Apple Confirms It Is Investigating Issue With ‘Pink Squares’ Appearing on Displays Connected to M1 Mac Mini

An internal Apple memo (originally obtained and shared by MacRumors), the Cupertino firm tells service providers that it is aware of and investigating an issue several M1 Mac mini users are reporting where “pink squares or pixels” are appearing on displays connected to the Mac mini.

Several users have reported the issue, across the Apple Support CommunitiesMacRumors Forums, and Reddit since the M1 Mac mini launched in November. Affected users report the issue may be more common when connecting displays via HDMI compared to Thunderbolt.

The memo was issued on February 19, 10 days after the release of the macOS Big Sur 11.2.1 update, which does not appear to address the issue. While Apple has not provided a timeframe for a fix, one could be included in macOS Big Sur 11.3, which is currently in beta testing.

In the memo, Apple offered the following troubleshooting steps:

  • Put the Mac mini to sleep
  • Wait two minutes and wake the Mac mini
  • Unplug the display from the Mac mini, and then plug the display back in
  • Adjust the display’s resolution in System Preferences -> Displays

If the issue reoccurs after restarting the Mac mini, Apple says to repeat the steps above.

We’ll keep you posted if we hear more about a fix or when other information becomes available.
