EFIPW is a CLI utility for lab deployments and pen tests that can change the EFI firmware password on EFI (Intel) based Macs. The tool can also decode existing passwords for use in pen test audits.

Known to work on: Core Duo (1st gen) Macbook Pro 15" Core 2 Duo Macbook Pro 15"

Known to fail on: Macbook Air

In newer hardware models, Apple appears to not consult the nvram for information on EFI passwords or password policy. Since I don't have anything newer than a Macbook Pro (1st gen) available to me, I won't be able to reverse engineer this. If someone else decides to do so and it makes sense to include that code in efipw, send me an email and I'll incorporate it - with credit, of course :)
