Hi guys! Hope you're all doing fantastic! So, I was trying to get a better understanding of how we're supposed to add values like Audio Codec and Audio Out to config. I took a look at the Configuration PDF and I think I finally understood how to set it up. Still, interestingly enough, in my case at least, I have a boot chime with both Audio Out 0 and 2. I haven't tried the rest of them (from 0 to 4, since I've got 5 output ports, so N-1=5-1=4), but 0 and 2 seemed to work fine. I'm guessing that's probably normal...? Anyway, what I wanted to suggest is if you could maybe update the font of the pdf, because bold text on that font is almost the same as regular which is not good when the bold text is actually what you're looking for. Here's an example of what it looks like in Preview (the default app for PDFs) and Typora. If you can tell me which part is bolded in the first screenshot, without looking at the second one, I'll give you a beer. And not Corona. :)) And here's from Typora. Same text, just copy-pasted in another app. Literally night and day difference.

Update made OpenCore 0.5.9 N-D-K fork... all is well...

Well Said Buddy.

Remember .... we're not in normal world at moment. Let's a hope he is safe, well and healthy and not worrying about OC.

hi... done.. c.frio

Glad you got it working. Interesting. I have AdviseWindows=NO and I do not have any problems selecting Windows on Startup Disk. In my config, I have: PlatformInfo->PlatformNVRAM->FirmwareFeatures = FD8FF53E PlatformInfo->PlatformNVRAM->FirmwareFeaturesMask = FF9FFF3F Maybe FirmwareFeatures value is allowing me to successfully select Windows. That is, FW_FEATURE_SUPPORTS_UEFI_WINDOWS_BOOT bit set in my FirmwareFeatures value. UPDATE: From sources: #define FW_FEATURE_SUPPORTS_CSM_LEGACY_MODE 0x00000001U // bit 0 #define FW_FEATURE_SUPPORTS_UEFI_WINDOWS_BOOT 0x20000000U // bit 29 So in my case, FW_FEATURE_SUPPORTS_UEFI_WINDOWS_BOOT bit is set and FW_FEATURE_SUPPORTS_CSM_LEGACY_MODE bit is NOT set. Therefore, no dot need AdviseWindows=Yes. Check yours in terminal: nvram 4D1EDE05-38C7-4A6A-9CC6-4BCCA8B38C14:FirmwareFeatures

UPDATE: Sure enough the solution is on the Docs, set AdviseWindows=YES

I completely don't understand what you mean fella? Explain???? For Starters my Files are not made for your board, I do not support the Z390 Ultra and nor do my EFIs sorry. Clovers DSDTs are no good for your board and You're better off using OpenCore and start from the beginning using there guide. https://dortania.github.io/OpenCore-Desktop-Guide/config.plist/coffee-lake.html I would of thought the title of my Thread was Obvious.

Thanks, @vit9696

I might be wrong but I'm thinking OC sets these values accordingly depending on your partition schemes, whether EFI is first partition or not, when you have AdviseWindows=YES. I don't remember setting any of these values on my config manually. I might try clearing NVRAM to remove these values, set AdviseWindows=NO then check again if OC will set something. I'll probably not, I have it already working. But I may if no one validate or invalidate my theory.

You nowhere said it was unbootable, only that it was not accepted as default entry from macOS Startup Disk. macOS Startup Disk, as it uses said Apple boot policy, does not have the concept of multiple OSes per partition. It stores only the partition (not file) information into NVRAM and then lets the firmware (Apple EFI, here accounted for by OpenCore) decide which file is bootable on the partition - this happens by an algorithm detailed in the PDF. Without BlessOverride, bootmgfw can never be the determined boot file from this partition node, this is the whole reason we have BlessOverride in the first place, and that is exactly what you are seeing. Previously, we adhered to one OS per partition (enforcing Apple rules and our extensions) and when scanning did not yield any entry for this partition (e.g. BlessOverride does not contain the necessary file), custom entries were chosen by partition matching. Now, we support e.g. arbitrary Boot#### entries and such, hence partition matching is no longer utilised - this is what breaks this behaviour for you. However, that was never "supported/recommended" in the first place, that was just what happened to be the implementation. Multiple OSes on a partition refers to the amount of non-alternative (e.g. macOS Recovery can be alternative on FileVault setups) booters on one partition. OpenCore and Windows sharing an ESP does count as "multiple OSes".

