How is your StartupMute showing with nvram -p command? is it shows <00> or <01>?

I didn't have "StartupMute" properties in my NVRAM when i run "nvram -P"

I have a question about Debug. I used Debug version then back to Release version, disabled watchdog settings clean the NVRAM but every restart OpenCore create an empty .txt file in EFI root. is it possible to tell OpenCore to stop creating a .txt file?

Chime working great but I notice a 2-3 sec delay before the boot picker and chime appears, maybe because of the Resources folder?

does anyone else experience the delay? i'm using the release version booting from my nvme's efi.

Getting Panic after AppleIntelCPUPowerManagement: initialization complete.

Was working fine with 0.5.5 RELEASE.

Trying with the latest commit.

I am on Ivy Bridge 3470 (CFG Unlocked) and using ssdtprgen PM.

I have been trying to get the correct layout id for my audio codec(ALC1220)

https://github.com/acidanthera/AppleALC/wiki/Supported-codecs

I have tried editing DeviceProperties>Add>PciRoot(0x0)/Pci(0x1f,0x3)>layout-id

I made sure to put the number in as a hexadecimal

according to some people I "layout-id" needs to be "Layout-id"

I still can't manage to get it working

I now have renamed HDAS to HDEF and still need to try out the layout id's with the rename

apparently you can use the alcid=xxx boot arg but I don't know where to place it

does it go under DeviceProperties>Add>PciRoot(0x0)/Pci(0x1f,0x3) or NVRAM>7C436110-AB2A-4BBB-A880-FE41995C9F82>boot-args

I also need to keep the npci=0x2000 boot arg under NVRAM>7C436110-AB2A-4BBB-A880-FE41995C9F82>boot-args or my Hackintosh won't boot

if you could tell me where to add the alcid=xxx boot arg or tell me if me any other error it would help alot

my config.plist is linked below

config.plist

It goes under NVRAM > 7C436110-AB2A-4BBB-A880-FE41995C9F82 > boot-args, like this really basic example for NVRAM;

    <key>NVRAM</key>
    <dict>
        <key>Add</key>
        <dict>
            <key>4D1EDE05-38C7-4A6A-9CC6-4BCCA8B38C14</key>
            <dict>
                <key>UIScale</key>
                <data>AQ==</data>
            </dict>
            <key>7C436110-AB2A-4BBB-A880-FE41995C9F82</key>
            <dict>
                <key>boot-args</key>
                <string>alcid=1</string>
                <key>csr-active-config</key>
                <data>ZwAAAA==</data>
            </dict>
        </dict>

You get the idea, right? That should hopefully get it going for you.

Hector van der Aa · March 1, 2020

but then how do I add multiple boot args

cuz I need to keep npci=0x2000 or my Hackintosh won't boot

Awesome Donkey · March 1, 2020

Well, like this...

                <key>boot-args</key>
                <string>npci=0x2000 alcid=1</string>

There ya go.

Hector van der Aa · March 1, 2020

thx ill try the layout id's and tell you if it works

that'll probably be tomorrow

hardcorehenry · March 1, 2020

Just tried out HfsPlus.efi from OcBinaryData, picker doesn't show black screen. I'll stick to my old one.

what was the procedure on opencore for dual boot windows on a single drive? with all the changes since .5.3 i havent followed along if possible can i get links to where it states the adjustments to make please?

aylamrin · March 2, 2020

I have a good working system with Clover 5103/10.15.2

Now I wish to move to OC. I tried 0.5.5 and was able to boot and everything working fine.

But now I wanted to check out the 0.5.6 and I built it. Since then I am not able to boot as I am getting KP.

^This also did not work.^

Could some kind soul help me?

I can provide my config and the log and the EFI dir if required.

P.S. I would really love to have a discord invite.

If your running windows

download propertree

add the kext to your kext folder in the oc folder

open propertree.bat and open your config.plist under file>open

then under click file>ocsnapshot and locate the root of the oc folder on the bootloader under EFI. Make sure to select the oc folder and not click into it

and clicks select

save your config and ur good 2 go

this can be used for any kext or DSDT or SSDT changes

Quick Update, removing my custom DSDT fixed the Audio issue, I had it since CLOVER days. (Still can't install BootCamp same issue)

Is a DSDT really necessary with OpenCore?

