WD20000D033 Mybook World Edition II blue rings Mac compatibility

Can I upgrade my Legacy Mybook World edition II blue rings to be mac compatible?

No, you cannot. 


Let me rephrase my answer.  We do not provide support for the My Book World (Blue Rings) network drive on Macs.  And, there is no update written for Mac compatibility.  However, whether you can get the drive to work on a Mac network is up to you.
