Apple Studio Display issue with colors


Hello dear community!

After the upgrade to MacOS 27 i'm facing issues with my Apple Studio Display 27, all the colors are over saturated, dark details are not visible and night shift is a mess (screen shot). Changing color profiles, settings, resetting display doesn't help. If is transfer app window on ipad as second screen everything is totally fine, colors are normal. Any ideas what is wrong with the Display? Thank you!

Hi there


Please try this

Sometimes updates inadvertently alter fine-tuning sliders in the Accessibility panel, which completely blows out colors and hides shadow details. 


  1. Go to Apple Menu  > System Settings > Accessibility > Display.
  2. Look at the Display Contrast slider and ensure it is perfectly centered at Normal. If it has shifted even slightly to the right, it will violently crush your dark details and heavily oversaturate everything.
  3. Make sure Increase Contrast is toggled Off. 

3. Trigger a Color Engine Reset via "Invert Colors"

If the color pipeline is locked up, a quick UI trigger can sometimes force it to snap back to normal.

  1. In the same Accessibility > Display menu, toggle the Invert Colors switch on.
  2. Leave it inverted for a few seconds, and then turn it Off.
  3. This forces the display controller to fully recalculate its current color mappings and can clear stuck rendering loops.

Hello Nick, thank you for the reply.

I've tried these steps with no luck, unfortunately.

What I've noticed that after the computer restart colors are back to normal for 20-30 minutes, then they get back to these over saturated black and red. I don't change any setting during this period of time.

Behavior changed after the upgrade to MacOS 27, could it be a bug?


Thank you.

Unfortunately none of these steps helped. Display firmware is 26.4. no updates available so far.

Update to MacOS 27.0.1 also had no effect (((

macOS 27.0.1 was issued solely for a zero day exploit patch that Apple suspected was being used in the wild, nothing else.
