“How can I password protect files on Mac? I am looking for a way to basically lock files in my Mac via password. I don't want these files to be viewed easily but I also don't want to burn them into my hard drive or anything like that. Is there any way to password protect these kind of files from someone who might hop on my Mac and these files popping up unexpectedly?” From an anonymous Mac user.
Computers have become the place where you store pictures, documents, videos,favorite music and everything else in the same place. But everybody who is able to access to your computer can open your important files easily. If you want to keep movies, pictures and other files under a safe lock, setting a password to protect them is very necessary. This article will show your how to password protect files on Mac using three certain ways.
Disk Utility, which is primarily intended as a disk repair and imaging utility, can also be used to create a disk image that contains a folder’s worth of encryptedfiles. It is a default built-in feature of the macOS allows you to create password to password protected folder. Using Disk Utility to password protect files will cost you nothing but it is not easy to operate, but don’t worry, below will show you detailed steps on using Disk Utility to password protect files.
1. Open Disk Utility by going to the Applications Folder and then through Utilities.
2. Once inside, go under “File” and select “New”.Here, choose “Disk Image From Folder” and browse for the preferred folder which you want to be encrypted.
3. After choosing it, click “Image” and a new menu will pop-up with three possible options: to read/write the image, only to read it or to encode it. If you choose only “read”, you will not be able to add other files into that image.
4. Choose “Save”and type your password. It is very important to let unchecked the “Remember password in my keychain” option to be sure that other people that use that computer will not be able to open it.
Pros and Cons: You personal or important files such as videos, photos, folders can be encrypted with a 256-bit AES encryption using Disk Utility. This algorithm is one of the best solutions used nowadays for protection because it offers maximum security. And your disk image will take up as much storage as the sum of the files within it. So, even though you’ve created a 2.5GB image, if you’ve only flung a single 300MB file into it, that’s the size it will be. But this way is not very easy touse.
The print-to-PDF feature in macOS is convenient for quickly preserving a document’s layout in the PDF format, so it can be viewed on most computers and tablets.If you would like to send someone a formatted document that contains sensitive information or if you are uploading or syncing the files to third-party cloud storage services, you may want to encrypt the document with a password. This will work for any file-type that gives you the option to “print” a file to PDF.
1. Open any file you want to convert to a password protected PDF.
2. Go to File > Print. When you get the Print window, look for a little button marked “PDF”. Click it, and choose “Save as PDF”.
3. Before you save the file, be sure to click the “Security Options”button.
4. Check the box next to “Require password to open document”and enter a password, enter it again to verify, then choose “OK”.
Pros and Cons: It is easier than using Disk Utility. But “Print to PDF” offers one algorithm, which is 128-bit RC4. It only supports files which can be converted to PDF, that’s the restriction of this way.

I used the disk utility method, once I open the file with my password, it creates a disk image on my Mac that I can open without my password. So I have to delete that disk every time I access it.
Don't DELETE the disk image, do an EJECT ONLY to close the disk image. Your files go back to being encrypted with your password protection.
very useful, with the three methods, i can lock any files i want including videos, photos, document files, compressed files on Mac. I also want to buy AppCrypt to lock my apps on Mac
