I updated my 2019 MacBook Pro yesterday, and today I turned on my laptop, logged in, and when it finished loading everything I plugged in my LG Ultrafine 24 inch – and nothing. No monitor recognized, no disks mount that were attached, etc.
I’ve had plenty of weirdnesses with external monitors and laptops, including this one, over the years, but I’ve never had absolutely nothing happen.
I unplugged the monitor from the computer and then reconnected it, and it worked. But yeah, something’s not right.
