From one moment on the other, OS X Yosemite gets focus every time I type a space in any other application. I don’t need to explain this is very annoying. Fortunately, I found a simple remedy.
What to do if OS X Yosemite gets focus every time you type a space
- Make sure the Finder is active
- In the Apple menu, with the shift button pressed, click Force Quit Finder
The Finder will quit and immediately restart. After that, typing a space in other applications, like Safari and Text Editor no longer took the focus to the Finder.
Hope this helps!
