I have a Mid-2011 MacBook Air. Everything seems to be working fine, except Safari keeps freezing and stops responding. Sometimes, when Safari freezes, it causes the whole computer to crash and I have to restart it.

I thought browsers were supposed to have security measures that prevent this from happening (like Sandboxing). How can a webpage crash the whole OS?

  • can you provide the url of a page which causes this problem? do you have the same problem with FireFox or Chrome? – Tom Gewecke Jan 31 '16 at 0:49
  • Do @TomGewecke suggestion first. Subsequently, open your Console.app, located in /Appications/Utilities/Console. Update the original post with the contents of your most recent com.apple.safari… or com.apple.webkit…. log under “System Diagnostic Reports” – njboot Jan 31 '16 at 1:05
  • I figured out the answer. It was because of Flash. – clickbait Aug 22 '16 at 0:33

My assumption solution: Safari is continuously attempting to reload the last session. To resolve this issue go to ~/Library/Saved Application State/ Remove the com.safari... folder and place in the Trash.

A second issue could be adware, which created the issue in the first place. Open Safari, which should operate properly after removing the above folder, and go to AdwareMedic . Download and run the free program and that will remove any adware.
