes labeled as Video Decoding Mode, Codec, or Player Settings).

Change the setting from Hardware to Software, or explicitly toggle Screen Mirroring / Video Playback Acceleration to OFF

iPadの場合, "EShare for iPhone"をインストール.

アプリからiOSの画面収録機能を使って画面ミラーリングできる.

AirPlayの不具合は解決されないが,問題の回避方法として使える.

auto-translate from Japanese:


For iPad, install "EShare for iPhone." You can mirror your screen using iOS's screen recording feature from the app.


AirPlay issues are not fixed, but they can be used as a way to avoid problems.

Readers:


Apple does not know this is a problem from postings here. Apple does not follow these user-to-user discussion forums.


To get recognition of the problem, each of you should post as a Bug Report type report on the Apple Product Feedback pages. These reports ARE forwarded to the developers for appropriate action, but action is only taken when there are more than handful of such reports.

Same here iOS and MacOS 27 both give black screen to my projectors. Tahoe works fine. APPLE FIX THIS I've had to downgrade to Tahoe


I have the same problem using a Macbook Air M3 and an iPad Air M4, both updated yesterday to Macos and Ipados 27. All working good by the HDMI connection, black screen by Airplay. I've tried to connect my devices to several Airplay receivers (Promethean Active Panel 65", updated to the latest firmware), but I've always encountered the same difficulties. Some colleagues of mine tried to connect Macbooks and Ipads still running the 26 OS to the same screens and the connection works fine. Airplay is really essential to my teacher's activity, I'm very worried about this problem.

I can confirm we have this issue with our teachers sharing thier iPads to a MacMini both updated to 27.0.1. If we airplay to 26 it works fine. All the new privacy changes in OS 27 are breaking everything. Not a happy camper as we have over 165 Apple TV's and 85 Mac Mini's teachers cast to. Apple you need to fix this ASAP and release an update like yesterday!

Im facing similar issue:


"

MacBook Neo (Mac17,5), macOS 27.0.1 (26A434).


Kernel panic, 100% reproducible:

Open any camera app (Photo Booth, FaceTime, Cambly, Google Meet)

+ turn on Screen Mirroring to a Samsung TV

-> Mac freezes for a few seconds, then restarts.


6 panic reports, all identical:

[Exclaves] EXDisplayPipeService.swift:469: Fatal error:

expected: 3000, type: CAM


Camera alone works. AirPlay alone works.

Only the combination causes the panic.

"

I have been doing all that. The problem persist. Only when it involves airplay though. When using HDMI cable, everything works fine.


The projector fully updated.

I guess majority of the teachers having difficulty with airplay on OS 27. Hopefully Apple can fix this bug on next update

Today I've updated my Macbook Air M3 to 27.0.1 and as @pgeipel said, the bug hasn't been fixed. Still black screen on AirPlay. This bug must be fixed ASAP.

Have you had any update on this? we are having this issue too although ours is affecting iOS 26 too but only eShare enabled devices in the last month or so.

Not fixed yet on my end as of today. Lucky i could still use HDMI connection.

It's really bad. We have confirmed on our side that it is fine on 26.5 so it is between that release and 27 that the problem has presented itself. Come on Apple.

Thank you for your suggestion. I've forwarded my Bug Report using the link you attached.

I hope that other users who have posted here will also report the bug via the Product Feedback pages.
