Time Capsule backup
My new computer died last week but it was backing up on my wifi Time Capsule using Time machine. When I view my Time Capsule I see the name of the computer that died and last backup but I when I hold down option and click I cannot see any package contents. Its shows there is 350GB so there is stuff there but can't see to access it. Also when I use migration assistant is does not see it. Any ideas?
MacBook Pro (13-inch, Late 2016, 4 TBT3), macOS Sierra (10.12.6)
