How To Fax On Mac

This article was updated in December 2025

The Short Answer: Macs no longer have built-in fax modems. To fax from a Mac in 2025, you have three options:

1. The “Hardware” Way: Connect a multifunction printer (slowest, requires a landline).
2. The “Ecosystem” Way: Use iPhone Mirroring or a Mac app to fax wirelessly (fastest for macOS Sequoia users).
3. The “Corporate” Way: Send a fax directly from your Email client.
4. The Online Way: Use an electronic fax service in your browser (good for one-offs).

Here’s a quick comparison table with all the options:

Method	Best For	Speed	Cost	Setup Difficulty
Printer + Landline	Offices with hardware	Slow	High (Hardware)	High
Fax App	Everyday users	Fast	Moderate	Easy
Email-to-Fax	Hospitals, legal firms	Medium	Moderate	Easy
Online Fax	One-offs	Medium	Low	Very Easy
Free Fax	Rare emergencies	Slow	Free	Very Easy

The “Old School” Way: Using a Multifunction Printer

Look, if you really want to relive the office vibes of 2005, macOS does technically support faxing the old-fashioned way. It feels a bit like plugging a VCR into a modern 4K TV, but hey—it works if you have the hardware.

Apple hasn’t put a fax modem inside a Mac for over a decade, but the software to handle one is still buried deep in your System Settings. If you happen to have a multifunction printer (the big chunky ones that scan, print, and fax) and an active landline, you can wire your Mac directly to it.

Here is how to do it (if you have the gear):

1. Plug it in: Connect your Mac to the printer via USB (or Wi-Fi if it’s a newer model) and—this is the kicker—make sure the printer itself is plugged into a live telephone wall jack.
2. Go to Settings: Open System Settings (or System Preferences on older macOS) and head to Printers & Scanners.
3. Find the Fax: If your printer is connected properly, you should see a specific “Fax” version of your printer in the list.
4. Send it: Open the document you want to fax (like a PDF or Word doc), hit File > Print, and in the printer dropdown menu, select that “Fax” version. Instead of printing ink on paper, it’ll ask for a fax number and dial out through the landline.

The verdict? It works, but it’s heavy on the “setup” side. You need a physical phone cord, a paid landline subscription, and a printer that probably hasn’t had a firmware update since I was in high school. It’s reliable, sure, but for most of us working from a coffee shop or a home office without a landline, it’s a non-starter.

2. The Modern Way: Using a Fax App (Municorn)

If you don’t have a landline (and who does?), the standard solution in 2025 is to use a dedicated fax app. These apps act as a “virtual bridge,” taking your digital file and transmitting it over the phone network for you.

There are plenty of options on the App Store (eFax, Fax.Plus, etc.), but for this guide, we’ll focus on the Municorn Fax App because it has the best integration with macOS features like iPhone Mirroring.

There are two ways to use it on your Mac: the “Ecosystem Hack” (my favorite) or the Native Mac App.

Option A: Use iPhone Mirroring (The “Ecosystem” Hack)

If you’re keeping up with Apple’s latest software updates, you probably saw the buzz around iPhone Mirroring in macOS Sequoia. Honest opinion? It’s one of those features that looks like a gimmick until you actually try it—then you wonder how you lived without it.

This is arguably the coolest way to fax because it bridges the gap between your Mac and your iPhone perfectly.

Here is why I actually use this method the most:

• It feels native: You get to use your Mac’s keyboard and trackpad to type out cover pages (way faster than thumb-typing).
• Access to Mac files: You can drag and drop files from your desktop directly into the mirrored iPhone window.
• No phone line needed: Since the app uses your Wi-Fi or data connection, you are effectively turning your MacBook into a fully capable fax machine without needing a copper landline or a clunky printer.

How to get it working:

First, make sure your Mac is running macOS Sequoia (or later) and your iPhone is on iOS 18. Both need to be signed into the same Apple ID with Bluetooth and Wi-Fi on.

1. Click the “iPhone Mirroring” icon in your Mac’s Dock. Your phone creates a seamless connection, and your iPhone screen will pop up on your Mac’s desktop like magic.
2. Open the Fax App: Use your mouse to click the Municorn icon on that mirrored screen.
3. Send your fax: Just like on your phone, hit “New Fax.” You can pull documents from your iCloud Drive, Google Drive, or just snap a photo if your phone is propped up nearby.

It’s the best of both worlds—the simplicity of the mobile app, with the productivity of your Mac setup.

Option B: Download the Native Mac App

Step 1. Download the app Search “Municorn fax app” in the Mac App Store. Once installed, it looks and feels similar to the iPhone version but is optimized for your bigger screen.

