First, distinguish between “the app won’t open” and “the app opens but can’t connect.” For launch issues, check the installer architecture and macOS security alert. For connection issues, check the core, local port, system proxy, and server connection in order. Start with the system proxy for web browsing; authorize TUN as an administrator only if you need to route traffic from more apps. There’s no need to enable every permission at once.
First, know the difference: a blocked launch isn’t a network problem
“Unable to verify developer” is usually a macOS app security check. It appears before the main window opens and has nothing to do with whether your subscription is valid or the server is online. Refreshing your subscription or changing the server port won’t clear a launch block.
Start by choosing Apple menu → “About This Mac.” If it shows Apple silicon, choose the arm64 installer; if it shows an Intel processor, choose the x64 installer. Some x64 apps on Apple silicon may require Rosetta, but using the matching architecture is the best way to reduce variables while troubleshooting.
| What you see | Where the issue is | What to do first |
|---|---|---|
| “Unable to verify developer” or “Apple cannot check it for malicious software” | App launch security check | Verify the source, then check the blocked-app entry in “Privacy & Security.” |
| “The app is damaged and can’t be opened” | Download integrity, signing, or app bundle status | Download the installer for the correct architecture again; don’t apply the standard allow-app steps. |
| “Will damage your computer” or “malware detected” | Explicit security risk alert | Stop and verify the source. Don’t force the app to open. |
| The window opens, but websites won’t load | Core, proxy entry point, or remote connection | Check the logs, then verify the local listener and system proxy. |
Allow the app in “Privacy & Security”
These steps apply to macOS 13 and later, which use System Settings. Button labels may vary slightly between versions, but the option is in the Security section of “Privacy & Security.” Allowing the app applies only to this app from a source you’ve verified; it doesn’t disable security checks for your Mac.
-
Move the app to Applications
Open the downloaded DMG and drag v2rayN into Applications. After ejecting the disk image, launch it from Finder → Applications rather than continuing to run the copy inside the installer.
-
Trigger the launch alert
Double-click v2rayN, read the macOS alert, then close it. Note the exact wording and make sure it’s a developer verification warning—not an explicit malware alert.
-
Find the blocked-app entry
Open Apple menu → System Settings → “Privacy & Security,” then scroll to “Security.” Look for the recent entry showing that macOS blocked v2rayN from opening.
-
Allow this launch
Click “Open Anyway” and authenticate with Touch ID or administrator credentials when prompted. If another confirmation appears, verify the app name and click “Open.”
-
Verify the app launches again
Make sure the main window opens, then quit and launch the app once more from Applications. If macOS blocks it again, first check whether you’re opening another copy from Downloads.
macOS 15 and later apply stricter launch checks to some apps that aren’t properly signed or notarized. Don’t assume the right-click “Open” shortcut from older guides will work. Avoid commands that remove quarantine attributes, disable Gatekeeper, or change permissions across the whole app directory; they can hide the original cause and make troubleshooting harder.
System proxy or TUN: start with what you need
v2rayN is the configuration and management interface; the core handles traffic forwarding. The interface can launch without the core running, and the core can connect to a server without your browser using the proxy. The system proxy tells apps that follow system settings which local endpoint to use. TUN routes traffic that matches its rules through a virtual network interface.
Start with the system proxy
RecommendedLeave TUN off, select a working server, then enable “System Proxy” → “Set system proxy” in v2rayN. Menu locations may vary by desktop version; look near the bottom of the main window or in the tray menu.
Best for: browser traffic, initial setup, and separating local proxy issues from remote connection problems.
Enable TUN only if needed
Try TUN only after confirming that the regular proxy works. Creating a virtual interface, changing routes, and related operations usually require administrator authorization. The exact prompt depends on the client version and core in use.
Best for: apps that don’t follow the system proxy and scenarios where you need to route traffic centrally.
After enabling the system proxy, check System Settings → Network → your active Wi-Fi or Ethernet connection → Details → Proxies. The Web Proxy, Secure Web Proxy, or SOCKS Proxy entry should match the inbound type the client actually provides. A checked box alone doesn’t mean the settings are correct.
- Address: The local proxy usually points to
127.0.0.1. Don’t enter your subscription server address in the local proxy field. - Port: Use the local listening port shown in v2rayN under Settings → Parameters. Tabs and field names may differ between versions.
- Authentication: Enter credentials in the system proxy settings only if the local inbound explicitly requires a username and password.
- Before quitting: Select “System Proxy” → “Clear system proxy” before closing the client, so macOS won’t keep pointing to a port that’s no longer listening.
