The article advises MacBook users to diagnose the source of slow performance before using cleanup tools, resetting the device or replacing it. It recommends starting with a restart, then checking storage, processor and memory use to identify whether a particular app or system resource is causing the problem. This matters because targeted changes may resolve avoidable slowdowns without unnecessary or more disruptive measures.

Users can review disk space in System Settings, use Activity Monitor to spot demanding CPU processes and watch the Memory Pressure graph for signs of excessive RAM use. The article also suggests removing unneeded login items, reviewing background activity, uninstalling unused apps and ensuring Low Power Mode is not limiting performance when speed is the priority. Keeping macOS up to date may improve stability and compatibility, while High Power Mode is intended mainly for sustained intensive work on supported MacBook Pro models.
