Sounds like good news. There are many reasons why copy-protected CDs should never have been introduced, but this has to be the most serious:
"The Celine Dion CD released in the UK by Sony has caused major problems for Macs. We have heard of many reported problems with the new flat-screen iMacs, in which dealers had received machines to repair, only to find a Celine Dion CD inside and no other problems. With a Celine Dion CD inside, these Macs boot up to a grey screen, and will not respond, nor eject the CD. We have also heard about similar problems with a recent PowerMac G4 model. Apple have published a technical note on this issue. Note that Sony are still releasing new CDs in this format, so the Celine Dion CD is unlikely to be the end of the story."
