BogusBogey Posted June 26, 2022 Share Posted June 26, 2022 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 Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted June 26, 2022 Moderators Share Posted June 26, 2022 all those ssdt are integrated into SSDT-840G3.aml or implemented in the config file or replace with kexts. the ssdt is significantly reduced due to removal of battery patches, now using ECEnabler.kext only.

BogusBogey Posted June 26, 2022 Author Share Posted June 26, 2022 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?

Moderators Jake Lo Posted June 26, 2022 Moderators Share Posted June 26, 2022 if that fixes your boot issue, then it's good. Link to comment Share on other sites More sharing options...
BogusBogey Posted June 27, 2022 Author Share Posted June 27, 2022 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 Link to comment Share on other sites More sharing options...
xworm Posted June 28, 2022 Share Posted June 28, 2022 Great to hear G3 series running 12.4, I've been trying some EFI supporting 12.3, but failed on 12.4. would you pls. kindly share your EFI folder ? thanks! Link to comment Share on other sites More sharing options...
xworm Posted June 28, 2022 Share Posted June 28, 2022 I just tried searching in forum for my laptop model, can't believe @Jake Lo has posted the OC EFI package. thanks a lot! I'm writing this in macOS 12.4. Link to comment Share on other sites More sharing options...
BogusBogey Posted June 28, 2022 Author Share Posted June 28, 2022 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? Link to comment Share on other sites More sharing options...
xworm Posted July 3, 2022 Share Posted July 3, 2022 thanks @BogusBogey I'm stay with the package Jake posted here : almost everything works as expected, except bluetooth: bluetooth audio works, file transfer too. but airdrop can't detect other devices, while reversed scenario works. I'm using Broadcom 94352Z from Lenovo, but it shows like this: not sure is that normal in Monterey? Link to comment Share on other sites More sharing options...
