    MacBook Air Portable Genius - Paul McFedries

    Chapter 1: How Do I Connect Devices?

    9781118370209-co0101.tif

    You love MacBook Air because it doesn’t require you to be a genius to accomplish basic, everyday tasks. Got a new mouse? Just plug it into one of the USB ports and it’s ready to use within seconds. Nice! Unfortunately, some devices are more ornery and require a bit of extra effort on your part to get them connected and configured. In this chapter, I take you through connecting a few such devices, including Thunderbolt devices, an external display, another Mac, a printer, and imaging devices such as digital cameras and scanners.

    Connecting Thunderbolt Devices

    Connecting external devices to a computer has always suffered from two problems: speed (or lack thereof) and inconvenience. The speed issue is an ancient one, and interface designers have been slowly increasing the pace at which various technologies transfer data. For example, USB has gone from a pokey transfer rate of 12 megabits per second (Mbps) in version 1.0, to 480 Mbps in 2.0, and 5 gigabits per second (Gbps) in 3.0. Similarly, FireWire has gone from 400 Mbps in FireWire 400 to 800 Mbps in FireWire 800.

    The convenience issue is more complex:

    bullet.tif Compatibility. Although newer interface standards are usually backward-compatible with earlier standards, devices designed for the old standard often require an adapter. For example, adding a FireWire 400 device to a FireWire 800 port requires a FireWire 800-to-400 adapter cable.

    bullet.tif Connections. Interface connections can be maddeningly inconsistent. USB is the main villain here, with legions of different device-side connectors, including Micro, Mini, Standard-A, Standard-B, and so on.

    bullet.tif Driver support. Device driver support can be shaky, particularly with newer technologies. For example, USB 3.0 devices often lack the drivers required to take full advantage of the interface’s new features.

    bullet.tif Port availability. This can be problematic, depending on the computer. This is particularly true on the MacBook Air, which includes just two USB ports and no FireWire ports. On many computers, particularly notebooks, if you need to connect multiple external devices, you often need to use a hub.

    Compare all this with the current state of the art in internal device connections: PCI Express. This interface is widely used (all Macs, including MacBook Air, use PCI Express internally), it’s blazingly fast (up to 16 Gbps), and device drivers are easy to come by.

    The performance and convenience gap between internal and external connections has never been more of a concern because nowadays we’re not just connecting keyboards and mice: We’re adding peripherals such as external hard drives, RAID arrays, Ethernet cards, and video capture devices that scream for as much throughput as you can give them. What the world needs is an external device interface that’s both super fast and super convenient.

    Welcome, then, to the world of Thunderbolt. Developed by both Intel and Apple, Thunderbolt effectively combines both PCI Express and Apple’s Mini DisplayPort display technology (which I discuss in more detail in the next section):

    bullet.tif Speed. Thunderbolt offers two data channels, each of which supports 10 Gbps throughput.

    bullet.tif Flexibility. Thunderbolt supports not only data transfer components, such as hard drives and video capture devices, but also high-resolution displays.

    bullet.tif Compatibility. A Thunderbolt port is the same size and shape as a Mini DisplayPort (see Figure 1.1), so devices designed for Mini DisplayPort, such as the Apple LED Cinema Display, can plug right in. Similarly, adapters designed to work with Mini DisplayPort, such as adapters for DVI and VGA displays, still work with Thunderbolt ports. Unfortunately, devices designed for Thunderbolt do not work with Mini DisplayPort connectors.

    9781118370209-fg0101.eps

    1.1 The fourth- and fifth-generation MacBook Airs come with a Thunderbolt port for connections to external displays and other devices.

    bullet.tif Connections. Thunderbolt supports daisy-chaining, which means a single port can support multiple devices, up to six at a time. This works because many Thunderbolt-compatible devices come with multiple Thunderbolt ports. For example, take a look at the rear of the Promise Pegasus R4 RAID storage unit, shown in Figure 1.2. As you can see, it includes two Thunderbolt ports. This means you can run a Thunderbolt cable from your Mac to the device, and then run a second cable from the other Thunderbolt port to another device.

    9781118370209-fg0102.eps

    1.2 Many Thunderbolt devices come with two ports, so you can daisy-chain multiple Thunderbolt devices to your MacBook Air without requiring a hub.

    note.eps

    The latest 27-inch iMacs also come with two Thunderbolt ports.

    The fourth-generation (2011) and fifth-generation (2012) MacBook Airs come with a single Thunderbolt port (shown earlier in Figure 1.1), so you can use it to connect Thunderbolt devices.

    Connecting an External Display

    If you have an extra external display — a monitor, television set, or projector — just lying around, you can connect it to MacBook Air for various scenarios:

    bullet.tif As an alternative display. You can use the external display instead of MacBook Air’s built-in monitor.

    bullet.tif As a desktop extension. You can use the external display to extend the MacBook Air desktop.

