Activation Lock Issue on MacBook Air - Request for Assistance

Dear Apple Support Team,

I am writing regarding an Activation Lock issue on my MacBook Air. Here are the details of my situation:

1. Purchase Details:

• I recently purchased a used MacBook Air in Iran.
• The seller initially set up the device with their Apple ID before transferring it to me.

1. Current Problem:

• After receiving the device, I performed a factory reset using my personal Apple ID.
• Upon restarting, I encountered an Activation Lock message indicating the device is still linked to the previous owner's Apple ID through Find My.
• The system continues to request verification with the original account, despite my using my own Apple ID for the reset.

1. Device Information:

• Model: MacBook Air
• Serial Number: c02********p

1. Steps Taken to Resolve:

• Attempted to contact the original seller to remove the device from their iCloud account (unsuccessful)
• Performed a full reset through Recovery Mode (Command + R)
• Verified Find My iPhone on iCloud.com to confirm the device does appear in my account

Request for Assistance:

Could you please advise how to resolve this Activation Lock issue?

Thank you for your time and support.
