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’m reporting this here in case an Apple-initiated automatic network update process is running amok. In my experience, Apple products never update without telling you first, and even automatic updates have always happened in the dead of night and require the device to be plugged into power. The probability of three devices, all from the same manufacturer, randomly crashing simultaneously, seems remote. Which is why I suspect something network driven. None of our linux, android, or windows devices were affected. Has anybody else seen something similar? -mel
