Hello, I just noticed that the Crucial support site has an update of the M500 firmware to version MU03. I wonder if anyone has successfully updated theirs directly on a Macbook. There are some posts on the Crucial forums with people not being able to boot the supplied ISO image off an superdrive or USB stick. I do not much care for the idea of moving the SSD to a Windows computer just to do the firmware upgrade. Mine is a 2011 Early 15 MBP.... Thanks for any info, Paul.
