Most Mac applications, including WhatsApp for Mac, are designed to use CPU and RAM resources efficiently, maintaining moderate consumption. However, there are situations where certain applications may demand a high level of CPU resources for limited periods of time.
The desktop version of WhatsApp for Mac sometimes consumes considerable processor resources, even on a MacBook equipped with a powerful M3 Pro chip. In some cases, CPU usage can exceed 100%, raising questions about the reasons behind this intensive consumption.

Why Does WhatsApp for Mac Use a Lot of CPU Resources?
If you notice that the WhatsApp application has started consuming a significant amount of CPU and RAM resources, there’s no need to worry. It could be a temporary issue that resolves itself within a few minutes.
This scenario often occurs after the first synchronization between the WhatsApp app on your Mac and the one on your phone. The high resource consumption is primarily caused by the process of syncing a large volume of data from the user’s chats. Once this synchronization is complete, older messages from your phone become visible in the desktop app, explaining the increased load on the processor.

Thus, if you notice that WhatsApp for Mac is using a lot of CPU resources, it is most likely the result of syncing a large volume of data between the WhatsApp app on your phone and the one on your Mac.
