William, Thanks for that data point also at 11:30. I suspect We’ll see if this is an actual thing soon :) -mel via cell

We are also in Ventura County.

None of our apple/mac devices were affected. They are all fairly recent (at least ARM)

However, I personally did get an iPhone notification at THAT TIME (approximately 11:30 am) that they were planning on installing IOS 18.3.2 later tonight.

Sincerely,

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?

Jay, Thanks for that data point as well. I do see that several news reports say that this is an urgent upgrade due to an active zero day attack. -mel via cell

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.
