Why can't I disable iCloud keychain on my MacBook? Running macOS 10.12.6. I'd like to keep this machine connected to iCloud calendars but prevent it from having a copy of my keychain.



Update: Someone suggested I go into iCloud > account details and turn off allow approving with security code but these are the only tabs that I see. Within the devices tab, I can only remove devices from my account. There is no other option.
If Calendars is the only thing that this Mac needs from your AppleID, then one solution would be to give this Mac a separate AppleID, and share the Calendar.
