Most firmware updates are automatically installed when you update or upgrade OS X. Some firmware updates are also available as downloads you can install manually. If your Mac needs a firmware update and it isn't installed automatically, check to see if a manual updater is listed below.
If you don't see a firmware version listed in this article, it means that either a firmware update is only available as an automatic update, or no firmware update is needed.
Use these steps to check your Mac's EFI Boot ROM and SMC firmware versions.
If the firmware version you see in System Information is newer than what's listed for your Mac, you don't need to apply the updates listed for that model. If you try to use a manual updater that's not designed for your Mac, or if it's not needed, the installer alerts you and the software isn't installed.
