Screen Flickers after High-Sierra Update

I have this exact same problem. Just updated to High Sierra today because I heard it's the only version of MacOS that was patched for the Meltdown hack. Now the screen is flickering non-stop. I have a late 2012 macbook 13" retina

I'm contending with a host of High Sierra issues. It seems that the update includes some effort on behalf of Apple to limit the use of non-apple peripherals and connectors. So, for instance, you have to buy the $50 USB-C to HDMI connector from Apple now - they've disabled Belkin and everyone else's connectors.

I've got the flashing screen, too. Also, sometimes desktop icons for files appear over windows instead of behind them.

There's too many competing intentions here; I feel like we're watching a business model go out of control. Good excuse to try Microsoft Surface, I think.

Hmm. Your issues seem to be with the connectors used to connect monitors, along with other posters.

However, my display flickering issues are without any external connection. We're in feb now and it's been almost two months since I got this update and there is no fix from Apple yet. Ridiculous.

Unfortunately I am also experiencing random screen flickers on my MacBook Pro 15" late 2013 after high sierra upgrade. I am at version 10.13.1

I have another person in my team have the exact same problem after updating to High Sierra. Even worse. This cannot be a coincidence.

I have the same problem of flickering after the update. No solution from Apple yet?

Hugo

Have the same issue. So far I've seen it in these applications
- Safari
- Firefox

- Chrome

- Skype

It's a shame Apple hasn't fixed this yet. By far the most disappointing OS update for me.

Hi Andrew,

I have also noticed troubles in rendering fonts in the composing window on my 1984 mail webapp ;-)

I bought my MacBook Pro Mid 2012 non-retina new in 2014 I think. I care a lot for my electronic products to keep them in mint condition, save the box and so on. I have not any problem at all during these years. Until the High Sierra, with errors getting me to think "something is broken". Unfortunately, the problem is still there even after complete reinstall to El Capitan. I also noticed a spinning globe during a second or so together with some flickering thin lines. It also appeared during web surfing, however, thats what the computer is used to 90% of the time. The disk is an SSD disk.

According to my earlier post the problem was still left after reinstalling El Capitan. I have to admit, this seems not to be the case. The black screen that was seen now and then with High Sierra is gone. My wife experienced a black screen after re-install to El Capitan, and of course, complained about it. Although, I suspect that it was the energy saving that kicked in pretty fast since the values were reset during re-install. I usually change these values to something higher. The spinning globe I mentioned, I have no idea but probably not related. I set up my computer running from full battery and placed it at our dinner table, removed every energy saving setting and watched it during the whole day (well... not strictly speaking), now and then I used the web-browser and some applications. I couldn't notice anything strange during this time. My wife hasn't complained anymore about it. If only the Software Engineers had the courage to give the marketing guys the birdie when forcing a release of a not thorougly tested software.

I have the same issue and it seems to mostly happen when running safari. It's interesting that I also have Parallels installed though I still see the issue when it's not running. Parallels is mentioned quite often by others.

This update has been horrible. Besides the flickering problem, my system hangs almost every time I connect to an external monitor which is another problem often reported. I'm used to the occasional hiccups when upgrading but these video issues are beyond annoying and it's hard to believe they weren't seen during regression testing.

Have the same problem since install of High Sierra. Apple would under NO circumstances admit that the problem comes from the OS update.
