18.6 .Mac Services

In January 2000, Apple CEO Steve Jobs explained to the Macworld Expo crowds that he and his team had had a mighty brainstorm: Apple controls both ends of the connection between a Mac and the Apple Web site As a result, Apple should be able to create some pretty clever Internet-based features as a reward to loyal Mac fans Later that same day, the Apple Web site offered a suite of free services called iTools

POWER USER'S CLINIC Internet Sharing as a Bridge

Ordinarily, only one Mac has Internet Sharing turned on: the one that's

connected directly to the Internet

But sometimes, you might want another Mac "downstream" to have it on, too That's when you want to bridge two networks

Consider the setup shown here: There are really two networks: one that uses

AirPort, and another con-nected to an Ethernet hub

If you play your cards right, all of these Macs can get online simultaneously,

using a single Internet connection

Set up the gateway Mac so that it's an AirPort base station, exactly as described

on these pages

Start setting up the bridge Mac the way you'd set up the other AirPort Macs—

with AirPort selected as the primary connection method, and "Using DHCP"

turned on in the Network panel

Then visit the bridge Mac's Sharing panel Turn on Internet Sharing here, too,

but this time select "To computers using: Built-in Ethernet."

The bridge Mac is now on both networks It uses the AirPort connection as a

bridge to the gateway Mac and the Internet—and its Ethernet connection to

share that happiness with the wired Macs in its own neighborhood

Then the technology bubble burst

These days, Mac subscriptions (as they're now called) cost $100 per year For a full description, see Figure 18-10

Figure 18-10 The Mac features appear as buttons on the Mac Web site For example, iCards are attractively designed electronic greeting cards that you can send by email Backup is a basic backup program that you can download from this site Webmail, HomePage, an antivirus program, and features that synchronize your iCal and iSync data with other computers are the other secondtier features The best

feature, however, is iDisk

18.6.1 Signing Up for Mac

Open System Preferences and click the Mac icon Click Learn More You now go

online,where your Web browser has opened up to the.Macsign-upscreen.Fill in your name and address, make up an account name and password, turn off the checkbox that invites you to get junk mail, and so on

The final step is to return to the Mac pane of System Preferences Fill in the account name and password you just composed, if necessary You're ready to use Mac

18.6.2 iDisk

The iDisk is an Internet-based hard-drive icon on your desktop, holding up to 10

gigabytes of files (Your Mac account comes with 10 gigabytes of storage In your

account settings at www.mac.com, you can decide how to divide up that storage between your iDisk and the other Mac stuff, like mail and your Web sites And, of course, you can pay more money for more storage.)

Anything you drag into the folders inside this iDisk icon gets copied to Apple's secure servers on the Internet Meanwhile, on your end, it appears to work just like a harddrive

In other words, iDisk can be a handy pseudo-hard drive When you're saving a document from within a program, you can save it directly onto your iDisk And because

this backup disk is offsite, if a fire or thief destroys your office and your backup disks, your iDisk is still safe

Furthermore,you can pull the iDisk onto any computer's screen—MacorWindows—at your office, at your home, at your friend's house, so you don't need to carry around a physical disk to transport important files

18.6.2.1 Pulling it onto your screen

Apple must really love the iDisk concept, because it has devised about 300 different ways

to pull the iDisk icon onto your screen (Figure 18-11):

• Choose Go iDisk My iDisk (or press Shift- -I)

• Click the iDisk icon in the Sidebar (ofa Finder window or a Save or Open dialog box)

• Choose Go Connect to Server At the bottom of the resulting dialog box, type http://idisk.mac.com/casey(substitute your actual account name for casey) Press Enter Type your Mac name and password, if necessary, and then click Connect (This is the quickest approach if you're using somebody else's Mac.)

Figure 18-11 Choose GoGo iDiskGo My iDisk (top) or click the iDisk icon in your Sidebar When the iDisk finally appears (bottom right), double-click it—and wait—to see its contents (bottom left) Note that you can't create your own folders on this special disk; you must drag your files directly into

one of the folders shown here

• Visitwww.mac.comand click the iDisk icon Type in your name and password, and then click Enter Finally, click Open Youri Disk (Clearly,this is a lot more work

than the one-click methods already described Use this technique when you're using a public machine far from home, for example.)

