I have a MacBook Pro 2.3 GHz Intel Core i7 (mid-2011 model) running OS X 10.8.2. I upgraded to an SSD which I bought from Crucial and works just great. Crucial sent an email recommending I upgrade my firmware to get even better performance from my SSD.
I downloaded the firmware to my desktop in the form of an ISO file from the Crucial website, and the instructions told me to burn this to a disk and change my boot order in order to boot from this disk. I burned the disk but subsequently have not been able to get a bios screen or to be able to boot from the DVD I created. I have tried holding down the C key but nothing seems to happen.
What do I need to do to complete the installation of the firmware?
