Basic Attestation User Root CA Keychain Mac OS Bigsur (macbook pro nov 2020)

Hi everyone,


I'm currently looking at my keychain (login) and found a Intermediary Certificate. It's called Basic Attestation User Sub CA1 (not trusted)

Organisation: Apple Inc.

State/Provence: California


Normal name: Basic Attestation User Root CA

Organisation: Apple Inc.

State/Provence: California


it seems very weird to me that the MB shows that this certificate is not trusted, as it seems that it's from Apple. The Certificate is valid until march 2032. Does anyone know what this certificate means, what it does. It's the only certificate that's not trusted. Do i have to remove this?


Thanks in advance.

MacBook Pro 13″, macOS 11.0
