how to factory reset my macbook pro 2017 if I don't remember my firmwire password???
Forgot firmwire password
Hello Makkar. Your question would be best addressed by contacting Apple Support. An online search for "forgot Mac firmware password" shows the Apple Support article "Set a firmware password on your Mac" among the top results, and which includes a section on what to do "If you forgot your firmware password".
According to that page, you will need to schedule an in-person service appointment with an Apple Store or Apple Authorized Service Provider for assistance.
