"Critical Update" loop

Hiya!

My MacBook Pro, unexpectedly and unprompted, shut off today and when it booted back up it claimed there was a "critical software update" that needed to be installed. So, naturally, I chose a WiFi network and did the update. Mind you, this was before getting to the log in screen. After this, I noticed that my wireless mouse wasn't working. It turns out the USB-C ports on the left side weren't working. I've done research online and the consensus is an SMC reset is required. I did one and I'm not entirely sure if it worked as the prompt came up once again. Thinking I may have done it incorrectly, I tried again to no avail. At this point, I'm using my USB-C adapter (Satechi brand) on the right side and plugging the computer into the good port on the left side. Has anyone else had this problem?

MacBook Pro TouchBar and Touch ID, macOS High Sierra (10.13.2)

I had the same issue on the morning of 12-23. Tried every reset as well as reinstalling backups, new OS, but it still would go back to the same “critical software update needed” screen. I took it into Apple and they are now sending it off to the techs to open it up, to make sure nothing mechanical is causing this. Pretty certain I haven’t spilled any liquids and the power hasn’t gone out so I don’t know if they’ll find anything broken but we’ll see. I should hear back after the 1st. I’m just glad I have insurance and a desktop pc at work. I’ve seen other posts about this update loop so we’re not the only ones. (2017 15” MBP)
