Where to get "System Events 1.2"

Can anyone tell me where can I get the “System Events” version 1.2

You mean for Jaguar?
You have to install it from the devtolls cd 2002.

In Panther, System Events is installed by default.

It’s located on both systems here:
/System/Library/CoreServices/System Events.app


Thanks a lot for that reply!. i have downloaded it.
