No, MacBooks do not have CD drives. If you need to reinstall the operating system on your Mac, or if it has become corrupted, you would need another physical device that can connect to a USB port. You could purchase an external hard drive that connects through USB, but please be aware it may not have enough space for most operating systems these days. Alternatively, if you are close enough to an Apple Store with one of their devices still in stock they will usually replace yours with a demo model so long as the serial numbers match up.
