To clean the screen, first shut down your MacBook and unplug the power adapter. Use a soft, lint-free cloth slightly dampened with water or a screen cleaner. Gently wipe the screen, avoiding excessive pressure and liquid contact with ports.

Reduce screen brightness, close unused applications, and disable Bluetooth if not in use. Use Energy Saver preferences to maximize battery performance and calibrate the battery regularly by fully charging and then completely discharging it.
Ensure proper ventilation by using the MacBook on a hard, flat surface. Check for dust accumulation in the vents and clean if necessary. Monitor CPU usage for apps that may be overloading the system. Consider using a cooling pad.
Use a Mini DisplayPort to VGA or HDMI adapter, depending on the external display's input. Connect the adapter to the MacBook's Mini DisplayPort, then connect the cable to the external display. Adjust display settings in System Preferences under "Displays."
Regularly back up data using Time Machine or another backup solution. Run Disk Utility to check and repair disk permissions and verify disk integrity. Keep the operating system and software up to date to prevent potential issues.
Go to System Preferences > Security & Privacy > FileVault. Click the lock icon to make changes, then click "Turn On FileVault." Follow the prompts to encrypt your startup disk and choose a recovery method. Ensure you store the recovery key in a safe place.
