Just as a quick update, this afternoon I had another problem which isn’t “supposed to happen” in MacOS. When I arrived home from school, my laptop was burning hot in my bag. When I opened the screen, there was an error message telling me I needed to hard-power cycle my macbook by holding in the power button, because of an error. It was a kernel panic, but the laptop was left in some continuous processing loop, with the fan spinning, but doing no good in my bag, while an unhelpful message was telling me to power cycle it. So much for Mac’s “Just working”. At least with other OSes, I expect such errors, and am very careful about making sure they aren’t happening.
