This section walks you through how to register a device with a specific serial number and save it into the online device registry. This is helpful if you want to manually register a device offline or pre-provisioning devices.
The following instructions are provided to register devices with serial numbers using Apple's device registration protocol. This is a special protocol for device registration and you can obtain details on how to implement device registration protocols in your application in iOS/macOS .
A device registration protocol is used to register devices with an Apple server (online or offline). For example, Apple's device registration protocol can be used to register a device with a device with a specific Serial-Number and allow the device to join the device's local network. Your device will be automatically registered once the device is connected (online) to the network.
In addition, the checksum will be an 8-digit integer, starting at zero. Starting with macOS Catalina 10.15, the checksum field is equal to the checksum of the device’s serial number. This means that the checksum of your device serial number will match the checksum of the device’s serial number stored in the system. For example, if you were to run the following command, the checksum of the serial number on your device would be displayed.
I also assume that only one machine will be assigned a new serial number, and that the serial number will be notated with a MAC address. Apple hasn't announced any plans to roll out a public beta yet, so I would imagine that there is a window of opportunity. This is of course, Apple's call, and as it stands, if you have a device with a serial number that is relevant to MacRumors, you can email us at firstname.lastname@example.org with the information, and we will send them over.
The serial number will be an alphanumeric string of 8 characters to 14 characters in length, and will begin with a letter indicating the model, followed by a number, and then followed by a letter indicating the manufacturer (e.g. ABCD 1234A).
It's always a relief to know the serial number of the device, and being able to boot an OS X install disc enables you to run a repair that will hopefully repair the drive and return your Mac to working order.
Apple serial numbers can be found on the bottom right-hand corner of the computer. If your Mac is an iMac, Mac mini, MacBook, or Mac Pro, look for the serial number at the bottom left-hand corner of the device. If your Mac is a MacBook Air or Mac mini, the serial number will be on the bottom right-hand corner of the computer. 827ec27edc
