How do I stream audio from my Mac to my TV or stereo receiver?

A: There are two main ways to wirelessly stream your digital content.

One way is to use an Apple TV. It connects to your TV or receiver and streams a variety of iTunes-stored media content – including movies, music, photos, podcasts, and TV shows – to your TV.

To stream only audio, use AirPort Express. It's a wireless router that can send audio from iTunes to your TV or stereo. Current Mac computers support both analog and digital audio out through the 3.5mm mini-jack (3.5mm). Check the audio-in capabilities of your TV/stereo receiver. Then use the appropriate cable to connect your TV or stereo to AirPort Express. The most common solutions are either a mini-jack (1/8-inch) to RCA cable or a mini-jack optical (1/8-inch) to Toslink cable.

Can I record TV on my Mac?

A: Yes. You can record over-the-air broadcasts using the Elgato EyeTV Hybrid TV Tuner. This device allows you to watch and record live TV right on your Mac.

How do I use an XLR device?

A: Plug your XLR device into a digital audio interface device. Then connect that interface to your Mac via FireWire or USB.

How do I hook up external speakers?

A: Most speakers will connect through the USB or 1/8-inch audio out port on your Mac. Professional sets that use XLR or 1/4-inch connections require an external audio interface device to convert the digital signal from your Mac to the analog configuration of your speakers. On many newer Mac computers, the 1/8-inch jack doubles as a mini TOSLink interface, allowing for digital optical out. Digital optical out is popular on many home cinema and audiophile setups with a dedicated amplifier.

What are the basics?

A: All Mac computers include USB 2.0, Ethernet, and FireWire 800 ports (except for MacBook, which does not include FireWire).

How do I share a hard drive with other computers?

A: All Mac computers are designed to share drives seamlessly using Sharing in System Preferences. They can also read the contents of a PC-formatted disk. However, a PC can read the contents of a Mac formatted drive only if third-party software is included. If you want to transfer files between your Mac and a PC more easily, format the external drive as FAT32 – a file system that is both Mac- and PC- compatible.
