The best security on your Mac came free with it.
FileVault encrypts everything if your Mac is lost or stolen. The firewall keeps uninvited connections out. Gatekeeper checks every app you download. Automatic security responses patch attacks, often on the same day they’re found.
But some of these are off by default, some get switched off and forgotten, and nobody wants to dig through System Settings to check.
Mac Shield checks them all in a second,
with no admin password needed:
- FileVault disk encryption;
- the firewall, and stealth mode;
- Gatekeeper;
- System Integrity Protection;
- automatic security updates and malware definitions;
- password after sleep;
- automatic login and the guest account.
Anything that’s off comes with a plain explanation of what it protects you from, and a button that opens the exact setting. That’s all free.
Pro Where a setting can be changed safely by a script, Pro fixes it in one click, after you confirm.
For people with more at stake,
such as serious crypto holdings or a high profile, Mac Shield also suggests Apple’s Lockdown Mode, and explains the trade-offs honestly.