    Fortunately, both of these connection types are plug-and-play (meaning once you plug in and turn on the external display, MacBook Air recognizes the new device right away). That’s the good news. The bad news is that although using an external monitor is plug-and-play, the plug part isn’t as straightforward as you might like because there are many ways to connect a MacBook Air to a display. The next few sections provide you with the details you need to make things happen.

    Understanding external display connections

    To connect MacBook Air and an external display, you need to know the various ways these connections can occur. The next few sections provide you with the details.

    Thunderbolt connections

    As I mentioned earlier, the fourth- and fifth-generation MacBook Airs come with a Thunderbolt port. Thunderbolt supports both data transfer devices (for example, hard drives and RAID arrays) and high-resolution displays. So if you have a Thunderbolt-compatible display, such as the Apple Thunderbolt Display, you can use a Thunderbolt cable to connect the display to MacBook Air.

    If you have a device that uses a different connector type — such as DVI or VGA — you can still use MacBook Air’s Thunderbolt port, but you’ll need an adapter. Fortunately, existing Mini DisplayPort adapters (which I talk about a bit later) work just fine with the Thunderbolt port, so you shouldn’t have any trouble connecting other displays to MacBook Air.

    Mini DisplayPort connections

    On the third-generation (2010) edition of the MacBook Air, the display connection was the Mini DisplayPort, which is the same size and shape as the Thunderbolt port shown earlier in Figure 1.1, although it doesn’t support Thunderbolt devices. (The original MacBook Air used a Micro-DVI port.)

    You can use the Mini DisplayPort to connect MacBook Air to external displays that use three connector types: DVI (digital video interface), VGA (video graphics array), and video.

    To connect MacBook Air’s Mini DisplayPort to an external display, you need at least a Mini DisplayPort cable. If your display supports Mini DisplayPort signals, your work is done. Otherwise, you need to purchase an adapter that converts the Mini DisplayPort signal to video output compatible with your display (as I explain in the next three sections).

    DVI connections

    The standard video connection type on most LCD monitors and on some televisions and projectors is DVI. That sounds simple enough, but, unfortunately, external displays such as LCD monitors and televisions can use different DVI connectors. There are actually three types:

    bullet.tif DVI-A. This connector works only with analog signals (see Figure 1.3).

    9781118370209-fg0103.eps

    1.3 A DVI-A connector.

    bullet.tif DVI-D. This connector works only with digital signals. It comes in single-link and dual-link versions (see Figure 1.4).

    9781118370209-fg0104.eps

    1.4 DVI-D single-link (left) and dual-link (right) connectors.

    genius.eps

    What’s the difference between single-link and dual-link? DVI uses a transmitter to send information along the cable. A single-link cable uses one transmitter, whereas a dual-link cable uses two transmitters. This means that dual-link connections are faster and offer better signal quality.

    bullet.tif DVI-I. This connector works with both analog and digital signals. It comes in single-link and dual-link versions (see Figure 1.5).

    9781118370209-fg0105.eps

    1.5 DVI-I single-link (left) and dual-link (right) connectors.

    As you can see, each type of DVI connector uses a slightly different pin arrangement. When you’re matching your external display, DVI cable, and DVI adapter (described next), you need to make sure that they all use the same type of DVI connector.

    note.eps

    In high-tech cable and port connections jargon, a connector with pins is described as male and a connector with holes is described as female. Both of the Mini DisplayPort to DVI adapters use a female DVI connector, which means you can’t plug either one directly into an external display’s DVI port, because it is also female. In other words, you need to run a DVI cable — which is male on both ends — between the adapter and your external display.

    To connect MacBook Air’s Mini DisplayPort to a DVI port on an external display, you have two choices depending on the type of DVI required by the display:

    bullet.tif DVI-D single-link. You need to get the Apple Mini DisplayPort to DVI Adapter.

    bullet.tif DVI-D dual-link. You need to get the Apple Mini DisplayPort to Dual-Link DVI Adapter, shown in Figure 1.6.

    If the external display uses a DVI-I port, it probably means you have a DVI-I cable, and that cable won’t fit either of the adapters’ DVI-D connectors. In this case, the adapter on its own won’t cut it. To solve the problem, you either need to buy a DVD-D cable or you need to hunt down a DVI-D to DVI-I adapter so you can use your DVI-I cable.

    9781118370209-fg0106.eps

    1.6 Use the Apple Mini DisplayPort to Dual-Link DVI Adapter to connect your Mac’s Mini DisplayPort to an external display’s dual-link DVI port.

    note.eps

    A dual-link DVI connector plugs into (and works with) a single-link DVI port. Unfortunately, the reverse isn’t true; that is, you can’t plug a single-link DVI connector into a dual-link DVI port. Note, too, that a DVI-D connector can plug into a DVI-I port, but a DVI-I connector won’t fit into a DVI-D port.

