Detecting if a Mac is using Apple Silicon

Targets macOS
6

I created this method based on a Shell. It works whether the app itself is translated or not.

Function IsAppleARM() As Boolean
  #if not TargetMacOS then
  
    return false
  
  #else
  
    dim sh as new Shell
    sh.Execute "/usr/sbin/sysctl -a | grep 'brand_string'"
  
    if sh.ErrorCode <> 0 then
      dim err as new RuntimeException
      err.Message = "Could not run sysctl"
      err.ErrorNumber = sh.ErrorCode
      raise err
    end if
  
    dim result as string = sh.Result.DefineEncoding( Encodings.UTF8 )
    return result.InStr( "Apple" ) <> 0
  
  #endif
End Function

(Note: This intentionally uses API 1 calls as it is in freeware meant to work in older versions too.)

Edit: Removed “M1” from the search string based on Christian’s suggestion below.
