When you first turn on your Mac (or install an upgrade to the operating system), a series of questions and prompts appear, including a prompt to sign in to your Apple ID account or create a new Apple ID.An Apple ID identifies you and your devices in all things Apple that you do: registering new products, purchasing media and apps from the iTunes Store, the Book Store, and the App Store, as well as signing in to your iCloud account.

iCloud remotely stores and syncs data that you access from various devices — your Mac and other Apple devices, such as iPhones, iPads, and iPods, and PCs running Windows. Sign in to the same iCloud account on different devices, and the data for activated apps syncs; that is, you find the same data on all your devices, and when you make a change on one device, it shows up on the others.

Safari and iCloud have terrific built-in features that help you remember user names and passwords and credit card information. And Safari has security and privacy features to keep that personal information to yourself — or to your Mac. Here, we tell you how to use AutoFill so Safari remembers passwords for you, and then we explain how to keep your information safe.

Many people consider passwords to be less than ideal for security. To begin with, you have to remember them. The only sure way to make sure you don’t forget or lose your password is to write it down and keep that piece of paper (or whatever you wrote on) safe.There’s a better way if you have a current MacBook Pro or MacBook Air that supports Touch ID.

Sooner or later in your professional life, you’ll have to give a really important presentation. By focusing on several distinct and unique aspects of creating a presentation (topic selection, audience analysis, visual design, and delivery technology and techniques), you can develop the skills to give innovative, stimulating presentations with consistently positive results.

The iPhone's Contacts allows you to include all sorts of details about any person in your phone book, from their relationship to you, job title, or social media addresses. Here are some details of the fields you can use in Contacts. Add Related Name This is one of our favorite features of Contacts. For example, before this feature was added, Barbara would create a custom field for the phone number of a colleague's secretary and add him to the contact info of the colleague.

Folders on your iPhone give you the option of putting like-minded apps together in one place so you can find them quickly and easily. Think of folders as a way to organize your iPhone Home screen. You can organize directly on iPhone or use iTunes. How to consolidate apps into folders To add a folder, press and hold your finger on an app on the iPhone Home screen until they start a-wigglin' and a-jigglin'.

Your iPhone, especially if you have a version with 32 or 64 gigabytes of memory, is a portable video warehouse, and iPhone 5 and later versions have a larger screen and Retina display that make watching a pleasure. Nonetheless, watching a documentary about the Himalayas on your iPhone really can't match the thrill of sweeping views that a large-screen monitor or television offers.
