Yes, Apple Silicon (M1, M1 Pro, M1 Max, M1 Ultra & M2, M2 Pro, M2 Max) Macs are supported, and can control external display brightness, contrast and volume using DDC. You can also use DisplayBuddy to adjust the iMac screen brightness or the Apple Studio Display / Pro Display XDR Brightness.

Note: DDC on the HDMI port in M1 Macs doesn't work yet, because it doesn't forward DDC commands to the display for a currently unknown reason. Displays connected to the Thunderbolt / USB 4 ports work fine with DDC, and the HDMI port of M2 Macs also work fine.

I sometimes work during the night, and I don't want my two monitors at full blast hurting my eyes in dim light. I use DisplayBuddy to quickly switch my displays to the correct brightness without physically touching the buttons on my monitor at all.

You can use DisplayBuddy to effortlessly increase brightness or dim your macbook screen and external monitors. The app can easily handle adjusting the brightness of multiple displays at once, and is a great tool to adjust the brightness of a second monitor on Mac. A lot of users also use DisplayBuddy to easily brighten their screen based on the time of day to reduce eye strain.

A lot of monitors have built-in presets for brightness and contrast, like Game, Movie, Reading etc, which lock your monitor's brightness & contrast to predefined levels. I highly recommend you set this mode to Custom, so that DisplayBuddy can then control these values.

Some monitors also have a DDC/CI setting: make sure this is set to enabled. You can find more troubleshooting steps here.

Yes! DisplayBuddy is also available on Windows.
