    Mojave 10.14.4 Boots to black screen with headless UHD 630 and RX 580

    Is the patch Plugin=1 in clover ? Can you have HWP after removing it? Another question maybe slightly off topic. When you changed your WiFi card, is there a warning message Everyime when you boot up ? Also did you have trouble with Bluetooth in windows sometimes?

    HP Spectre x360 w/ i7-8550U... Compatible?

    I have a coffee lake version of the 13 inch x360. Everything is working for me now. The only exception is the TP3 which I don't have a need for it yet. So I would definitely say go for it. I have the i5-8250U and 1080p version. But I am quite sure i7 or 4K screen should work.
