Please give us more details, about the bootloader, perhaps a photo with the installation menu, what kind of format have you chosen for partition.

The second video is with Micron SSD on the MB socket. I am not a cheater. The wifi card is replaceble, not embedded on CPU chip. It's obvious the difference between the 2 situations. VID-20200531-WA0000.mp4

Some proofs - first video without ssd on the socket. The img file is a screen shot made just before laptop shut's down. As you can see it pasts the IOConsoleUsers. VID-20200531-WA0001.mp4 socket

I'll try to make a video file with my attempts! Thank you again !

It's strange, my wifi card is not embedded in cpu chip, I already replaced it with an BCM 4352z (lenovo edition), as you can see in the photo.

Thank you for the link's you posted. It seems ardentwheel had the same issue as me. It 's possibile to load here videos?

I saw that, and I didn't understood why he deleted the page, I told myself that is possible some theory of conspiration haunting their heads. More than that I've noticed a totally silence regarding the subject and I asked myself "what is happening bro?"

I also installed the last Ubuntu but didn't experienced the problems you said, and overall I've installed macos Mojave (QEMU- virtual machine) on ubuntu but I was not satisfied about the graphic acceleration.

The efi folder I used on external SSD was the first I posted on page 8 and the outcome was at img. 126. After that I put back the nvme SSD Micron on the MB socket. I've booted again from external SSD several times (of course with different config.plist settings) and the outcome was the same - indicating some problems with the graphic card settings. Last time I booted from external SSD the system crashed at the point presented in img. 127. After that I attempted to bot from USB installer and the result was similar - img.127. This is the whole story of my adventure. This drove on the conclusion that something is wrong with the internal Micron SSD. Perhaps I'm wrong but I have have no more ideas. Alessandro or Gengik84, what's your opinion?

Replace the ssd card from it's socket and try to boot without SSD. This was the method that drove me to overcome the PCI configuration error. Before that the boot behaviour was identical with Alessandro's. From other hackintosh I cloned the macos Catalina system on an external SSD and after that, attempted to bot (via USB) on Yoga S740 ( with the Micron SSD 2200 out from the socket).

I read that the black Western Digital SSD' s (such as WD SN750 black), are macOS compatible. I am not sure about the blue models, probably they are not.

It may be this Western Digital SN520 NVMe SSD 256GB (SDAPMUW-256G)

boot in windows, enter in device manager and take a look

what ssd do you have?

I have to make a correction. The esp folder posted before is from an external ssd with Catalina 10.15.5 already installed on it. The outcome on image 126. The usb installer has the efi folder on efi_usb.zip and the outcome in image 127. As you can see there is some progress but I am blocked here. Have anybody some ideas to move further with this attempt or all of you are in coma? EFI_usb.zip

If anyone want's to try, here is the ESP folderESP.zip

I've tried with Catalina 10.15.5 and Clover. The boot gone further but stoped with cpu panic ....some IONVMe error. I guess it's related on Micron SSD card, I presume it is not accepted by osx.

Have somebody get any progress? What's going one with this silence?
