About Aide
Activity Monitor has the answer when your Mac slows down, but you have to open it, sort a long list and guess which process is the culprit. Aide sits in the menu bar and stays gray while everything is fine. When CPU or memory use crosses a limit you set, the indicator changes color and the list shows only the apps over it.
From there you can pause an app, resume it, restart it to free memory, or kill it. It's paid: the demo runs free for 24 hours, then it's a one-time $4.99 license via Gumroad. Worth knowing before you try it: you pick the limits yourself, so it needs a little tuning at first.
