![]() ![]() The firmware update process was handled in a NetBoot environment, as these machines are not T2 machines, and thus can be NetBooted. Now the machine was ready for the next step. Our friendly Genius also reminded us for the third time that all data should be backed up at this point, or forever hold your peace. After a brief check to determine OS level and functioning status, the machine was restarted, its PRAM zapped, and then it was run through standard onboard diagnostics (ie, hold Shift-D at boot). The Basics of the Solid-State Service Programīefore the process began, each of our machines was inspected and made sure to be in operating condition. Two of the machines failed the diagnostic portion of the firmware fix, and one was successful, which gave me a look at both cases of the SSD Firmware Update. In this case, I had three affected machines, and a Genius Bar appointment. Today, I got to watch as a technician completed this process on a client computer, and I wanted to catalog what happened, as there’s not a step-by-step guide available for admins. Where one does not exist, we will use Carbon Copy Cloner to backup to a disk image. In our case, where Time Machine backups exist, we will perform a final update to the backup before the machine goes in. ![]() Apple states: “Prior to service, it’s important to do a full back up of your data because your drive will be erased as part of the service process.” This means that you must backup the data before you take the machine to Apple. ![]() The Apple documentation for this repair is clear: the machine will have all of its data wiped during the firmware fix. Think of a service program a lot like a car’s technical service bulletin program: designed to identify a potential failing of a given make and model of machine, and resolve that defect before it turns serious. This Fall, Apple announced a service program for the non-Touch Bar MacBook Pros (also known as the MacBook Escape, for the hardware Esc key that they still have), specifically around the solid state drive that stores the operating system and user data. ![]()
