Your first post indicates you are still in the process of installing Mojave. When you start the computer, do you press F12 and choose the USB disk? Then select:Rx580 connected hdmi out - the message and screen lost signal ... 8 pins disconnected hdmi gpu out same message and screen lost signal.. i used mojave 14.1.0 with unibeast
- Stage 1 Installation: "Boot Install macOS Mojave from Install macOS Mojave"
- Stage 2 Installation: "Boot Install macOS Mojave from Mojave"
- Search this forum for "gIOScreenLockState". If no helpful solution, then try #2 below.
- Start again from Stage 1. Follow METHOD 1 of my Build Guide. But the guide is for Designare board so be careful if you have a different board!
