I was given a 2 TB Time Capsule, Model A1409 (made from 2011 to 2013) by the ‘heirs’ of a gentleman who has passed away some eight years ago. How do I get into it, even to only make sure that it’s properly erased before it meets its maker or find a collector on eBay.
It shows up with the Airport Utility (on an older Mac running High Sierra) but there it asks for a password that nobody knows.
How can I reset it?
