Re: Update Firmware on M4 SSD on Macbook Pro without optical disc?

HI there,

 

I solved this after coming up against the same problem. I followed your tutorial (and the one you link to) to make the partition on another drive in my macbook pro 15" (2012 model) used a newer version of the required software. I've documented what I did on my blog here.

 

Hope this helps someone.
