                    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.
