Activity Monitor doesn't show the "Kind" column, and does not give me the option to enable it. It's not in the list of columns I can enable.
My friend's M1 Mac has the Kind column in the list of columns he can enable. It's between Real Shared Memory and Sudden Termination. It's not there for mine. The light-colored screenshot is my Mac. The dark-colored screenshot is my friend's. You can see the Kind column is highlighted on his, and missing on mine.
I've tried deleting Activity Monitor preferences to no avail, and of course I've resized the window and made sure it's not already showing off the edge of the window. It's like the column never existed.
