While I maxed out on the RAM (a whopping 512MB), as it&#x27;s one of the first clamshells it&#x27;s limited by a 300Mhz processor. So no OSX for me. I don&#x27;t mind, it&#x27;s on 9.2 right now, which is about the most stable as they come. And with my homemade ssd (CF card with IDE adapter) it&#x27;s blazing fast!
