Anyone know where I can get ahold of Apple hardware diagnostic software? And am I correct in assuming that this diagnostic software is not released to consumers, but only to authorized techs? If that's the case then I probably need to find a copy on a 'warez' site or usenet group. I don't frequent such places and suggestions would be welcome, if that's where I'll need to look. Also, the machine I'm having trouble with is a Yosemite G3 tower, shipped with OS 8.6 (I think) but now running 9.0.2. Would a current release of the diagnostic software cover it, or do I need an older, hardware-specific version?
