MacBook Air Black Screen after macOS Catalina Update

Just updated my older macbook air to macOS Catalina and upon restart my screen is black. It wont respond to anything. The only thing that happens when I hit the power button is the fax starts to run. I have tried to reset the NVRAM and the SMC. I've tried to boot into single user mode and into recovery mode. I even opened her up and disconnected the battery and display cable and reattached both. Nothing but the fan. How does an OS update do this? I am open to any suggestions.

I have replaced both the battery and the keyboard myself but everything was flawless for 6+ months until the macOS Catalina update...

If you're having the black screen issue when you lock your screen/when trying to wake it up, you can do this workaround I figured out: https://discussions.apple.com/thread/250719662?answerId=251378320022#251378320022

How were you able to determine the unidentified authors? Were you in the extensions folder?

Apple's tech support is actually scheduled to call me later today to learn more about the issue I had with my specific build of Catalina OS. I'll keep you posted on any developments.

Even though Catalina disables 32-bit apps, I found (on my second try) that it was better to remove them and any non-apple extensions before upgrading to Catalina.

What I am curious about (I too have a black screen after Catalina) is how to access the areas for kernals etc when the screen is black and nothing works

I have the same problem.

After updating Catalina, my MacBook Pro was left on a black screen. Apple support could not solve the problem.

I've been with a paperweight for 1 month.

Why isn't this problem getting any coverage in the media? It's like it doesn't exist and Apple doesn't care.

I am facing the same thing. I have a Macbook air early 2014 model, 8GB Ram and 256 HD. Every time i have upgraded the OS this happened, not just Catalina.
