This parameter is used to enable the internal Intel HD 4000 video card. And I don't know who is initial inventor because in those matter it can't work properly. The discussion was at tmx site as well wrong and without result. I was informed by Derek about this patch but initially it was wrong (byte 64 while it must be 63+65). It seems value 0xA0 will be better if used.Īnd I don't know interface for intenal screen.Ĭredits. My default values for desktop 0x80 (Digital, all undefined), for laptop 0x90 -6bits per color?! - not good. VideoInputSignal - this is additional patch for the same problem but I found no inluence.ĭigital input. With new Clover setting HorizontalSyncPulseWidth=100 there is a full solution. The apple is broken for a several seconds and then restored. Comment Patch 8 apples Disabled Find AQAAdRc= MatchOS 10.11 Name IOGraphicsFamily Replace AQAA6xc= īut this patch alone is not full solution. HorizontalSyncPulseWidth - this patch helps to resolve garbled screen at boot with Intel graphics. Remove this patch and brightness control is working again! Making this patch I found that Brightness control stop working. ProductID and VendorID- may be you want to mimic your display to be Apple manufactured. You have to set it to true is you do patches. Inject=true informs Clover to inject Custom or Discovered EDID into video device properties. You mostly don't need do it as Clover usually can obtain it by himself. ![]() Now ist may contain follow EDID section:ĮDID #Custom AP///////wAGECGSAAAAAAASAQOAIRV4CunVmVlTjigmUFQAAAABAQEBAQEBAQEBAQEBAQEB3iGgcFCEHzAgIFYAS88QAAAY3iGgcFCEHzAgIFYAS88QAAAAAAAA/gBXNjU3RwAxNTRXUDEKAAAA/gAjMz1IZYSq/wIBCiAgAJo= #Inject #ProductID 0x9221 #VendorID 0x1006 #HorizontalSyncPulseWidth 100 #VideoInputSignal 0xA5 Ĭustom is EDID obtained or created manually. You can override VendorID and ProductID in EDID. The main requirement is to have a correct maximal resolution.Īnother possibility is to use ViewSonic EDID Editor v3.1.5 that can easily be ported to Mac, if needed.Īn EDID from a Dell Inspiron will be used in the sample configuration file with a matrix of 1440x900.Ī custom EDID will also be used for automatic video bios patching. For monitors without DDC and for UEFI-only computers a custom EDID is needed.Ĭustom parameter is for providing custom EDID when it's missing. Clover will automatically extract the EDID and provide it to the drivers. In this case it is enough to set this option to. Inject parameter is useful when an EDID exists but is not seen by Apple's drivers. Old keys InjectEDID and CustomEDID were moved here. After quite some experimenting I can say that enabling TRIM for SSD () in KernelandKextPatches > KextsToPatch is not always enough for non-NVMe SSDs.EDID Inject Custom AP///////wAyDADfAAAAAAASAQOAIRV4CunVmVlTjigmUFQAAAABAQEBAQEBAQEBAQEBAQEB3iGgcFCEHzAgIFYAS88QAAAY3iGgcFCEHzAgIFYAS88QAAAAAAAA/gBXNjU3RwAxNTRXUDEKAAAA/gAjMz1IZYSq/wIBCiAgAJo= VendorID 0x1006 ProductID 0x9221 What has really proven troubling over time is that there is at least one important value that gets lost, which is the TRIM state to keep our non-Apple SSDs healthy and alive. It also comes in very handy that you gave us a way to keep significant NVRAM entries even after reset like the SIP state via csr-active-config. like that your flavor of NVRAM reset does NOT touch the UEFI BIOS boot menu entries but leaves them intact! when installing a completely new version of macOS. Sometimes that is of tremendous help to solve oddities, esp. boot-args (in Boot section) and csr-active-config (in RtVariables section), just to name the two main ones I can think of right you do offer reset NVRAM via the F11 key. ![]() Do you think you can just copy a (properly structured) ist into the EFI partition with Clover, or into EFI/EFI/Clover, and Clover would process it on startup and inject its content as values into NVRAM? Nowhere in any Clover documentation including on /5T33Z0/Clover-Crate I ever ready anything like that.Īs per OC2Clover#nvram-add, NVRAM entries that can manually be entered into Clover ist for injection on boot are e.g. Somewhat of an old topic, but still: I have no idea what you mean. If you switch emulate NVRAM into native, dont forget to copy your last ist one another folder of EFI.
