I have this MacBook Pro 16in 2021 model in Space Gray for sale. It has M1 Pro 10-core CPU and 16-core GPU, 32GB Ram and 1TB SSD. It is covered under AppleCare for Enterprise Warranty till 10/26/2026. But I can not guarantee how long AppleCare will last. At least, Apple Standard warranty will be active till 10/26/2023. 

The only issue is that this MacBook is enrolled in an MDM service. I have bypassed the MDM and now there is no MDM profile installed on it and it is fully functional just like any other MacBook Pro 16in purchased from Apple Store directly. It is in open box condition with battery cycle 12. The listing includes the MacBook itself and a charger only. No box. But I will pack it very carefully. 

If you would like to factory reset this MacBook, you need to bypass it again. Please google for instructions to bypass MDM. The current MacOS on this MacBook is Monterey and the online MDM bypass instructions are currently for Monterey only. Thanks for looking.
