Hi !

• there is a memory issue with the macOS app (continuously eating up the memory), possibly running into crash anywhen.
• and mac app is also continuously tracing out some errors :

entered processFrameAndSendTCP
Error: Could not extract an ImageBuffer from the SampleBuffer.
Failed to convert sample buffer to data

• there is absolutely no feedback to the user on the macOS side, whether creation of virtual displays was successful or not. as the virtual displays are invisible, there should be some indication.

• there is an error if one tries to create virtual displays repeatedly. it should actually keep track of which displays are created already and for instance disable these buttons. stopping the virtual display is not possible too...

• there should be some handshake mechanism, because it is not obvious why one must connect in a certain sequence. tried several times with no success because the order of logical activation was wrong.