Network permissions: grant access when prompted, not across the board
macOS doesn’t have a universal “allow all network access” switch for desktop apps. App security approval, local network access, system proxy changes, and TUN elevation are separate steps. One prompt doesn’t mean the others are taken care of.
| Permission or setting | What it does | When and how to use it |
|---|---|---|
| Local Network | On macOS 15 and later, controls local network access covered by this permission. | If the app needs to reach your router or other local devices, or provide a service to your LAN, check System Settings → “Privacy & Security” → “Local Network.” |
| Network proxy settings | Changes the proxy address and port used by the current network service. | If macOS requests authentication, verify what’s requesting the change before approving. If it fails, check the active network service and any management policies. |
| TUN administrator authorization | Allows restricted operations such as creating a virtual interface and changing routes. | Follow the authorization flow shown by your client. Don’t run the regular graphical interface as an administrator all the time. |
| Incoming firewall connections | Controls whether other devices can connect to services on your Mac. | A local app accessing its proxy over a loopback address usually doesn’t need external incoming connections enabled. |
If v2rayN doesn’t appear in the “Local Network” list, that doesn’t necessarily mean the installation is broken. This permission often appears only after the app attempts a controlled access. Accessing the public internet or a loopback address doesn’t automatically require local network permission. Don’t turn off the entire firewall to fix a web timeout.
Check the connection path with the local port
Troubleshoot in this order: core startup → local listener → explicit proxy request → system proxy → TUN. The 10808 below is an example port, not a default for every version. Use the sample commands only if your client actually provides an HTTP or mixed proxy inbound on that port.
Open Finder → Applications → Utilities → Terminal, then run these two read-only commands. The first checks for a TCP listener on the example port; the second reads the current system proxy settings. Neither command changes your system settings.
lsof -nP -iTCP:10808 -sTCP:LISTEN
scutil --proxy- No output from the listener check: First verify the actual port and check the core logs. No output alone doesn’t prove the app failed to install.
- The listener isn’t the expected core: Another process may be using the port. Note its name, choose an unused port in the client, and restart the core.
- The system proxy address or port doesn’t match: Reapply the system proxy and check which Wi-Fi or Ethernet service is active.
Once you’ve confirmed that this endpoint supports HTTP proxying, send an explicit proxy request. This test doesn’t depend on whether your browser uses the system proxy, so you can check local forwarding separately from system-wide proxy settings.
curl --connect-timeout 10 --max-time 20 -I \
--proxy http://127.0.0.1:10808 https://v2raybit.com/If the local endpoint supports SOCKS only, change the proxy argument to --proxy socks5h://127.0.0.1:10808. Use the port where the SOCKS listener is actually running. The response will vary: a refused connection usually points to the local listener, while a timeout may indicate a remote connection, DNS, or routing rule issue. Check the core logs to narrow it down.
Common questions and restoring your settings
Do I need to click “Open Anyway” every time I launch the app?
You usually don’t need to repeat the approval for the same app copy. Quit all copies, then launch it from Applications. An update that changes the app bundle may trigger another check. If macOS keeps blocking it, note the exact alert and check whether you’re running an older copy or your Mac is subject to a management policy.
I allowed the app to open. Why is my subscription still failing to update?
Allowing the app only clears the launch check. Verify that the subscription URL is complete and hasn’t expired, and check whether the update needs a proxy. “Update through proxy” can help reach the subscription only if a working proxy path already exists; it can’t create a connection on its own. Hide the full subscription URL and any credentials before sharing logs.
TUN disconnects my internet as soon as I turn it on. What permissions should I add?
Turn TUN off first and return to the system proxy path you’ve already verified. Then enable TUN on its own and note the first relevant error in the logs and any macOS authorization prompt. If the regular proxy works but TUN doesn’t, focus on the virtual interface, route conflicts, and DNS. Don’t change the server, protocol, and permissions all at once.
What should I do if my Mac loses internet access after I quit v2rayN?
Go to System Settings → Network → your active connection → Details → Proxies and check whether the proxy still points to a local port. Remove only the proxy entries set by the client; keep any existing work network settings. If TUN is enabled, turn it off normally before quitting, and reconnect to your current network if needed.
Keep three details handy for further troubleshooting: your macOS version and chip type, the exact v2rayN version, and the first relevant log entry from the failure. Identify which layer is failing before changing its settings. This usually gives you a clearer answer than repeated reinstalls or granting broader permissions.
