Choosing the correct Laptop Adapter for your Macintosh may seem like a daunting task at first, but it does not need to be. There are many different types of technology that are available for interfacing with the Macintosh platform. Fortunately, for many peripherals at least, Apple has elected to go with the Universal Serial Bus or USB connector. This device is identified by its small, rectangular, and metallic appearance. Moreover, most pieces of USB equipment are stamped with a logo resembling a trident. For devices like external laptop computer keyboards, mice, and many other types of add on apparatuses, USB interfaces need no further action from the user. Even some legacy devices, like external floppy drives, will connect with a USB adapter. Like the USB port, the Ethernet laptop adapter has Macintosh support. It is a networking adapter that uses the RJ45 connector.

Both the RJ45 connector and the Ethernet port closely resemble regular commercial phone jacks and plugs. Therefore, anyone who is using legacy dialup technology as well as fiber optic local area network applications should take great care not to mix up the two connectors. The IEEE 1394 High Speed Serial Bus Standard, well known to Apple users as Fire Wire, provides support for many consumer products. This connector is slightly less forthcoming due to its visual design. It comes in either a four or six circuit adapter plug that closely resembles a USB plug, or another style that resembles an Ethernet adapter. However, this laptop adapter has had Macintosh support since its development, which was spearheaded by Apple’s own designers.

A Fire Wire adapter will not fit into an Ethernet or USB port, usually, so users should take care to not force these types of adapters into ports for which they were not designed. Most wireless network adapters will have Macintosh support through one of these other types of systems. Whether using an Apple Airport system, or a more conventional Wi-Fi system, the system most likely will connect to the laptop in one of these fashions. One of the larger exceptions is the realm of internal Wi-Fi cards, which may or may not have Macintosh support. One should contact the manufacture of the card to see if they are able to interface with an individual Macintosh laptop. Of course, the most common type of adapter used with Macintosh systems is the AC power adapter. This is a more self-explanatory, and user friendly, system than any of the other adapters that an individual might find on their Macintosh laptop. Such a system would be nothing more than the actual device that connects the computer to its power source. Generally, the power supply is not user-serviceable, and users should not concern themselves with it.
