I didn't find any direct way.

You can check whether an accelerometer is available:

B4X:

Private Sub IsMotionSupported As Boolean
    Dim m As Motion 'iPhone library
    m.Initialize
    Return m.As(NativeObject).GetField("accelerometerAvailable").AsBoolean
End Sub

There is a class called NSProcessInfo (Obj-C) / ProcessInfo (Swift) that has a boolean var called isiOSAppOnMac. Based on Erel's answer, it doesn't sound like it's implemented in B4i though.

You can access all APIs in B4i. Similar to JavaObject in B4A / B4J.

Something like:

B4X:

Private Sub IsAppOnMac As Boolean
    Dim ProcessInfo As NativeObject
    ProcessInfo = ProcessInfo.Initialize("NSProcessInfo").RunMethod("new", Null)
    Return ProcessInfo.GetField("isiOSAppOnMac").AsBoolean
End Sub

Note that it is only available on iOS 14+. What is the output of:

B4X:

Log(Main.App.OSVersion)

on the Mac?
