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?

    1. To get boot ROM version on ElCapitan follow below steps.

      1. Click on Apple icon on Desktop.
      2. Select "About this mac"
      3. On the Overview tab, Click on System Report.
      4. System Report opens in another application window.

      Here you can see the boot ROM or SMC version information.

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

    1. The above command perfectly works on OS X ElCapitan, Can you tell me what error you are getting when you ran above command ?

    2. Try executing the below command :

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