Apple Safari 9.1 for Mac could be downloaded from the developer's website when we last checked. We cannot confirm if there is a free download of this app available. The application lies within Internet & Network Tools, more precisely Browsers. We recommend checking the downloaded files with any free antivirus.
From the developer:
Note: The direct download link is currently unavailable, but will be added as soon as it's public. It is available in the OS X 10.11.4 release.
Apple Safari is Apple's web browser that comes with OS X Yosemite. Safari is faster and more energy efficient than other browsers, so sites are more responsive and your notebook battery lasts longer between charges. Built-in privacy features are stronger than ever.
You may want to check out more software for Mac, such as Safari Technology Preview, Apple Configurator or Apple Remote Desktop, which might be similar to Apple Safari.
