Disk Utility User Guide

In the Disk Utility app on your Mac, choose View Show All Devices. In the sidebar, select the storage device you want to encrypt. Click the Erase button in the toolbar. Enter a name for the volume. Click the Scheme pop-up menu, then choose GUID Partition Map. Click the Format pop-up menu, then choose an encrypted file system format. Mar 26, 2013  Move the apps you want to protect to a password protected Disk Image. Then put an alias of them in your Applications folder. When an app is run it's going to ask you for the password of the Disk Image. Parental Controls work too.

When you format an internal or external storage device, you can encrypt and protect it with a password. If you encrypt an internal device, you must enter a password to access the device and its information. If you encrypt an external device, you must enter the password when you connect the device to your computer.

Important: If you encrypt an external storage device, you can’t connect it to an AirPort base station for Time Machine backups.

To encrypt and protect the device with a password using Disk Utility, you must erase the device first. If the device contains files you want to save, be sure to copy them to another storage device or volume.

2. In the Disk Utility app on your Mac, choose View > Show All Devices.

3. In the sidebar, select the storage device you want to encrypt.

4. Click the Erase button in the toolbar.

9. (Optional) If available, click Security Options, use the slider to choose how many times to write over the erased data, then click OK.

   Secure erase options are available only for some types of storage devices. If the Security Options button is not available, you can’t use Disk Utility to perform a secure erase on the storage device.

   Writing over the data three times meets the U.S. Department of Energy standard for securely erasing magnetic media. Writing over the data seven times meets the U.S. Department of Defense 5220-22-M standard.

10. Click Erase, then click Done.

You can encrypt your data without erasing it by turning on FileVault in the Security & Privacy pane of System Preferences (see Encrypt Mac data with FileVault).

You can also encrypt a disk and protect it with a password without erasing it. See Encrypt disks or memory cards to protect your Mac information.

Tax time is here and many of us will be sharing sensitive information from our financial institutions with our accountants. If there was ever a time to vigilant with securing your private data, this would the moment! Here's how you can create a compressed zip file with your sensitive data and password protect it on natively macOS.

Prep your files

Since we'll be using the terminal application that is native on macOS, you'll want to make the compression of your files as simple as possible to avoid long strings of commands. So if you have multiple files for compressing and protecting, you can organize them into a single folder using Finder.

1. Open Finder.

2. Option-click the Finder window and create a New Folder.

3. Rename the folder, preferably something without spaces as this will make terminal commands simpler for you.
4. Drag and drop your sensitive files into the new folder.

Once you have your files in the generated folder, you can now go on to the business of compressing and password protecting the files. Note that if you are e-mailing files, most e-mail providers have a limit on attachment sizes. Secondly, some companies disallow the reception of compressed files via e-mail due to people unknowingly opening malware and as such, your attachment may get stripped and the e-mail server. You'll need another method to transfer your files such as via Dropbox.

Since Finder doesn't have a native password protection option, we'll have to go deeper under the skin of macOS and straight up a terminal window.

1. Using Spotlight, type in terminal.
2. Change your directory to the location of your folder. For example, in my instance that would be to type cd /Volumes/dataMAC and hit enter.
3. Type in ls to make certain you see your folder.
4. Now type in the command that will simultaneously compress and password protect the files in the form of zip -er FILENAME.zip FILESorFOLDERStoCOMPRESS.
5. In my example that would be zip -er Mytaxes.zip ForTaxes/.
6. Hit return/enter.

7. Next, you'll be prompted with a password prompt. Type in the password you want to use to protect the files. Enter the password twice.

8. You should now see your compressed and password protected zip file in Finder.
9. You can test the protection by double clicking the file.

10. Enter your password.

11. The file will be uncompressed into the same directory.

Final comments

This compression and password protection is agnostic to the desktop operating system so you can send it to Window users, Linux users and of course Mac users. Let us know what other ways you use compression and password protection of your files on macOS in the comments.
