Your adapter has to be 4K capable; not all are. I have an Ivanky mini-DP to HDMI adapter and it's limited to 1920x1080@60Hz; I have the 4K-capable version on order.

Kepler GK208-based GT710/720/730 are only capable of 4K @24Hz (or is it 30Hz?) given that they have HDMI1.4 connectors so what you obtained was perfectly normal. I got exactly the same out of my GT730. The great thing is that this is obtained completely OOB. Getting 4K @60Hz out of your Skylake HD530 could turn into quite a bit of a challenge. If you check the specs go your i5-6500 CPU, you'll see that you get only 4K @24Hz out of HDMI but DP is supposed to support 4K @60Hz. You'll probably have to add some WEG parameters and it's also highly likely that you'll have to adjust/increase DVMT to support 4K.

Use the forum Search facility; if you don't find anything, there would be no tutorial, no. Seek inspiration in existing guides for Ivy Bridge laptops. You stated you have a Full HD display so I'll assume it is HiRes 1920x1080. This requires to use single-port Capri FB layout 0x01660004, not 4-port LoRes layout 0x01660003. Patching of the HiRes layout will therefore be required should you wish to gain DP and/or HDMI output. You may look this up in our dedicated HD4000 patching guide.

I would invite you to consult our threads about minimum requirements for running OS X/macOS and supported/unsupported graphics. https://osxlatitude.com/forums/topic/2998-min-requirements-for-os-xmacos https://osxlatitude.com/forums/topic/8238-supportedunsupported-gpus-graphics-cards I would invite you to consult Dortania's most excellent documentation, starting with the pre-requisites: https://dortania.github.io/OpenCore-Install-Guide/prerequisites.html#prerequisites

Is that a question? If so, it depends on the hardware specs.

Details of your card like make and model would also be most useful.

Mistakes are the best way to learn...

Unsupported graphics. Key pre-requisite: know you hardware. https://dortania.github.io/OpenCore-Install-Guide/prerequisites.html#prerequisites https://ark.intel.com/content/www/us/en/ark/products/65702/intel-core-i5-3570-processor-6m-cache-up-to-3-80-ghz.html https://osxlatitude.com/forums/topic/8238-supportedunsupported-gpus-graphics-cards You'll have to replace your CPU or add a supported graphics card. https://dortania.github.io/GPU-Buyers-Guide/

You sure run Catalina but without graphics acceleration, presumably because this is a plain vanilla install, so it's kind of useless. So, no, you will quickly find that everything does not work fine...

You don't seem to run High Sierra with graphics acceleration so I'm tempted to say that you don't even have a sound base for anything else. I would suggest you start by installing Mojave as per my Mojave guide by following to the letter, then upgrade from Mojave to Catalina as per my Catalina guide. Good luck.

Try the OpenCore guidance for Skylake laptops posted at Dortania site: https://dortania.github.io/OpenCore-Install-Guide/prerequisites.html

It sure was 19H2 last week after I installed it but whatever you say and it doesn't matter anyway.

'beats me. No issues with Catalina 10.15.7 (build 19H2) downloaded from AppStore and patched with Dosdude1's patcher for 10.15.7.

About this Mac does not reflect MBP11,1 and the serial # has nothing to do with the settings in the config I posted. There is still something fishy in your setup. Are you sure you replaced your OC files and folders with those I posted? Did you reset NVRAM in the OC picker? It's necessary here.

Try this revised E6430 OC setup instead of your current one: Revised_E6430_OC_pack.zip

Jake, being the experienced Hackintosher/guru that he is, could not have posted such a config for an E6430. You re-used stuff posted by @truceFR for which there is much to say in terms of adjustment and tuning -as detailed above- but it does not matter. Don't hesitate to read the OpenCore documentation available on the Dortania web repository for guidance. You may use tools such as Xcode, ProperTree or OpenCore Configurator to modify and adjust your OC config.

MBP14,1 is a Kaby Lake model; can be used for Kaby lake/HD620-based 7280 models. Skylake/HD520-based 7280 models should use MBP13,1.

