How it checks whether your Mac’s firmware and security protection are current, and screens for major security issues.
FileVault
Do you need to back it up when the problem is minor? Should you erase its internal storage? Anything else you need to do?
If you’re wondering how to store snippets of private info, sensitive files, or folders full of secrets, here’s how to use the right features in macOS.
As macOS doesn’t have a dashboard to warn you of dangerous security settings, it’s worth checking them. Here’s what to look for, and how to correct them.
What if you’ve forgotten your Mac’s password, or the secondhand Mac you bought expects you to enter one, or its owner has died?
Here’s an APFS (Encrypted) volume that isn’t encrypted, and an unencrypted volume with FileVault active. Something must be wrong.
T2 and Apple silicon Macs always encrypt the Data volume in internal storage. So why bother with enabling FileVault? And can you do that on external bootable disks?
Is the performance overhead of using APFS Encrypted volumes to store sensitive data a reason for not doing so?
Running a Mac as a server supports all the features of HFS+ and APFS, services such as Content Caching, and spares us from learning Linux. But does it work?
On T2 and M1 Macs, FileVault provides robust protection of the Data volume on internal storage without any performance penalty.
