@iTTT, I am afraid we did not understand you. Could you be more descriptive on what happens, perhaps make a video or something…

 

Is it the following?

1. You hold CMD+V before starting OpenCore

2. You release it

3. You launch OpenCore Shell

4. A number of v keys appears in shell input, i.e. you see:

Shell> vvvvvvvvvvvv

 

If so, I cannot imagine why would you do that, and it feels kind of expected to me?

I too use apple wired keyboard. Without UsbKbDxe.efi, with Input section:

And with PollAppleHotKeys Yes

 

Check the last version OpenCore from master, there were many improvings for keys.

 

 

hello @vit9696 @Andrey1970

 

apple wired keyboard

 

 

A. use UsbKbDxe.efi, PollAppleHotKeys=NO, KeySupport=NO

1. ShowPicker=NO

2. i hold Option button before starting OpenCore

3. release it and lanuch OpeCore Shell

4. if i try to input some words like .. a , b .... then it will auto input and show like 

Shell > aaaaaaaaaaaaaaaa i/o just Shell > a

 

B. remove UsbKbDxe.efii, PollAppleHotKeys=YES, KeySupport=YES

1. ShowPicker=NO

2. i hold Option button before starting OpenCore

3. system just auto login OSX i/o show up OpenCore Picker.

 

now i use Pavo's OCBuilder to upgrade all my OpenCore files and drivers but still nothing change.

 

thanks.

Hi. How do i setup the CPU frequency and BUS speed in opencore. Because in opencore have ARTfrequency and FSB frequency. My clock is very slow.

Hi,guys, dose anyone know that how to record backlight on OC, it works on clover.

I find that the nvram contains backlight variable, but it seems can not be read when booting.

Hello guys

What is the way to boot Linux with OC?

In my old setup, I boot Linux through Clover using this:

After resetting NVRAM from OpenCore everything starts on russian language ?

Linux, macOS Installer, etc

 

How do i reset it as english ?

search in config

prev-lang:kbd

and put there right value

if you use string value it is

en:0

if you use data value you have to convert in that format

 

for your info here you can convert value on line:

@Download-Fritz, thank you.

My issue is to find correct way to call vmlinuz-linux...

Also for those interested.

Quadruple boot with OpenCore: ( Catalina, Mojave, Windows, Ubuntu ) Smooth experience 
My path entry for Ubuntu is:

PciRoot(0x0)/Pci(0x17,0x0)/Sata(0x2,0xFFFF,0x0)/HD(1,GPT,6764064E-FA1D-4FC7-AEF5-C94FAE30F973,0x28,0x64000)/\EFI\ubuntu\grubx64.efi

@Ellybz, thank you.

The thing is I am not using any bootloader like Grub. Am trying to use OC to boot Linux directly. You can find more information about to boot Linux through Clover in: https://wiki.archlinux.org/index.php/Clover

Not Sure I understood. Similarly to Clover, You can use OC to boot any OS you'd like. Have you tried the following boot entry ?
PciRoot(0x0)/Pci( 0xXX, 0x0 )/XXXX.(0x0xXXXX.0x0)/HD ((1,XXX,,XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX,0xXX,0xXXXXX) /\EFI\Archlinux\vmlinuz-itz

You can find the hidden path thru the Clover Bootlog. ( Shell method for linux is incomplete ).

[UefiBooter]

you can boot most vmlinuz files directly as they usually contain an efi-stub, without the need for grub, if you load ExtFs driver and then reference the file directly and pass appropriate arguments.

[jl4c]

@Ellybz, @UefiBooter

Thank you, is working now.

Guys, in config.plist I've renamed the method _Q13 to XQ13 and used this code to map brightness keys:

External (\HKNO, FieldUnitObj)
External (\_SB.PCI0.LPCB.PS2K, DeviceObj)

Method (_Q13, 0, Serialized)

{
    Local0 = HKNO
    If ((Local0 == 0x07))
    {
        Notify (\_SB.PCI0.LPCB.PS2K, 0x0405)
    }

    If ((Local0 == 0x08))
    {
        Notify (\_SB.PCI0.LPCB.PS2K, 0x0406)
    }

    If ((Local0 == 0x04))
    {
        Notify (\_SB.PCI0.LPCB.PS2K, 0x046E)
    }

}

I wonder how can I make this code only work for Darwin (aka If (_OSI ("Darwin"))) and return to original code (XQ13) for Windows and Linux.

Not sure, you have to test it.

DefinitionBlock ("", "SSDT", 2, "HACK", "_Q13", 0x00000000)
{
    External (_SB_.PCI0.LPCB.PS2K, DeviceObj)
    External (HKNO, FieldUnitObj)

    Method (_Q13, 0, Serialized)  // _Qxx: EC Query, xx=0x00-0xFF
    {
        If (_OSI ("Darwin"))
        {
            Local0 = HKNO /* External reference */
            If ((Local0 == 0x07))
            {
                Notify (\_SB.PCI0.LPCB.PS2K, 0x0405)

            }
        }
    }
}

@hardcorehenry, thank you

Yes, the code provided was the first one I tried, the problem is that it works for macOS (Darwin) but doesn't return to original code (XQ13) in DSDT for Windows or Linux. So the brightness keys do not work in those operating systems.

Edited November 11, 2019 by jl4c

[Regi Yassin]

@jl4c why not just use Else { Return (XQ13) }

if the original method is not in any scope/devices, if it is, example inside SB (\_SB.XQ13)

[jl4c]

@Regi Yassin, this I tried without success

 

 

This is the output from Linux:

[   26.811221] atkbd serio0: Unknown key pressed (translated set 2, code 0xab on isa0060/serio0).
[   26.811229] atkbd serio0: Use 'setkeycodes e02b <keycode>' to make it known.
[   26.817616] ACPI: BIOS _OSI(Darwin) query ignored

Copy to Else original code _Q13 from DSDT.

[jl4c]

@Andrey1970 thank you

Yes, that is logic. What am trying to do is precisely avoid to copy the entire code from XQ13 in DSDT to this little SSDT and call the method (XQ13) from it.

You won't be able to use XQ13 in DSDT, because this method was deactivated by renamings _Q13 to XQ13.

@jl4c

Your example shows that is really necessary the DarwinOnly=Yes for ACPI Patch. Try to persuade @vit9696.

 

Otherwise only this way:

I am not sure of this, as an example, you can take the method with which Rehabman fix instant wake on usb ports, where the SSDT returns to the original code (XPRW) in DSDT.

DefinitionBlock ("", "SSDT", 2, "HACK", "GPRW", 0x00000000)
{
    External (XPRW, MethodObj)    // 2 Arguments
    Method (GPRW, 2, NotSerialized)
    {
        If ((0x0D == Arg0))
        {
            Return (Package (0x02)
            {
                0x0D, 
                Zero
            })
        }
        Return (XPRW (Arg0, Arg1))
    }
}

Can you just add the a Method for _Q13 instead of renaming XQ13?
