1. What is a Mini DisplayPort?

A Mini DisplayPort delivers a pure digital connection to external displays. It gives you plug-and-play performance with the Apple LED Cinema Display and works with single-link DVI, dual-link DVI, and VGA displays with the appropriate adapters.

2. Does my computer have a Mini DisplayPort?

The Mini DisplayPort looks like this:

An Apple computer with a Mini DisplayPort will have this symbol next to the Mini DisplayPort:

On Apple portables, iMac, and Mac mini computers the Mini DisplayPort is located with the other ports and connectors. For the Mac Pro, the Mini DisplayPort is on the graphics card. Refer to the manual for your Mac for specific details about the location of ports and connectors on your computer.

3. My computer has the same connector but the symbol is different, what does that mean?

Some Apple computer have a Thunderbolt port instead of a Mini DisplayPort. Computers with a Thunderbolt port will have the following symbol next a port although the port physically appears the same as a Mini DisplayPort:

Thunderbolt ports:

  • Are compatible with all of the Mini DisplayPort adapters referenced below in question 5 and with Apple Mini DisplayPort equipped displays.
  • Support adapters like Apple’s Thunderbolt to Gigabit Ethernet Adapter and Thunderbolt to FireWire Adapter which are not otherwise compatible with Mini DisplayPorts.

See Thunderbolt ports and displays: Frequently asked questions (FAQ) for more information on Thunderbolt.

 

4. What are the system requirements for Apple Mini DisplayPort adapters?

Your computer needs Mac OS X v10.5.6 or later and a Mini DisplayPort to use these adapters. Note: When you use the Apple Mini DisplayPort to Dual-Link DVI adapter, your Mac should also have a free USB port.

5. Which Mini DisplayPort adapters are available from Apple?

Apple Mini DisplayPort to Dual-Link DVI Adapter Dual-link DVI displays with resolutions above 1920 x 1200 Mini DisplayPort to Dual-Link DVI Adapter
Apple Mini DisplayPort to DVI adapter Displays that do not support Dual-link DVI resolutions (DVI displays with a resolution of 1920 x 1200 or lower)
Apple Mini DisplayPort to VGA adapter Displays that connect via VGA  

 

6. Can other video adapters be connected or “daisy-chained” to Apple Mini DisplayPort adapters?

No, you should not connect Apple Mini DisplayPort adapters to any other video adapters. Connect your computer directly to an external display via one Mini DisplayPort adapter.

7. What about HDMI?

Apple does not manufacture a Mini DisplayPort to HDMI adapter. For more information on Mini DisplayPort to HDMI adapters, see this article.

8. What is HDCP?
HDCP (High-bandwidth Digital Content Protection) is a form of digital copy protection that requires compatibility between a source—such as your computer and video adapter if present—and a receiver, such as a high-definition television. If any of these devices or cabling do not support HDCP, your content may not play, may present a warning message, or may play back at a lower resolution than expected. An example of content that supports HDCP is an HD movie on the iTunes Store. Note: For information about whether your cabling, receiver, or television supports HDCP, refer to the manufacturer of the device.

9. Does the Apple Mini DisplayPort adapter support HDCP?
Apple Mini DisplayPort adapters that offer digital connections—such as the Apple Mini DisplayPort to Dual-Link DVI adapter and the Apple Mini DisplayPort to DVI adapter—support HDCP content. Apple Mini DisplayPort adapters that offer analog connections—such as the Apple Mini DisplayPort to VGA adapter—do not support HDCP content.

10. What is the difference between an active adapter and a passive adapter?

An active adapter can convert a signal from one connector to another. The Apple Mini DisplayPort to Dual-Link DVI and Apple Mini DisplayPort to VGA adapters are active adapters. A passive adapter acts as a pass-through from one connector type to another and does not convert a signal. The Apple Mini DisplayPort to DVI adapter is an example of a passive adapter.

11. Should I use a passive or active adapter?

On some Apple computers, like the Mac Pro (Mid 2010), you can connect three displays to a single graphics card. In this scenario—to connect to three display to use three ports—use active adapters to connect the Mini DisplayPort ports to your external displays. Two displays can connect via Mini DisplayPort and one via DVI. Note: Learn more about supported display configurations for the Mac Pro.

12. Can I output via Mini DisplayPort to an RCA or S-Video connection?

No. The Mini DIsplayPort connector allows output to Mini DisplayPort, DisplayPort, VGA, DVI, and HDMI connections when using the proper cables and adapters. However, output to RCA, Component, or S-Video connections is not supported.

13. How is the Apple Mini DisplayPort to Dual-Link DVI adapter different from the Apple Mini DisplayPort to DVI adapter?

The Apple Mini DisplayPort to Dual-Link DVI adapter works best with displays that operate at dual-link resolutions, which are resolutions above 1920 x 1200. For displays that do not support dual-link DVI resolutions (displays that operate at resolutions of 1920 x 1200 or lower) you should use the Apple Mini DisplayPort to DVI adapter instead.

