Q: i forgot my passcode

Since you are posting this in the Bootcamp forum, which is software designed to enable the running of Windows on a Mac, you might need to better describe what passcode you are referring to. Once you do that, someone should be able to assist you quickly.

Please see If you forgot the passcode for your iPhone, iPad, or iPod touch, or your device is disabled - Apple Support .

If this is related to any devices not mentioned in the previous link, Macs use Firmware Passwords. Please see If you lost or forgot your firmware password - Apple Support .
