hello, I've started using a mac mini that was shelved for some time. Out of the blue, I am asked for a six didgit system lock PIN code. Never seen this before, do some quick research, and find lots of similar solutions:

Go to www.iCloud.com/find1. .

2. Sign in with your Apple ID and password.

3. At the top, click All Devices.

My device does not show up on the list.

why am i getting this message and what do I do now?

thank you

mac mini.... bought new or used?

worse case scenario—schedule an in-person service appointment with an Apple Store or Apple Authorized Service Provider ( Find Locations )

Bring your Mac to the appointment, and bring your original receipt or invoice as proof of purchase.
