Audit Your Startup Items

Most of the time, a slow Mac is caused by too many background processes fighting for memory. Go to 'System Settings,' search for 'Login Items,' and remove any applications you do not need to launch immediately upon startup. This frees up RAM and CPU cycles for the apps you actually use.

Clean Up Storage and System Junk

macOS needs a certain amount of free space—typically 10-20% of your total drive—to perform internal maintenance tasks. Use the built-in storage management tools in the 'About This Mac' section to identify large files or apps you no longer need. Additionally, ensure you are running the latest version of macOS to benefit from performance optimizations and bug fixes.
