joelhanducky Posted January 21, 2021 Share Posted January 21, 2021 Recently I have been working on this Hackintosh and realized that sometimes the top of the Safari tabs get a bit of screen tearing, but also that whenever using Logic Pro X, the white line which goes across the screen to represent time passing doesn't render properly, it will only update the render when you spam click the mouse. After doing some research I realized that it was a graphics issue and that on my About My Mac settings, under Graphics it only shows Display 8 MB and I have been trying to troubleshoot this so that it will recognize my iGPU (it wont recognize my dGPU as it is NVIDIA) Linked down below is a screenshot of the issue I'm having, and the EFI file I'm using. With VTX turned on in my BIOS I was able to get a boot up with SSDT-Disable-DGPU.aml, but was still having this same issue. When I tried enabling Switchable Graphics at all it would not boot. Anyone have any suggestions or pointers to help me solve my issue? Current EFI.zip Link to comment Share on other sites More sharing options...

joelhanducky Posted January 21, 2021 Author Share Posted January 21, 2021 All I see the Apple logo on boot and black bar with no progress. I tested with and without VTX on and got the same result. (switchable graphics always on) The common thing I notice happen is that whenever I enable switchable graphics, the hack doesn't boot. However if i disable it or enable VTX with what u suggest it will boot but the Graphics wont display my iGPU properly. Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted January 21, 2021 Moderators Share Posted January 21, 2021 That's because iGPU is enable only if Switchable graphics is enable in BIOS. If you disable it, then only the Nvidia is on but it's not supported. What's the specs of your 7520? Need to determine if you have Skylake or Kabylake processor Link to comment Share on other sites More sharing options...
joelhanducky Posted January 21, 2021 Author Share Posted January 21, 2021 Here is the specs sheet from the Dell website I believe my processor is Kaby Lake generation 1 Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted January 21, 2021 Moderators Share Posted January 21, 2021 are you sure, bottom of list also shows i7-6820hQ which is Skylake. You can easily confirm by checking it in the BIOS Link to comment Share on other sites More sharing options...
joelhanducky Posted January 22, 2021 Author Share Posted January 22, 2021 on my BIOs it shows i7-7920HQ CPU @3.10Ghz Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted January 22, 2021 Moderators Share Posted January 22, 2021 try to see if this boots with graphics acceleration. then we'll fix the rest config.plist.zip 1 Link to comment Share on other sites More sharing options...
joelhanducky Posted January 22, 2021 Author Share Posted January 22, 2021 It seems that graphical acceleration is on as my system doesnt feel laggy and everything is running smoothly. (Chess rotating works fine, crtl-up/down to switch around is smooth) Link to comment Share on other sites More sharing options...
joelhanducky Posted January 24, 2021 Author Share Posted January 24, 2021 Update: I was able to get it running with switchable graphics enabled by using an older EFI partition, not exactly sure why it works but it does, I can link my EFI and BIOs settings if anyone has the same issues I do.
