- Be sure to install any updates by clicking Update Now and following the on-screen instructions.
4. Monitor your app usage
If you've got multiple apps open that you're not using, this will contribute to slower performance and higher CPU usage, so take a moment to check what's up and running. Quit anything you're not currently using. You can also do it from Activity Monitor. Just select the app and click [x] from the toolbar.
5. Manage your login items
If you have several apps that automatically spring to life each time you start your MacBook, this will also reduce performance and consume your CPU. It's easy to manage and remove unnecessary login items and launch agents; here's how:
- From the main Apple menu, go to System Settings > General > Login Items.
