Just the Fax.

Q. After applying the latest Mac OS X update on my computer I can no longer send faxes with my Apple USB Fax/Modem.

A. Surprisingly the Mac OS X 10.5.7 software update may affect the settings and your USB modem may stop sending faxes but the fix is easy. Open “Print and Fax” in System Preferences and select your “External Modem” and press the Minus sign to remove it. Then choose “Fax PDF” from the Print menu and your Mac will recreate a new “External Modem” and you can send out faxes.
