MacBook Pro 2016 (Touch Bar) in “Critical Update” loop So my MacBook Pro has been experiencing some weird issues after an unprompted and unexpected shut down. When I turned it back on, it claimed there was a “critical software update” and asked to choose a WiFi network. So I did so and it installed and after two minutes it was done. However, the USB C ports on the left side had stopped working. I was using a satechi adapter and removed it to find that the charging cable only works on one of the two ports now. The right side ports will work with the adapter usually. I did a SMC reset and reinstalled High Sierra, so before I do a full wipe I want to see if anyone can give me an answer.
Weird enough I just had this, I unplugged all the USB-C devices and then did a power cycle and it booted fine. I think it's time to build a backup computer.
