Turning on a VPN usually means every app on your Mac starts routing through it, from your browser to your email to that one game that really doesn’t need to be encrypted. Split tunneling changes that. It lets you decide which apps go through the VPN and which ones use your regular connection, and for a lot of Mac users, that control ends up mattering more than they expected.
What Split Tunneling Actually Does
Split tunneling splits your device’s traffic into two paths at once. Some apps route through the encrypted VPN tunnel, and everything else goes out over your normal internet connection, unencrypted and untouched by the VPN. You choose which apps land in which group, usually through a simple list in the VPN’s app settings.
This matters because not everything benefits from being routed through a VPN. A banking app might work better on your direct connection to avoid location-based security flags.
A local streaming device or smart home app on your network might stop working entirely if its traffic gets rerouted through a VPN server in another country. Split tunneling lets you keep the privacy benefits where you want them without breaking the things that don’t need it.
Why This Matters More on macOS Specifically
Mac users tend to run a mix of apps that behave differently depending on how they connect. Video calls, cloud backups, local network devices, and browser tabs are often open at the same time, and routing all of it through one VPN tunnel can slow things down or cause apps that rely on your real location to misbehave.
There’s also a technical wrinkle specific to macOS. Some VPN apps implement split tunneling in a way that isn’t fully compatible with how macOS handles network interfaces, and the result is a connection that freezes or drops entirely instead of just excluding the app you wanted excluded.
This isn’t a rare complaint. Anyone who’s spent time in Mac-focused VPN discussions has likely seen someone mention their VPN locking up the moment they tried to exclude a single app from the tunnel. It’s frustrating because the feature is supposed to add flexibility, not risk the whole connection.
What a Reliable Split Tunneling Setup Looks Like
A split tunneling feature that actually works on macOS should let you add or remove apps without restarting the VPN connection, apply changes instantly, and keep the rest of your traffic encrypted while the excluded apps run normally. PureVPN’s macOS app handles split tunneling this way, letting you pick specific apps to bypass the tunnel while everything else stays protected, without the freezing issue that shows up in some other clients.
This is also where the choice of VPN for Mac starts to matter beyond just picking whichever service has the most ads. A VPN that treats split tunneling as an afterthought tends to show it in small ways, like a settings menu buried three layers deep or a connection that needs to fully restart every time you add an app to the exclusion list. A VPN built with macOS in mind treats it as a core feature, since it directly affects how usable the VPN is day to day rather than just when you’re actively thinking about privacy.
Common Situations Where Split Tunneling Helps
Working from home with a hybrid setup is one of the clearest cases. You might need your work VPN client and internal tools routed through a secure tunnel while your personal browsing and streaming apps run normally, without one connection fighting the other for control of your traffic.
Gaming is another. Routing a game through a VPN server can add latency you don’t want, while your browser and other apps still benefit from staying protected. Split tunneling lets the game connect directly while everything else stays covered.
Local network access is a quieter but common reason too. If you’re trying to print to a local printer, cast to a TV, or access a NAS device while connected to a VPN, full tunneling can break that connection since your Mac is technically routing traffic through a server elsewhere. Excluding just that one app or process solves it without turning the VPN off entirely.
It’s also worth noting this isn’t an Apple-only consideration. If you manage a home lab, a NAS, or a secondary machine running Linux alongside your Mac, the same logic applies there.
A VPN for Linux setup benefits from split tunneling in the same way, letting local services and internal tools stay on your direct connection while everything else you’re running gets tunneled through the VPN, which matters if you’re mixing local network access with remote encrypted traffic on the same box.
Setting It Up Without the Guesswork
The general process is the same across most VPNs that support it well. You open the VPN app’s settings, find the split tunneling section, and either add apps you want to exclude from the tunnel or, in some cases, apps you want to specifically include, depending on how the VPN structures the feature. On PureVPN’s Mac app, this is a straightforward list you can edit at any time, and changes apply without needing to disconnect and reconnect the whole VPN.
A good way to confirm it’s working correctly is to check your IP address inside an excluded app versus inside the browser you’re tunneling. If the excluded app shows your real IP and the tunneled app shows the VPN server’s IP, split tunneling is behaving as expected.
The Bottom Line
Split tunneling isn’t a niche feature for advanced users, it’s a practical fix for the real friction that comes from running an entire Mac through one VPN tunnel. The difference between a VPN that implements it cleanly and one that doesn’t shows up in small, annoying ways, like a connection that freezes when you try to exclude an app, or a setup that forces an all-or-nothing choice you shouldn’t have to make. Done right, split tunneling gives you the privacy of a full VPN connection without sacrificing the local access and app-specific performance you actually need day to day.
