Apple Modem
The Apple USB Modem is a combined 56 kbit/s data modem and 14.4 kbit/s fax external USB modem introduced by Apple Inc. after the internal 56k modem was dropped on the October 12, 2005 iMac G5 revision. While it looks identical, it should not be confused with Apple's optional USB Ethernet Adapter accessory, available for its MacBook Air and MacBook Pro Retina range of laptops since 2008.
==History==
Apple introduced its first true modems in 1984, the ''Apple Modem 300'' & ''1200'' modems (V21/V22). Prior to that they offered a third party Apple-badged comparatively low-tech acoustic coupler. Those were followed by the industry standard 2400/data and combined 9600/fax (V29) ''AppleFax Modem'' in 1987. Apple introduced the internal 2400 data/fax modem card for its Macintosh Portable in 1989 as well as released its last external desktop ''Apple Data Modem 2400''. Only standard internal modems were offered during the 1990s through 2005, with the notable exception of Apple's foray into GeoPort passive telephony modems which relied heavily upon the computer's software and processing power rather than dedicated hardware (like Apple's proprietary internal ''Express Modem''). The ''Apple USB Modem'' is Apple's first true external modem since the ''Apple Data Modem 2400'' was discontinued in 1992.
As of September 2009 it is no longer available in the US Apple Store, but it still works (at least for fax) as of Mac OS X version 10.6.2. No officially supported 64-bit driver exists, and as Mac OS X Lion operates by default in 64-bit mode, the USB modem will not function in Lion without workarounds.
