I have mini late 2006 1.66ghz 2gb ram installed at apple store same day on march 14 2007 when I got it. I lost the original restore discs so I ordered new ones from apple. Finally got it to work and boot apple hardware test. My internal is shot and keeps spitting out discs. But my generic firewire external worked to run apple hardware test. Anyhow onto the problem. Hardware test doesn't boot. I just get this memory leak error after the apple hardware test logo. Please see attached photo. Anyhow I have 10.6.6 installed now. Not the original tiger. And all I do is web browsing and email. Nothing too heavy. And so far no errors. Should I be conserned or just let it go??
