[HELP!]Lenovo Y7000: IONVMeController Panic (10.14.3 on 860 EVO)

[formerkever]

Hello everyone. After the assistance of several pros on Github, I have successfully installed 10.14.3 on Lenovo Y7000 and all the features work perfectly EXCEPT one undocumented problem: random panics about IONVMeController. Sometimes it happens within 2 minutes after booting, sometimes longer, but sometimes it does not happen at all.

I have tried:

• reinstalling OS (doesn't help). However, the installation has no problem at all. It only happens when I get into the system.
• rebuild/repair cache using kext utility (doesn't help). It does make booting faster, though.
• move & install kexts (except FakeSMC) to Library/Extensions using KCPM. Doesn't help.

Since the laptop's original disk is a 512GB PM981, I have to install Mojave on a 860 EVO SSD, and I put it into a "drive box" so that it can be used as a USB external drive. In short, the system and the EFI are placed in an external disk. Does the problem has anything to do with the SSD drive.

I have tried several configurations and found the current one the most perfect, while the other configurations don't have this particular NVMe problem at all. So I think I can actually modify the DSDT to solve this problem. However, I have no idea because the guide post doesn't seem to have a solution for this NVMe thing. Could you please help?

I will be more than grateful for your help!

Have the same laptop my ssd Samsung model : MZ-VLB5120 PM981 and I faced the same issues.

how did you solve the trackpad ?

Here’s the best solution I have found

xiaoMGitHub/LEGION_Y7000Series_Hackintosh

适用于 Lenovo LEGION Y7000/Y7000P-2018、Y7000/Y7000P-2019、Y7000/Y7000P-2020、Y9000K-2020 系列安装 MacOS（支持MacOS 10.13.6 - MacOS Big Sur）For Lenovo LEGION Y530/Y540/Y545 series and legion 5i/legion 7 install...

github.com

However, Y7000 has several different trackpad models. For 2B46, you do not need any pinning. Just install the kexts and the trackpad will work perfectly. Not sure about the others.

And yes 981 is the major issue but I haven’t figured out why 860 evo doesn’t work. I mean, a lot of people use 860 and it’s said to work fine...
