black screen in Catalina

Everybody who has marked this issue as solved in other posts later posted that it wasn't solved. I've wasted hours trying every suggestion to fix this issue (reinstalling Catalina, resetting SMC and NVRAM, starting in safe mode, etc), all to no avail. Hopefully a bug fix comes out to address this soon otherwise abandon all hope.

Today I don't see getting around acknowledging that never letting my display go to sleep may shorten its life. Can't be much worse then just hard powering down my Mac with a handful of open apps. I guess if you walk away long enough to let your monitor go to sleep, you don't care what you come back to... Let's get this fixed MacOS Developer Teams, clearly a reported issue.

Yeah I certainly hope there is a fix soon, as the hard reset every time the screen is just risky and definitely not a long term solution. I was always worried about data corruption if I do a hard reset - just had to do a hard reset, and when my MBP boots up it gets stuck at the Apple Logo with the progress bar reaching the end (i.e. 100%) but my MBP is still not showing the login screen - have been like this for 5 minutes now so I’m kind of worried.

Hopefully Apple comes up with a fix soon.

I have the same issue, also when connected to 3 external monitors, I cannot get an image on one... when I close MacBook Pro lid I do get the 3rd external monitor to work, but since there is a forced sleep them wake up that happens, I can never use it as the hard lock requires a hard reboot. turning off sleep abilities is NOT a resolution for this... curing the symptoms of an issue simply mask the problem they do not solve for root....

I'm having the issue too. (2018 MacBook Pro 15") Never happened before Catalina. Hope they get a solution soon too, cause is very frustrating. :( Haven't done a Time Machine Back up to go back to Mojave.

Welp, guess Chrome isn't the solution.

This is also after my Mac coming back from a licensed Apple Repair shop and they still couldn't resolve the issue. They replaced my entire battery and front panel (not related to this) and still no solution. Reset all the same things mentioned and chimed that they believe it to be a software issue.

Not sure but there is a bug in this software that I am hoping someone is working late to have a fix. Give them a beer when they do.

I have to do the same thing too - turns out the MCTTriggerGraphics.plugin and Trigger5Core.kext are the culprit, and I can even put them back after restarting - the moment I put the back the issue came back.

I remembered at some stage I used a USB Video Graphics adapter from j5create and must have installed one of their drivers then. A search on their website indicated that their Mac drivers are not fully compatible with Catalina yet and they are asking people to delay upgrading to Catalina.

As I don't use either of those devices now I am happy to remove those drivers.

Hopefully my MBP would now stay this way and all will be OK...

Thank you to whoever found this solution/workaround.

Well after 10 years of using Iphone I now switched to Samsung.

As my laptop keeps crashing even after beta 2 "upgrade" it's clear Apple is not what Apple used to be.

So time to buy myself a Microsoft laptop.

Thank you so much - this finally fixed the problem on my two MBA. I put the files back in to /Library/Extensions folder, and continued to have no problem. Such a dream not to have to shut down the computer and restart every time I walk away from it.

Thank you to whoever did the hard lifting to find the solution to this.

I'm experiencing another issue related to Display.

I own a MacBook Pro 2019, and attached an external monitor via USB-C. When I first attached it in my MacBook (Mojave) it worked like a charm, then I upgraded to Catalina and experienced the black screen. Now I downgraded to Mojave and the black screen stoped but when my Mac return from sleep, the resolution in external monitor is completely messed, something like 1280 x 720, then I have to open the lid of my Mac and close it again to return to best resolution.

My external monitor is a Dell P2719C, whom used to work very well.

Fair enough and agree. The wording "exact" was more meant as response to the earlier contributor appzattak, as his method solved it on our side as well, compared to all the other tips and tricks which did not solve it. Curious if we ever hear about the root cause of this annoying problem...

Same issue here. I don't have MCTTriggerGraphics.plugin and Trigger5Core.kext in extensions tho.

The funny thing I noticed is, when the screen is "black", you can actually hardly see the windows are displaying, just very very dark.

Technology News is a driving force of any country's economy. It is important to stay updated to the latest technology news and developments that can impact human lives. Countries spend millions of dollars on emerging technologies are far ahead than

those who don't. It's important to stay updated with latest technology news so that we know where is our hard-earned money going.

What is 5G technology is quite simply put, a modern breakthrough in communication technology. Not only does 5G brings speed improvements over 4G, but it is also expected to unleash immense internet of things (IoT) potential throughout the

world as it is supposed to serve as the communication channel required between billions of connected devices communicating with each other. This is made possible with its reduced latency, higher communication speed but at a higher

cost.

yes i am going to use my time mach to restore back to before i updated . going to have one machine running mojave’s and one catalina

hope a fix is in the works

Same for my MacBook Air (13-inch, Early 2015).
