Locked my macbook from find my app and fogot password

Hello Meli1914,

Thank you for reaching out to Apple Support Communities, and we'll be happy to help in any way we can. We understand you're having issues with unlocking your Mac from the Find My app. To start, follow the section of this article titled "If you can't unlock your Mac": If your Mac is lost or stolen

We hope this helps.

Cheers!

With proof of ownership/purchase an authorized Apple service

provider and/or Apple store genius might be able to access it.

A telling bit from the article If your Mac is lost or stolen cites:

"After you locate your Mac, you can unlock it by entering the

passcode that you created when you locked it with Find My."

• If you can't remember that passcode, you have three options:
• Sign in to iCloud.com/find, then select your Mac from the Devices menu. Select Unlock and follow the steps to verify your identity.
• Unlock your Mac from your iPhone, iPad, iPod touch, or Apple Watch using your device passcode.
• Take your Mac to an Apple Authorized Service Provider along with your proof of purchase.

"You can look up your passcode for a limited time."

..My crystal suggests: you may travel in search of 'the Mystic' whose task it is to provide Authorized Service..
