Firemonkey OSX client

[TeslaSistemi]

If possible, I would need an example code in firemonkey that implements a simple OSX client.
What I need is that through the "portal" of Windows to see the screen of an Apple OSX computer: that is to create a very simple "Support" (even without all the features of the "Support", just see the remote screen of Apple) .
Thank you
Fabio

Your question is off-topic, but ... if you are only looking for a place to start, you might find "RTC Portal X" source code useful (see link below). Even though it has been discontinued last year (there are NO WARRANTIES AND NO SUPPORT) and the version released on GitHub does NOT contain Example Projects using FireMonkey (only VCL), you should be able to find a cross-platform version of video encoder/decoder, as well as basic screen capture functions in its "Lib" folder:
