- Apple Support shows newest firmware at
IM41.0055.B08 (EFI 1.1). Need to investigate alternative methods for running firmware update.- My current theory is that OSX doesn't like the notion firmware updates using an external disk. Need to image an internal HDD with OSX and see if this ameliorates the problem. Scellef 21:29, 11 September 2012 (UTC)
