Yosemite is clearly first version fully optimized for Retina, potentially at expense of non-retina users. Every time I unlock my MacBook Pro I think "wow, this is gorgeous" (I have another one at work not updated to Yosemite, so I see difference every day). Unlike controversial iOS 7 update, Yosemite clearly looks better than the predecessor.

But very time I open my Air, I think "oh god what have they done".

Why?

I open my MacBook and think "the menu font is badly aliased, yuck" whereas the Mac Pro at work on Mavericks is still a joy to read. And trying to work out where a file is within Xcode is still as simple as right-clicking on the titlebar of the window (like all windows within Mac OS) but on Yosemite, how the heck do I do that????? The titlebar has gone!

I'm on Yosemite with the latest XCode, and all I do is right click on the title bar, as you say, and it gives me the full path to the file ..

Where though? The jumpbar does the same thing (sometimes - it is buggy). But where on the titlebar do I click to get the "file proxy icon" shortcut?

On the window title/filename? Works for me ..

Do you have a screenshot? Because mine looks very similar to the URL below, where as you see there is no part of the titlebar that has the filename on it....

You've written why: the badly aliased fonts.
