Updating firmware on an imac

Then, if something goes wrong during a firmware update, you can restart your Mac from the Firmware Restoration CD and your Mac will replace the corrupt firmware with the known good version.

There are currently 6 different Firmware Restoration files that cover various Mac models.

(For the full rundown, read the team’s blog post, which contains a link to the full research report.) “There shouldn’t be any deviance ever,” says Rich Smith, Duo’s director of research and development.

“But there is and in some cases it is quite significant.” Since 2015, Apple has bundled firmware updates in with updates to its operating system—a move the researchers applaud for taking some of the onus off users for keeping their systems up to date.

(Apple supplies the firmware as a download; you supply the CD.)When Apple removed the CD/DVD drive from Mac models, they realized that an alternate method of recovering from a corrupt firmware installtion was needed.

Apple could have provided the firmware restore system on a bootable USB flash drive, but instead the firmware recovery process is rolled into the Recovery HD hidden partition that is now included with all new Macs.

Even better you can use the following tips to create your own Recovery HD on any volume, including a handy USB flash drive you can carry around with you​.

The inconsistencies raise questions about the quality assurance Apple has been applying to firmware updates. “From the data we could see what was happening, but not say why it was happening,” Smith tells The researchers are set to unveil their research at the annual Ekoparty computer security conference in Buenos Aires, Argentina on Friday, where they hope to raise people’s interest in firmware security.

The topic popped into the news earlier this year when the anti-secrecy website Wiki Leaks posted an alleged dump of CIA files called Vault 7 that detailed a trove of hacking tools, including one, “Sonic Screwdriver,” that allowed spies to subvert Mac firmware.
