Set up a multifunction printer to send faxes from your Mac
If you have a multifunction printer connected to your Mac, follow these instructions to set it up to send faxes.
Note: macOS Sierra and later does not support sending faxes using legacy fax modems. If you’ve used a fax modem in the past with your Mac, you may be able to continue using it to send and receive faxes by installing third-party fax software. You can also try using an internet faxing service. For more information, search the internet for “fax software” or “internet fax service.”
Follow the instructions that came with the printer to set it up and connect it to your Mac.
On your Mac, choose Apple menu > System Preferences, then click Printers & Scanners.
If you don’t see your multifunction printer in the list at the left, click the Add button . If a pop-up menu appears, choose Add Printer or Scanner.
Select your printer in the list, click the Use pop-up menu, choose the version of printer software that supports faxing, then click Add.
For information about which software to choose, see the Apple Support article Printer and scanner drivers for Mac.
If your multifunction printer is compatible with macOS Sierra or later, the fax capability is added automatically when you add the printer. If you can’t add the printer as a fax machine, see the documentation that came with the printer to find out how to use it to send and receive faxes.
As an alternative to faxing, consider scanning your document and saving it as a PDF or in another text format that you can email. You may also be able to send and receive faxes with an internet faxing service.
