I am working on a finalized OpenCore version for our laptop. I will post the guide on my github not this website (for various reasons). I might finish it this week or the next one. No EFI will be provided but a guide with the steps to make your own following OpenCore laptop guide. Things that doesnt work as of yet:
- The Power LED stays blinking for whatever reason even if the _SI._SST has been properly called with `1` arg (no idea why, but will probably find a workaround)
- The battery duration on macOS is quite bad (like 4-5h at most), even if idle CPU power is under 1W (yes it will take 10h on idle, but what's the point?)
- TB3 will probably never work with hotplug (as far as I know, our chipset was never used on real macs (DHL vs JHL) and will only work on power on and that's it)
- I did manage to keep TB3 working after sleep and on power on with hotplug but you'll have to sacrifice USB capabilities on the those ports (probably ACPI related, as there is literally no code about companion ports in our ACPI tables for TB3, which is weird, injecting one would just rename the ports from generic names in IOReg to those in ACPI and that's it, it will still be broken on wake)
- I will probably not release this because it's all messed up and buggy but if you want it, open an issue (when the guide is up) and I'll throw in a post about it
- No physical display outputs from the laptop (HDMI/TB3/mDP) for one reason: all physical outputs are connected to the nvidia card which, you guessed it, is disabled and thus nothing will work from it (as it's incompatible)
- No, the Nvidia card will never work (the vBIOS is in the UEFI firmware chip and cannot be sideloaded and if it did work, it's only on High Sierra which by the end of 2020 will be discontinued)
- Hibernation not working yet (sleep does)
- DW1560 works (no BIOS mods needed)
- DW1820A works (with the aspm disabled as per this guide https://www.tonymacx86.com/threads/the-solution-dell-dw1820a-broadcom-bcm94350zae-macos-15.288026/(basically pci-aspm-default set to 0)
- Bt has issues
- any Apple 12+6 card will work
- Just for information, Lenovo removed the WLAN whitelisting, be happy about that
- No, WLAN on M.2 m/b slot (with adapter) will not work properly for whatever reason (also will throw an error on boot if it's not a storage device)
- Yes you will need an adapter like this one https://www.aliexpress.com/item/4000026569596.html (12+6 to M.2 a/b adapter with FPC/Flex cable)
- works oob on the wifi side, BT still needs the patchram kexts
- Intel wifi chips support may be coming soon™™™™™ (no promises, and it's not from me, but they're working hard on it)
