    macOS + Win dual boot (at same disk) with OpenCore

    I recently set up a dual boot Catalina/Windows 10 system using @Maf3ro’s method but didn’t want to use Bootcamp. I found that after a couple of reboots between the OSs, Windows Boot Manager persisted and the only way to get into macOS was via the bios boot menu or USB stick. I then tried the...

    Problems installing Catalina 15.1 on Gigabyte Z370n WiFi

    With your EFI at long last I am now up and running! Thank you, you’re an absolute star. After doing some research prior to trying your EFI, I disabled the CFG lock in the BIOS - not sure if this would have made any difference. Thanks again!

    Problems installing Catalina 15.1 on Gigabyte Z370n WiFi

    I've spent the last few days trying to do a clean install on my Z370n build but to no avail (it had been happily running Mojave). The board has BIOS version F12 and am using the STAS.SSDT and DSDT RTC patch which I believe are required when using that BIOS. Internal intel graphics are enabled...

    On my set up I am running a VEGA 56 dGPU with the Intel UHD 630 iGPU in headless mode using SMBIOS 19.1 and with the Display Port, it works faultlessly. For various reasons, I'd like to use the HDMI output from the VEGA but when I do so, the display continually flickers on and off. I seem to...
