I can't get WOL working

[fttx]

Hi mieze,

on Windows it is working properly, but when i shutdown the computer from macOS it turns back on right after the shutdown, or instead, sometimes it shuts down also the network interface (no led) and WOL doesn't work

Bios settings:
Advanced/APM Configuration/ErP ready=disabled
Advanced/APM Configuration/Power On By PCI-E=enabled

Motherboard: ASUS z370-I
NIC: I219-V
Kext: IntelMausiEthernet v2.3.0

[Mieze]

That's not a bug, it's the specified behavior because macOS doesn't support WoL from S5.

[xenio]

After 1 week trying hundred of fix, patch etc, I just changed line 174 and 175 of IntelMausiEthernet.cpp to TRUE

wolCapable = true;
wolActive = true;

Recompiled the kext and WOL is now working as always was before I changed motherboard. Now I am on Asus Z370A Prime with Wake On Lan turned on in the Bios.

[fttx]

So does it work even with S5 when you cut the power off completely?

[xenio]

I am on Hackintosh and the pc is completly off (not sleep) only some motherboard leds are on.
You have to enable FixShutdown ACPI Patch in clover or the pc does not shutdown but always restart.
Se ti serve ti mando il kext compilato per provarlo.

Si, grazie filippo.tortomasi@gmail.com

I confirm that it works on hackintosh

Thanks a lot for the fix @xenio . Works great on the latest Mojave build.

@Mieze why don't you just turn on these parameters by default?
Thank you for your work btw.

The driver works as designed because macOS doesn't support WoL from S5 so that there is no clean way to enable or disable it by the OS.

[fttx]

Maybe a solution could be to enable it through a clover boot flag?

Hello xenio.

thanks so much, now my hackintosh can use WOL now.
but i find one issue. if i put my osx into sleep -> wake it up and then power off it.

WOL will not work.

any solution to fix it?

thanks

@wmjlxl I am sorry I have no idea, I am not a developer.

@Mieze I'm not sure if it's macOS directly and suspect it's more of the Clover DSDT/ACPI
config issue. OS does not seem to be involved in this process.

Is there any chance you'd be able to share that kext with me? I have no idea how to compile a kext, but that fix of yours is literally the last thing I need to make my new rig PERFECT. lol ... If you could share it with me, it would be greatly appreciated!

@TokyoHam
You can find such a kext here.

You can find such a kext here.

Wow, that's amazing. Thank you so much!! Making a complete backup of my macOS drive right now, and then I'll give this a try. I can just remove the original IntelMausiEthernet.kext, and put this one in, instead? I don't need to clear NVRAM or rebuild kext cache (?) or anything like that?

edit: yup, it was that simple. The kext works perfectly! I am now able to completely power off my Hackintosh from both Windows 10 and macOS, leaving my NIC powered on to receive WOL packets ... I just SSH in to a Raspberry Pi, and have it transmit the WOL request from inside my LAN, and the Hackintosh powers right up. I have Clover set to auto-boot macOS on a 5-second delay, which means I can then use my go-to VNC client to remotely access the computer. Perfect!! Thank you again for your help.

It seems like this does not work using OpenCore.
Has everyone managed to enable WOL using OpenCore?

[th0u]

@TokyoHam Thnx for the hint regarding WOL.
After adjusting wolCapable = true; and wolActive = true and compiling, I was able to WOL my PC after it was shut down.
I use reFind + OpenCore 0.5.7/Catalina + Win10Pro (all on different disks)
Thnx.

Is this still true?
Why is it working for @xenio ?

[Mieze]

Apple has never made any efforts to support WoL from S5 and will most likely never do. Therefore I have no plans to implement it as it might cause harm to those who don't need it.

On the other hand, IntelMausiEthernet is published under the GPL and everybody is free to customize it according to his or her needs. Technically it's not that hard to add this feature so that I think it's the best way to leave it to the users.

[1alessandro1]

To enable WoL, is it enough to add the changes from this commit to IntelMausiEthernet.cpp?

acidanthera/IntelMausi@46360d8

and also, in the acidanthera repo, in the changelog they said they fixed I219 WoL functionality, so it's enabled by default?
What do you think from these commits?
