This software installer provides software for the MT9234ZBA, MT9234ZBA-USB-CDC-XR, MT9234MU-CDC-XR, MTCBA-C1, MTCBA-C1-U, MTCBA-E1, MTCBA-E1-U, MTCBA-G2, and MTCBA-G2-U. For Mac OS X 10.5 & 10.6 (KEXT 1.0.3 installation required): The USB models (MT9234ZBA-USB-CDC-XR, MT9234MU-CDC-XR, MTCBA-C1-U, MTCBA-E1-U, and MTCBA-G2-U) REQUIRE this kernel extension (MultiModemUSBXR.kext) for Mac OS X 10.5.x (Leopard) and Mac OS X 10.6.x (Snow Leopard) as well as the necessary modem scripts (for dial-up and fax). For Mac OS X 10.7 & 10.8 (KEXT 1.0.3 installation highly recommended): Due to inconsistencies of the built-in USB subsystem in Mac OS X 10.7.x (Lion) and Mac OS X 10.8.x (Mountain Lion), installing this kernel extension (MultiModemUSBXR.kext) for the MT9234ZBA-USB-CDC-XR, MT9234MU-CDC-XR, MTCBA-C1-U, MTCBA-E1-U, and MTCBA-G2-U models is HIGHLY RECOMMENDED. The necessary modem scripts are included in the installation (for dial-up and fax). For Mac OS X 10.9 and newer (KEXT 1.0.4 installation highly recommended): Due to inconsistencies of the built-in USB subsystem in Mac OS X 10.9.x (Mavericks) and Mac OS X 10.10.x (Yosemite), installing this kernel extension (MultiModemUSBXR.kext) for the MT9234ZBA-USB-CDC-XR, MT9234MU-CDC-XR, MTCBA-C1-U, MTCBA-E1-U, and MTCBA-G2-U models is HIGHLY RECOMMENDED. The necessary modem scripts are included in the installation (for dial-up and fax). The serial models (MT9234ZBA, MTCBA-C1, MTCBA-E1, and MTCBA-G2) only require the modem scripts (for dial-up and fax). NOTE: The USB models (MT9234ZBA-USB-CDC-XR, MT9234MU-CDC-XR, MTCBA-C1-U, MTCBA-E1-U, and MTCBA-G2-U) are registered with the system with the name "usbmodem". --- **************************************************************** * Mac OS X MTSModemInstallerXR Customer Release Notes * **************************************************************** Contents: 1) Models Covered By This Firmware/Software 2) Firmware/Software History 3) Support Information **************************************************** * 1 ** Models Covered By This Firmware/Software * **************************************************** - MT9234ZBA (modem script only via installer) - MT9234MU-CDC-XR - MT9234ZBA-USB-CDC-XR - MTCBA-C1 (modem script only via installer) - MTCBA-C1-U - MTCBA-E1 (modem script only via installer) - MTCBA-E1-U - MTCBA-G2 (modem script only via installer) - MTCBA-G2-U **************************************************** * 2 ** Firmware/Software History * **************************************************** -------------------------------------------------- Firmware/Software Version 1.0.4 Timestamp = 06-01-2015 -------------------------------------------------- (a) Features Added/Removed/Modified since 1.0.3: * (06/03/2015 DJS)--Generated a signed installer for the 1.0.4 KEXT. * (06/01/2015 DJS)--Generated a signed KEXT for use with OS X 10.10.x which now enforces the requirement for signed KEXTs.
