Has anyone had issues with updating? Mine updated all the way...then said...calculating...then the button where it said UPDATE said RESTART, but it quickly went back to UPDATE. So I manually restarted & it was a regular restart, not an update sorta restart.

I had the same issue on my new Macbook Pro. (Directly out of the box). Re-ran and it worked fine the second time. Of note, the SSD died about an hour later... Its with Apple right now.

10.10.4 did seem like an unusually long/rough update. For me, the process did ultimately complete automatically with no damage, but there were more restarts than usual, and multiple flavors of sitting on a system screen with a progress bar and no other details. ~2011 27" iMac.
