For example, the macOS Photos app might be performing image analysis on a set of photos you recently imported. Sometimes, this isn't something you explicitly requested. If you've already told an app to do something, you might as well give it some time to finish the task.

In these cases, waiting is the best option. It might even pop up when you're connecting to a server in an online game. For example, it might appear when you're trying to render a video in an editing program or perform batch edits in a photo-editing app. Many times, the spinning wheel of death appears when an app is trying to do something. Resist quitting the app just yet and move on to the next step. You might also see "(Not responding)" appended after the app name in the list. See if any are using more than their fair share of CPU resources. This puts the thirstiest apps at the top of the list.
