Hello,
I am looking for a way of finding out what processor my app is
running on.
On PPC macs, there is no problem, it is the Intel mac that I was
wondering about. I have tried using the System.Gestalt call but
that always returns a G4.
Apparently under emulation, an Intel Mac will always return a G4
as the processor.
Therefore, I am looking for a way to detect if my app is running
under Rosetta and then I know I am on an Intel mac.
Does anyone have any ideas?
Yes:

However, I don't think anyone has ported it to REALbasic. The
declares shouldn't be too tricky, though.
They aren't; here's a port.
Function IsRosetta() as Boolean
Soft Declare Function sysctl Lib "System.framework" (p1 as Ptr, p2
as Integer, p3 as Ptr, ByRef p4 as Integer, p5 as Integer, p6 as
Integer) as Integer
Const CTL_HW = 6
Const HW_MODEL = 2
Const Null = 0
dim mib as new MemoryBlock(8)
mib.Long(0) = CTL_HW
mib.Long(4) = HW_MODEL
dim model as new MemoryBlock(32)
dim len as Integer = model.Size
dim theResult as Integer = sysctl(mib, 2, model, len, Null, 0)
Return (theResult = 0) and (len = 9 and StrComp(model, "PowerMac",
0) = 0)
End Function
Perhaps some of you could test this on your machines.

Sorry Charles, tried it with this code in a push button:
If IsRosetta then
MsgBox "We're working under Rosetta!"
else
MsgBox "We're not working under Rosetta!"
end
but it replies that "We're not working under Rosetta!". I've asked my
sister to check it on her mac-mini (G4) and she reports to see it
returns the same answer.
