Information about using your job

Hello guy,

First, sorry for my poor english and many thanks for all your great job. I try to install Catalina on my GPD Win Max but I can't use your EFI folder. I have an error message when OpenCore start : "Can't find configuration...".

I precise I haven't modified EFI values with your dump (I don't know how to do this but I'll try).

I found a tutorial on youtube with another EFI folder and, with this, I have been able to install Catalina on my SSD (https://www.youtube.com/watch?v=MeQ47uuKQ5k). But with this folder, no wifi, no trackpad, no touchpad...

So, my question is :

• Is EFI modification (with your dump txt file) mandatory for using your EFI folder ?
• When I have installed Catalina on my SSD, the only thing I have to do is to mount EFI partition and copy/paste your EFI content folder in EFI partition ?
• Could it be possible to have a little toturial, if it's more complicated ?

Many thanks for your time. Have a nice day. Bye.

(PS : I'm sorry if its not the good place to write this).

You can find most of the solutions here: https://dortania.github.io/OpenCore-Install-Guide/troubleshooting/troubleshooting.html#table-of-contents Also, google this error, you will find more information, I'm an amateur too, so I'm not very good at solving all kind of Hackintosh problems. First, it's not necessary to modify the EFI Second, if you have already successfully installed mac os, just copy my EFI to the EFI partition, then everything will work. Third, there are too many situations that need to be considered if I want to make a tutorial, my aim is at fixing more problems but not at how to make a tutorial, so sorry, I have no time to do too much about it.

Hello,

Many thanks for your answer. I'll try to read the Open Core documentation. Thanks for the link. I understand for the tutorial. It's making lot of time and it's not universal.

I'll try to resolve my problems and, if I revolve this, I'll send you a comment (for people who have the same problem like me).

If its possible, I have a little question for you :

• Trackpad and touchpad works for you. Is it only with the injected kexts or is the ACPI folder (DSDT, SSDT) are mandatory too ?

Many, many thanks for all. Have a nice day.

[kingo132]

Yes, you need both ACPI patch (dsdt,ssdt) and injected kext driver to use trackpad and touchpad, they are mandatory.

Many many thanks for your answer.

I tried to erase ACPI, Kext folders and config.plist with yours. I reboot. And... It's working very well. I have trackpad, touchpad, FN keys, wifi, bluetooth... All is working fine. I just changed the 4 Bios parameters (cfg-lock, Vt-d, Dvmt, XHCI Hand-off...). No modification with ru.efi or other.

Your the best. Many thanks for all.

Next step : try to install Big Sur (just for fun). Have a nice day. Bye

[kingo132]

You are welcome, and note you should replace the AirportItlwm.kext with the big sur version after you installed big sur. For now, it's the Catalina version.

If you used 1.1 bios, could you tell me where you found those bios parameters?

[yocoandplay]

Hello,

The parameters in bios are :

• cfg-lock: Settings > Power & Perfomances > CPU - Power Management Control > CPU Lock Configuration > CFG Lock
• Vt-d : Chipset > Super Agent (SA) Configuration > VT-d
• Dvmt : Chipset > Super Agent (SA) Configuration > Graphics Configuration > DVMTPre-Allocated
• EHCI Hand-off : Settings > USB Configuration > XHCI Hand-off

I tried with and without Vt-d and its working with the 2 options...

Have a nice day.

Next step : try to install Big Sur (just for fun).

Installed Big Sur directly with OpenCore 0.6.6.. Thanks for the BIOS settings locations. I left VT-d as enabled because as far as I know it's possible to disable this via config.plist ( it's probably the case ).

While OpenCoreConfigurator gave some warnings ( PS2 drivers not needed, some obsolete settings etc ), it's installed successfully.. I'll check the logs though, because I saw some problems scrolling on the screen during boot.

Display problems are really weird.. After moving mouse for a few seconds it corrects itself. There is one thing really ugly though. Because resolution is too low ( 1280x800 ) mouse cursor is too ugly. I didn't test it yet with external display.. I'll check it with my 4K TV to see if it's 4K capable.

I had to update Wifi driver though because it seems every OS X version has its own Airport itwlm driver.

Thanks for your comment. I'm neeby in OpenCore (I left the scene with Clover). Could you tell me the operations you have done for having a fonctionnal configuration please? I don't know OpenCoreConfigurator. What kext have you used?

Thanks for all.

