Yes, you can sign into your Apple ID account on MacinCloud Servers
However, you will not be able to create a new Apple ID on MacinCloud servers, and you must bring your own existing Apple ID to use with the service. If you wish to create an Apple ID you must use your own Apple device or Windows PC. See Apple's Official documentation for step-by-step instructions on how to create an Apple ID.
