For information about you such as name and address that remains constant, you iPhone’s Safari app’s AutoFill feature automatically fills in common fields with your personal information with a single tap instead of requiring you to fill in those fields individually. Safari can also keep track of user names and passwords and credit card information.

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.

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.

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.

When putting together a presentation, there are a bazillion apps that can help you create cool content. The ten apps we list here let you sketch, make graphs, edit photos and video, and add special effects. For the most part, you create the content and then either save it as a PDF or import it directly into your presentation app (PowerPoint, Keynote, or whatever you use).

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.
