Unfortunately, very unlikely since it's possible to dual boot Mac Hardware with Windows using BOOTCAMP, and most X-Plane users are on Windows (65%).
Here is a video I found on the net, related to IXEG 737.
Note, late in the video, the user asks for speed to be set in MCP and it would appear FO not understanding it. In fact FO is type rated on aircraft, and would only set lower speed when flaps configuration is correct.
With 737, you go like this
Flaps 1
Set speed 190
Flaps 5
Set speed 170
Gear down
Optionally (Set flaps 10 followed by Set speed 160)
Flaps 15
Set speed 150
Flaps 25
Set speed 140
etc .....
In this video, user opted for JC French-Swiss accent. But there are 8 other co-pilots, including US, UK, OZ and German accents.
When downloading the Demo, don't forget to download all the other voice packs separately.
