Harden Mac security settings without breaking your workflow
Good hardening explains the tradeoff before it changes a setting. MacTidy organizes security into levels with visible costs.
The useful baseline
For most people, FileVault, automatic updates, a screen lock, firewall awareness, and careful sharing settings are higher value than exotic hardening. They reduce everyday risk with little friction.
Where hardening starts to cost you
Blocking incoming connections, disabling services, using outbound prompts, and enabling Lockdown Mode can break normal work. The right tool says that before the switch moves.
Why levels help
A named level turns scattered settings into an understandable destination. MacTidy still shows the individual controls and undo path, but the level gives the user a coherent choice.
Review-first workflow
- Check FileVault, firewall and update status.
- Review sharing and remote access services.
- Read the cost of stricter settings.
- Apply only the level that matches your risk.

FAQ
Common questions
What Mac security settings should I enable first?

Can MacTidy harden my Mac automatically?
It can apply some settings and guide you through others that macOS keeps under user control.
What is a Mac security level?
In MacTidy, a security level is a named bundle of settings with explanations, tradeoffs and undo guidance.
