Hi, I just got a new MacBook Pro (Retina, 13-inch, Early 2015) on which I preformed a clean installation of OS X Yosemite v10.10.3. At startup it's exhibiting some odd behavior about 50% of the time. So what happens is as follows: Turning on the MacBook Pro by pressing the power button on the build-in keyboard After a second or so the login screen appears with my own custom set desktop picture visible Logging in by entering my password, password is accepted and the actual startup indicator appears When the progress bar is about half through the screen goes black MacBook Pro restarts, startup sound can be heard Login screen appears once again, but this time around with the default OS X Yosemite desktop picture Startup indicator goes all the way through and my desktop with custom set desktop picture appears MacBook Pro functions as normal This cycle happens after a shutdown as well as after a restart (ending up restarting twice due to this problem). Do any of you have a clue as to why this is happening? I only owned Mac desktops before, so I don't have much experience with their notebooks.
