You’re standing there, phone in hand, hovering over your MacBook like it’s a magic trick that won't trigger. You click share. The little circle spins. And spins. Nothing. It’s one of those tech frustrations that feels personal, honestly. When you have AirDrop not working MacBook issues, it usually happens exactly when you’re in a rush to move a massive PDF or a batch of vacation photos.
Apple’s "it just works" marketing feels like a joke when your laptop stays invisible to your iPhone.

Most people think it’s a broken antenna or a fried logic board. It rarely is. Usually, it’s a weird handshake protocol error or a buried setting that toggled itself off during a macOS update. Let’s get into the weeds of why this happens and what actually moves the needle when you’re staring at a dead transfer bar.
The "Everyone" Setting and Other Visibility Lies
The biggest mistake is trusting the "Contacts Only" setting. Look, we all want to be private. But Apple’s iCloud contact syncing is notoriously finicky. If your MacBook isn't perfectly synced with the Apple ID on the sending device, "Contacts Only" basically acts like a brick wall.
Change it to "Everyone" for ten minutes. Just do it.
Go to your Control Center in the top right of your macOS menu bar. Click the AirDrop icon. Switch it to Everyone. You’ll probably see your device pop up instantly on the other screen. If you’re worried about random people in the coffee shop sending you memes, you can set it to "Everyone for 10 Minutes" on newer macOS versions like Sonoma or Sequoia. This bypasses the entire iCloud validation mess which is often the silent killer of file transfers.
Bluetooth and Wi-Fi: The Messy Relationship
AirDrop isn't just Wi-Fi. It’s a hybrid. It uses Bluetooth Low Energy (BLE) to "advertise" that the Mac is there and then creates a peer-to-peer Wi-Fi network to move the heavy data.
If your Wi-Fi is connected to a 5GHz band but your phone is struggling on a 2.4GHz band, things get weird. Sometimes they just won't talk. Toggle them both off and on. Not just a quick click—turn Bluetooth off in System Settings, wait five full seconds so the radio chip actually resets, and then kick it back on.
Don't Hide Behind Your Firewall
Many "power users" break their own AirDrop. If you’ve gone into System Settings > Network > Firewall and turned it on, you might have accidentally checked the box that says "Block all incoming connections." AirDrop needs incoming connections. It’s literally an incoming connection.
Go into your Firewall Options. Make sure "Block all incoming connections" is unchecked. Also, ensure "sharingd"—the background process that handles AirDrop—is allowed to receive connections. Without this, your Mac is basically wearing an invisibility cloak that even Apple’s own tools can’t see through.
The Sleep Problem Nobody Mentions
Your Mac can't receive a file if it's half-asleep. Even if the screen is on, sometimes the wireless card enters a low-power state. This is especially true on M1, M2, and M3 MacBooks trying to save battery.
If you're trying to send a file to a closed MacBook in "Clamshell Mode," stop. It’s probably not going to work unless you have an external monitor and power connected. Open the lid. Wake it up. Make sure the Finder is the active window. For some reason, having a Finder window open and set to the AirDrop tab acts like a beacon for the protocol. It’s old school, but it works when the Control Center toggle fails.
The "Killall" Command for When You're Done Clicking
Sometimes the software process responsible for AirDrop just hangs. It’s a daemon called sharingd. You can click the menu bar until your finger hurts, but if that process is frozen, nothing happens.
Open Terminal (Command + Space, type "Terminal").
Type this: killall sharingd
Hit Enter. You won't see a confirmation message, but the process will instantly restart. This is the "pro" way to fix AirDrop not working MacBook glitches without restarting the entire computer. It forces the sharing subsystem to re-index available devices and clear its cache.
Hardware Interference and Physical Barriers
We forget these are radio waves. If you have your MacBook sitting on a metal desk or right next to a massive USB-C hub that isn't shielded properly, the 2.4GHz interference can drown out the Bluetooth "discovery" signal.

USB-3.0 hubs are famous for leaking interference that kills Bluetooth.
Try unplugging your accessories. It sounds like "voodoo" tech support, but there are countless reports on the Apple Support Communities where a cheap HDMI adapter was the sole reason AirDrop wouldn't connect. The adapter leaks noise that matches the frequency of the Bluetooth chip, effectively jamming the signal.
Version Mismatch and Legacy Hardware
If you are using an "Obsolete" or "Vintage" Mac, be aware that AirDrop changed significantly around 2014. Older Macs used a different protocol that worked Mac-to-Mac but not Mac-to-iPhone. If you’re running a patched version of macOS on an unsupported machine using OCLP (OpenCore Legacy Patcher), your Wi-Fi card might not support the specific "Continuity" features required for modern AirDrop.
Check your System Report. Hold the Option key, click the Apple logo, go to System Information, and look under Wi-Fi for "AirDrop: Supported." If it says no, you’re looking at a hardware limitation, not a software bug.
iCloud Account Conflicts
If you recently changed your Apple ID password, your MacBook might be in a "partially logged in" state. It happens. It’ll ask for your password in System Settings, but you might have ignored the notification.

When your Apple ID isn't fully authenticated, the "Contacts Only" AirDrop mode fails because the Mac can't verify that the sender is actually in your contact list. Sign out of iCloud and sign back in if you’re desperate. It’s a pain, but it clears the certificate cache that AirDrop relies on for secure transfers.
Actionable Steps to Fix AirDrop Right Now
Don't just keep clicking the share button. Follow this specific sequence to reset the handshake between your devices:
- Toggle the "Everyone" visibility on the MacBook. Do not stay on "Contacts Only" while troubleshooting.
- Turn off Personal Hotspot on your iPhone. AirDrop and Hotspot use the same Wi-Fi hardware and they cannot run simultaneously. This is the #1 reason for "Failed" messages.
- Reset the
sharingdprocess using the Terminal commandkillall sharingd. - Check for VPNs. If you have a VPN active on your Mac (like NordVPN or a corporate Cisco AnyConnect), it may be rerouting all traffic and killing the local "Ad-Hoc" network AirDrop tries to build. Disable the VPN entirely.
- Check the "Screen Time" restrictions. Go to System Settings > Screen Time > Content & Privacy > App Restrictions. Ensure AirDrop isn't accidentally disabled here. It happens more often than you'd think, especially on managed work laptops.
- Physical proximity. Ensure the devices are within 30 feet, but ideally right next to each other. Distance matters for the Bluetooth discovery phase.
- Reboot both. If the
killallcommand didn't work, a full cold boot clears the NVRAM/PRAM (on Intel Macs) or resets the hardware controllers (on Apple Silicon) that manage the wireless radios.
If you’ve done all this and it still fails, check the file name. Sometimes macOS rejects files with "illegal" characters or names that are too long if they are coming from a non-Apple source or a third-party app. Keep the file name simple—just letters and numbers—and try again. Usually, it's the simple things that trip up the most advanced software.