Sorry but you claim to have followed my guide when you clearly did not. Apart from the required change of CPU PM generated SSDT, why don't you just use the packs I posted? given that the E6220 can run macOS without a patched DSDT, the config of my packs does not load any and uses patched SSDTs instead, it's far more efficient; your DSDT is therefore totally ignored. if you manually call for your patched DSDT, it'll clash with my config and some of the SSDTs of the Mojave/Catalina packs I posted; granted you opted not to use those tables unfortunately. you appear to have opted for a bastardised setup derived from my packs; you should refrain from doing that kind of stuff. you took the Clover config I posted but not the SSDT tables nor the posted kexts set. As such, you're ruining and invalidating the ACPI settings of the config (renamings, patches, SSDTs injections) and missing essential kexts such as Lilu, WEG or AppleALC. you've ended up with a messed-up and unsuitable Clover arrangement that just won't work, forget it. If you want to use my guides, please follow them to the full and do not butcher things. This being said, if you were following my guide and installing Catalina from an existing Mojave installation, why install 10.15.4 and not the 10.15.7 version currently offered by Apple for download? Unless you're fully experienced at it, you'd find it awkward to update from Dosdude1's patched 10.15.4 to vanilla 10.15.7 that'd need re-patcinhg thereafter. But it's up to you, have fun! NB: the bless-related error message at the end of the Catalina installation can be ignored. It's something that many people get with Catalina from 10.15.4 and I get that too. Catalina still boots afterwards and runs perfectly (with a correct setup of course).

Your OpenCore setup is incorrect in several aspects and this fully explains the issues you experience. 1st of all, do clean up your setup and get rid of unused patched tabes and kexts; this could only lead to potential confusion and trouble. Config: you appear to use 2 x patched tables for EC; that's wrong. Do not use SSDT-EC-USBX, Dortania's documentation clearly states it's for Skylake platforms and later; just use the basic SSDT-EC table. you inject an unnecessary property for your iGPU; HD4000 graphics does not require to patch stolenmem so get rid of that; the rest is Ok. your boot args in NVRAM section are contradictory with other settings of your config: you call on boot arg -igfxnohdmi to disable HDMI, yet you inject the iGPU patch that injects HDMI type to con1 (required for HDMI audio); get rid of this. you call on boot arg -no_compat_check, yet you use MacBookPro11,1 SMBIOS which is fully compatible with Big Sur; get rid of this, it''l prevent all Big Sur updates from being offered. you enable Xcpm kernel quirk alongside CpuPm quirk. Don't. Xcpm does not work or not reliably on these Ivy Bridge laptops. Since your using a generated CPU power management SSDT and CpuPm patch, stick to that only. given the above point, you also need to drop CpuPm + Cpu0Ist BIOS/ACPI tables for proper CPU power management. These drops are not enabled at the moment. Do so. CustomBiosGuid kernel quirk should not be required on an E6x30. Get rid of it. Kexts: There again you should get rid of your unused kexts (especially for USB ports) in order to avoid confusion and potential problems. There are probably a few more minor things but start by correct your setup according to the above list and things should begin to work properly.

Is this installation a distro? I suspect one when I look at the picture posted at bottom of p1.

Post a zipped copy of your Clover or OpenCore EFI with just the ACPI + Kexts folders + the config file. Obviously, you've got something wrong in your setup.

ExpressCards? Would you mind elaborate on this please?

Look up my recent Mojave and Catalina updates in my E6220 guide. They offer an installation free of patched DSDT, in UEFI mode and the posted pack contains all the SSDT tables + ACPI renamings in the Clover config to cater for brightness keys. You'll find the necessary code for Fn-UP/Fn-DOWN operation in the SSDT-Q66 table.

So you can apply the suggestions listed above; they appear accurate.

Not a platform supported by Big Sur. https://osxlatitude.com/forums/topic/8238-supportedunsupported-gpus-graphics-cards High Sierra is the end of the official road; Mojave and Catalina with specific patches to run graphics in non-Metal/OpenGL-only mode. See dosdude1's patchers on the web.
