IIRC, being a heavy Samsung SSD and other memory user. You can't upgrade the firmware on a MAC. The ISO images were just CD images of the windows software to install the new firmware from. However that could have changed in the past few months, that said there is NOTHING stopping the OP from booting any Mac Compatible system as long as it is bootable. For example I can burn Linux to CD or DVD and boot all day long new versions of that OS to my hearts content.
All this to the side, if its not booting, its a UGE or something Samsung may have over looked.
But why would you want to update the firmware unless its not functioning correctly. If its new it should have the latest firmware anyway.
I have my Samsung 830series 256GB SSD and Apple 1TB HDD in a 1.25TB fusion array and it runs great. Highly recommended.. And BTW, I never had a reason to want or need to upgrade my drives firmware. It runs perfectly as it should.
