As it's been said, Safari now features unified the address and search fields. You can now use the one unified field to both input web addresses and search terms.
How can they not be seperate??? What is Apple thinking? The google sidebar was much more convienent than this new Safari 6 is.
Do you feel the separated fields were more convenient because you're just used to separate fields, or are there actual ways the unified search field behaves that's in fact less inconvenient? The fact that you now have one field that's capabale of performing two functions—and only one shortcut (APPLE+L) instead of two (APPLE+L and APPLE+OPTION+F) to remember— seems more convenient, yeah?
As for what was Apple thinking: Google's own Chrome browser operates the same way, with a unified address bar. They call it the OmniBox and it's a popular feature that was drawing a lot of people to switch from Safari to Chrome. Additionally, Apple's whole philosophy towards both hardware and UI design is to find ways to simplify and remove redundancies.
As far as keeping Google as my default browser, that no longer exists. I had to change my browser from Google to Yahoo. I feel as though Google has now been running slower than ever since this update, and I am highly dissapointed. What a shame, I used to use Google for everything. Sorry, Google, we're through!
So, in Safari's Preferences, under General, you've changed the Default Search Engine from Google to Yahoo and you feel that Yahoo is working faster as the default search in Safari? There's a lot of factors that can affect the speed of our search results, but the majority of them would be nothing Safari has to do with (if the internet connection where you're searching is slow, an issue with Google's servers at the time of your search). I'm trying search terms in Safari 6 with Google as the default, and it's all pretty snappy to me. Faster, even.
There does not seem to be a memory in the search/address bar the way there was before.
Navigate to the new unified Safari search bar. Clear the field. See the magnifying glass at the left of the field? Clicking that reveals a dropdown of search options, including your recent search history. You could also clear the search field then press the "Down" key to get the same dropdown menu.
And now the Tabs are spread right accross the bar, which means we can´t double click to open a new Tab.
You have to go to the little `+´ button on the right, which is a pain when you´re so used to the double Click!
There's a faster way to open a new tab—even faster than the double-click process you're used to: APPLE+T. Get used to that and you'll never use the mouse to open new tabs again.
If you really, really hate Safari 6: you can always download a previous version and install that. But remember, old versions of software don't just have different UI elements you might be more used to: they also will keep security vulnerabilities that may have been patched in newer versions.
In my opinion, it's not really worth it to stay set in your ways. Especially in this case, where no features have been discarded, just tweaked a bit.
