iCloud is how a Mac, iPad, iPhone and iPod touch work together.1 It keeps your mail, calendars, contacts, reminders, documents, notes and more up to date wherever you use them. So when you add, delete or change something on your Mac, it also happens automatically on your iPad, iPhone and iPod touch. And vice versa. You don’t have to do anything at all — iCloud is automatic. Just sign in once with your Apple ID and iCloud is set up in all the apps that use it. Suddenly, life’s easier to juggle.
Organise your life on your Mac. It’s all in a list. More than one, in fact. Make as many lists as you need and easily add to them. Set deadlines and you’ll get alerts as they approach. Set a location from your Mac, and your iPhone or iPad will remind you when you get there.2 Tick items off your lists as you go and keep track of what you’ve completed. iCloud keeps your reminders up to date on your Mac, iPad, iPhone and iPod touch, so you don't forget anything.
Notes is designed for whatever’s on your mind, wherever you happen to be. Think it up. Jot it down. Make it even more noteworthy with photos, images and attachments. You can add, delete and flip through your notes, or do a quick search. Use the Share button to send your notes with Mail or Messages. Pin important notes to your desktop so they’re easy to get to. And take them with you everywhere. Notes works with iCloud, so when you create or edit a note on your Mac, it automatically updates on your iPhone, iPad and iPod touch. And vice versa.
Messages with iMessage takes your conversations even further. Because now you can send messages to anyone on an iPhone, iPad or iPod touch running iOS 5 too. Messages appear on your Mac and any device you use, which means you can say hi from your Mac and keep chatting on your iPhone or iPad, no matter where you are. Send photos, videos, documents and contacts — even send messages to a group. You’ll see when your message has been delivered and when someone’s typing a reply. Turn on read receipts and they’ll see when you’ve read a message. And with end-to-end encryption, your messages stay safe and private.
Something new is always popping up somewhere on your Mac — an email, a message, a software update, a calendar alert. Notification Center makes it easy to stay on top of it all. Notifications always appear in the same spot on your desktop and disappear quickly so they don’t clutter up your screen. Whenever you want to see all your notifications in one place, just swipe to the left from the right edge of the trackpad. And there they are, in a simple, ordered list. So you’ll always know what’s up as soon as it comes up.
When your Mac goes to sleep, it still gets things done with Power Nap.3 It periodically updates Mail, Contacts, Calendar, Reminders, Notes, Photo Stream, Find My Mac and Documents in the Cloud. When your Mac is connected to a power source, it downloads software updates and makes backups with Time Machine. While all that updating is going on, the system sounds are silent and no lights or fans come on, so nothing disturbs you. And when your Mac wakes up, it’s ready to go.
