AFAIK, is rather the opposite: the "trusted" hardware (controlled by TPM chip(s)), can prevent "untrusted" software from running. Obviuosly, what's "trusted" is decided "high above" and not by the user.
Officially it's for safety purpose (isn't it ironic how much freedom and rights people let go, for the sake of so-called safety...? ;-)... As a matter of fact, it's more likely a way to control piracy and copyrights. E.g., one day you might discover your whole MP3 collection (legally ripped from your own CDs) isn't playing anymore, because they aren't "trusted" by music companies. Or, some software tool and shareware are blocked, because they aren't "trusted" (obviously, the process of "trusting" is complex and expensive, so only major software companies can afford it). > I know it's highly unlikely, but from a theoretical standpoint Apple > could "lockout" the owners of Intel Macs. Or, more likely, decide which programs/processes/activities are authorized to run, and which are "locked out". This has always been the main aim of TPM platform (at the beginning known as "Palladium", IIRC). -- You received this message because you are a member of G-Group, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.
