While adding joypad-movement to my game I've discovered, that JoyCount() can only detect one new connected joypad on OSX. Disconnecting a joypad will not have any changes in JoyCount too. It will be shown as present.

Test-code by Yan:

SuperStrict

Graphics (800, 600, 0)

Repeat
	Local joyNum:Int = JoyCount()
	Cls
	
	If joyNum
	  For Local thisPort:Int = 0 Until joyNum
			Local joy$ = JoyName(thisPort) + " on port " + thisPort + " = "
			DrawText joy$, 0, thisPort * 14
			
	    For Local thisButton:Int = 0 To Int(Log(JoyButtonCaps(thisPort)) / Log(2))
	      DrawText (JoyDown(thisButton, thisPort), (TextWidth(joy$) + 1) + (thisButton * 24), thisPort * 14)
	    Next
	  Next
	Else
		DrawText ("No Joypads available", 0, 0)
	EndIf
  
  Flip
Until KeyHit(KEY_ESCAPE) Or AppTerminate()
End

Digging a bit deeper into pub.freejoy I've found, that in freejoy.macosx.c at the following code-lines:

int JoyCount()
{
	if (!macjoycount) InitMacJoy();
	return macjoycount;
}

... macjoycount will only change its value, when its 0. Connecting a second or third joypad would probaly not work too.
