Combined processes #

When showing per-app memory, iStat Menus combines child processes. Combining child processes shows a total that covers the full footprint of an app. For example, each Safari tab is a separate process, and by default they are shown as separate items in Activity Monitor.

This means if you’re comparing the figures to a single process in Activity Monitor, they will not match — to get the same calculation, you’ll have to add up the processes shown in Activity Monitor.

If you’d like to stop iStat Menus from combining processes, please disable “Combine Processes” from the Stats menu.
