Best Application to Lock Folders on Mac

Everyone have secret and confidential files, some keep such files secrets in their mind and some people just store them on their Mac operating system. But how do you keep such private and confidential files away from prying eyes? What would you do if you use a shared or a family computer? What would you intend to do, if you need to share that folder with someone, but don’t want it to fall into wrong hands?

Don’t worry! If you have the above stated question, the answer is simple locking such important folder on your Mac computer will help. Fortunately, Apple operating system has provided a way to lock i.e. password protect folders, no matter what the situation is. Here’s how it’s done.

  • Open Disk Utility (Applications --> Utilities --> Disk Utility)
  • Then, click on File --> New --> Disk Image from Folder
  • Choose a folder that you would like to lock, after which click "Image"
  • Select "read / write" option if you want your folder to be editable or modification-able (if not, choose read only format), after which select "128-bit AES encryption"
  • Type in your desired password and make sure the checkbox for "Remember password in my keychain" is not ticked, else it would be of no use locking your folder

Locking your folder on Mac machine is as easy as that! A password protected .dmg file will be created. Larger folder takes longer time to get locked. Once the folder is locked, you can delete the original one. To access and unlock the folder again, just double-click on the .dmg file and type in your password. Always make sure to uncheck the box saying "Remember password in my keychain", which ensures the folder is always locked with password.


  • If you have multiple folders to lock, then instead of selecting "Disk Image from Folder" you can select "Blank Disk Image" and then set a size limit for how large the locked folders can be.
  • For enhanced security, uncheck "add password to keychain" box. Also, remember to eject the .dmg file as soon as you have locked your folder.
