macOS AirPlay error code 3145 means your Mac cannot detect or connect to an AirPlay receiver — such as an Apple TV, HomePod, or AirPlay 2-compatible smart TV — on your network. This is typically caused by a network mismatch, a firewall blocking AirPlay traffic, or a software glitch on either the sending Mac or the receiving device. In most cases, the fix is straightforward and does not require any special tools or technical expertise.

Tools You'll Need

How to Fix Error Code 3145

  1. Confirm Both Devices Are on the Same Wi-Fi Network

  2. Restart Your Wi-Fi Router and All Devices

    Restarting your router will briefly disconnect all devices in your home from the internet. Let others in your household know before doing this.

  3. Enable AirPlay Receiver Settings on the Target Device

  4. Check macOS Firewall Settings

    Only disable your firewall temporarily for testing. Re-enable it once troubleshooting is complete to keep your Mac secure.

  5. Update macOS and Receiver Firmware

    Back up your Mac using Time Machine before installing a major macOS update to avoid data loss if something goes wrong.

  6. Flush the DNS Cache and Renew Network Settings on Your Mac

  7. Sign Out and Back Into iCloud / Apple ID

  8. Reset Network Settings as a Last Resort

    This step removes saved Wi-Fi passwords and network configurations. Make sure you have your Wi-Fi password available before proceeding.

When to Call a Professional

If you have completed all eight steps and AirPlay error 3145 persists, the issue may be related to a hardware fault in your network adapter, a corrupted macOS installation, or a defective AirPlay receiver. At this point, contact Apple Support at support.apple.com or visit an Apple Store or Apple Authorized Service Provider. If the problem is specific to a third-party AirPlay-compatible TV, contact that manufacturer's support line. Additionally, if your home network uses enterprise-grade equipment, complex VLANs, or managed switches, consult your network administrator — AirPlay's Bonjour protocol can be blocked by certain network configurations that require professional configuration.

Frequently Asked Questions

Why does macOS AirPlay error 3145 keep coming back after I fix it?
Recurring error 3145 is usually caused by a persistent network issue, such as your router assigning different IP addresses to your devices (DHCP conflicts), or a firewall or security app repeatedly blocking Bonjour discovery traffic. Try assigning a static IP address to your AirPlay receiver in your router's admin settings, and make sure no third-party security software is blocking mDNS or Bonjour traffic. Keeping all devices and software up to date also reduces recurrence.
Does AirPlay error 3145 affect AirPlay audio as well as video?
Yes. Error 3145 indicates your Mac cannot find any AirPlay receiver at all, which affects both audio and video streaming. Whether you are trying to mirror your screen to an Apple TV or stream music to a HomePod, the same network discovery process is used. Fixing the underlying network or software issue will restore both audio and video AirPlay functionality.
Can I use AirPlay without Wi-Fi to avoid error 3145?
Yes, in limited scenarios. If your Mac and Apple TV or HomePod support Bluetooth, they can sometimes establish AirPlay connections without a shared Wi-Fi network using peer-to-peer AirPlay (available on Apple TV 3rd generation or later and recent Macs). However, this only works between Apple devices and is not available for third-party AirPlay receivers. To enable it, make sure both Bluetooth and Wi-Fi are turned on even if they are not connected to the same network.
Will a VPN on my Mac cause AirPlay error 3145?
Yes, a VPN running on your Mac can cause error 3145. VPNs route your network traffic through a remote server and can prevent your Mac from seeing local network devices like Apple TV or HomePod. Disconnect from your VPN before using AirPlay. If you need to keep the VPN active, check if your VPN client has a 'split tunneling' or 'local network access' option that allows local device discovery while the VPN is running.
Does macOS AirPlay error 3145 mean my Apple TV is broken?
Not necessarily. Error 3145 most commonly points to a network or software configuration problem rather than a hardware failure. Your Apple TV is likely fine — it just cannot be found by your Mac at that moment. Work through the steps above, starting with verifying that both devices are on the same Wi-Fi network. If your Apple TV works normally for other functions (playing apps, streaming services) but still does not show up for AirPlay, the issue is almost certainly on the network or Mac software side, not the hardware.
