Safari makes os freeze I have a Mid-2014 MBP retina 15" running OSX 10.11.5. It runs flawlessly except for occasional Safari freezes. It happens only while I'm using Safari, and mostly when I try to close a tab. I've contacted Apple support multiple times, and they advised me to try a few things, none of which worked. I've tried to following:


cleared history
deleted cashes in ~/Library/caches and /Library/caches/


When it freezes, everything freezes with absolutely no response, so I have to do a hard reset every time. What could be the problem? How can I diagnose the problem and fix it?
You can try the following:

In Preferences (cmnd+,)

Privacy:


Check: Allow from websites I visit.
Remove all website data..
Prompt for each website one time only
Ask websites not to track me


Notifications:

Remove all

Extensions:

Disable them all for now.

Search:

Untick all and only tick: Enable quick website search



Quit (cmnd+Q) and re-open the app. Let us know if it happens again? :)
