My machine: 17" 2.33ghz mbp. After installing Snow Leopard, when trying to calibrate the screen it gets to the end and then reverts back to the ****** default snow leopard calibration and says: "An error occured. The new calibrated display profile could not be created or set to be the current profile for this display." also, i noticed they spelled "occured" wrong. It should be "occurred" no? any of you guys have this issue? and if so, how do we fix it?
