Will simply checking NSAppKitVersionNumber from awakeFromNib in my NSApp delegate be sufficient? Can I launch a 10.3 or 10.2 app on 10.1.x, get to init or awakeFromNib to check NSAppKitVersionNumber (before any incompatible APIs are called), and if necessary, call NSRunCriticalAlertPanel then exit gracefully?

I'm pretty sure there's a reason, but I'm not understanding why weak linking or installing a small version-checking executable within a bundle is necessary to determine the version. I need to get this code properly working in my application. Thanks.

If you have weak linked the appropriate symbols then that is enough. At launch time the dynamic linker tries to resolve all symbols your app uses and if it finds a non weak linked symbol that your app uses it bails out,
