I'm curious — what are you recommending that costs $35? I know there are software packages (some free) that reroute MacOS's lust for temperature information into using less proprietary information sources, but I wouldn't suspect they would make HS happier (much the reverse). You mention an Inline Thermal Adapter, but my understanding is that this line of iMacs used several different models of drive, the proprietary cabling was different for each brand, and they are not available from graymarket parts sources (am I wrong?) _______________________________________________ MacOSX-talk mailing list [email protected] http://www.omnigroup.com/mailman/listinfo/macosx-talk