 

14. Which monitors work with the Apple Mini DisplayPort to Dual-Link DVI adapter?

Use the Mini DisplayPort to Dual-Link DVI Adapter to connect your computer to a 30-inch display that includes a dual-link DVI connector, such as the Apple Cinema HD Display. Note: For such displays, be sure to connect the USB connection on the adapter to the USB port on your Mac; also connect the USB connection from the display to the USB port on the adapter.

15. What can I do if my external display is not working properly with the Mini DisplayPort to Dual-Link DVI adapter?

If you are using an external display that is not dual-link DVI, use the Apple Mini DisplayPort to DVI adapter for best performance.

Try these steps if your dual-link DVI display has video issues while it is connected with the Mini DisplayPort to Dual-Link DVI adapter:

  1. Reset the Mini DisplayPort to Dual-Link DVI adapter by disconnecting its Mini DisplayPort and USB connections from the computer for few seconds.
  2. Reconnect the cables to the computer to see if the issues persist.
  3. If your issue is still unresolved, disconnect the Mini DisplayPort to Dual-Link DVI adapter as described in step 1, then power off the monitor.
  4. Reconnect all cables and power on the display.
  5. If issues continue to persist, restart the computer.

16. Why doesn’t the DVI connector for my external display fit my Apple Mini DisplayPort to DVI adapter?

Important: The DVI connector on the Apple Mini DisplayPort to DVI adapter is for digital connections only. Some DVI connectors use additional pins on the connector to send analog information from the display to the computer. Connectors with additional pins are not compatible with the Apple Mini DisplayPort to DVI adapter.

 

Apple DVI to VGA adapter Apple Mini DisplayPort to DVI adapter

The Apple DVI to VGA adapter has four additional pins around the thin connector on the left. Those pins provide an analog signal and are not used with the Apple Mini DisplayPort to DVI adapter.

17. What should I do if I have flickering or compatibility issues with my Apple Mini DisplayPort adapter?

Be sure to install the latest update for your Apple Mini DisplayPort to VGA adapter. If you have flickering issues using your Mini DisplayPort to Dual-Link DVI Adapter with certain displays, learn how to update to an adapter with Firmware version 1.03.

18. What is the maximum resolution available for use with the Apple Mini DisplayPort to VGA adapter?

The resolution available with the Apple Mini DisplayPort to VGA Adapter is 1920 x 1200. VGA displays that use higher refresh rates (such as 85 Hz) at resolutions of 1600 x 1200 or greater may not generate video properly until you lower the refresh rate.

SD and SDXC card slot FAQ

101mac Leave a comment

What is SD?
Secure Digital (SD) describes devices that conform to SD standards for non-volatile memory cards. See the SD Association website for more detailed information.

Are there size limitations for the cards that can be inserted into the SD slot?
Yes. The SD card specification for a memory card is 32 mm by 24 mm by 2.1 mm. You can also use thinner cards, such as MultiMediaCards (MMC). Cards that have a thickness greater than 2.1mm or that have surfaces that exceed 2.1mm should not be used. Do not use cards exceeding this size, which may damage the SD card slot if inserted.

Which SD card formats work in the SD card slot?
Cards that conform to the SD 1.x, 2.x, and 3.x standards should work. The SD card slot can use cards that are Standard SD (Secure Digital) 4 MB to 2 GB, SDHC (Secure Digital High Capacity) 4 GB to 32 GB, and SDXC  (Secure Digital Extended Capacity) 4G B to 2 TB. MMC can also be used in this slot. MiniSD, MicroSD, and higher density formats like MiniSDHC and MicroSDHC can also work with the use of “passive” adapters that conform to the width and thickness specifications listed above.

Example of a passive adapter:

What is the maximum speed that my computer can use when reading and writing to an SD card in the SD card slot?
Macs that use the USB bus to communicate with the SD card slot have a maximum speed of up to 480 Mbit/s. Newer Macs use the PCIe bus to communicate with the SD card slot and can transfer data at a much faster rate.

Check the packaging that came with your SD media to determine the maximum transfer rate used by that specific card.

Determine the maximum speed of your Mac using the System Profiler:

  1. Choose About this Mac from the Apple () menu.
  2. Click More Info.
  3. Select USB from the hardware section (for Macs that use the USB bus to communicate with the SD card slot).
  4. Select Internal Memory Card Reader and look for the Speed entry. or
  5. Select Card Reader from the Hardware section (for Macs that use the PCIe bus to communicate with the SD card slot).
  6. Look for the Link Speed entry. Computers that use the PCIe bus express their speed as GT/s.

