Viscosity 1.12 is now available for macOS! This is a big update, with new web authentication features, expanded SAML support, improved support for macOS 26 (Tahoe), proxy support improvements, behind-the-scenes upgrades and enhancements, and many other new features and bug fixes.

Viscosity now supports web authentication using the default web browser. This enables existing browser-based sessions to be used when authenticating, saving the need to authenticate again when the same session can be used for VPN authentication. Browser extensions, scripts, and autofill will also work without the need to set up a macOS "associated domain".

We've also expanded Viscosity's SAML authentication support to work with two custom implementations: Amazon's AWS Client VPN SAML authentication and WatchGuard's Mobile VPN SAML authentication. Simply import an AWS Client VPN configuration into Viscosity, or use the Import from Server feature with a WatchGuard VPN server, and connect the new VPN connection to get started.

This update also improves support for macOS 26 (Tahoe), with user interface updates to adopt the Liquid Glass design and UI icon styles, as well as under-the-hood improvements for better networking support.

Version 1.12 also includes a lot of other new features, improvements, and bug fixes. Be sure to check out the release notes below.

Finally, this update removes support for macOS 12 (Monterey). Users are strongly encouraged to update to macOS 13 or later. Older Viscosity releases can still be found at the Legacy Downloads page if required.

Version 1.12 will also be available for Windows in the coming weeks. If you'd like to try out some of the new features before the full release, you can subscribe to beta updates for Viscosity, which provide early access to the latest features.
