I connect 2020 Mac mini (Intel UHD Graphics 630 inside) with display monitor and test DDC/CI command.
The DDC/CI command can work well via Mac mini Thunderbolt port or Thunderbolt to HDMI adapter.
But DDC/CI command does not work on Mac mini "HDMI port" only.
Mac mini HDMI port does not send '6E' command ***** address in normally.
PS: The DDC/CI also can works well on 13" MacBookPro 2020 Thunderbolt port.

The DDC/CI application can work well on MacbookPro/Mac Pro (Big Sur), but it doesn't work on M1 Mac (both macOS 11.0.1 and 11.1). M1’s graphics card is Apple, not Intel or AMD. Does this incompatible issue relate with new graphics card or kernel change? Any alternative solution for M1?
Hi,
I'm developing a cocoa application that need to run a script when user enter login screen.
I'm thinking of using a daemon plist to to the job, but I don't know when to fire the script.
Do anyone know how to detect when Mac enter login page?
Thanks in advance.
