Review one by one
Go through your heaviest apps in turn: show and close, keep, or skip.
When memory is tight or short, Now offers Review one by one (also Go › Review One by One…, ⌘R). It lists your apps using at least 200 MB, heaviest first.
- ⏎ Show and close: brings the app forward. Close it with ⌘Q, and Review moves on, showing what came back.
- K Keep or → Skip: moves on without closing it.
- Esc: finish.
At the end it tells you how many apps you closed and about how much came back.
