There’s good news for Mac developers who have been curious about the new features in Safari 10, which will be released alongside macOS Sierra this fall, but haven’t wanted to install Sierra just to check it out. Apple has released a developer beta of Safari 10 that works on OS X Yosemite and El Capitan.
Safari 10 Beta
The Safari 10 beta for Yosemite and El Capitan can be downloaded from the Apple Developer Center. You do need to be a registered Apple developer to access the beta. While it doesn’t include all of the features available in the Safari 10 included in the macOS Sierra, notably, Apple Pay on the web, and Picture in Picture support, it does support the following new features:
- New Bookmarks sidebar, including double-click to focus in on a folder
- Redesigned Bookmarks and History views
- Site-specific zoom
- Improved AutoFill from your Contacts card
- Reader improvements
- HTML5 and legacy Plug-ins
- Allow reopening of recently closed tabs
- Back closing spawned tabs
- Improved ranking of Frequently Visited Sites
- Web Inspector Timelines Tab
- Debugging using Web Inspector
Under OS X El Capitan, the Safari 10 beta does support Safari Extensions and developing Safari App Extensions, so developers can get a jumpstart on creating extensions for the upcoming new macOS.
While Safari 10 is currently limited to developers, the new browser will be available to public beta testers as part of the macOS Sierra public beta test, due to kickoff in July.
