Wow - very mysterious then. Cheers and thanks again for your help!

Hmm, so I deleted the NVIDIA web driver and on reboot I had no working display again despite the display being attached to my AMD RX 580. Rebuilding the cache did nothing. Glad I backed up the system first, will be reverting to that!

And actually, I didn't even do a clean install this time either. I didn't install to the drive I erased that I had intended to install to. So the only thing different with this install was the AMD card was present for the install. I guess that means the AMD kexts aren't installed if a AMD card...

Alright - so I did a clean install and I'm all good now. Sorry, guess I should've tried that first before asking for help. But I really appreciate everyone's help, thank you all! Thanks. I nearly have it memorized now! :D

Weird - because it fixes it for me, and was what the "solution" I found for it here on Tonymac. Interesting. And that should work with my X99 mobo? Hmm, I had just completely cleared out my bios when I upgraded the firmware. I guess I'll try as you suggest if I can't get this clean install...

Actually the final message is: Still waiting for root device

That is actually what I am trying right now. ;) My installer that worked before (with my nvidia card installed) is now hanging on the message: matching deferred by iousbhosthiddevice Trying to figure that out now...

Thanks for that. I noticed you removed SSDT-EC.aml which is needed to prevent APFS from hanging with the error: apfs_module_start:1683: load: com.apple.filesystem.apfs, v1412.41.1, apfs-1412.41.1, 2019/10/21 I went ahead and gave it a shot anyways, but it did hang there. How strange that its...

Sorry - I have a RX 580. Just seems very similar... But, I was thinking that link was about the RX 570 - it's the 5700, so probably not all that similar.

Thanks! Gave it a shot and same thing though. I tried both HDMI ports and both DisplayPorts. I wonder if this has anything to do with it, they say their Sapphire RX 570 was working until the 10.15.1 update (which is what I am running): 10.15.1 | 8GB Sapphire RX 5700 XT Nitro+ black screen

Thanks for your help. The signal works through the Apple logo loading the progress bar, but the signal is dropped once the system would normally show the login screen. So weird that it should work and doesn't. I just tried removing nv_spanmodepolicy=1 with no effect.

I updated my X99 system from High Sierra to Catalina running a Nvidia 1060. The display worked fine in Catalina, but without graphics acceleration of course. When I found out that there are no Nvidia drivers for Catalina, I bought Tonymac's recommended Sapphire RX 580 Pulse. I thought I was...

Thanks for your response (and guide BTW)! Do you mean in the System Preferences? If so, in Energy Saver, I have disabled Computer sleep but I have the Display sleep set to 12 minutes. Put hard disk to sleep when possible is checked and Wake for Ethernet network access is checked.

I followed this guide with a ASUS X99-A II, i7-6850K and GeForce Titan X (Pascal). I've been up and running for almost a week now, without a single crash or kernel panic. Running 10.12.5. However, every now and then the entire screen will freeze for maybe about 30 seconds (all updates such as...

What mobo/CPU did you use for the build? Your signature shows an Intel I7-7700K which I am pretty sure doesn't have 8-cores! :)
