Firmware Update for Macintosh

Can I update the firmware on my hard drive if it is installed in a Mac?

Yes, however it must be an Intel-based Mac (i.e. MacPro and iMac - with Intel inside). There are other models of Macs that have Intel processors such as the MacBook and MacBook Pro notebooks as well as the Mac Mini, but these drives have notebook (2.5 inch) drives which are not affected.

I have a PowerMac.  Can I update the firmware on my hard drive?

Older Macs that are PowerPC-based (PowerMac G3, G4, G5 and iMac G3, G4, and G5) are incompatible with the FreeDOS operating system which is required to perform the update.
