Apple has released Safari 11 for macOS Sierra 10.12.6 and Mac OS X El Capitan 10.11.6. The update to Safari includes various security patches, bug fixes, and includes a handful of new features for the Mac web browser.

Perhaps the most noteworthy feature of Safari 11 is that it stops media from automatically playing audio on most websites, thereby helping to prevent the user from having to mute tabs and tracking down which tab is playing sound when unexpected audio starts playing on sites like Facebook or many news websites.

Mac users can find the Safari 11 software update available in the Mac App Store Updates tab. You must be on the most recent version of Sierra or El Capitan to find the software update available, if you’re running a prior release of either Mac OS version the update does not appear to be available.

The release notes for Safari 11 include a focus on the following features and changes:

  • Stop media with audio from automatically playing on most websites
  • Adds the ability to configure Reader, content blockers, page zoom, and auto-play settings on a per-website basis, or for all websites
  • Improves AutoFill accuracy from Contacts cards
  • Includes updated media controls for HTML video and audio
  • Enhances performance and efficiency

Safari 11 as a separate download is only available for Sierra and El Capitan. Safari 11 is included by default in macOS High Sierra 10.13, which is due for widespread public release for Mac users on September 25.

Separately, Apple has also released iOS 11 update for iPhone and iPad, along with tvOS 11 for Apple TV and watchOS 4 for Apple Watch.

    On the backend of my website there are buttons that have links that open (Chrome and Firefox) which will not open in Safari now. Any ideas?

  2. Karl W says:

    Oddly I did not have a ‘check’ in the box for Font size, my MSN homepage would not load either.

    For the heck of it, I checked the box, then un-checked it and my page loaded! LOL go figure!

    So even if your box is not checked and you have the load problem, check the box (mine defaulted to 11) then just un-check it for a possible fix, it worked for me.
    Thanks to msr:)

  3. Johnny B says:

    Thanks msr. for posting what worked for you. It worked for me too.

  4. Sherman says:

    Since upgrading to Safari 11.0 (on an early 2009 iMac), I am getting immediate crashes when keying information into security question boxes, for example, or EVEN entering my name in the box right above this text box. I am having to submit this on Chrome because of the problem. Maddening, and I don’t see it listed by anyone else.

  5. Mark says:

    Thank you msr that worked for me as soon as i unchecked it msn showed up great

    • msr says:

      I’m glad the solution for MSN worked for everyone. It was incredibly frustrating. After I found the fix and was squinting at the small font I discovered that the font size can be increased for your homepage by going to Safari -Settings for this website – zoom. The “never use font size smaller than xxx..” isn’t functioning properly so I’m not sure why it was left in Safari 11 to just cause problems.

  6. Colin says:

    I’m running Mac OS X El Capitan 10.11.6 but there’s no sign of the new Safari update in my Updates tab of App Store.

    I’m in SE Asia, perhaps it hasn’t been rolled over to us yet?

    Though I rarely use Safari, I much prefer Firefox, I’d still like to have the new update if possible.

  7. msr says:

    I solved the MSN issue, or rather someone else did and it worked for me.

    “I got msn to load going to safari preferences, advanced pane ,accessibility I always had checked never use font sizes smaller than (old eyes) I unchecked the box guess what. Don’t Know if it helps but the only one for me that wasn’t loading.Worked fine before updating yesterday. Working fine again.”

    Only problem now is I hope I can read it.
    I also had other issues such as all previous pages loading when Safari started up even though I had everything set to not do that.

  8. Bill says:

    I am running Safari 11.0 and all of a sudden I can’t get my homepage to open all the way. I get the header and an ad and the rest of the page is blank. What is the fix for this?

  9. Jerry Carter says:

    Same as other like to read MSN each day. part of the several news outlets I read for work.

  10. Julie says:

    MSN will not load since update to 11. What up?

  11. Maddie says:

    I updated Safari this morning & am running Sierra. Now Twitter is malfunctioning in that I can’t Like or Retweet, on Flickr I can’t choose other tabs, on forums like Affinity etc., I cannot “like” posts. There are similar glitches on other websites.

    I waited a few days to upgrade Safari & hadn’t read any complaints elsewhere. I wish I hadn’t & could go back to the previous version. I’ll certainly not be updating iTunes for a while.

    • Maddie says:

      Okay SOLVED! When I updated to 11, a couple of the settings in Preferences were changed. Apparently it was a cookies thing.

      After checking, unchecking tons of things Safari works again. Relieved.

  12. Karsten Jensen says:

    I miss the RSS FEED. Bring it back please.

  13. Donk says:

    Same problem as msr.
    MSN doesn’t load with Safari……
    MSN fine with Firefox

  14. msr says:

    Sorry for posting twice. The first one I posted last night didn’t appear until I posted the second one.

  15. msr says:

    MSN homepage won’t load after upgrade to Safari 11. All I get is the search bar, the line with links for Outlook. Skype, etc., and one ad. The page is blank under that. Multiple attempts to fix it have not worked. The other two home pages I have set load fine. MSN is fine in Firefox.

  16. msr says:

    I updated to Safari 11 with El Capitan. Now my MSN homepage won’t load nor can I type the address in a new tab and get it to load. All I get is the search bar, sign in, the next line with Outlook, Skype, etc. links, and an ad. There are no articles, weather, news, etc. I’ve tried every fix I could find and nothing works. It’s fine in Firefox. I wish I had waited until they fixed the bugs and i can’t revert back to the earlier version.

  17. JMC says:

    So does Youtube. At least live streams do.

    • nospam says:

      Live streams still play automatically for me.

      The biggest change for me is that safari is constantly crashing now for no reason

  18. LG says:

    CNN still plays automatically.

  19. David says:

    With this update, as well as the iOS 11, Apple got rid of Feeds, the built in RSS reader, found next to the Reading Pane. I loved this feature, something I used more than almost anything else on the iPhone & Mac!
