What is the spinning beach ball on Mac
When a colored circle appears on a Mac, it usually means that the application is slow to respond, which may be caused by high CPU or memory usage, application errors, disk read and write problems, or graphics delays. 1. When you encounter a circle, you can wait for a moment; 2. Use the activity monitor to view and force exit the process that occupies high resources; 3. Force exit the unresponsive application; 4. Regularly save work to prevent data loss; 5. Restart the device if there is no response for a long time. To reduce this phenomenon, the system and application should be kept updated, avoid running too many programs at the same time, clean up storage space, reset NVRAM/PRAM regularly, and view logs through the console to troubleshoot problems.
