You just unboxed it. Or maybe you just wiped it clean to start fresh. That beautiful, crisp "Hello" screen stares back at you in thirty different languages, and you’re ready to dive into macOS. Then, the wall hits. You're stuck at the activation lock or the initial setup screen, and for whatever reason—a dead router, a corporate firewall, or a broken internal antenna—you have no internet.
Trying to activate Mac no WiFi feels like being locked out of your own house while holding the keys.

Apple’s security architecture, especially since the introduction of the T2 security chip and Apple Silicon (M1, M2, M3, and M4 chips), is basically a fortress. It wants to talk to Apple’s activation servers before it lets you past the front door. It's a theft-prevention measure, sure, but it’s a massive headache when you’re offline.
Most people think you're just dead in the water. Honestly? You aren't. But it isn't as simple as clicking a "skip" button like it was in 2012.
Why Does macOS Demands a Connection Anyway?
It’s all about the Activation Lock. When a Mac is erased or set up for the first time, it checks the serial number against Apple's database. This confirms the device isn't reported stolen and isn't linked to someone else's iCloud. This "handshake" requires data.
If you're on an older Intel Mac without the T2 chip, you might actually be able to bypass some of this. But if you're on anything modern? The hardware is hard-coded to demand that server handshake.
The Ethernet Lifeline (The Most Reliable Fix)
If your WiFi is the problem—maybe the drivers aren't loading or the signal is just junk—the absolute best way to activate Mac no WiFi is to stop trying to use wireless altogether.
You need a hardline.
If you have a MacBook Pro or Air, you’ll need a USB-C to Ethernet adapter. Most people have one of these buried in a drawer or can snag one from a friend. Plug that into your Mac and run a cable directly to your router.
The Mac is smart. Even on the activation screen, it will prioritize a detected Ethernet connection over WiFi. Usually, the moment you plug it in, the "Next" button that was greyed out suddenly turns blue. It feels like magic, but it’s just basic networking.
Using a Tethered iPhone (The Secret Weapon)
Maybe your home internet is totally out. Maybe you're in a hotel where the WiFi has one of those annoying "splash pages" that the Mac setup screen can't render.
Use your phone.
But don't just turn on a Hotspot. Sometimes the Mac won't see the Hotspot in the setup menu. Instead, use a physical tether. Take your USB-C to Lightning (or USB-C to USB-C for iPhone 15/16 users) cable. Plug your phone into the Mac. On your iPhone, go to Settings > Personal Hotspot and make sure "Allow Others to Join" is on.
Your Mac should treat the phone as a wired network interface. This bypasses the need for the Mac to search for SSIDs or deal with weak radio signals. It just draws the bits it needs to tell Apple, "Hey, I'm a legitimate computer, let me in."
What If the WiFi Menu Is Missing Entirely?
This is a nightmare scenario. Sometimes, after a botched update or a weird recovery mode glitch, the WiFi icon doesn't even show up in the top right corner of the activation screen.
You might think the hardware is fried. It’s usually not.
You can try to trigger the terminal. On many setup screens, you can access utility menus. If you can get to the Recovery Environment, you can sometimes use the networksetup command-line tool to force a connection, though that's getting into the weeds.
A more "human" fix? Restart. Seriously. Hold the power button, kill it, and start over. On Apple Silicon Macs, holding the power button takes you to "Startup Options." From there, you can sometimes find a hidden WiFi selection menu in the top right that wasn't appearing in the standard "Hello" flow.

The "Check Coverage" Trick
I've seen this work in a pinch when the standard activation screen hangs. If you can get to the "Recovery" screen instead of the standard "Setup Assistant," there’s often a "Help" or "Safari" link.
Opening a basic browser window within the recovery environment can sometimes force the OS to initialize the network stack. Once the Mac realizes it has a path to the internet, the activation process in the background often "wakes up" and completes itself.
Dealing with MDM (Mobile Device Management)
If you bought this Mac used and it’s asking for a connection to a specific company’s server, you aren't just dealing with an activation issue. You're dealing with Remote Management.
In this case, trying to activate Mac no WiFi is even harder because the Mac is specifically looking for a corporate configuration profile. If you're offline, it can't download the profile, but it also won't let you proceed without it.
If you're stuck here, you absolutely need a connection. There is no legal or functional way to "skip" a corporate MDM lock without an internet connection, as the serial number is flagged in Apple's Business Manager.
For the Older Macs (Pre-2018)
If you're rocking an older machine, you have a lot more freedom. You can actually create a bootable USB installer on another computer.
- Download the macOS installer (Ventura, Monterey, etc.) on a working Mac.
- Use the
createinstallmediacommand in Terminal to put it on a flash drive. - Boot your offline Mac from that drive by holding Option (Intel) during startup.
When you install macOS this way, you can often skip the "Sign in with Apple ID" and "Connect to Network" steps during the initial setup by selecting "My computer does not connect to the internet." This option has largely disappeared on newer M-series Macs because of the security enclave requirements, but for a 2015 MacBook Air? It works like a charm.
The Reality of Apple Silicon
Let's be real: Apple wants you online. On an M1, M2, or M3 Mac, the "Activation" step is a literal hardware check. The internal Secure Enclave has to verify its UID with Apple’s servers.
If you are truly in a dead zone with no phone service, no Ethernet, and no WiFi, you cannot activate a modern Mac. It’s a brick until it sees the internet for at least thirty seconds.

I've seen people drive to a Starbucks parking lot just to get that 30-second handshake done. It's annoying, but once that activation "ticket" is stored in your Mac's hardware, you won't need to do it again unless you wipe the drive.
Summary of Actionable Steps
Don't panic. If you're staring at that screen and feeling the heat, follow this sequence:
- Find a Dongle: Borrow or buy a USB-C to Ethernet adapter. It is the only 100% "no-fail" method.
- Wired Hotspot: Plug your iPhone directly into the Mac. It's more stable than wireless hotspotting.
- Recovery Mode: If the WiFi icon is missing, shut down and hold the power button to enter Options. Check the top-right corner for a hidden network menu.
- External Boot: If it's an older Mac (pre-T2 chip), use a bootable USB installer to bypass the need for a network during the OS installation.
- Check the Time: If you get an "Activation Server Unavailable" error, it's often because the Mac's internal clock is wrong. Go to Terminal in the Utilities menu and type
dateto see if it’s set to 1970. If it is, you can manually set it using thedatecommand (MMDDHHmmYY format), which often fixes the connection error.
Once you get past that initial handshake, you can go back to living the offline life. But for those first five minutes, the Mac needs to talk to the mothership. Get it that connection by any means necessary—even if it means a tethered phone and a prayer.
