Back up or move your Contacts data

Contacts in macOS stores a lot of vital information that you don't want to lose. Here's how to manually back it up.

• Launch Contacts
• Go to the File menu, scroll down to Export, then choose "Contacts Archive..."
• Name the backup something meaningful and export the .abbu file to the desired location

The resulting .abbu file is easy to reimport by going to File > Import in Contacts. This file can be stored for back up purposes or used if you just want to easily copy Contacts data to a new Mac.

What about iCloud? If you use iCloud, Contacts will synchronize its address book automatically with the cloud. This means you do have a separate copy of all your contacts there, but changes you make locally are synchronized. If you lose contacts locally, the synchronized copy at iCloud may have dropped them as well. Note that you can restore iCloud contacts to a previous state, however:

• Open iCloud Settings at
• Follow the Restore Contacts link under Advanced
• Click Restore next to the most recent backup copy you suspect to contain the lost data

iCloud will create a new backup copy of the current state of your address book (which you can restore using the same process), then replace all contacts on all your devices and with the archived copy.


Pin an iCloud enabled note to your desktop

The Notes app in OS X lets you tear off notes and to float over the OS X desktop. You can think of this as the Stickies app on steroids, and not only does it look better, but you can share directly from the Note. Best of all, if you have iCloud set up with OS X and iOS the pinned note will automatically update when it's edited from an iPhone or iPad via the iOS Notes app.

Here's all you need to do to stick a Note on the Mac desktop:

• Launch Notes app in OS X and double-click the Note you want to tear off
• Position the floating note on the desktop and then close the primary Notes app window

Super simple to get the Note onto the desktop, but now for best part:

• Grab an iPad, iPod touch or iPhone and launch Notes app
• Locate and edit the same note, it will automatically sync and update on the OS X desktop
