Does anyone know what error 702 on system installation means?

Does anyone know what error 702 is or means and/or what can be done about it. This occurred during a system installation, probably three quarters of the way through. The latest time it occurred for me was during Ventura installation. This is the message I got on a Sonoma installation. The same thing happened with Ventura.



Thanks very much.

Hey, thanks for the additional information. Even with a bootable USB, the mac still requires an internet connection. This is not needed to download macOS, instead the internet connection is required to retrieve firmware and other information related to the model of the mac. Check out this link here for more info.

Hope this helps!

Good question, and I'm certainly not an expert on how all of the backend mechanics work. But this is my understanding of the process. When you boot from a macOS installer (like a USB drive), the installer on the USB includes the necessary network drivers. During the setup, you may select a Wi-Fi network with the menu in the top right corner, or connect via Ethernet. With that connection, it can then download any additional drivers or retrieve necessary information for the installation. Hope this helps!

I don't know what the error code is but may have a workaround for you: boot into Safe Mode according to How to use safe mode on your Mac and try installing from there. That helped me on a couple of occasions.


Note:  if you have a wireless keyboard with rechargeable batteries connect it with its charging cable before booting into Safe Mode.  This makes it act as a wired keyboard as will assure a successful boot into Safe Mode.


Just some food for thought.

Hey, thanks for the update. It looks like it's having a hard time downloading the needed files for the installation. Are you on wireless? If so, are you able to try a wired connection? That can also happen from the time being off in the recovery environment. This link can help you manually change it from the terminal if you're comfortable running commands.

Lastly, you could also try to reset your NVRAM. Here is Apple's article for that.

Does any of that help you?
