Apple USB Modem

Apple USB Modem is a small external modem dongle that was marketed by Apple.

Description
The Apple USB modem supports Macs running Mac OS X 10.4.3 "Tiger" or later with a USB 2.0 connection. It utilizes a chipset, but relies on a deprecated 32-bit driver that began exhibiting compatibility issues in Mac OS X Lion (10.7) and is no longer functional under macOS Catalina (10.15) and later.

This external modem resembles the Apple USB Ethernet Adapter, although the two use unrelated connection methods.

Release
The external modem first became available on October 12, 2005 as a bundled option with the iMac G5 with iSight camera as it no longer contained an internal modem. It soon became available as a separate item.
