As is the case in the previous years, I have written an e-book about OS X 10.11 El Capitan.

It is available now on Apple's iBooks Store in both iBooks format as well as ePub format. You can also purchase it from Amazon if you prefer using the Kindle app or e-reader. The cost for the e-book is $3.99.

OS X 10.11 El Capitan for Users, Administrators and Developers covers many of the new features within the operating system. For users, we cover the new Split View, the changes to the cursor, the new San Francisco Font, changes to Spotlight, upgraded Notes, improvements to Apple Maps, and the new features of Safari.

For administrators we cover the big changes to application assignment and other changes to Profile Manager, the overall look, some file sharing changes, the improved softwareupdate command, the implications of security changes, and built-in application versions.

For developers we look at the new Apple Developer account, Xcode 7, the new frameworks like Metal, GameplayKit, and Network Extension. We also look at the changes developers need to make for security, Swift 2, changes to Objective-C and CloudKitJS.

Millions of individuals have now received their new iPhone 6s and iPhone 6s Plus devices. There are some that may have, like myself, enabled Two-Factor authentication with Apple. If they are upgrading their iOS device, it would be a good time to add that new device as a trusted device. I thought I would provide a step-by-step tutorial on how to accomplish this.

• Enable Find My iPhone on your device.
• Open Safari
• Go to https://appleid.apple.com
• Click on "Manage Your Apple ID".

• Enter in your Apple ID and Password.
• Click on "Sign In".
• Select a device to authenticate your login.

• Click on Next.
• Wait for one-time code to be sent.
• Enter in the digits from the one-time passcode.

• Click on "Verify".
• Click on "Passwords and Security" on the left.

• Under "Manage your trusted devices", click on "Add or Remove Trusted Devices".
• Locate the Device that needs to be added.

• Click on "Verify" next to the device that you want to add.
• Wait for the one-time code to be sent.
• Enter in the verification code that was sent to your new device.

• Click Verify.

It is that simple to add a device to your trusted devices for two-factor authentication for Apple.
