Josh Wright over at Macgasm figured out a really clever way to do just this very thing, using simply a copy of Lion, a MacBook Air Recovery USB Drive, a Windows machine (virtual or physical) and a. USB generally works great. But given all the devices that use USB, you may run out of available ports. In that case, you can buy a USB expansion hub — preferably one that you can plug in to an electrical outlet. The state of the art for USB ports is USB 2.0. Older Macs have slower USB 1.1 ports.
- Use this information to find out which MacBook Air you have, and where it fits in the history of MacBook Air. Your Mac provides several tools to help you identify it. The simplest is About This Mac, available by choosing About This Mac from the Apple ( ) menu in the upper-left corner of your screen.
- If you would like to give it a go to recover your data, the following shows how to recover data from dead MacBook Air using Mac Data Recovery. Download the software on a spare Mac and install it. Plug-in a blank USB drive to your Mac, open the software, select the option that says Recover Data from Crashed System, and click on Start.
USB port types and names
USB (Universal Serial Bus) is an industry standard for connecting computers and other devices. It's available with many types of ports, and each type has a unique shape. On Mac computers, USB is available with these ports, depending on your Mac model:
USB-A
Type USB-A ports are commonly called USB, USB 2, or USB 3 ports, depending on the USB specification they support. They aren't reversible, so a USB-A connector plugs into the port only when oriented correctly. Stellardrivedefrag 3 0.
USB-C
Type USB-C ports are available as either standard USB-C ports or Thunderbolt 3 ports that also support USB-C connections. They both look the same, and the connector plugs into the port in either orientation.
Learn more about identifying the ports on your Mac, as well as the adapters and cables you can use to connect older devices to type USB-C ports.
USB specifications
USB specifications are important primarily when you want the most speed and power for your USB device, or your device needs more power or is using too much power. Every USB port supports a particular USB specification, which determines the port's maximum>USB specifications on MacData transferPowerUSB 3.1 Gen 2

To learn which specification is supported by a type USB-A or type USB-C port on your Mac model:
- Choose Apple menu > About This Mac, click Support, then click Specifications.
- Check the System Information app for more details, including about USB devices connected to USB ports on your Mac. Select USB in the sidebar, then select a USB bus on the right.
Get the best performance from your USB devices
USB specifications all work with each other, but speed and power are limited by the cable or device that uses the earliest specification. For example, if you connect a USB 3 device to USB 2 port, your device is limited to USB 2 speeds, and it can't draw more power from the port than can be delivered over USB 2. In other words, to get the best performance, make sure that the USB port on your Mac and the USB cable to your device meet or exceed the USB specification of the device itself.
If your Mac doesn't recognize a USB device after you plug it into your Mac:
- Check all connections: Unplug the device from your Mac, then plug it back in, and make sure that all cables and adapters are securely connected at both ends. Test with another cable or adapter, if available.
- Plug the device directly into your Mac instead of a USB hub or other device, and if necessary test with a different USB port on your Mac or device.
- Some devices need their own software, such as drivers or firmware. Others work without additional software. Check with the maker of your device, and install all available Apple software updates as well.
- If your device came with an AC power adapter, use it. Some devices can be powered by the USB port on your Mac. Others need more power than your Mac can provide.
- Restart your Mac.

Your Mac provides several tools to help you identify it. The simplest is About This Mac, available by choosing About This Mac from the Apple () menu in the upper-left corner of your screen. The other is the System Information app. Learn how to use these tools to identify your Mac.

If you don’t have your Mac or it doesn’t start up, use one of these solutions instead:
- Find the serial number printed on the underside of your Mac, near the regulatory markings. It’s also on the original packaging, next to a barcode label. You can then enter that serial number on the Check Coverage page to find your model.
- The original packaging might also show an Apple part number, such as MQD32xx/A (“xx” is a variable that differs by country or region). You can match the Apple part number to one in the list below to find your model.
