ProtonVPN users on older Macs must upgrade systems or switch protocols to keep using the service, as older macOS versions and protocols are being phased out.
ProtonVPN updates macOS requirements
ProtonVPN, a Swiss-based virtual private network (VPN) service, has announced that users of older macOS versions will need to update their systems or configurations to continue using the service starting January 5. Older macOS versions no longer supported
The company will stop supporting macOS versions prior to Sonoma (14), including Big Sur, Monterey, and Ventura. This means users on these operating systems will need to upgrade to macOS Sonoma or newer to use the official ProtonVPN client. Security concerns drive the change
ProtonVPN cited security reasons for the update, noting that older macOS versions no longer receive regular updates and may pose risks to users. The company aims to ensure continued security and functionality for its service. Discontinuation of older OpenVPN configurations
In addition to the macOS update, ProtonVPN will stop supporting older OpenVPN configurations by the end of February. Users will need to update their configurations to continue using the service effectively. Switching from IKEv2 to other protocols
ProtonVPN is also phasing out the IKEv2 protocol, which encrypts data between a user’s device and the company’s servers. Users who have selected IKEv2 manually will need to switch to WireGuard or Stealth protocols instead. Alternatives for older Macs
For users whose Macs cannot run macOS Sonoma, ProtonVPN offers manual configuration options using third-party clients like WireGuard or OpenVPN. These methods require more technical steps but allow continued use of the service without upgrading the operating system.
