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.
APFS
How to protect collections of files using different encryption passwords, and making most efficient use of storage space.
Disk errors threaten your data: how to detect them, how to use First Aid in Disk Utility, how to use fsck, and what to do with the disk afterward.
