Why is my screen flickering with this new macOS big sur update? I have a 2020 macbook air

TANGENT:

I have looked into this so many times and ran all the necessary checks ,and nothing. Not even the staff at my local apple store knew. They said it's because Netflix won't run properly on drivers that need updating and Netflix says the same thing.

I also have a MacBook Air 2020 and I think you'll agree the reasons are BS.

I'm putting it down as a faulty Mac and they don't want to admit it. I bet my suss will be confirmed in the future just as the 2017 and 2018 editions were faulty and didn't tell their customers.

Same here. 2020 MacBook Pro running Big Sur 11.2.3. I have connected a 2011 27" Apple Cinema Display for my video editing. Apple doesn't make an adapter so I have to use an UpTab brand adapter from Amazon. At first I thought the adapter was causing the glitch so I ordered a new one. Issue still persists. This is my work computer and I need it to work correctly! My 2015 MacBook Pro worked fine besides being slow and having a severely bloated battery and warped casing. Hopefully this is just a software issue and next update will fix. I'm currently updating to Big Sur 11.3 so we shall see.

I have had the same issue since I updated to Big Sur 11.3.1. I too have tried restarting in safe mode, NVRAM and also SMC. Everything worked for a little bit and then the flickering came back. Has anyone succeeded in fixing this?

Mid 2017 2.9Ghz 16mg Ram 1TB. I upgraded to Big Sur last night today my screen looks like it has double vision, or I am looking at a 3d film without glasses. It seems to come and go. Tried the zap P-Ram, Reset SMC, and Safe Mode. Still happening.

Flicker problem drove me batty just today! 2018 15" MBP2.9GHz i9 32 GB DDR4 w/ LG 5K 27" monitor running Big Sur 11.3.1. Found a solution but not sure why it works or if it might cause trouble later. Opened the MBP cover and, in clamshell mode, I get zero flicker over past hour!! Haven't yet tried the MBP w/o external monitor, but never had flicker that way before.

Does this fix make sense to those more knowing than I?

Is there any downside to my MBP by running it cracked open when I need the external monitor?

Thanks & hoping Apple peeks in to see this.

I have similar issue on both of my iMacs with Big Sur 11.4 while External 4K dell screen is connected. No issues yet when using standalone!

I have a workaround that might help others as well.

I've noticed I mostly (or maybe only) have this problem while using Safari and Webkit applications! such as Appstore, Xcode etc.

As a workaround close all apple applications to avoid Webkit and use Firefox instead of Safari and let me know if this helps you or not!

I believe people who still have Apple support should raise that and notify Apple team at first place.

You can also report the issue through "Feedback Assistant" on your mac.

Hopefully Apple will fix this problem in coming updates!

Cheers!

Hi,

Same issue with a 15" 2017 MacBook Pro. It didn't happen on the first day after the update, but is pronounced now. Very annoying!

Any update how how to fix it any one ?

• PRAM reset
• SMC

None worked.

Hello,

Same issue with MBA 2020 (i3). when I watch something on Apple TV+ (with the Apple TV app on Big Sur), my screen is flickering and blinking. happens also on YouTube (with safari).

Hi,

same with my screen (I have MacBook Air 2020 i5)! I can even see black squares on one part of it when the glitch happens. Hope the next update fixes this.

I run iMAC 2015 27" and the screen flickers on big sur update. Help?

im too scared to follow them rules im not sure what SMC or NVRAM, won't that delete things?

Don’t worry about that right now. Just try turning off and unplugging for a minute and connect and restart. See if that works first. But no, Apple isn’t going to recommend deleting important stuff.

I have tried all of these options and checked that all my software is up to date but nothing has worked, it is still flashing.

I tried all of these on the MacBook Air 2020 edition. Nothing happened. No changes. The red flicking still appears.
