When I open my system profiler I only get the Network and Software Tabs. The hardware tab is missing Also, I installed Onyx to see if I can get the information through a 3rd party program. Amazingly, the information about my Mac in Onyx was blank too. I am running Snow Leopard on a Unibody Macbook 2ghz Intel Core 2 Duo (the aluminum Macbook before they started calling it a Macbook Pro). I can't find any references on this problem and my system is otherwise running well. Any advice would be greatly appreciated.
