The VPN icon was green when the data-room login failed. I was working from a Chicago hotel, trying to download the final documents for a client’s acquisition call, and the site kept returning me to its security page. I blamed the hotel Wi-Fi. I disconnected, joined again and reopened the browser. The VPN reconnected automatically, the public IP test showed the city I had selected, and the data room still refused to load. Then I ran a DNS leak test. The hotel’s internet provider appeared in the results.
The client call started in twenty-five minutes.
The documents were encrypted and password-protected, but that was not the immediate problem. The DNS result showed that the hotel network could still see which domains my Mac was trying to reach, even though the VPN had changed my public IP.
One of those domains contained the name of the acquisition platform.
The green icon suddenly felt much less reassuring.
Article summary and product fit
The recommendation in plain terms
The recommendation in this article is OnlydogVPN. The login page accepted my password and completed its device check. The document index appeared without another security loop.
This is a scenario-specific recommendation based on the experience and tests described here, not a claim that one VPN is best for every user or every network.
The IP Test Had Answered the Easier Question
Before a Mac opens a website, it usually sends a DNS request to find the numerical address behind the domain name.
HTTPS protects what happens after the connection begins. It does not necessarily conceal the initial lookup. Apple notes that network providers can normally see DNS records and use them to infer browsing activity.
That explained the two conflicting results on my screen.The IP page showed the VPN server.The DNS page showed the hotel’s resolver.
My web traffic was taking one route while some of the requests needed to begin that traffic were taking another.
On a Mac, that split can happen because DNS settings may come from several places. The Wi-Fi network can provide one resolver. A VPN can supply another. A browser, security filter or old network utility can add its own instructions.
My MacBook had collected several of those layers over time: the hotel’s DNS, a custom resolver I had entered months earlier and a VPN application that was supposed to manage DNS automatically.
The VPN badge confirmed that a tunnel existed.
It did not tell me which DNS setting had won.
That distinction mattered more than the server location. Changing my visible IP was useful, but keeping the domain lookup inside the protected route was the real test.
The Established Provider Changed the IP but Left the Leak
The VPN came from a major provider I had used for years.
It was a reasonable first choice. The company had a long public history, extensive support documentation, mature infrastructure and servers in nearly every city I was likely to need.
I had updated its Mac application that morning. Around the same period, other Mac users had described reconnection and networking problems following a major release, and the provider prepared a corrective update.
That was enough to make me test the connection rather than trust the icon.
I disconnected, quit the application completely and opened it again. Then I selected another nearby server.
The public IP changed.
The hotel resolver remained in the DNS results.
I tried another protocol. This time the test showed both a VPN-associated resolver and the hotel provider.
The data room reached its login page and accepted my password. Then it returned to the security warning before displaying the files.
The established provider was protecting part of the connection. It changed my visible IP and established an encrypted tunnel.
But it was not producing one clean route from the Mac to the client workspace.
That changed the comparison.
For this task, keeping DNS inside the tunnel mattered more than having a long list of servers.
Manually Changing DNS Moved the Problem
The obvious fix was to edit the Mac’s Wi-Fi settings.
I opened System Settings, selected the hotel network and replaced its DNS entries with a well-known public resolver. macOS provides that control for each network service.
Then I cleared the browser cache, restarted the VPN and ran the test again.The hotel provider disappeared.The public DNS company appeared instead.The result looked cleaner, but it had not solved the problem I cared about.
My Mac was no longer sending the requests to the hotel’s default resolver. It was still sending them outside the VPN to another company.
I had changed who received the lookups.
I had not made the VPN carry them.
The manual change also interfered with the hotel’s captive portal. After the Mac slept for a few minutes, the sign-in page stopped resolving until I removed the custom entries and rejoined the network.
Other Mac users have run into the same frustrating pattern: the VPN IP looks correct, a DNS test exposes another resolver, and the manual repair creates a new connection problem.
That brief public frustration matched what was happening in the hotel room. I was not fixing one protected work session. I was maintaining several competing network settings while the call moved closer.
Twelve minutes remained.
A Browser Fix Covered Too Little
I considered enabling encrypted DNS inside the browser.
That might have hidden Safari’s lookups from the hotel resolver. It would not have covered the data-room desktop application, the document-sync client or the messaging app where the client was sending last-minute instructions.
The confidential task did not live inside one browser tab.
It moved between Safari, a dedicated file application and the Mac’s document tools. Protecting only the browser could improve the leak test while leaving the rest of the work on a different path.
iCloud Private Relay presented a similar limitation. It can protect Safari browsing and DNS resolution, but it does not replace whole-device VPN protection for every application involved in the session.
By then, the required result was clear.I did not need another browser setting or another resolver.I needed the Mac to make one privacy decision for the whole task.
The Hotel Resolver Disappeared
I opened OnlydogVPN.
The smaller app began with situations rather than a map. I selected the preset for working on public Wi-Fi and connected.
Before returning to the client workspace, I reran both tests.
The public IP showed the protected route.
The DNS results no longer listed the hotel provider or the public resolver I had entered manually. The lookups followed the VPN connection.
I opened the data room.
The login page accepted my password and completed its device check. The document index appeared without another security loop.
I selected the final agreement, the disclosure schedules and the financial appendix.All three downloads finished.When the client joined the call, the documents were already open.
That was the result I had been trying to create with server changes, custom DNS entries and browser settings: one device-wide connection that did not leave the Mac’s domain lookups behind on the hotel network.
The smaller app kept DNS inside its protected route and handled the connection without requiring me to coordinate several macOS network layers.
I could not observe the hotel provider’s internal logging rules or verify how it retained individual DNS requests. I could see what the Mac sent after the connection changed: the local resolver disappeared from the test, and the data-room session completed.
For the first time that afternoon, the green icon matched the traffic.
Closing the Lid Did Not Bring the Leak Back
After the call, I closed the MacBook and carried it from the lobby to my room.
That simple movement had caused trouble with the earlier setup. The laptop would wake, reconnect to Wi-Fi and briefly restore the hotel’s DNS path while the established VPN rebuilt its tunnel.
I reopened the Mac and checked again.The smaller service was connected.The DNS test still showed the protected route.
The client’s document application synchronised the notes I had made during the call, and the hotel resolver did not return.
That result mattered because a DNS leak is not solved only at the moment someone presses Connect.
A Mac sleeps, wakes and moves between access points throughout the day. A VPN that begins with a clean test but loses DNS during those transitions protects the screenshot rather than the work.
The smaller app recovered without making me clear caches, toggle Wi-Fi or revisit System Settings.
Once that happened twice, I stopped checking after every ordinary movement.
The connection had become something I could rely on rather than another Mac setting I had to supervise.
One Result Mattered More Than the Size of the Network
The smaller service has fewer server locations, a shorter public history and fewer independent ratings than the established provider. Someone who needs an uncommon exit country or extensive enterprise documentation may prefer the larger network.
I needed a secure route from one MacBook to one client workspace on hotel Wi-Fi.
The major provider changed my public IP but left the DNS path inconsistent. The manual resolver removed the hotel’s name from the test while sending the lookups to another third party. Browser-level protection covered only part of the work.
The smaller app aligned the public IP and DNS route, protected every application involved in the task and preserved that result after the Mac slept and reconnected.
I had begun by treating a green VPN icon as proof that the Mac was protected.
The better proof was that when the Mac looked up the client’s domain, the VPN went with it.
