Given the lack of information all I can guess is:
Spinning globe
If you see a spinning globe instead of an Apple logo, it means your Mac is starting from a network-based startup disk like Netboot or Internet Recovery instead of a connected or built-in startup disk. If you didn't mean for your Mac to start this way, press and hold the power key to turn off your Mac. Then, press the power key again to start up normally.
If your Mac always starts to a spinning globe and you're at a school or business, check with your IT department for more information. There might be a server on your network that your Mac is trying to start from. If this is your personal Mac, try starting from macOS Recovery to check your startup disk and macOS.
