I was able to solve the problem with a "Gordian Knot" solution: I dismounted the boot drive, mounted it on another (actual) Macintosh by means of a USB/SATA adapter; used Clover Configurator to mount its EFI partition....and then simply replaced the files there with a backup I'd saved. Now it...

Apologies if this is the wrong sub-forum. My system has been working perfectly for years. I can think of no recent config changes except attaching and detaching monitors. Suddenly I'm getting this (see photo). Can anyone help? Thanks in advance for any advice anyone can provide. Jordan

I went into BIOS and turned off the serial port. No difference — the boot went through what appeared to be the same logging and then got to the black screen and then the gray screen, and froze. Thanks in advance for anyone's help or advice. As I said a few days ago, I'm in over my head and...

I see it but I don't understand. (Obviously I don't need to understand in order to fix it.) Thank you.

Thank you! It wasn't easy — I'm running Sierra, which can't deal with 60fps HEIF video, so I had to pull the frames on my phone. I'll try it! Thank you. This is what amazes me about all of you guys. How on earth could you possibly discern that, from that big glut of data? Where are you...

OK, I actually managed to retrieve the complete onscreen log, from after the OpenCore handoff and the boot selector right up until it goes to black and then to gray, and freezes. As I wrote above, I shot a 60fps movie — I extracted frames and matched them up into a single composite image (and...

Thank you very much. I've adjusted your EFI and now it almost works — I certainly get much further than I ever did before. Now, I get all the way to a solemn pause and then a uniform gray screen...and then it stops. From what I can see of the flurry of onscreen logging, it's getting all the...

I tried to use your version of the OpenCore EFI directory. There's a conflict: you have the entry for "XHCI-unsupported.kext" in config.plist but the actual kext isn't there (which means an immediate error is generated — see first photo below). (Obviously I'm not complaining! It's just an...

I can't thank you all enough. I'm away from my machines for the weekend but when I return I'll try to make more headway along the lines you've all suggested.

As I told UtterDisbelief above, I just don't have a firm enough grasp of the ideas involved, to translate all of this into a programmatic series of steps for getting the USB installer to work (and for solving subsequent USB problems, in the more forgiving environment of a subsequent Mac...

I'm sorry — this is going over my head. (I've been trying to keep up with the discussion of USB controllers, but it's very complicated, from a macOS standpoint, a PC standpoint, and a Hackintosh standpoint.) What exactly are you saying or recommending, procedurally?

Is that for a Clover config.plist or an OpenCore config.plist? (The link just goes straight to the download.)

So Plan A and Plan B didn't work, on all (or nearly all) the USB ports. I started over with a Catalina installer (using the makeinstallmedia script within the package to format the USB, etc.) and tried Plan A and Plan B with that new USB installer, in several different USB ports. Every single...

Plan B didn't work either (on two different ports). I'm starting to think you're right: the USB stick itself is somehow borked. I'm going to try making a Catalina installer.

"Plan A" — XhciPortLimit off + USBInjectAll.kext + SSDT-UIAC-ALL.aml — failed on every single USB port. One port gave a slightly different result: the scrolling log actually mentioned all the USB ports (although it was hard to read given the speed of the scroll). Nevertheless it failed. Now...
