The iMac EFI Update will update the EFI firmware on your iMac computer. When your iMac restarts, a gray screen will appear with a status bar to indicate the progress of the update. It will take several minutes for the update to complete. Do not disturb or shut off the power on your iMac during this update.

Boot ROM or SMC Version Information: After iMac EFIupdate has successfully completed, your Boot ROM Version will be IM121.88Z.0047.B1D.1110171110

Note: Before proceeding with your driver installation we suggest you make sure you are installing the latest version available and for the appropriate model/revision and Operating System. We strongly suggest following 'readme' instructions for installing drivers when available. Often restarting your system will be necessary for the new driver to become active and start functioning properly.
