OneSpan Sign's dependencies are generally on the browser, not on lower-level components. All of the following requirements are subject to change. ### Operating Systems - Microsoft Windows 10, 11 (except external touch-screen devices) - Mac OS X ([current version](https://support.apple.com/en-ca/109033), and its predecessor) ### Browsers The following browsers are supported for use with the OneSpan UI. Browser support for viewing PDFs may differ. - Edge (latest stable version) Microsoft Edge in [IE mode](https://docs.microsoft.com/en-us/deployedge/edge-ie-mode) or IE Compatibility mode is no longer supported by the New User Experience (including the [Signer Experience](/v1/docs/using-the-signer-experience)). - Chrome (latest stable version) - Firefox (latest stable version) - Safari (latest stable version) For all browsers, cookies must be enabled. ### PDF Versions The supported PDF versions are: - 1.3 through 1.7 ### PDF Viewers Acrobat or similar software may be required to view and print PDF files. Occasionally, a PDF viewer may give results that differ from those of Adobe Reader. When that occurs, OneSpan considers the Adobe Reader results to be more definitive. **Note**: The same consideration applies when displaying a pdf in a browser outside a Onespan environment. When the rendering of a pdf through a browser is different than Adobe Reader, Onespan considers the rendering from Adobe Reader to be more definitive. ### Mobile Devices - iOS - Android If you experience any issues on your mobile device, please contact our [Support Team](https://www.onespan.com/support).
