The Apple Remote is a remote control device released in or after October 2005 by Apple Inc. for use with a number of its products which use infrared capabilities. The device was originally designed to interact with the Front Row media program on the iSight iMac G5 and is compatible with some later desktop and portable Macintosh computers. The first three generations of Apple TV used the Apple Remote as their primary control mechanism. It has now been replaced with the Siri Remote in the fourth generation. Prior to the Apple Remote, Apple produced several nameless IR remotes for products such as the Macintosh TV, TV tuner expansion boards, and the PowerCD drive.

Design
The original Apple Remote was designed with six buttons and made of white plastic. Its shape and layout resembled the first-generation iPod Shuffle. A circular Play/Pause/Select button sat in the center of a larger four-button circle of (clockwise): Volume Up, Next/Fast-forward, Volume Down and Previous/Rewind. A separate Menu button was positioned below. The price was set at US$29.00.
In October 2009, the remote was redesigned as a thinner and longer aluminum version. The new remote was released along with the 27 inch aluminum iMacs and multi-touch Magic Mouse. The Play/Pause button was moved out of the center of the directional buttons and put beside the Menu button (under the directional buttons). The symbols for the Volume Up/Down and Next/Fast-forward buttons were replaced with small dots, to make it clear that the buttons were also used to move up, down, left, and right within menus. All of the buttons became black and embossed within aluminum. Along with the new design, the price was dropped to US$19.99. The newer design also underwent a slight revision with the navigation ring. In a small percentage of older remotes, this ring was flush with the curvature of the remote's aluminum body. The more-common revision is bulged slightly; presumably so users can find the ring more easily by touch.
Replacement of the CR2032 battery in the original remote is done with a small pointed object such as a paper clip at the bottom right edge of the device, where the battery slides out on a tray. The newer version has the battery located behind a compartment in the middle of the device which is accessed by turning a coin in the compartment door's indent.

Functions
The Apple Remote's original function was to enable navigation in Front Row, which allows users to browse and play music, view videos (DVDs and downloaded files) and browse photos. Although Front Row was removed from OS X 10.7 and later, some Apple software still works with the remote. It can still be used to control presentations in Apple Keynote (on both Intel Macs & PowerPC Macs), picture slide shows in iPhoto and Aperture, DVD films via DVD Player, and to play video and audio in iTunes and QuickTime. Other software that is still compatible includes Elgato's EyeTV 3.5, and VLC media player. The remote can also be used to run presentations in Microsoft PowerPoint 2008 or in OpenOffice.org Impress.
Other functions controlled by the remote can include putting a device into sleep mode, selecting a partition to boot from on startup, and ejecting optical disks. A device can be configured to respond only to a particular remote.
iPods
An iPod placed in a dock featuring an IR sensor can be used with the remote for music and media control. The remote's menu functionality does not work on the iPod. The Apple Remote can also be used to control the iPod Hi-Fi or third party devices tailored to it.
Boot Camp
Starting with Boot Camp 1.2, the remote has had some functionality when a user is running Windows. If iTunes is installed on the Windows partition, pressing the Menu button on the remote will load the program. The remote's media controls also support Windows Media Player, as well as system volume control. Other third party programs may also utilize the remote's capabilities; media applications such a foobar2000 and Media Player Classic allow users to control their functions via the remote. Applications must be in focus for the remote to control them. Boot Camp 5, the latest version of the software, also includes drivers for the remote control.
iOS App
Apple offers a free 'Remote' app for iOS devices (available in the Apple App Store) which allows for wireless control of iTunes on Mac/Windows computers or the Apple TV.
The Fourth Generation Apple TV and the Siri Remote
The Siri Remote was launched with the 4th Generation Apple TV in 2015. It uses both IR and Bluetooth to communicate with the Apple TV. The remote bares a glass trackpad, dual microphones, 5 buttons for Menu, Home, Siri and Play/Pause, Volume up and down as 1 button and is the size of 2 buttons. Additionally it has an accelerometer (IMU) and a gyroscope which allows the remote to be used as a gaming controller for tvOS apps and games. The remote (unlike previous generations) uses a built-in rechargeable Lithium Polymer Battery that is charged through the lightning port at the bottom of the remote. The Siri Remote is known as the Apple TV Remote in places that don't support Siri.
Compatibility
Earlier models of the iMac (Polycarbonate iMac) featured a magnetic rest for the remote, which was later removed.
Use with new MacBook Airs, Retina MacBook Pros and older Macs
Using the Apple Remote with new MacBook Airs, Retina MacBooks or old Macs without a built-in IR Receiver requires a USB-based infrared receiver and additional software from a third party.
Using Remote Buddy (from IOSPIRIT GmbH) or mira (from Twisted Melon), it is possible to connect an external USB receiver such as the Windows Media Center Edition eHome receiver, and use the Apple Remote on these machines with full support for sleep, pairing, low battery detection and controlling a variety of Apple and third party software. In addition, Remote Buddy is able to emulate events of an Apple Remote on these systems, enabling users to use software written for the Apple Remote in exactly the same way as with Macs that have a built-in infrared receiver.
Infrared interference
Because many electrical appliances use infrared remote (IR) controls, concurrent use of the Apple Remote with other IR remotes may scramble communications and generate interference, preventing stable use. Remotes should be used individually to circumvent the problem.
Technical details
The Apple Remote uses an NEC IR protocol[1] which consists of a differential PPM encoding on a 1:3 duty cycle 38 kHz 950 nm infrared carrier. There are 32 bits of encoded data between the AGC leader and the stop bit:
While the Apple Remote uses the NEC IR protocol for the timing, the 32-bit data package is in a different format. It consists of two 16 bit LSB words.
