Firmware is a type of software that is embedded in hardware devices, such as your MacBook. It provides the basic instructions that tell the device how to operate. Checking your MacBook’s firmware is important because it can help you identify and fix any potential issues.
There are a few different ways to check your MacBook’s firmware. One way is to use the System Information app. To do this, click on the Apple menu and select “About This Mac.” Then, click on the “System Report” button. In the System Report, expand the “Hardware” section and then select “Firmware.” This will show you the version of the firmware that is currently installed on your MacBook.
