Step 1

Glance at iStat Menus in the menu bar — if CPU or memory spikes, identify which app is the culprit in the MEM table before it becomes unresponsive

Step 2

Open QuitAll from the menu bar, find the frozen app in the list, and switch from Quit to Force Quit to shut it down immediately without touching the keyboard shortcut or Apple menu.

Step 3

If multiple apps are quietly eating resources in the background, hit Quit All in QuitAll to wipe the slate clean in one click — no hunting through the Dock one by one.

Step 4

Open CleanMyMac's menu bar monitor and switch to the CPU view to see which processes are misbehaving — then quit them directly from the same panel without opening Activity Monitor.

Step 5

Use CleanMyMac's maintenance scripts to clear system caches and repair permissions — the kind of quiet buildup that causes apps to freeze or hang more frequently over time.
