One of the most common reason that MacOS can't use VPN is because you didn't allow our App to use VPN system extension.

If you encounter this issue, please delete the app and reinstall it. During installation, carefully read the prompt message and click on "Open Security Preference", "Allow" or similar action.

These are the installation steps:

1. During installation, System will prompt two popups.

The first one: "ChamVPN" would like to add VPN Configurations, click on "Allow"; The second one: "System Extension Blocked", click on "Open Security Preferences".

2. Upon click on "Open Security Preference", you will be landed on "Security & Privacy" page.

You need to: click on "Lock" icon on the bottom left corner to start making changes; If you see a System Preferences prompt, click on "Use Password" or use Touch ID to allow it.

3. Click on "Allow" near the bottom right corner (After you click on Lock icon, allow becomes clickable)

The web version of the apps, e.g. Telegram, WhatsApp or Gmail, are using HTTPS, which is supported by split mode. The split mode can only change the routing mode for HTTP (port 80) and HTTPS (port 443). That is why you can access the web version.

For the app version, they might have used any ports. Hence you will need to do one of these steps:

• Use "Global Mode" in routing settings
• Change the proxy settings of the app, below is an example of changing proxy settings for LINE:
  
  

• While you try to login on a new device, if the device limit has been reached, you will get redirected to the "Unbind Device" page, from there you can unbind the devices
• Or, you can go to "Menu" -> "App Settings" -> "Device List", click on the device to unbind it.

We have found that, some users don't know which server to use after deciding which region to use.

To make it easier for you, we decide to show region only. ChamVPN will automatically select the best performance server within your selected region for you. These are the details:

• Location list only shows the regions. Under the hood, there are hundreds of servers within each region. Upon selecting a region, ChamVPN will connect you with the best performance server according to your network condition.
• If you don't like the connected server, you can always disconnect and re-connect to the same region, you will be connected to a different server.
• You can repeat above step until you are satisfied.

There are several common reasons:

• Slow local internet (without VPN on)
• Certain VPN server location has busy traffic

To troubleshoot the network issues, please follow the steps:

• Check your local network speed by disconnect the VPN;
• While keeping VPN disconnected, switch between WIFI, 4G, 5G to find the troubleshoot your network. E.g. if your wifi has poor connectivity, switch to your cellular 4G/5G.
• Disconnect VPN, switch to another region, and connect;
• If you like to stay in the same region, try disconnect and reconnect to the same region. Even you are selecting the same region, there are actually hundreds of servers behind a single region. Every time you connect, we will relocate a different server for you.
• You can repeat above steps until you find the best server for you.

Global Mode: Access everything with VPN. This might slow down some local websites & apps traffic.

Split Mode: Only use VPN when accessing common GEO blocked (China firewall blocked) websites, e.g. Google, Youtube, Netflix etc. When accessing Chinese websites, use local network without VPN.

You can change the routing mode under App Settings.

If you found certain websites or apps can't be accessed, please change your routing mode settings to "Global Mode".

Although there are free VPNs and proxy services, they are not recommended as they do not offer the same privacy and security benefits of a paid VPN. Many do not work as advertised, some may even sell your data, and most will leave your networks vulnerable to attack.

Our VPN security app provides an additional layer of security between your Mac and the internet so you can browse, shop, and stream content privately and securely. In addition to shielding your identity from online snooping or data mining, a VPN also unblocks websites and content that may not be readily available in your region due to censorship or firewalls from your school or office network.

While macOS provides the option to connect to a VPN server in System Preferences, it is technically not a VPN service. It is actually a conduit that connects to third-party VPN services like ChamVPN.

It’s easy! Simply choose a plan, download the ChamVPN app from the App Store, open the app, and press the “On” button. Your connection is now encrypted.
