Step-by-step solution

1. Check Available Storage

   Ensure you have sufficient free disk space

   Click Apple menu > About This Mac
   Click "Storage" tab
   Review available space

   Note: Keep at least 10-15% of your disk free for optimal performance

2. Manage Login Items

   Reduce programs that start automatically when you log in

   Go to Apple menu > System Preferences
   Click "Users & Groups"
   Select your account and click "Login Items"
   Remove unnecessary items

   Note: Keep only essential applications in login items

3. Update macOS and Applications

   Install the latest updates for optimal performance

   Click Apple menu > System Preferences
   Click "Software Update"
   Install available updates
   Update apps from App Store

   Note: Restart after installing major system updates

4. Monitor Activity with Activity Monitor

   Identify and quit resource-heavy applications

   Open Applications > Utilities > Activity Monitor
   Click "CPU" tab to sort by processor usage
   Select high-usage apps and click "Quit Process"

   Warning: Don't quit system processes unless necessary

5. Reset SMC and NVRAM

   Reset system management controller and parameter RAM

   For SMC: Shut down Mac, press Shift+Control+Option+Power for 10 seconds
   For NVRAM: Restart and hold Command+Option+P+R until you hear startup sound twice

   Note: This resets various system settings to defaults