I am new to OC (new since 0.5.5) so don't know if OC had a feature before 0.5.5 to bypass ACPI mods but you may be thinking of @n.d.k's fork of OC that has that feature. I think Clover does not pass on the ACPI mods/patches to Windows but only macOS. If you do make to _OSI edits to your SSDT's (not all SSDT's need them BTW), then it would be good to share them here

The windows install works 100% with Clover. I remember OC used to have a setting that wouldn’t pass its specifics to windows but that’s since been removed. I guess I’ll have to work out how to implement the _OSI checks to my SSDT’s so they don’t get passed through to windows.

You can install it via whatever you want. In fact, installing it via BCA has its own issues, as you can see in my previous post here. :)) But yes, with some "help" from certain SMBIOSes, you can install it on a different drive, as well, via BootCamp. But...it would probably be easier to just make a USB drive in Windows, or using UnetBootin on MacOS, boot into it, install it and be done with it. Still, since you are using multiple drives, you can expect some errors (at least I had plenty of those) during Windows installation. Not related to BootCamp or anything. Just Windows being Windows. And, although it might not be the case for you, you might need to unplug some of your drives in order to complete the installation successfully. You can see some of my previous (bad) experiences here. So...I don't think the problem is that it's not installed via BootCamp... I had Windows installed before, and it wasn't via BootCamp. So...I feel like it's probably something else. Have you tried booting with Clover (just for comparison)? Does that work? Cause if it does, since it's the same Windows installation, it might be something specific to OC then. But personally I haven't had any issues.

@ainsleyclark Here’s a real review of one that’s not a intel sample but a true retail one done by jay2cents that’s much more in line with the story’s I’ve been told about them when I was at CES and beyond.

No Windows does not have to be reinstalled via Bootcamp. The ACPI errors seems "normal" if you have your own custom DSDT and SSDT's with "extensive" mods that you use/need for macOS. When OC "passes control" to Windows boot loader, that ACPI "environment" is passed Windows and windows can't handle. I now do NOT use my DSDT. I use simple OC ACPI patch capabilities such as renaming EHC1 to EH0, etc. There's one SSDT-EC.aml that has the required OS check in there (_OSI) to allows for non macOS's. and that's it. Windows boots fine.

Hhhmmmmm I’m not sure if I will bother with the comet lake range. im not impressed with a stop gap cpu that sucks 350+ watts (don’t believe the {censored} that Linus is coming out with about them as he’s been paid to say what he said about it ) I actually have a Z490 Master sitting there for me waiting for my collection and if intel give us a 10900k at the office then I will claim it if I can but actually buying it as a upgrade path from a 9900k, now that’s just pointless for the same tech but with two more cores. id wait until the ryzen 4000 desktop range gets launched and then see if intel has a reply to it like they are rumoured to have and releasing around the same time in September. We shall see anyway.

I included your theme into Clover-5118 release.

My Hack updated ok after four reboots

grazie @Mieze

For the love of all things good and hackable, can some kind person please look through my EFI Folder and tell me what I am missing causing a previous Boot-Chime working in OC 0.5.8 not to work in OC 0.5.9 - Cold boot, hot boot, different permutations you name I done it. I went to bed at 3.00 am this morning mumbling to my self with the wife threatening to send me to the spare bedroom. I am not desperate to have it's just the thought that something so simple (well I thought it was) is doing my head in. I don't usually ask for help, I tend to quietly just to figure things out, nothing to with pride just scared of looking and sounding stupid but as the saying goes ...'A Faint Heart Never ....... etc, etc. Ok enough of the mindless rambling please save my sanity, my marriage (rambling again!!!) and my Hack, take a look at the folder please (personal data removed) Thanks. EFI.zip

The kext injector is only for dGPUs for right now. I will look into adding support for iGPU in the future.

Can you please zip and attach the file here. You can change the connector type but eDP is the same as LVDS so it should not be necessary. Here are the connector types: Zero = 0x0 Dummy = 0x1 ; Always used as dummy, seems to sometimes work as VGA LVDS = 0x2 ; Just like on AMD LVDS is used for eDP DigitalDVI = 0x4 ; This is not eDP despite a common misbelief SVID = 0x8 VGA = 0x10 DP = 0x400 HDMI = 0x800 AnalogDVI = 0x2000

subscribed to this. i have a similar issue. i made a new pc with z390 aorus ultra/i9-9990k/rx5700xt and i cannot boot from the installed mac on the old pc (it was a z87-hd3 and it worked without issues all the time)
