> 1. Does the security flaw affect OS X.1? I don't *think* so, but I may be mistaken. Apple is addressing a vulnerability that comes from using Safari (which was available for use only with 10.2 and better), though my understanding is that several other browsers are suceptable. (I suppose it would depend on how the "Help" system is set up in 10.1.) > Specifically, If we have 10.2.4, must we first upgrade to 10.2.8? *Probably* not; the reference to 10.2.8 was probably because it was the last version of 10.2, and the update may well work for earlier versions of 10.2. (But I don't know for sure.) BRIAN/bpearce at cloud9.net http://www.redjacketpress.com
