OS reboot when connected to HDMI cable

[Hendawy]

Now I removed all the SSDT files from the patched folder as you asked and unmarked the checkbox of drop OEM, and Installed the mentioned kexts but I don't know what will be changed after, also regarding enable the settings in the plist what will effect

you seem to have a patched AppleHDA.kext (it shouldn't be listed in your kextcache output)

would be best to re run the macOS installer (without wiping) to refresh your kexts

then in config.plist:

<key>Fixes</key>
            <dict>
                <key>Comment-IRQ Fix</key>
                <string>The following fixes may be needed for onboard audio/USB/etc</string>
                <key>FixHPET</key>
                <false/>
                <key>FixIPIC</key>
                <false/>
                <key>FixRTC</key>
                <false/>
                <key>FixTMR</key>
                <false/>
            </dict>

change to :

<key>Fixes</key>
            <dict>
                <key>Comment-IRQ Fix</key>
                <string>The following fixes may be needed for onboard audio/USB/etc</string>
                <key>FixHPET</key>
                <true/>
                <key>FixIPIC</key>
                <true/>
                <key>FixRTC</key>
                <true/>
                <key>FixTMR</key>
                <true/>
            </dict>

now the apple HDA isn't listed in the kext cache output and I changed the plist as you mentioned. but nothing changes when I tried to connect HDMI cable it rebooted again. I attached all the PR also I attached the problem error report the HDMI.

Must implement audio first.
Suggest AppleALC.kext.

I already installed APPLEALC.KEXT . PLEASE CHECK THE ATTACHED PREVIOUS DEBUG FILES

Try without FakePCIID_Intel_HDMI_Audio.kext.
Also, do a fresh install to insure you have undamaged AppleHDA.kext in /S/L/E.
