Air VPN (app)

Field Report — Air VPN (app) on macOS

Machine: MacBook Air M2
System: macOS Ventura 13.5.2
Source: OrchardKit build

Hey, so I spent yesterday digging into Air VPN (app) from OrchardKit, and it was one of those sessions where you think “this will be quick” and then… well, not so quick. I just wanted to set up a VPN connection, test a few servers, and make sure my traffic was actually routing correctly. Pretty standard.

First step: downloaded the .dmg from OrchardKit, dragged the app into /Applications, double-clicked… and macOS Gatekeeper hit me with:

“Air VPN can’t be opened because Apple cannot check it for malicious software.”

Right-click → Open → Confirm. The UI launched, but the first server connection attempt failed immediately. No error dialog — just a spinning wheel that never stopped.

My first thought: corrupted installation. I uninstalled, re-downloaded, reinstalled. Same behavior.

Next, I suspected a network permissions issue. VPN apps need full network access and, on macOS Ventura, also require specific entitlements to configure system-level tunnels. I checked System Settings → Privacy & Security → Network. The app wasn’t listed, which explained the silent failure.

I tried granting Full Disk Access (yes, a bit of overkill), thinking maybe some config files weren’t writable. Connection still didn’t work — the app kept failing silently.

Then I remembered the quarantine flag. Any app downloaded from the web carries com.apple.quarantine, which can block helper binaries or launch daemons needed for VPN tunneling. Running:

sudo xattr -cr /Applications/Air\ VPN.app

made a difference. Relaunching the app triggered proper permission prompts. I granted only the network-related access it requested. Suddenly, the VPN connected, status lights turned green, and all test traffic was routing correctly.

I saved/bookmarked this page because it clarified macOS handling of unsigned VPN utilities — my notes here:

Attempts that didn’t work:

Reinstalling the app — did nothing.
Granting Full Disk Access — unnecessary for network tunneling.
Tweaking system firewall manually — no effect.

What actually worked: clearing quarantine attributes, then approving the network permissions the app requested. Connection stable, speeds normal, CPU usage around 12–15% during active transfer, memory ~300–400MB. On M2, the app feels light and responsive.

Quick checklist for next time:

Move the app to /Applications before first launch
Right-click → Open → bypass Gatekeeper warning
Clear quarantine attributes with xattr -cr
Launch and approve only the permissions requested

Apple references: Gatekeeper & notarization docs: https://developer.apple.com/documentation/security/notarizing_macos_software_before_distribution, network permissions: https://support.apple.com/guide/mac-help/control-network-access-on-mac-mchlp2593/mac, and App Store search for similar VPN clients: https://apps.apple.com/search?term=vpn

Lesson learned: a VPN app may appear broken on first launch, but macOS security (quarantine + network entitlements) is usually the culprit. Once you handle those, the app works exactly as intended, without over-permission hacks.
