Safari 11.1
Jul 10, 2018 Available for: OS X El Capitan 10.11.6, macOS Sierra 10.12.6, and macOS High Sierra 10.13.6 Impact: Processing maliciously crafted web content may lead to an unexpected Safari crash Description: A memory corruption issue was addressed with improved memory handling. CVE-2018-4270: found by OSS-Fuzz WebKit. Sep 18, 2017 Hmm. I just checked this - iOS 11 (iPhone 6) and El Capitan 10.11.6. IPhone sees Safari tabs from the Mac, but the Mac doesn't see anything from the iPhone. Tested on 2 different Macs running El Capitan. Also tested on an iPad with iOS 10.3.3 - same as the Macs. Also just fired up a virtual machine running Sierra 10.12.6. I recently upgraded from 10.10 Yosemite to 10.11 El Capitan. I'm now on 10.11.6 and have installed all available updates in the app store. However, my Safari version is still 9.1.3. Safari 10 and 11 are compatible with El Capitan - but the app store doesn't push them to me, and I can't find a direct download link after alot of searching around. Jun 11, 2018 So I re-installed El Capitan (10.11.6) and now seem to have Safari v11. Was hoping to find a stand alone download link for Safari v10 or 11 but such seems elusive.
