SSDTs are more flexible and to the point. DSDT patching is now kinda deprecated and seldomly used.

I’m having difficulties finding the specs of this ThinkPad X210 model. By now, the old member that you are should know that providing one's platform specs is the 1st requirement to obtain support and assistance. So please do so before anything else. This being said, given that you all you mentioned was UHD 620, we can only guess that your X210 is either: 8th gen Kaby Lake R 8th gen Whiskey Lake 10th gen Comet Lake The iGPU properties that require to be injected differ according to your system’s CPU family. Given that you appear to fake the id of a Kaby Lake R iGPU (0x5916), I suspect your X210 is of that particular generation. For such Kaby Lake R platform, the following properties usually are required: KBL framebuffer layout 0x59160009 or 0x591B0000 fake iGPU id 0x5916 SMBIOS MBP15,2 I invite you to consult the WhateverGreen User Manual. You'll find that the KBL framebuffer layout id you specified in your config does not exist which would explain a few things, wouldn't you say? I also doubt you need the CpuTscSync kext.

New update as of June 2021. See our article here. The above is now deprecated. Much improved kext written by Firewolf (aka Austere.J) available here: https://github.com/0xFireWolf/RealtekCardReader/releases

You can start by identifying the make and model... And, if as expected, it's a certain Realtek card reader, we have posted articles and threads about it.

Hmm, I do... Anyway, you know what you have now.

Erm... According to the Dell support web site, this XPS 15 9500 laptop is fitted with an ELAN touchpad: https://www.dell.com/support/home/en-us/product-support/product/xps-15-9500-laptop/drivers

When I asked about the model of NVME SSD, I meant make and model, not its physical form (and all NVME SSDs are of course M.2). So identify it, open the laptop and look at the label on the SSD if necessary.

What's the model of NVME SSD? Some are not supported.

What are the other specs? Wifi? Disk?

8th beta released September 28th, 2021. Build 21A5534d. As per beta7, I had to temporarily use SMBIOS iMac17,1 to complete the upgrade and avoid the boot loop problem. Other than that, all Ok on my Latitude E7270 (Clover r5133) and Toshiba Satellite R50-B (OC 0.7.0).

It depends entirely on the configuration parameters you're using. Monterey does not natively/officially support HD4000 graphics and Ivy Bridge platforms were dropped. As such, you have to adjust your config with a supported SMBIOS and you'll subsequently have to apply patching to obtain support for HD4000 graphics. Can't say more without more info from you at this stage.

No DRM fix for Netflix with Safari on Hackintosh laptops with Intel graphics, no. https://github.com/acidanthera/WhateverGreen/blob/master/Manual/FAQ.Shiki.en.md https://dortania.github.io/OpenCore-Post-Install/universal/drm.html On my Haswell or Skylake Hackintosh laptops, trying to view Netflix contents in Safari immediately results in a "Error code S7706" message. On my Ivy Bridge/HD4000 Latitude E6230 I can watch Netflix contents in Safari 14.1.2 under Catalina 10.15.7 (build 19H1417) or Safari 15.0 under Catalina 10.15.7 (build 19H1419) for just over 1 x minute before the screen goes green irrecoverably. This is something Shiki used to be able to fix but it has not been the case for years. Apple TV works ok for watching movies. Certainly works on all my Ivy Bridge/Haswell/Skylake Hackintosh laptops. TV+ or TV Shows won't though.

Your screenshot shows that macOS is not even starting to load... You need to update your OC config so that it matches the v0.7.3 standards and requirements. That's the trouble with OpenCore, they change the way parameters and elements of the config must be defined and organised from one version to the other. Given that they release a new version every month, it can be a pain in the backside... There are threads at InsanelyMac that provide full recap of what's changed from version n to version n+1. I suggest you consult them all so that you suss out what you need to modify in your config. Do follow the monthly updates posted at Dortania too. https://www.insanelymac.com/forum/782-opencore-releases/ https://dortania.github.io

OS X/macOS is not based on Linux and what you report is not a general issue affecting all Dell laptops. Did you try optional boot-args such as igfxonln=1 ? In all likelihood, this black screen on wake problem may be solved with some ACPI battery patch. Impossible to say more without any debugging info...

Post a zipped copy of your bootloader's EFI folder.

7th beta released September 21st, 2021. Build 21A5522h. Warning: the update will not go through on most people's Hack and will end up in an infinite boot loop unless SMBIOS is changed to that of specific Mac models. I do not have a list of SMBIOS with which the update goes through but iMac17,1 certainly is one. SMBIOS that do not allow the update to go through include: MBP11,x / MBP13,x / MBP16,x. After rebooting Monterey beta6 with iMac17,1 SMBIOS, I was able to complete the update on my Latitude E7270 (Clover r5133) and my Toshiba Satellite Pro R50-B (OC 0.70). Switching back to MBP13,1 and MBP11,x after the update caused no adverse affect to Monterey beta7. This beta7 also appears to sign the death of nVidia cards. GeForce and NVDA kexts are gone, meaning end of native support for Kepler GPUs.

Instructions are available in the Dortania OpenCore guide: https://dortania.github.io/OpenCore-Install-Guide/

The OC EFI I posted for the Vostro 200 is for a Core2Duo Vostro 200, not for a Sandy Bridge Optiplex 790. It's totally different hardware with nothing in common and certainly not the patched DSDT so you simply cannot re-use the OC Pack I had posted.

Well, the guide does stipulate that you 1st have to ensure you have (emulated) NVRAM working; if you do not, that command will be useless. You also have to make sure that your OpenCore setup does boot macOS; Catalina to begin with (as precaution) then Big Sur.

Clover r5139 is just as good. I've in fact updated just a few days ago after running on r5133 for months.

Looks like your USB installer is not bootable. Was the key formatted HFS, APFS or FAT32. How did you install Clover, with what selected options/settings? Edit: with regards to formatting the EFI partition FAT32, the Clover instructions have always worked for me:

I run Big Sur with OpenCore on my old C2D Vostro200 which is limited to legacy BIOS mode. You may refer to my Big Sur guide for reference on the OpenCore setup for desktop in legacy mode. https://osxlatitude.com/forums/topic/11148-dell-vostro-200-st-with-c2d-e8600xeon-x5270-geforce-gt730gt1030-high-sierramojavecatalinabig-sur/?do=findComment&comment=106757 This being said, the Optiplex 790's documentation clearly indicates UEFI BIOS mode is available so you should use that for both Clover and OpenCore. See p56 of the Optiplex 790's owner manual. This, unless you cannot boot a USB installer key in UEFI mode, something I experienced on Sandy Bridge Latitude E6220 laptop.

If it's a connected TV, go to Netflix directly on to and you'll probably get 4K.
