How to lock a folder on mac with password without disk utility?

Locking a folder on Mac typically involves using built-in features like FileVault encryption, setting folder permissions, or creating a password-protected disk image (DMG). While these methods enhance security, there are some potential dangers or pitfalls to be aware of:

• Incorrect permissions or encryption errors can make the folder or data inaccessible.
• If you forget the password or encryption key, you may permanently lose access to the contents.
• Modifying permissions or encryption settings improperly can sometimes cause system or application errors.
• For example, changing permissions on system folders might interfere with normal OS operation.
• Turning on FileVault encrypts your entire disk. If you forget your login password or recovery key, you could be locked out.
• Data recovery options are limited without the recovery key.
• Creating password-protected disk images (DMGs) or encrypted containers can sometimes lead to corruption if interrupted during creation or mounting.
• If you set a password or permissions that you cannot remember or reset, you might be unable to access vital files without advanced recovery tools.
• Locking a folder on Mac can usually be bypassed with specialized tools if someone is sufficiently motivated.