Step 2. Get your fax number The app allows you to claim a local fax number in the US, UK, Canada, and beyond. You don’t need to be in that city to have a number there—great for appearing “local” to clients.

You can then choose your number from the available options – as you can see, there are many to choose from in all regions.

When your fax number is ready, it will appear on screen, and is easily accessible and shareable from your inbox page in the app.

Step 3. Prepare and Send Navigate to the ‘New Fax’ homepage. You can drag and drop Word docs, PDFs, or images straight from Finder. The best part? You can attach files from Google Docs or Microsoft Word without converting them first. The app handles the conversion for you.

Step 4. Review your fax and hit send. This is a good chance to check the recipient’s fax number and add your fax pages and cover page. Before you send your fax, you can preview the fax, and get information from the app about how long the fax will take to send. Each page usually takes around a minute or two to fax, so this helps you know when your recipient can expect their delivery.

Once your fax has sent, your app (on both your Mac or your iPhone) will receive a notification – this means you can hit send, and then leave your Mac if you want to go and do something else – the notification will come through on your phone!

3. The “Corporate” Way: Email-to-Fax

If you’re the kind of person who lives inside Apple Mail or Outlook, downloading a separate app just to send one document might feel like digital clutter.

The good news is you can actually fax straight from your inbox using an Email-to-Fax service. Think of this as a “translator” layer: you send a regular email, the service catches it, converts it into analog fax signals, and delivers it to the recipient’s machine.

This is a favorite method for lawyers and healthcare pros because it combines the ease of email with the legal security of faxing. Services like EveryFax are HIPAA-compliant, meaning they wrap your document in a layer of encryption that standard email just doesn’t have.

Here is exactly how to do it:

1. Compose: Open your email client (Mail, Outlook, Gmail—doesn’t matter) and start a new message.
2. Address It: In the “To” field, you won’t type an email address. Instead, type the recipient’s fax number followed by the service’s domain.
   • Example: If you are using EveryFax, it would look like [email protected].
3. Attach: Drag and drop your documents into the email.
   • Note: You don’t need to convert them first. Whether it’s a PDF, Word Doc, or a JPEG, the service will automatically convert them into fax pages in the order you attached them.
4. Send: Hit send. You’re done.

After a few minutes, you’ll receive an automatic confirmation email in your inbox telling you the fax was successfully delivered. It’s the best option if you want to keep a strict “paper trail” of everything you send without leaving your email workflow.

4. The Browser Way: Online Fax Services

If you don’t want to download any apps, you can use a browser-based service. These work on Safari or Chrome and allow you to fax from any Mac you log into.

Here are a few of the top competitors we’ve tested:

eFax

eFax is the “legacy” giant of the industry. They offer a web portal where you log in, upload a document, and hit send.

What I like: eFax has a huge range of platforms to access it from – apps for iPhones or Android devices, a web platform, and email-to-fax, meaning you don’t just need a Mac to use it. It’s also incredibly secure (ISO 27001 certified) and reliable.

What I don’t like: The interface feels a bit “Windows 95.” It’s clunky compared to modern apps. Also, their basic plans often have strict page limits (e.g., 30 pages/month), whereas Municorn offers unlimited options.

Fax.Plus

Fax.Plus is another top online fax service which supports faxing from Mac computers via web browsers, email, or with a mobile app. Fax.Plus allows you to create a free account to try it before you buy it, and overall feels like a very premium experience.

The easiest way to fax from Mac with Fax.Plus is by using the web browser service, which has a simple and intuitive layout and is easy to use. If you’re struggling, however, their YouTube channel can talk you through the process.

What I like: The design is clean and matches the “Mac” aesthetic better than eFax.

The Catch: Watch out for the “transmission time” pricing. Some plans charge you for 2 pages if 1 page takes longer than a minute to transmit.

5. Free Options (With Limits)

Faxing costs money because it uses real telephony infrastructure. However, if you only need to send a one-off page and don’t care about cover sheets, there are limited free options.

FaxZero: Offers 5 free faxes per day. It’s reliable but adds a “FaxZero” branding logo to your cover page, which might not look professional for business documents.

GotFreeFax: Allows 2 free faxes per day (US/Canada only). No sign-up, but the quality is mid-tier.

Final Verdict: Which method is best for Mac?

• For Speed & Power: Use Method 2 (Municorn App) via iPhone Mirroring. It’s the fastest workflow for anyone in the Apple ecosystem.
• For One-Offs: Use a browser service.
• For Lawyers/Doctors: Use Method 3 (Email-to-Fax) for that paper trail.
