There are a few issues here, so listing them out. 1st, my configuration Sever runs on macOS 10.13, resolution 1368x768 with second monitor positioned above with resolution 1920x1080. Client runs on macOS 10.14, otherwise same configuration with second monitor above. Issues are as follows. 1) Not really an issue, but noting that if mouse dragging is enabled I have to drag from the second monitor to the across client machine. 2) If setting mouse mode to relative coordinate mouse, the mouse becomes trapped on the client side 100% of the time. No other issues, returns to the sever with hotkey. 3) If setting mouse mode to absolute coordinate mouse, the cursor can move back and forth between machines, but move a few pixels into the client machine and gets stuck (cursor will not move). 4) If setting mouse mode to absolute coordinate touch device things work really well except I cannot move the pointer up to the second monitor on the client machine. Without the external monitors, setting to absolute coordinate touch device works perfectly (with mouse pointer moving back and forth correctly).
