Tips for using Mac OS: What should I do if the system loses response ?, OS usage skills


Even a better system and a faster version will cause choppy or dead-end responses during running. Mac users may also encounter this situation from time to time. The most common manifestation is that the mouse turns into a colorful circle, and the system usually recovers after a while. If the response is delayed, you need to handle it.
Note: Use the memory cleanup software with caution. If you use other or excessive commands during memory cleanup, it is likely to cause a long period of downtime.
The following describes how to cope with system response loss or card freezing.

(1) Click the apple key in the upper left corner to force exit, or press command + option + esc. Then we can see all the currently running apps, you can force exit. Note that the Finder can only be restarted and cannot be forcibly exited.

(2) Press and hold option and right-click the application icon that loses response on the Dock. In the displayed shortcut menu, click force exit.
(3) Enter LaunchPad, utility, open activity monitor, select the APP to force exit, and click the cross button in the upper left corner to force exit.



(4) When the system bar displays the current APP instead of the Finder, you can press [command] + [option] + [shift] + [esc] for two seconds at the same time, the current application automatically exits. If your MacBook crashes, try these methods.
