Office applications on MacBook usually consume more CPU than memory. This is because office applications need to deal with a lot of data and graphics, including text, pictures, tables and so on. These operations require a lot of computing power to complete, so they will occupy more CPU resources.

Of course, when using Office, it will also occupy a certain amount of memory, especially when opening multiple documents or performing complex operations. But overall, the CPU utilization rate is higher.

If you find that your MacBook is running slowly or has other problems, please try to close some unnecessary applications to free up system resources and ensure that you are running the latest version of Office software.
