With the advent of Yosemite, OS X has received the largest number of changes to the interface. And some of them can hardly be called successful. Below, we will discuss how to solve the most vexing problems of 4 OS X Yosemite.
Transparency
As we have said in this article, The effect of transparency - it is not only questionable design decision, but it also slows down the system and can be seen with the naked eye even on the latest MacBook Air 2013.
To disable the transparency effect, go to System Preferences, go to the tab and select Universal access "Monitor". Here, check the box "Reduce transparency" and you will immediately notice how animation systems have become much smoother and faster.
The missing panel in iTunes
From the earliest versions of iTunes sidebar always showed the connected devices, playlists and various media. In iTunes 12, Apple for some reason decided to get rid of the element to which all used to.
However, to enable the sidebar, though not in the past, as it is still possible. To do this, click on the "Playlists" at the top. The panel will display playlists and media files. Better than nothing.
Where the address bar?
By default, Safari no longer displays the address of the current site. For most people - this is not a problem, but I, for example, this is not enough.
Fortunately, this is easily corrected. Go to the Safari settings tab in the "Add-ons". Here we put the topmost checkbox "Show full web address."
Too much information
Despite the fact that most useful Spotlight features do not work outside the US, it is still easy to use to find various files and programs.
However, with the advent of Yosemite, Spotlight started to show too much information and some still need to be turned off. This can be done in System Preferences, in the Spotlight tab. Here it is necessary to remove the check mark from the categories in which you do not need.
And bonus chips in the Spotlight configuration is that the category can be swapped by dragging them with the mouse or trackpad. Thus, you can vary the display of information and make the top shows the most necessary needs.
