and then select the new hardware from the list in the dialog box that appears.
Remember that it can take hours if not days before the first backup has
completed on a new backup device.
There are a number of advantages of having more than one backup destina-
tion, as follows:
• If you have a portable Mac, you can set up a Time Machine backup device
at home and one at work. Your Mac will seamlessly back up to whichever
one it's attached to without any need for you to select it. You could use
a removable disk drive at work, for example, and a Time Capsule at home.
• You can “rotate” disks by setting up two or more removable storage devices
for use within Time Machine and then attaching each daily (that is, disk
1 on Monday, disk 2 on Tuesday, and so on). This helps avoid wear on
any particular disk, reducing the risk of failure, but also lets you store
the currently out-of-sequence backup disks in a different physical location
to avoid all the backups being destroyed by a disaster such as a fire.

Share Reminders and Calendars
Within the Reminders app, you can share a reminder list with one or more
people, allowing them to create or delete entries in the list or check off tasks.
This can be useful if you're working on group projects or perhaps if you simply
want to share a shopping list with a family member.
You can also share a calendar within the Calendar app, which again can be
useful if you're working within a group. You could even create a special cal-
endar for a particular project and then share it with others. Others will be
able to view and create/modify/delete entries within the calendar, or you can
share it as read-only so people can only view the calendar's contents.
There are some caveats. The people to whom you want to share the reminder
list or calendar must be updated to the latest OS X Mountain Lion release,
must have an Apple ID (the login email address of which you'll need to specify),
and also must have iCloud activated within their Apple ID.
