CPU and memory graphs in the MacBook notch

The Stats page on Home shows how hard your Mac is working right now.

See it

Open the notch and swipe to the Stats page. If it isn’t there, add it back in Customize Home, or turn on Show stats card in Settings → Home Page → System Stats.

Settings

In Settings → Home Page → System Stats:

• CPU graph and Memory graph show or hide each graph.
• Refresh interval sets how often usage is sampled. A longer interval uses a little less energy.

Something is using a lot of CPU?

The graphs show the total. To find which app is responsible, open Activity Monitor (in Applications → Utilities) and sort by % CPU or Memory.
