Thanks for the advice! However, with this layout, the additional monitor did not start I solved the problem by changing the argument: AAPL,ig-platform-id 0500260A DATA (however: To be usually used with HD 5000, HD 5100 and HD 5200)....

It's still a problem. The main screen of the laptop shows an image when something moves on it. as soon as the picture becomes static, the image from the screen disappears (black screen). I recorded a video. ioreg file attached MacBook Pro24.11.22.zip

attached file MacBook Pro_with_monitor_1.zip

Thank you! There is already progress. when I booted from the config1 file (renamed it "without 1"), the laptop booted up with a black screen, an image with artifacts appeared for a second when I inserted / removed the usb flash drive, and connected the display port. When the display port was connected, the image on the additional monitor appeared, but the laptop monitor did not.

I apologize! File not attached MacBook Pro_without_monitor.zip

I am connecting a DP to DP cable. The monitor says: the DP cable is connected, and after a while it writes that "there is no signal via DP". The monitor goes to sleep.

Thank you! Well, now when connecting/disconnecting the cable, the port display does not freeze the operating system. But there is no image on the additional monitor (the monitor goes to sleep)

Thanks, but monitor not work. MacBook Pro.ioreg

So, when I connect the cable, the operating system freezes (only a hard reboot on the button helps)

Yes, I did reset nvram. But no result.. Any other ideas?

No, This change did not help. The monitor still does not work through the DP

Hi everyone. I managed to start Monterey on my old 650g1, (i5, 8GB, ssd.) The system works quickly, without logs. But how do you make the display port work? My loader and config file are in the attachment. config.zip

brcmbluetoothInjector.kext blocked the system. Removed it from the config - and everything worked! The installation of the system went to the internal ssd

what is the name of this pest?

Thanks for the advice. I tried the kext data - the result is bad (the installer does not see the disks). I have two 650g1 laptops. Two laptops do not see disks during installation. In the BIOS, the disks are visible, on these disks there are "combat" working systems. Windows / fedora. What am I doing wrong. ? My efi is in the attachment EFI.zip
