In an internal memo this week, obtained by MacRumors, Apple informed service providers that it is aware of and investigating an issue that may result in pink squares or pixels appearing on displays connected to an M1 Mac mini.
This issue has been reported by users across the Apple Support Communities, MacRumors Forums, and Reddit since the M1 Mac mini launched in November, but the exact cause is unclear. Based on comments from affected users, it appears that the issue may be more common when connecting displays via HDMI compared to Thunderbolt.
