Good suggestion Andreas. I've found the problem. It slipped my earlier observations that whenever i ran the SDK deviceQueryDrv, the clock rate was always displaying as "0.0 Ghz" and it didn't occur to me that my Mac Book Pro (has 2 GeForce cards - 9400m and 9600m) was choosing the 9400m low powered chip and for some reason the 9400m device wasn't returning properly but i dont know enough to know why this is occurring
Is this a bug with nvidia or with mac os x?
