How to Fix Airplay receiver? Computer says no During macOS Boot or Installation

Boot failures need a predictable pass through firmware, USB, storage, EFI and verbose logs before reinstalling macOS. Most installer stalls come from firmware settings, an invalid config.plist, wrong SSDTs, bad USB mapping or unsupported storage/controller settings.

Quick Checks

• Backup current state: Save a copy of your working EFI and run a full system backup before changing settings.
• Identify hardware components: Note down your exact CPU, GPU, Wi-Fi card, and motherboard/laptop model.
• Ensure utility alignment: Keep OpenCore, OCLP, and ProperTree updated.

Fix Steps

1. Create a rollback point: Make a Time Machine backup and keep a copy of your last working EFI folder before editing OpenCore, kexts or root patches.
2. Boot verbose: Add -v keepsyms=1 debug=0x100 so the final visible line gives a real clue.
3. Check firmware settings: Disable Secure Boot and Fast Boot, set SATA to AHCI, disable CFG Lock if possible, and use UEFI mode.
4. Validate OpenCore: Update OpenCore, Lilu and core kexts, then run ocvalidate or ProperTree clean snapshot.
5. Recreate the installer: Use a fresh USB installer and try another USB port; older Macs may need a USB 2.0 hub for input during setup.
6. Reset NVRAM: Reset NVRAM from the OpenCore picker before retrying the installer.

Verify It Worked

• Verbose boot moves past the previous stopping line.
• The installer reaches Disk Utility and sees the target disk.
• Keyboard, mouse and USB remain active during recovery.
• OpenCore picker still loads after a cold boot.

Rollback

• Restore the last booting EFI folder.
• Use the officially supported macOS installer to recover the machine.
• Do not erase the internal disk until the installer can boot twice consistently.

Original Question: "Airplay receiver? Computer says no"

I've been struggling with this now for a couple of days and don't know where I'm going wrong. I'm on a iMac 27 in from late 2015 (17,1) and I've been able to upgrade to Sequoia with OCLP (2.12), hoping that this will solve the airplay receiver issue. I've enabled feature lock, rebuilt and installed OCLP and rebooted, but still nothing coming up. I've also disabled "Allow native models" since it should be a supported Mac. It was enabled before and didn't make any difference. I'm losing my mind here, anyone that can help with a step by step of what to do? I'm new to this so might be going wrong somewhere. Thanks! https://preview.redd.it/6l9dnbxwga3e1.png?width=1464&format=png&auto=webp&s=51e734e6038a92fb161835ceea02f09caca5554f submitted by /u/Cautious-Point-3657 [link] [comments]