    VGA connections

    All CRT monitors and many LCD monitors and projectors come with a VGA connector, shown in Figure 1.7.

    To connect MacBook Air to an external display that offers only a VGA connector, use the Mini DisplayPort to VGA adapter, shown in Figure 1.8.

    9781118370209-fg0107.eps

    1.7 VGA connectors are standard on CRT and common on LCD monitors.

    9781118370209-fg0108.eps

    1.8 Use the Mini DisplayPort to VGA adapter to connect the MacBook Air Mini DisplayPort port to an external display’s VGA port.

    Video connections

    If your external display is an older television or projector (or even a VCR), it likely has either a Composite (yellow RCA) connector or an S-Video connector; both are shown in Figure 1.9. To connect MacBook Air to an external display that only offers either Composite or S-Video connectors, use the Mini DisplayPort to VGA adapter, and then get a second adapter to convert the VGA signal to the output you require (VGA-to-video adapters are offered by many third-party manufacturers).

    9781118370209-fg0109.eps

    1.9 Composite (left) and S-Video (right) connectors are common on televisions, projectors, and VCRs.

    If your external display is a high-def TV, it most likely comes with an HDMI (High-Definition Multimedia Interface) connector. To connect MacBook Air to an external display that only offers an HDMI connector, you need to get a Mini DisplayPort-to-HDMI adapter. As of this writing, Apple doesn’t offer such an adapter, but some third-party companies do, such as the adapter made by Moshi (http://store.moshi monde.com), shown in Figure 1.10 (which is also available through the Apple Store).

    9781118370209-fg0110.eps

    1.10 Use the Mini DisplayPort-to-HDMI adapter to connect your MacBook Air to an external display’s HDMI port.

    Setting the external display mode

    The hard part about using an external display is getting the correct cables and adapters and ensuring they fit into the appropriate connectors, particularly on the display. However, once that is set, the rest is a breeze. As soon as you connect the external display and turn it on, MacBook Air recognizes it and starts using it. That’s more like it!

    How you use the external display depends on what you want to do with it. MacBook Air gives you two choices:

    bullet.tif Video mirroring. This external display mode means that the same image that appears on the MacBook Air’s main or built-in display also appears on the external display. This is useful if you want to use a larger monitor to work with MacBook Air or if you want to show MacBook Air’s desktop on a projector so that other people can see it.

    bullet.tif Extended desktop mode. This mode means that MacBook Air’s desktop is extended onto the external display. This is useful if you need more screen real estate to display your programs. For example, you can have your main application open on one display and an application that you’re monitoring — such as Mail, iChat, or Safari — on the other display.

    To switch between these external display modes, follow these steps:

    1. Click System Preferences in the Dock. The System Preferences window appears.

    2. Click the Displays icon. The display preferences appear, and you see one set of preferences for each screen.

    genius.eps

    After you connect your external display, you should calibrate the display so that the colors of images appear correctly. To calibrate a display, open its display preferences, click the Color tab, and then click Calibrate. This launches the Apple Display Calibrator Assistant, which takes you step by step through the calibration process.

    3. Click the Arrangement tab to select the external display mode.

    • To turn on video mirroring, select the Mirror Displays check box, shown in Figure 1.11.

    • To turn on extended desktop mode, deselect the Mirror Displays check box.

    4. If you turned on extended desktop mode, use the objects in the Arrangement tab to configure the screen layout (see Figure 1.11). To set the relative screen positions, click and drag the screen icons to the positions you prefer. To set the location of the menu bar, click and drag the white strip to the screen you prefer.

    9781118370209-fg0111.eps

    1.11 Use the objects in the Arrangement tab to configure the screen layout in extended desktop mode.

    Connecting MacBook Air to Another Mac

    If you have another Mac kicking around, it’s natural to want to share things between that Mac and your MacBook Air: documents, Safari bookmarks, iTunes libraries, downloads, and more. The standard way of sharing data between computers is to create a network. However, that requires a central connection point for the computers, usually a router. If you don’t have such networking hardware handy (for example, you’re in a hotel room or on a plane), you might think that sharing is off the table, but that’s not true. There are actually several ways that you can connect two Macs directly: with a Thunderbolt cable, with a network (or crossover) cable, or by creating an ad hoc wireless network. The next two sections provide the Thunderbolt and network cable details; see Chapter 2 to learn about creating an ad hoc wireless network.

