Macbook Pro Retina 2014 - Quick return from Sleep - Black screen with cursor before login window I just got a MBPr. When the display switches off, like its going to sleep and I quickly hit a key to wake it back up. It shows a black screen with a cursor for about 15-20 seconds before the login screen appears. Its only if I do it instantly after the screen switches off. If I leave it off for sometime it comes back instantly... 

Its not a problem when I don't log back in and let the screen go black from the login prompt. 

I also tried to totally disable the show login screen after screensaver/sleep option and it still take a while to go from black to my desktop. 

This is a problem if I have an external display plugged in or no displays attached. Its really annoying because I want to stop it from sleeping because I'm reading or something. 

Is this normal? How can I troubleshoot?
It turns out in this case the cause is Spotify. It seems to be a bug with the Spotify app. Yet no bug fix has been released. If you have spotify running, kill it and see if you get this issue still. 

If you dont use Spotify go through a process of elimination. Start by killing everything running (processes/background/tray tasks) then make the laptop it sleeps and comes back.

Then start processes/background/tray tasks up one by one and let the computer sleep (change it to 1 minute or something to test) then see if it comes back ok. Keep going until it doesn't thats the process at fault.
