Macworld has been swamped by calls and emails from worried readers, following our exclusive reports that initial shipments of Apple's new Power Mac G4 came loaded with older G3 chips (see news story).

If you are concerned, simply activate the Apple System Profiler under your Apple menu. This will tell you if you have purchased a G3. If you have, please contact us on [email protected] – as well as informing your Apple reseller.
