I was looking for a way to password protect a folder on the Mac. I needed to be able to backup a large collection of files onto a USB hard drive and then send it securely through the mail for safe off-site storage. For some reason, this functionality is not integrated directly into Finder. Then, follow our step by step guide password protect or lock files in Mac OS X. In this way no one can delete, move or open your files in the Mac without your permission.
Requirement to Password Protect:
- Apple computer
- OS X Leopard
STEP 1. Select the file or folder in your Mac and right click on it and then select “Get Info”
STEP 2. Then select “Sharing & Permissions”.
STEP 3. Now see on the right lower corner and click on small lock icon.
STEP 4. Here it will be prompted to enter your password. Enter your desired password and click on “OK” button.
STEP 5. Here you can also select who can access this file or folder in your computer by following process:
- select ‘Write only (Drop Box)’
- click the lock again to prevent any further changes.
STEP 6. Now under the General area in the Get Info box check the “Locked” check box which is located.
Now if someone try to delete or open your file in Mac it will be prompted to enter system password to proceed. So your files are secure now.
