Lock and close vaults before switching users. Keep credentials in a trusted password manager.
Clear supported recent items and the current macOS clipboard only in the account and applications you are authorized to manage.
Review screenshots, Downloads, file names, and visible document previews that can expose personal information.
Permissions granted to one app copy or account do not provide consent to inspect another user’s data.
For organization-owned Macs, follow required logging, retention, and monitoring policy.
