I am in Ventura county, California, and just now at 11:30AM PT we had an iPhone, an iPad, and an iMac all crash simultaneously. The Ethernet-connected iMac had a black screen of death, and the iOS devices were on WiFi and had to be power cycled. These would seem to have to have been network-initiated events, and the iPad when it came back online said “Your device has been updated to 18.3.2”. The iPhone 16Pro, was updated to 18.3.2. yesterday and displayed no unusual message upon power-on. The iMac is an older model Retina 5K 27” from 2014 running MacOS 10.11.6.
I had something similar happen to an Intel Macbook Pro. Yesterday evening I got a pop-up that there was an update available, and was given the option to "Try later tonight", which I accepted. When I opened the laptop this morning it immediately went through the update process, multiple screens with Apple logos and progress bars, taking a good six minutes to boot. It is now running MacOS Sierra 15.3.2 and seems to be functioning OK, but I wouldn't be surprised to find some things broken like custom SSH settings, etc. that Apple seems to like to mess with during upgrades. This seemed to be a regular software update except that it waited until I opened the lid this morning rather than happening in the middle of the night. -- Jay Hennigan - jay@west.net Network Engineering - CCIE #7880 503 897-8550 - WB6RDV
