Panel
Sort by memory to find the heavy one
About
Find a stuck process by name and end it from the palette. Choose Kill Process and type part of the name, its command line or a pid: each row shows the command it runs and its CPU and memory. Return asks it to quit, and ⌘⇧Return force quits it. Quitting asks once more: press again within ten seconds. When several processes share a name, one action quits them all. The panel lists the heaviest processes, by CPU or memory, each with its command line.
- To free a port, use Ports; for the whole-system view, use System Monitor.

Version history
What's new
1.3.0Latest
- Quit, Force Quit and Quit All ask through Stackbar, naming the process and its pid.
- Stackbar 0.35.0 now asks for the second press itself, the same way in the panel, the palette and every window, and VoiceOver reads the question.
1.2.0
- Quit Process, Force Quit and Quit All ask once more: press again within ten seconds, so a stray Return doesn't end a process.
- A process that has quit leaves the results at once, and Stackbar says whether it ended or is still running.
- Processes with the same name show their command line, so you can tell a helper from the app. Search finds a process by its command line too.
- An optional alert, in Settings, for a process that stays busy for two minutes. Its Show button opens the search for it.
- The panel's title names the busiest process and its CPU.
- A failed scan keeps the list you had, under a note.
- Processes of Stackbar plugins are labelled "Stackbar plugin: name", and Dock is left alone.
1.1.0
- The panel's process list now refreshes every minute, and has a Refresh button, instead of showing what was running at launch.
1.0.0
- First release.
