smallbearayu Posted July 14, 2019 Share Posted July 14, 2019 Hi,I've got a Mid-2019 Razer Blade with i7-9750H and UHD630 + RTX2070 graphics. It comes with 240hz refresh rate screen.I was trying to enable the UHD630 on 10.14.5 Mojave. The current problem is that I will get instant reboot when I set the platform-id to 0x3E9B0000 or 0x3E9B0009 or whatever possible value of Coffee Lake.The instant reboot happens after this debug line:IOConsoleUsers: gIOScreenLockState 3, hs 0, bs 0, now 0, sm 0x0I can only boot into the macOS when using 0x12345678 device-id but the graphic will not work under this id.I've set the DVMT-pre allocated to 64MB and this is the maximum possible value on my BIOS.Attached is my EFI folder. Any help appreciated.Thanks.
