Upgrade Crucial C300 firmware on a MacBook Pro
I just got a Crucial C300 SSD to plug in my Mac. And it came in revision 02 ; but the latest bug free firmware is revision 07. To upgrade, just go to the Crucial website and get the “C300_FW0006.zip” archive. Unzip and burn the ISO file. Reboot, use ‘alt’ to drop to the boot selector and select the CD drive ; it appears as “Windows”. Let the process find your drive and upgrade the firmware to 06.
