From my experience, if your system previously required KDK for the root-patch of your need, OCLP will prompt you to download KDK for Sonoma 14.4 once it detects that the system update is in progress that is soon after you hit the update in System Settings iirc. But, the Modern Wireless patch...

Lets put it this way, AMFIPass is not directly related to OCLP patching for Wi-Fi. I only suggested it so you don't need to use -amfipassbeta boot-arg with the updated version of AMFIPass 1.4.0 IOSkywalk.kext is not something you install. You inject it via bootloader and that will be that. It...

I didn't find any issues with the brcm wifi related settings in your config.plist. My next question would be whether your system is patched with the newest release of OCLP or not. For Sonoma 14.4, you need to root patch your system with at least OCLP 1.4.0 or newer otherwise your brcm wifi will...

Posting your current EFI here may help as we can take a look.

Post your Can you post your original DSDT, EFI and IORegistryExplorer?

Here, try the attached EFI. I have not changed anything except for the kext.

While OCLP patch itself doesn't, replacing IOSkywalkFamily.kext may break I225 ethernet if it is attached to dext driver. For this case, you'll either need to use AppleIGC.kext or AppleIntelEthernet210.kext(with e1000=0) from macOS Monterey.

These are no no no. the correct command is fsck_msdos disk0s1

To completely power off, you'll need to enable ErP. I see that you have it disabled.

You need to change SecureBootModel to "Disabled" to boot Mojave and Catalina.

@Giskard As others have suspected, your config.plist has no SystemProductName defined; hence, the no supported OS message. You should be using iMac19,1.

You can try the commands below in recovery to boot. mount -uw /Volumes/NameofYourVolume bless --mount /Volumes/NameofYourVolume --bootefi --last-sealed-snapshot Once you are able to login, revert root patches, reboot, then apply OCLP version that works for your system. When kernal panic...

P E5300 lacks SSE4.1 support. The highest you can install is El Capitan.

The fact that you don't see the cloned drive as a boot device in boot picker is probably because it's missing the boot.efi in preboot volume /UUID/System/Library/CoreServices. I don't know which method you used to clone your current drive but if it's missing the linked UUID in preboot volume...

Hm... odd, I didn't spot any "New item" entry under any of the kexts in Kext Add section, So I've used your config.plist in my OC 0.9.6 EFI just to double check but I am not getting that "No Schema...." error log on boot. You would have gotten the error log in your first post If you had...

would you be able to post your config.plist?

Try disabling VT-d and iGPU in BIOS if not already.

Have you enabled DisableIoMapperMapping quirk? I think it's best use iGPU for Sidecar function if possible.

What about the system time in BIOS? Is it frozen? Does the time move? I'd try clearing the CMOS or maybe replace the battery if needed.

Try this patch included in OpenCore's sample.plist. Make sure Enabled -> Yes
