MacBook Pro SATA update
Apple on Monday released an EFI firmware update for the MacBook Pro models launched earlier this month. The update brings back support for the 3Gbps SATA specification, although the company warns that it has not offered or qualified drives running at transfer rates higher than 1.5Gbps. Earlier reports indicated the new systems had switched from 3Gbps specifications down to a 1.5Gbps limit.
A separate EFI firmware update for iMacs addresses a stability issue for systems utilizing ATI Radeon HD 4850 graphics components.Both updates are available from the Apple Support page. The MacBook Pro download weighs 3.35MB, while the iMac firmware is contained in a 1.7MB package.