At this point, thei Disk behaves like an external hard drive You can drag files or folders from your hard drive into one of the folders that appear on the iDisk

Note: You can't create your own folders in the iDisk's main window You must put your

files and folders into one of the folders already on the iDisk, such as Documents or

Pictures If you try to drag an icon directly into the iDisk window, or onto the iDisk icon, you'll get an error message

Thereafter, you can retrieve or open whatever you copied to the iDisk Open one of the folders on it; you can now open, rename, trash, or copy (to your hard drive) whatever you find inside

18.6.2.2 Making the iDisk fast and synchronized

As you can imagine, copying files to and from a disk on the Internet is slower than

copying them between hard drives on the same Mac The iDisk has a reputation,

therefore, of being very slow

But the iDisk doesn't have to run at the speed of an anesthetized slug Behind the scenes, Mac OS X can keep a full, invisible copy of the iDisk's contents on your hard drive When you add something to the iDisk, therefore, it seems to appear there instantly—even when you're not online—because all you've done is copy something onto a secret stash of your own drive The Mac will begin the process of transmitting the copy to the online iDisk at the next opportunity In short, you can leave the iDisk's icon onscreen for as long

as you like, even when you're offline

Figure 18-12 To turn on iDisk syncing, open System Preferences, click Mac, click iDisk, and then turn on iDisk Syncing by clicking the Start button If you have a broadband connection, leave "Update: Automatically" selected If you opt for manual synchronization (on a dial-up connection, for example), you have to trigger your own syncs by clicking the button next to the iDisk's name in the Sidebar

To turn on this feature, see Figure 18-12

Tip: If you have more than one Mac in different locations (home and office, for

example), you can keep your key files synchronized among all of them by turning on this automatic iDisk syncing on all of the machines You've burned your last "Take Home" CD!

18.6.2.3 The Public folder

In general, whatever you put onto your iDisk is private and password-protected There's one exception, however: Whatever you put into the Public folder on any iDisk can be seen, opened, and copied by any other Mac member All they need is your member name—not your Mac password (although you can password-protect it, if you like) Think of the iDisk Public folder as the long-lost twin of the Public folder in your own Home folder

The Public folder is terrific for storing family photos where anyone who's interested can look at them It's also handy when you're collaborating; just post the latest drafts of your work in the Public folder for your co-workers to review

To view someone else's Public folder, use one of these techniques; suppose the person's .Mac name is SkiBunny23:

• From Mac OS X 10.3,10.4,or10.5 Choose Go iDisk Other User's Public Folder Type in the person's member name, and hit Return

• Mac OS X 10.1 or 10.2 Choose Go Connect to Server At the bottom of the dialog box, type http://idisk.mac.com/skibunny23/Public Click Connect or press Enter If a password is required, use public as the user name and, well, the

password as the password

Tip: Actually, there's a simpler way: Use iDisk Utility, described below

• From Mac OS 9 Choose Chooser, click Apple Share,click the Server IP Address button, type idisk.mac.com in the Server Address box, and then click Connect Type skibunny23; for the password, use public (unless the folder really is password protected, in which case you should type the password you were given) Then click Connect Select the iDisk, and then click OK

• From Windows See the box on the next page

After a minute or so, a new iDisk icon appears on your desktop, bearing that member's name Double-click it to view its contents You can copy these files to your hard drive, or double-click them to open them directly

18.6.2.4 iDisk options

If you open System Preferences, click the Mac icon, and click iDisk, you're offered a few interesting options, along with a graph that shows how full your iDisk is getting Here, you can also make these changes:

• Let people put stuff in your Public folder Ordinarily, other people can deposit stuff into your Public folder as well as copy things out If you'd rather set it up so that only you can drop things in there, click "Read only."

• Password-protect your Public folder Probably a good idea if you decide to make your Public folder available for deposits

Note: These functions are available to pre-Panther/Tiger people (and Windows people

too) if they visit www.mac.com, click ".Mac Downloads," sign in, and download the program called iDisk Utility (or iDisk Utility for Windows)

18.6.3 Email

Apple offers an email address to each Mac member

Probably anyone who can get to the Apple Web site already has an email account So why bother? The first advantage is the simple address: YourName@mac.com And

because Mac is a Mac-only service, the odds are good that you'll be able to claim the name you want No longer must you be known as bgates28514@earthlink.net (Cultdom hasits privileges.)

