Why VPNs Break After macOS 26 Tahoe

Apple has removed support for certain older encryption algorithms and shorter key lengths in macOS 26 Tahoe. VPN protocols that depend on the built-in macOS system importer, such as IKEv1, IKEv2, and L2TP/IPSec, may fail to connect. In addition, vendor VPN clients including FortiClient, SonicWall Global VPN Client, and Cisco Secure Client may not yet be fully compatible with macOS Tahoe, which can result in failed connections or incomplete support for certain protocols.

Which VPN Protocols Could Be Affected?

• IKEv1
• IKEv2
• L2TP/IPSec
• Fortinet SSL VPN (FortiClient)
• Cisco AnyConnect SSL VPN (Cisco Secure Client)

These issues are not limited to a single vendor. If you are using any of the above VPN protocols, you may experience failures after installing macOS Tahoe.

Common Error Symptoms

• Your VPN will not connect at all after the upgrade
• Connections fail without helpful error messages
• The VPN works on older macOS versions but no longer on macOS Tahoe