I used entire EFI folder but removed some of the kexts about PS2 mouse/keyboard support.. I also upgraded all of the kexts to latest versions via OpenCoreConfigurator and replaced Airportitwlm.kext with Big Sur version. The steps I executed were as follows:

• Created installation media from my Mac ( Probably you know how to do this already )
• Mounted EFI directory and copied entire EFI folder from repository to the EFI partition.
• Upgraded OpenCore to 0.6.6 debug version
• Ran OpenCodeConfigurator
• Loaded config.plist from EFI/OC folder.
• In the Kernel section I updated kexts.. I downloaded Airportitwlm directly from github release page and replaced with Big Sur version.
• I executed GenSMBIOS to generate my own serial/UUID numbers and replaced the values in PlatformInfo
• Removed NvmExpressDxe.efi, Ps2KeyboardDxe.efi, OpenUsbKbDxe.efi
• I think we should check if we really need OpenCanopy. I plan to create a triple boot system so maybe I don't really need this. If that's the case we could safely remove Ps2MouseDxe.efi and UsbMouseDxe.efi
• There's a warning about SMCBatteryManager.kext.. I'll check the logs about this, because at boot time I get a lot of warning/errors that max capacity of battery is higher than what's given ( 5000 ).. It was around 5171 when I boot up.
• After saving changes and rebooting I first executed disk utility to create 3 partitions ( Because it's GPT, there's also EFI partition but it's hidden ).
• I set the first one as APFS, the second one to exFAT ( for Windows which I'll format it as NTFS later ), and a third one as MSDOS FAT ( which I'll use it later for Linux ).. Using disk utility when the screen is sideways is hard. Although you could do it if you use an external mouse.
• I started installation then. It rebooted a few times and finally booted OS properly without needing any adjustment.
• I rotated the display through Cmd+Option Display method because I don't want to use an external app for that.
• At login screen you have to move your mouse like crazy or tap your keyboard until the screen initializes correctly.. That's a weird bug, although at last you could see everything ok.
• In first few boots mouse cursor was pretty ugly. It was like interlaced or something.. But after a few boots it fixed itself.
• As you may know GPD's keyboard is pretty bad, I used my Magic Keyboard 2 + Magic Mouse 2 successfully.
• The trackpad itself is weird. Sometimes it detects right click for left clicks. It's better to use an external device. If you want to use it professionally use Magic Trackpad. I use it on my i7 hackintosh for development. BTW, sometimes trackpad acts like single touch, sometimes multitouch. It's weird that way.
• Touching the screen feels weird on OSX. It works for clicks or scrolling.. It's ok for scrolling I think but you should prefer to use a mouse or trackpad for sure.
• I couldn't use onboard controller though. There is a project 360Controller which gives XBOX 360 controller support to macOS, although it is not supported on Big Sur, and certainly causes problems on Hackintosh. I tried some hacks to enable it but after boot, it stucks.
• Airportitwlm works its' magic and you can use onboard wifi.. Although performance is abysmal. It only supports up to 802.11n, while the onboard card is 802.11ax. I connected to my 802.11ax router and saw 140 Mbps maximum at close range.
• I did use some USB3 devices successfully.
• As you know there are two USB-C ports on the GPD Win Max. I had a USB-C to HDMI, USB3, USB-C adapter. If I connect it to the middle port ( between USB-C and USB3 port ) it doesn't work. But if I connect to the left port it works even if I hotplug. It gives 4K output with HDMI cable no problem. I don't have a USB-C display so I don't know if it'll work directly from USB-C to USB-C. One important thing though. I cannot charge it from the adapter's USB-C port. If I connect charging cable there, display cuts off. I had to use the middle port for the power.
• I had also Lenovo Thinkpad USB-C Dock Gen2... This acts differently altogether.. While it works on the left port, there is no output from HDMI port ( didn't test display ports on the dock ). It charges and gives all of the interfaces on the dock ( USB ports, ethernet etc ). If I use the middle port, display works and it charges also. So it lefts one USB-C free for whatever you desire.
• Although even if I use the dock or the adapter it shows the external display as 5K display, and acts weird. There are intermittent glitches on the screen.. You can use all 4K resolution although it looks very tiny even on 65" screen. It's better to use 1920x1080 or 2560x1440 like resolution on 4K TV.
• Sleep works perfectly. I didn't have any crashes at all yet. Hope it'll continue like that.

So, I think it's pretty stable for now.. I use Zotac zbox mi572 as my development platform with TV. While it works with Catalina I didn't test it with Big Sur.. Also I couldn't get 4K output from it. It also can't wake from sleep. So it's not all good. Because I use it for production I don't want to test anything further on the machine.

GPD Win Max though works perfectly as your portable Macbook ( It shows 1,5 GHz Macbook Air ), and it's perfectly usable if you use bluetooth keyboard+mouse/trackpad with it. For now the keyboard is abysmal at best. I don't know how many times I pressed Q instead of that tiny Tab key. The "space" key also sometimes works sometimes doesn't. The trackpad is so so..

After all this, I'll try to install Windows and Ubuntu on other partitions and try to get a better boot screen than OpenCore's, because that's absolutely horrendous.
