Normally the touch on mac is not supported as no mac product has the touchscreen. in my tests I noticed that generally if the cursor is placed on the external screen, all in all it works but I have not tested it in depth because I am not interested. some users have found it useful to install external drivers like those provided by touch-base.com
I have tested this with M3 MacBook Air on macOS 26.0.1 and get the exactly same behavior. The solution suggested by pippitto87 (with the cursor being on the external screen) does appear to work—this is good to know, thanks.
I have the monitor on a Raspberry Pi5. There the touch screen works perfectly and without interruptions. Therefore, I also think that it is due to the Macbooks.
I received this from Digitec today, and am generally impressed. When it's connected to my Samsung S24 phone, or Acer (Windows 11) laptop, it works brilliantly straightaway. With my MacBook Air (2022) though, it's a little strange. The display works fine, but the Touch part is odd.
Sometimes, I'll tap on the screen, and it'll work fine. Other times (with the same cable, same MacBook) the taps are completely ignored, and other times I tap on the screen, but my MacBook registers the tap as being on the Macbook Air's own display, rather than on the monitor, so the tap is registered in completely the wrong place.
Has anyone else had issues with using this with a MacBook ?
