I normally use my mac in clamshell mode. Today was the first time since upgrading to Sonoma that I unplugged it and used it as a laptop for awhile.
I just now plugged it back in to my monitor while it was closed. An action that has always worked before. Except today no picture would appear! I tried unplugging and replugging. Nothing.
Eventually I opened the laptop to see if it was still on. It was. I logged in. And macOS popped up a permission prompt asking if I should allow LG Ultrafine. wtf?
