I believe I would never see such finder window configuration. But after updating to the latest El Capitan build, I see this, every time I boot to Mac OS X. Figure 1 Literally nothing has left in finder window. This is new for me, though. What I really want is this: Figure 2 Plus sidebar. I need to change to what Figure 2 shows every time booting to Mac OS X. Or I will get lost. Ironically, from Figure 1 style, I finally know how to go back and forward using keyboard shortcuts. (Cmd + up/down) And "need to confirm every app using" issue is present in my El Capitan. Luckily, this only affects startup apps, not Every App. My El Capitan build number is OS X 10.11 (15A244d) Seems a little bit different from what others have posted. P.S.: Where is iOS 9 beta 5?