Does the SD slot work with cards that exceed 32 GB?
Yes.  However, most media manufactures preformat the media using common block-and-cluster sizes that do not approach the theoretical limits of a given file system. Most SD cards use the FAT32 file format. Preformatted FAT32 SD media is commonly available up to a capacity of 32 GB. Media that exceeds 32GB usually uses the exFAT file system. Some smaller capacity cards use the FAT16 file format. Preformatted FAT16 media is generally available up to a capacity of 2 GB. To determine which file system you are using with Mac OS X v10.6.5 or later, insert the media into the SD card slot, go to the Apple menu, select About this Mac…, click on More info…, click on Card Reader in the hardware section, and locate the File System field.

Will the SD card slot work with SD cards that use the exFAT file system?
Yes. Any Mac computer with an SD card slot and running Mac OS X v10.6.5 or later can use the exFAT file system. Note: If you are running Windows 7 using Boot Camp, the exFAT file system can be used only with the MacBook Pro (Early 2011).

How do I insert media into the SD card slot?
Insert a card with the metal contacts facing down and pointing toward the computer.  Do not force media into the SD card slot.  This may damage the SD card slot.

How does my Mac use the media inserted into the SD card slot?
Your computer recognizes a card inserted into the SD card slot as a USB storage device. The SD card can be mounted, read from, and written to just as any other USB storage device can.

I put the card in the slot, but it did not mount.  What should I do?
Remove the card and insert it again. Sometimes, if you put the SD card into the slot too slowly, it may not mount properly.

When I try to write content to the card, I get a “cannot be modified” message.  How can I fix this?
This message appears when you attempt to modify the contents of an SD card that is locked using the lock slider on the card. To edit data on the card, drag the icon representing the device to the Trash to eject the card. When the icon disappears from the desktop, remove the card from the computer.  Adjust the slider tab to unlock the card, then reinsert the card into the slot. Refer to the manufacturers instructions for the location of the slider tab.

Can I reformat an SD card with Disk Utility?
Yes. Using Disk Utility, you can partition and format an SD device as FAT32 (using the MS-DOS FAT setting) or Mac OS Extended. The Mac OS Extended format can only be used on Macintosh systems. Cards formatted to Mac OS Extended will not be recognized by non-Apple systems. Formatting cards larger than 32GB for use with digital cameras, GPS, and other devices may require formatting them with the exFAT file system. When in doubt, format the cards in the device you intend to use with the card.

Can I install Mac OS X on an SD storage device and use it as a startup volume?
Yes. Change the default partition table to GUID using Disk Utility, and format the card to use the Mac OS Extended file format to do so.

How do I remove a card from the SD card slot?
As with any removable media device, allow any data transfer to SD media to complete before removing the card. When removing the card, the best way to insure the integrity of your data is to drag the icon that represents the card to the Trash, then remove the card from the slot after the icon disappears from your desktop.

Can I use SDIO (Secure Digital Input Output) cards?
No. Although SDIO cards are within the width and thickness specifications and should not damage the slot if inserted, they will not be recognized by the computer.

Can I use OS X to see the specifications for the interface hardware and media inserted in the SD card slot?
Yes. The System Profiler should provide information on the interface hardware and the media you inserted into the slot.  To access the System Profiler, choose About This Mac from the Apple () menu. Click More Info, then select USB in the Hardware section. A list of USB devices should appear. Select Internal Memory Card Reader to access information about the interface hardware and the media inserted into the SD card slot.

Can I use the SD card slot while running Windows using Boot Camp?
Yes. The SD card slot works with Boot Camp in Windows XP, Windows Vista, and Windows 7 Home Premium, Professional, and Ultimate. Note: If you are running Windows 7 using Boot Camp, the exFAT file system can be used only with the MacBook Pro (Early 2011).

Use DVD or USB storage to install Boot Camp drivers?
SD, SDHC, or SDXC cards cannot be used to install Boot Camp software on Macs with an SD or SDXC card slot. For more information on the SD/SDXC card slot.

Some Frequently Answered Questions:

Can a Mac run Windows and Microsoft Office?
Yes. Microsoft Office is available for the Mac, and Word, PowerPoint, and Excel files created on a Mac are fully compatible with Windows. Most other popular applications are available for the Mac, too. But if you need to use a particular Windows-only application, you have a few options: Boot Camp comes with every new Mac, and it lets you run Windows natively — as if your Mac were a PC. If you want to run Mac OS X and Windows side by side, you can purchase Parallels Desktop for Mac or VMware Fusion. Install one of these applications, along with the Windows Installation CDs, and you can run the occasional Windows program right next to your Mac applications, without having to restart.

Is a Mac safe from PC viruses?
Yes. The Mac OS X operating system isn’t susceptible to the thousands of viruses plaguing Windows-based computers. And although no computer connected to the Internet is completely immune to all viruses and spyware, Mac OS X has built-in defenses designed with your safety in mind. The Mac web browser, Safari, alerts you whenever you’re downloading an application — even if it’s disguised as a picture or movie file. And Apple continually makes free security updates available for Mac owners. You can even have them download automatically.