I also have the audio issue, what is the DSDT removed. Thank you.

Hector van der Aa · March 2, 2020

Try boot arg alcid=xxx

<key>boot-args</key>
                <string>npci=0x2000 alcid=1</string>

then try changing the alcid number for your correct codec

save and reboot between changes

My OpenCore (0.5.6) Catalina build (10.15.3) is running fine except for occasional freeze & kernel panics (maybe once or twice a day). Mobo is Gigabyte H87M-D3H, CPU is Core i5-4460, HD4600(headless) + RX 560 4GB. My config.plist is attached.

Here is the report when the system freezes.
I am not able to track the issue but it is somehow linked to GoogleChrome.
Any help would be appreciated.

Hi all, I can't play the bootchime at startup, I read the documentation, however I can't understand if the card is not supported by AudioDxe or whatever it is.

I'm sorry if this question was already answered, at p. 133 of this thread there's a similar opencore log, but I didn't understand the reply, if it was solved amd how.

The error is:

07:488 00:009 OCAU: Cannot find specified audio device - Not Found
07:497 00:008 OC: Audio connection failed - Not Found

Here are some info:

AudioCodec should be right according to the documentation and to IoRegistry Explorer.

I also tried 1 and 2 for AudioOut without success, don't know if I keep trying changing the AudioOut or not.

OCEFIAudio_VoiceOver_Boot.wav (16 bit, 44100 kHz) is in EFI/OC/Resources/Audio folder.

I have a nvidia gpu with hdmi output (HDAU) and a pci audio card (HDEF), and I'm trying to have the audio at startup at the pci card since hdmi is not supported.

The pci audio pci card (Realtek ALC899) accordingly to gfxutil is at PciRoot(0x1)/Pci(0x2,0x0)

Note also that this audio card work very good with AppleALC.

Thanks to whoever will point me in the right direction.

EDIT: I'm running latest Catalina with latest (as of today) version of opencore development (github); Catalina runs in a virtualized environment (qemu) with gpu and audio cards passed through.

I am in the process of updating from 0.5.5 to 0.5.6. I only use the release version from github. OpenCore-0.5.6-RELEASE does not contain BOOTX64.EFI. Is this not required anymore?

Hmm thanks. I re-downloaded it and now BOOT and Docs are there.

EDIT: I see what happened now. I think there's a bug in "Archive Utility". I download release zips for everything (opencore, WEG, lilu, etc). I select all of the zips, right click, chose open with "Archive Utility". All of the zips extract at once but Docs and BOOT are not extracted from the opencore zip. If I use "The Unarchiver" instead, everything is fine.

I normally using Resolution 'Max'. I want to try a different resolution and set it to 2560x1440@32. But it still shows as a Max on Boot. Am I doing something wrong?

Edit: Sorry guys I thought resolution also affects the Boot screen. But it didn't.

Hi all, I can't play the bootchime at startup, I read the documentation, however I can't understand if the card is not supported by AudioDxe or whatever it is.

I'm sorry if this question was already answered, at p. 133 of this thread there's a similar opencore log, but I didn't understand the reply, if it was solved amd how.

The error is:

07:488 00:009 OCAU: Cannot find specified audio device - Not Found
07:497 00:008 OC: Audio connection failed - Not Found

Here are some info:

AudioCodec should be right according to the documentation and to IoRegistry Explorer.

I also tried 1 and 2 for AudioOut without success, don't know if I keep trying changing the AudioOut or not.

OCEFIAudio_VoiceOver_Boot.wav (16 bit, 44100 kHz) is in EFI/OC/Resources/Audio folder.

I have a nvidia gpu with hdmi output (HDAU) and a pci audio card (HDEF), and I'm trying to have the audio at startup at the pci card since hdmi is not supported.

The pci audio pci card (Realtek ALC899) accordingly to gfxutil is at PciRoot(0x1)/Pci(0x2,0x0)

Note also that this audio card work very good with AppleALC.

What??? I have never seen audio device (HDEF) path with "PciRoot(0x0)/Pci(0x2,0x0)" for Intel chipset. Intel Chipset before SkyLake is "PciRoot(0x0)/Pci(0x1B,0x0)" and for skylake and above are "PciRoot(0x0)/Pci(0x1F,0x3)"