POWER USER'S CLINIC The iDisk from Windows

Once, you could get to your iDisk only from a Macintosh These days, you can bring your iDisk onto the screen of any computer, even one running Windows

or Linux

The procedure varies by operating system, but the general idea is the same:

You're going to create a new "hard drive" in your My Computer window, whose icon represents the iDisk

If you have Windows XP and plan to connect regularly, you can download the

free iDisk Utility for Windows, which makes pulling up someone's iDisk a

simple matter of a couple of clicks Visit www.mac.com and click Mac

Down-loads to find it

Otherwise, here are the steps for different Windows versions:

Windows Vista: Open your Web browser Go to www.mac.com and log in;

click iDisk in the left column A new browser window opens Type your Mac

name and password, and click Log In

Windows XP: Choose Tools Map Network Drive in any desktop window

Windows 2000: Choose Tools Map Network Drive Click "Web folder or

FTP site."

Windows 98: Open My Computer Double-click the Web Folders icon; double-click Add Web Folder

In the XP/2000/98 cases, you should now type in this address as the location to add: http://idisk.mac.com/casey (where casey is your Mac member name)

When you're asked for a name and password, type in your usual Mac name and password

After a minute or two, you'll find the icon for your iDisk in the My Computer

window, sitting there as though it's a hard drive attached to the PC In Windows

XP, for example, it's in the Network Drives category, called something like

"Frank23 on 'idisk.mac.com.'"

Second, Mac.com addresses are integrated into Mac OS X's Mail program, as you'll see

in the next chapter And finally, you can read your Mac email from any computer

anywhere in the world, via the www.mac.com Web site

18.6.4 HomePage

Creating a Web page (an HTML document) isn't difficult Using a program like

Dreamweaver, GoLive, Netscape Composer, Keynote, or even Microsoft Word, you can design the text and graphics for a simple Web page in a single afternoon

It's much more difficult, however, to figure out how to post that Web page—to hang it on the Internet where the world can see it To do that, you need special software, several passwords and codes, and a lot of help from your ISP

The Mac HomePage feature eliminates all that hassle All you have to do is drag your Web-page documents and graphics into the Sites folder on your iDisk Your Webpage is instantly available for viewing by everyone on the Internet

Tip: You can create as many Web pages as you want When you return to the HomePage

screen, a list of your existing Web pages appears (complete with Edit Page and Delete Page buttons)

If you already know how to design Web pages, great; put the HTML documents and graphics you've created into the Sites folder of your iDisk

Then tell your friends its Web address Suppose that the Web page you designed is called index.html, and that your Mac member name is SkiBunny In that case, your custom-designed Web address is http://homepage.mac.com/skibunny/index.html (although most people can leave off everything after your member name)

And if you have no experience designing Web pages, Mac OS X itself can help you:

• iPhoto and Image Capture can both turn photos from your digital camera into handsome art-gallery Web pages After they've done so, drag the resulting HTML documents and image folders into your iDisk's Sites folder Presto! You've got yourself a photo-gallery Web page

• Sign into www.mac.com If you click HomePage, you'll find a large gallery of canned Web site design templates that you can easily fill up and post in

cyberspace: photo albums, movie players, résumés, baby announcements, and so

on

When you finally click the Publish button at the top of the screen, new Web page

(HTML) documents appear in the Sites folder of your iDisk Also, your screen now

displays your page's URL (Web address), which you can email to anyone who'd be

interested Unfortunately, it's not particularly catchy; it's along the lines of

http://homepage.mac.com/YourMemberName/baby.html

Finally, your Web page is available for anyone on the Internet to see Corporations and professional Web designers may sniff at the simplicity of the result—but it takes them a lot longer than 10 minutes to do their thing

18.6.5 Backup

.Mac membership also includes access to a program called Backup, which can give you

an effortless, even automatic backup system for your most important files It's among the

easiest-to-use backup program sever written, butit doesn't give you as much peace of mind as Time Machine (Chapter 6), which backs up your entire computer

For details on Backup, see this chapter's free downloadable appendix It's on this book's

"Missing CD" page at www.missingmanuals.com

18.6.6 iSync

iSync is the little program that syncs your calendar and address book to your cellphone or Palm organizer Details are on Section 6.5
