How to find firmware or boot ROM version in Mac OS X

Firmware and boot ROM version of your mac can be found in two ways.

Way 1 :

1. From "Apple" menu , choose "About This Mac" menu item.
2. Click " More Info " to open "System Profiler" application.
3. Under Contents -> Select Hardware Tree item.

On the right side panel Under hardware overview section, we can see Boot ROM Version and SMC (Firmware) Version.









Way 2 :

Run the below command in terminal to get boot ROM version and SMC(firmware) version :

$ system_profiler SPHardwareDataType | grep -i "Version" | awk -F ':' '{print $1 $2}'

  1. Neither of these two methods worked for me. Way 1 does not show anything called "More Info", "System Profiler" or "Hardware Tree item". Equivalent of "System Report..." doesn't disclose this either. Way 2 states "Command not found".

    Do you have anything that works with El Capitan?
