First open the terminal program (you can search through "Applications" → "Utilities" or Spotlight), and then enter the command in sshusername@server_ip format.

Cleaning the MacBook keyboard and screen requires the right method to avoid damage to the device. First turn off the machine and then operate. Use a soft brush to swipe the key seam, and use a dust-tight roller or tape to remove stubborn dust. It can be supplemented with air blowing balls to blow away deep dust, but do not use a high-power vacuum cleaner. When cleaning the screen, use only a small amount of detergent with a microfiber cloth, spray it on the cloth first and then wipe it to avoid detergents containing alcohol or irritating ingredients. Use dry cloth to gently wipe your fingerprints in daily life, and do not use glasses cloth. At the same time, develop good habits, such as not eating slag food on the keyboard, checking for debris regularly, avoiding using it in dusty places, and covering the cover with protective cover against dust.
