In the past, firmware updates on a Mac seemed to bring two reboots, and a noticeably different screen when the firmware was being updated.
I didn't see any of that this time, but certainly Apple has been mucking around with the boot displays quite a bit with Yosemite as well.
Same here, no reboots, I had one firmware update on my Mini but I can't recall what it did, I think it rebooted though.
Before this Mini I had a Powerbook G3 and a G4, both rebooted with the different boot screen and restarted after a firmware update.
You guys may want to check your HDD/SSD by doing a verify disk. The 10.10.2 update totally borked my HDD and now I need to repair my HDD. Thanks
No problem here, but after I checked diskUtility hanged, forced quit, and the System almost came to a halt.
