Adding my voice to the complaints, plus some remarks :
- Retina MBP mid-2012
- On 10.11.2 although the same problem occurred on Yosemite. However I fixed it. I just can't remember how, and I lost my configuration files when I foolishly clean wiped my hard drive.
- I'm also quite confident that this is (at least partly) a router issue. The router lent by my previous ISP worked flawlessly with Safari/Google search. The issue started with this new crappy router (Dlink DIR-825). My friend had the same router with the same problem, and buying an Airport express did solve the problem for him.
- And just like every one here I did fiddle with most of the configuration parameters : from disabling ipv6, changing dns servers, disabling prefetching, changing router-side configuration, etc. all of them to no avail. Console hasn't shown anything of value (I have been tracking `Safari' and `DNS'). The problem only occurs on Google owned domains, no problem with Yahoo / Duckduckgo / Bing (but all of them are crappy compared to google 😮).
- Finally although it works fine with Chrome on Mac OS, Safari on my iphone5 also works well with the same wifi, so maybe webkit is not to be blamed. However, I really can't tell which subtle differences there are between both softwares.
- Bottom line : one h3ll of a bug
