And airdrop, handoff, etc. works?

Can I have your EFI folder!

Sure, I will upload it later (as I’m writing this from my ipad right now).

I didn’t experience any slowness or something.

To switch to Sonoma I recommend SMBios Macbookair 8.1 for Skylake, Kabylake and Kabylake Refresh, the HW gen is practically identical for these series and therefore the use of this SMBios guarantees the best functioning...... MacbookPro 15.x would be a stretch as it has a Coffelake CPU

 

AAPL,ig-platform-id Data 0000C087 or 0500C087
device-id Data C0870000

 

 

Something surely to check out. 
Question: do you have wifi working and how did you do that?

I upgraded my 850 G3 to Sonoma.

Changed the model from MBP 14,2 to 15,1 and I was able to install Sonoma (I used ocAuxiliaryTools.app to update Jake's OC 85 EFI to OC 95).

Sound worked, Network too. I don't know about bluetooth. Wifi didn't and here is when it gets tricky  

I made an attempt with OC Legacy Patcher but it didn't find the DW1560 wifi card.

@Jake Lo, do you think you can build a Sonoma configuration for the 8x0 G3 series?

Dortiana doesn’t have much on hibernation. But I did some experiments and was able to initiate hibernation (with hibernationfixup.kext). However, the victory was short lived, as I ended up with Rtc error on wake up. And… you guessed it, as with hibernation, not many people bothered to investigate in depth what regions are troubling. 

@Jake Lo do the sleep settings need adjustment too or does hibernation work?

 I would like to enable it.

What I tried is adding hibernationfixup.kext and switching from mode 3 to 25 and I also tried setting womp to 1, but it just sleeps regular.

Everything is up and running, thanks

I also checked my bios settings and there are three I don’t understand as they’re contrary to the recommended state in on other guides:

Power Management Options
Extended Idle Power States checked
Deep Sleep checked
Power Control unchecked

What’s the effect of these, in particular the last one?

Nevermind. Found it https://h10032.www1.hp.com/ctg/Manual/c06114605
 

cheers, Eddie 

@Jake Lo thanks for the Ventura update. I appreciate it very much.

Because Ventura officially doesn’t support Skylake processors, do we need to generate a new serial number? (as Apple’s serial numbers are associated with the model).

cheers,

eddie

I’m happy to help. I can send the EFI later (not at my computer right now).

I used Jake’s version 0.7.9 and updated the kexts and OC to 0.8.1

What model do you have?

Actually I had to add one extra (I found out that after insert/ejecting an USB drive I got the Post error again), so it becomes:

rtcfx_exclude=54,58,59,DF

Yeah, I checked those out with MaciASKL, I see how much could be reduced. Thank you 

Do you know if tdisabling the RTCFix patch and with installing the RTCMemoryFixup.kext and adding rtcfx_exclude=58,59,DF as boot-args it's all good?

Thanks @Jake Lo for your guide for running opencore 0.7.9 on the 840 G3. I was able to install Monterey 12.4 with OC 0.8.1

My 850 G3 has the latest BIOS v1.55 (April 2022). 

I have only one error visible: Post report on reboot. Setting DisableRtcChecksum to Yes, didn't work.

So I disabled RTCFix patch and with installing the RTCMemoryFixup.kext and adding rtcfx_exclude=58,59,DF as boot-args I don't see the error anymore.

I noticed that you don't use the suggested SSDT by Dortania, don't we need those? (SSDT-EC-USBX-LAPTOP.aml SSDT-IGPU.aml SSDT-PLUG-DRTNIA.aml SSDT-PNLF.aml SSDT-USBX.aml SSDT-XOSI.aml)

Also your SSDT-840G3.aml is a lot smaller than the other files with the same name out there, was there so much bloat in the other files?
 

How do I know if my system is working ok? I don't SEE any errors...

Thanks for the assistance.

Eddie
