Hi. I'm new to the Mac world so please forgive me for this "stupid" question. It's my understanding that when there's a blue light under an app on the dock, that means that it's active. In any case, I just noticed that there's a blue light under the Finder app even when I don't have it open and when I click Command and Tab, it shows the Finder app. I've tried to force quit and instead of allowing me to force quit, it allows me to only click "relaunch." I've shut down and restarted and the same thing. The thing is though is that I could have sworn that it wasn't like this when I first got the computer. I recalled that I was able to open the Finder app and then click the red bubble and close it out and I don't remember seeing the blue light under the Finder app on the dock. I guess I'm hoping someone can check their computer and tell me the status of the blue light on their computer (maybe after a restart with nothing open.) Maybe I just never noticed it was always on and maybe I was wrong in thinking that it ever turned off when I closed the app but I could've sworn that it did turn off. Can someone check and tell me one way or the other? Thanks.