Will my other devices work with a Mac?
A Mac has hundreds of drivers for peripherals preinstalled. Just connect your device and, in most cases, you’re good to go. And a Mac is smart enough to know what to do when you plug in your digital camera: It opens iPhoto and asks if you want to import your recent photos.

Will my keyboard and mouse work with a Mac?
Yes. The Mac is compatible with virtually any keyboard and multibutton mouse, even the ones you use with your PC. Just plug them into the USB ports on your Mac and start working. You can also use the Multi-Touch Magic Mouse or multibutton Apple Mouse, which comes with every iMac and Mac Pro, respectively. And the trackpad on MacBook, MacBook Pro, and MacBook Air offers “right-click” capability — just press the Control key when you click.

Can I work with my existing documents on a Mac?
Yes. A Mac can open most files from your PC, including Microsoft Office documents (Word, Excel, PowerPoint), PDFs, MP3s, iTunes songs, WAV files, JPEGs, GIFs, and more.

Can I join Windows networks?
Yes. If you have a network at home or at work, whether wired or wireless, a Mac will fit right in. You can share files with any computer on your network, browse the web, and get your work or home email.

What about Wi-Fi?
All new Mac computers are Wi-Fi capable. Available wireless networks automatically show up. Just select the network you want to join, enter a password if necessary, and you’re connected.

Is a Mac reliable?
When you buy a PC, you’re buying hardware from one company and an operating system and software from other companies. Not so with a Mac. Because Apple builds both the computer and the software that comes with it, they’re literally made for each other. This means that a Mac rarely freezes or crashes. Occasionally an application might quit, but it won’t affect the rest of your system. And Mac OS X resists most viruses, so you can do anything — without worrying about losing everything.

What software is available for the Mac?
Thousands of titles are available for the Mac. You’ll find everything from Microsoft Office and Rosetta Stone to Adobe Photoshop Elements and Adobe Creative Suite. A huge collection of games covering every genre is available for the Mac, including top sellers such as Age of Empires III, The Sims 2, Guitar Hero III, and many more.

How do I move my files to a Mac?
The best way to transfer your photos, music, documents, and other files is to let us do it for you. When you buy a new Mac from an Apple Retail Store or the Apple Online Store, simply add One to One to your purchase. One to One costs just $99, and it includes Personal Setup, a year’s worth of face-to-face training, and exclusive group workshops. It’s all designed to help you get the most out of your Mac.
If you like, you can transfer your files yourself. And it doesn’t require much work.

Here are two ways to do it:

  1. Copy files from your PC to an external hard drive, connect the drive to your Mac, and move the files over.
  2. Use a local network to move files directly from your PC to your Mac. For detailed information on moving your files to a Mac, read Switch 101: Migrate Your Files or Your Windows System.

Will my current email service work on a Mac?
Yes. You can access your current email in two ways:

View web-based email — such as Gmail, Hotmail, Yahoo! Mail, and MobileMe mail — in the Safari web browser.
Use the Mail application in Mac OS X Snow Leopard. Simply enter your email account information and you’re good to go. If you have email messages in Microsoft Outlook on your PC, you can transfer them to your Mac using inexpensive third-party software.
No matter which method you choose, you can continue using your current email address.

Which web browsers will work on a Mac?
Every Mac includes Safari, the fastest web browser in the world. You can also use Mac versions of Firefox, Opera, and others.

Can I instant message on a Mac?
Yes. Every Mac comes with iChat, Apple’s instant messaging application. iChat supports AIM, Google Talk, and MobileMe. In addition to text messaging, iChat allows you to video chat with friends and family around the world.3 Microsoft and Yahoo! offer Mac versions of their instant messaging applications, too.

What kind of support can I expect?
Every Mac comes with service and support that’s consistently voted the best in the business. If you have a problem in the first year of owning your new Mac, you can take it to an Apple Retail Store to get it fixed or figured out. And if you purchase the AppleCare Protection Plan, you extend your service and support to up to three years from the date of your Mac purchase. The Apple Retail Store also offers services like ProCare, which gives you priority support, and One to One, which provides personal training on your Mac. Each service costs $99 a year.

Is it easy to learn how to use a Mac?
Every Mac is created with the guiding principle that computers should be easy to use, so you can spend more time doing what you love and less time figuring out how your computer works. If you’ve never owned a Mac, you may need a little time to get used to it. But within a week or two, chances are you’ll get along like old friends. And because all Mac applications are designed to work in the same, intuitive way, once you learn one application — iTunes, for example — you’ll quickly pick up iPhoto, Mail, or any of the other software that comes with your Mac.
