If you’ve got sensitive files you can secure them inside an encrypted DMG. It’s far less drastic than using Fire Vault, and it only takes a minute to implement.
People new to computers often confuse file permissions with encryption. Permissions can easily be circumvented. Any user with admin rights on the computer can change the permissions on a file. More importantly, anyone can take the disk and connect it to a different machine and change the permissions.
I am looking for a piece of software that can mount a DMG file on Windows or encryption software that can mount the encrypted volume as a virtual drive on Windows or mac. Most of the software I have found so far does not mount but as a virtual drive but have an interface to add or remove files and folders from the DMG.

It’s far less drastic than using Fire Vault, and it only takes a minute to implement. People new to computers often confuse file permissions with encryption. Permissions can easily be circumvented. VeraCrypt is free open-source disk encryption software for Windows, Mac OS X and Linux. In case an attacker forces you to reveal the password, VeraCrypt provides plausible deniability. AES Crypt is an advanced file encryption utility that integrates with the Windows shell or runs from the Linux command prompt to provide a simple, yet powerful, tool for encrypting files using the Advanced Encryption Standard (AES). A Java library is also available for developers using Java to read and write AES formatted files. Thunderbird is a free email application that’s easy to set up and customize - and it’s loaded with great features!
Encrypted files are different. The only way to access an encrypted file is with the password. Permissions rely on the security of the operating system for protection. Encrypted files have self-contained security, which also makes them portable.
You might want to make a back up of your novel and store it with your web host. But how do you know the web host won’t snoop? Tuck your files into an encrypted DMG before uploading and you’re all set.
When you create a DMG you’re prompted to add the password to your keychain. Download free movies on pc. That would defeat the purpose of the DMG in most cases. Chances are you’re encrypting files that aren’t going to be on your computer anyway. If they are going to remain on your computer consider leaving the password off the keychain to greatly enhance the security.
You could encrypt your entire home folder with Fire Vault, but that seems like a big step for most people. If something goes wrong or you can’t come up with the password you’ll be locked out of your own data, along with everyone else. Murphy only encrpyts files that are truly sensitive. Locking everything down doesn’t make sense.
When you’re done working with your volume eject it, don’t just close the window. Once ejected the volume requires the password for access. When you want to store the file elsewhere just copy the DMG file, not the volume.
Most of the time you'll never have to worry about having to install a new operating system on your Mac - the one that's on there should work fine through thick and thin. But every once in a while you might want or need to - here are step by step instructions for making it happen.
Use Recovery Mode
Every Mac operating system since Lion (OS X 10.7) has included Recovery Mode, a special boot partition that enables you to recover from catastrophic failures and problems. This can be used to install a fresh copy of Mavericks on your hard drive, provided you have Internet access. To use Recovery Mode, follow these instructions:
- Shut down your Mac.
- Press the Power button (the button marked with a O with a 1 through it)
- Immediately press the command (cloverleaf) key and R together.
- Make sure you're connected to the internet through Wi-Fi. If you're not, choose a network from the Wi-Fi menu that appears at the top-right corner of the screen.
- Select Install Mac OS X, then click Continue.
- Wait.
It's worth noting that this installs a fresh copy of OS X on your Mac without affecting either your files or your user settings, so you should be good to go as soon as it reboots. All applications are maintained, as well. This system simply replaces the core files that enable OS X to operate.
I've had occasion to see systems that don't work with Recovery Mode, for some reason. For those computers, it's often possible to restore access to the Recovery Mode partition by resetting the System Management Controller (SMC). To reset the SMC on most Macs:
- Shut down the Mac. If it's a laptop, make sure it's connected to the power cord.
- Hold down the Control, Option, and Left Shift keys simultaneously, then press the Power button.
- Release the keys.
- Press the Power button again. The system should turn on and you can give Recovery Mode another try.
If that fails to work, you can always download a fresh copy of the Mavericks installer from the Mac App Store.

Download a fresh copy of Mavericks from the Mac App Store
- Open the Mac App Store application, either from your Dock or from the Applications folder.
- Click on the Purchases tab at the top of the window or press command and 4 on your keyboard. (I'll assume for the moment that you have already installed Mavericks once - if you haven't, you should see an installation option in your Updates folder, assuming you have Snow Leopard or later installed.)
- Find OS X Mavericks in the list of files, either scrolling through the list or using the Search field in the upper right hand corner of the window.
- Click the Download button.
- You may get a dialog box advising you that OS X 10.9 is already installed on this computer. It's safe to click the Continue button.
- Be prepared to wait a while. Even over a fast Internet connection, it'll take a little while to download, since it's more than 5 GB.
- Once it's downloaded, it'll launch automatically. Follow the directions to install OS X.
Hopefully this will help you get started if you need to install a fresh copy of Mavericks. Questions? Fire away in the comments.