    Connecting to another Mac using a Thunderbolt cable

    If you have a fourth- or fifth-generation MacBook Air and you just happen to have a Thunderbolt cable lying around, that’s great because you can use it to connect MacBook Air and another Mac via their Thunderbolt ports and share files between them. I’m assuming here, of course, that the other Mac also comes with a Thunderbolt port (as almost all recent Macs do; the one exception is the Mac Pro).

    Besides connecting the two Macs using the Thunderbolt cable, you also have to make sure that your Macs are configured to share files. Follow these steps:

    1. Click System Preferences in the Dock.

    2. Click the Sharing icon. The Sharing preferences appear.

    3. Turn on file sharing.

    OS X Mountain Lion, Lion, Leopard, or Snow Leopard. Select the File Sharing check box.

    Earlier versions of OS X. Select the Personal File Sharing check box.

    4. If you feel like it, you can also use the Computer Name text box to edit the name of your Mac, which is the name that will appear in the Network window of the other Mac.

    To see the other Mac, open Finder and then choose Go →Network (or press Shift+ maccmd +K). Double-click the Mac’s icon, click Connect As (in Lion or Leopard) or Connect (in earlier versions), and then type a name and password to connect to the other computer.

    Connecting to another Mac using a network cable

    The other way to connect MacBook Air to another Mac directly is to string a network cable between them. A network cable is also called a twisted-pair cable (because it consists of four pairs of twisted copper wires that together form a circuit that can transmit data), and it comes with an RJ-45 jack on each end.

    Your MacBook Air doesn’t come with an Ethernet port, of course, so you’ll need to connect an Ethernet adapter to one of MacBook Air’s USB ports. A good example is Apple’s USB Ethernet adapter, shown in Figure 1.12. One of the network cable’s RJ-45 jacks plugs into the Ethernet adapter, and the other connects to the corresponding Ethernet port on the other Mac.

    The connection is basically the same as with a Thunderbolt cable, so I’ll just give you the barebones steps here (see the previous section to flesh out the details):

    1. Connect the network cable to both Macs.

    2. Turn on file sharing on both Macs.

    3. Use Finder’s Network window (choose Go Network) to connect to the other Mac.

    9781118370209-fg0112.eps

    1.12 You can connect MacBook Air to another Mac via a network cable using Apple’s USB Ethernet adapter.

    Connecting and Sharing a Printer

    Nine times out of ten — it’s probably more like 99 times out of 100 — connecting a printer to MacBook Air is a no-brainer: You plug it in to the USB port, turn it on, and presto! MacBook Air and your printer have already become fast friends and you can start printing right away. How can you be sure? You can tell in a couple of ways:

    bullet.tif In any application that supports printing, choose File Print. In the dialog that appears, you should see your printer’s name in the Printer list.

    note.eps

    You can also display the list of connected printers from any application that supports printing. Choose File →Printer, open the Printers list, and then select Add Printer.

    bullet.tif Click System Preferences in the Dock, and then click Print & Scan. In the Print & Scan preferences that appear, you should see your printer’s name in the Printers list, as shown in Figure 1.13.

    genius.eps

    Surprisingly, Windows doesn’t have a monopoly on annoying behavior. One of the senseless things that OS X does is set the default printer to whatever printer you used or added most recently. To fix this, choose System Preferences →Print & Scan. Then, in the Default Printer list, choose the printer you want to use as the default.

    9781118370209-fg0113.eps

    1.13 If MacBook Air recognizes your printer, it appears in the Printers list in the Print & Scan preferences.

    Connecting a printer manually

    What happens on those rare occasions when MacBook Air doesn’t recognize your printer? In that case, you need to do a bit more legwork and install the printer manually. Here’s how it’s done:

    1. Connect and turn on the printer if you haven’t done so already.

    2. Click System Preferences in the Dock, click Print & Scan, and then click the Add button (+). MacBook Air displays the list of connected printers.

    3. Choose your printer.

    • In OS X Mountain Lion or Lion, if your printer appears in the list of nearby printers, click it and then skip the rest of these steps; otherwise, click Add Other Printer or Scanner.

    • If your printer appears in the list of available printers, simply choose it from the list.

    • If you don’t see your printer in the list, install the printer driver by hand as follows:

    1. Insert the disc that came with your printer. Note that you’ll need to connect an external optical drive to your MacBook Air, or use a remote optical drive, as described in Chapter 2.

    2. Choose Other in the Print Using list.

    3. Open the printer disc (or the folder where you downloaded the printer driver), choose the printer driver, and then click Open.

    4. In the Print Using list, choose Select a driver to use and then choose your printer if it is in the list that appears.

    5. Click Add. Your printer is now connected.

    note.eps

    If you don’t have an external optical drive or a printer disc, or if the disc doesn’t contain MacBook Air drivers, visit the printer manufacturer’s website and download the drivers you need. If
