I was going to say "bingo!," and was getting ready to translate it to RB, but, oddly enough, this code does not appear to work as described. It says it returns //0 if the process is running natively on an Intel-based Macintosh computer //1 if the process is not native but running translated using Rosetta //1 if version of Mac OS X predates Rosetta, which means the process is native and running on a PowerPC Macintosh computer On a Power Mac, it gives: sysctlbyname_with_pid(0): sysctlbyname failed:No such file or directory is_pid_native(0) = 1 On an Intel Core Mac, where the program itself is running native, and process #495 is running under Rosetta, it gives: is_pid_native(0) = 1 is_pid_native(495) = 0 It would be very interesting to know whether this is just a bug (and whether the code was not tested), or whether something changed in Mac OS X between the time at was written and 10.4.7. SO far, haven't found good enough documentation on sysctl and friends to be sure! I realize I'm spending more time on this than it deserves... but I've got the bit in my teeth. Something else that doesn't work, probably to be expected, is the AppleScript "system info" command, because when invoked from inside a PPC RB application running in Rosetta, it itself runs under Rosetta, and it gets CPU type = PowerPC 7400. _______________________________________________ Unsubscribe or switch delivery mode: <http://www.realsoftware.com/support/listmanager/> Search the archives of this list here: <http://support.realsoftware.com/listarchives/lists.html>
