aben Posted June 21, 2022 Share Posted June 21, 2022 (edited) @PC IT Hi - please try booting Ventura with below attached EFI. Test EFI as-is without making any changes; if display works then you may proceed with adding relevant kexts.

Guest ricoc90 Posted June 21, 2022 Share Posted June 21, 2022 (edited) Yeah, I'm a little late to the party. Haven't done anything hackintosh-related in the past 3-ish years, but a certain moderator on this forum who's name shall not be mentioned (starts with C and ends with yberdevs) kept tempting me to come back (j/k), so I decided to give it a go.

I'm afraid that I am unable to help any further as I simply cannot see the root cause for your LVDS to stay "off" only when booting macOS 13 even with settings provided earlier, quite strange tbh. Can help with one more EFI - have included more boot-args + device properties that could potentially fix the issue, test and see, if still no dice then I'm not sure how else this issue can be fixed, maybe try experimenting with other KBL profiles listed here . Also, clear NVRAM before you boot - have included the option in OC picker. Good luck! EFI.zip Link to comment Share on other sites More sharing options...

Donw35 Posted June 21, 2022 Share Posted June 21, 2022 Used the latest OC and latest versions of kexts, messed about with the config.plist from some others input from what I saw from their experiences. Good to go... 4 Link to comment Share on other sites More sharing options...

You don't have to install kexts on S/L/E anymore.. you need to keep the kext on OC/Kexts and load them in the config.plist Link to comment Share on other sites More sharing options...

Cyberdevs Posted June 21, 2022 Share Posted June 21, 2022 Display loosing signal after loading macOS: I made another discovery today which might be helpful to people with the same issue. On my KabyLake (Formerly my SkyLake rig which I swapped the 6700K with a 7700K CPU) I tried to boot into Ventura using the Intel HD630, the system booted off of the iGPU and then after the second stage boot shortly after loading the desktop the display went black and i had to turn it off and on and then the signal came back and i could see the desktop, After trying several SMBIOS settings (iMac18,1; MacPro7,1 and Macmini8,1 work fine by the way) I realized under the DeviceProperties I had this entry to disable my dGPU (R9 270X) so I decided to remove that entry and by doing so the issue got resolved. 6 Link to comment Share on other sites More sharing options...

I'd suggest omitting SSDT-PNLF as well while you're at it. From what I could gather, it looks like your HD+ TN panel has a constant PWM frequency of 200 Hz that does not seem to be compatible with PWM base frequency values from KBL framebuffer. You can test this theory out by spoofing your SKL iGPU to KBL on Monterey and see if display still works. If not, that means there's only two potential, albeit not-so-viable options I see that could solve this particular use-case for macOS 13: By patching "BXT_BLC_PWM_FREQ1" with help of WEG to better suit your panel when using KBL kext (not sure how this can be achieved easily with current WEG, maybe there is a configurable boot-arg or iGPU property that I'm not aware of but unless someone has access to this hardware and is willing to contribute code-wise, this option is highly unlikely) Upgrade your panel to FHD IPS or TFT (more viable option) Personally I would recommend waiting it out, testing through the beta cycle, till official release of macOS 13, given that SKL is not officially supported by Apple on Ventura, possibility of additional patches are imminent. Worse case - no choice but to stay on Monterey. 1 Link to comment Share on other sites More sharing options...
