Information
The macOS be configured to require at least one lowercase character and one uppercase character be used when a password is created.
This rule enforces password complexity by requiring users to set passwords that are less vulnerable to malicious users.
Note: The guidance for password-based authentication in NIST 800-53 (Rev 5) and NIST 800-63B state that complexity rules should be organizationally defined. The values defined are based on common complexity values, but an organization may define its own password complexity rules.
Note: The configuration profile generated must be installed from an MDM server.

Solution
Configure the macOS system to require at least one lowercase character and one uppercase character in password complexity by installing the "com.apple.mobiledevice.passwordpolicy" configuration profile.
