Can't Update Mac Using Hotspot. Help

Ask your carrier for a mobile hotspot. That usually gets local Wi-Fi with 5G backhaul, and can allow the existing Wi-Fi to be shut down.

Depending on details and expectations, Starlink might be another option.

Another potential option is troubleshooting the existing Wi-Fi, and resolving the issue(s) with that.

I can't update my Mac using my iPhone hotspot. No error codes, just zero progress in installation.

The hotspot connects just fine, allowing me to stream media, log into websites, etc. it just won't allow the update.

My wifi is awful and I have no alternative forms on connectivity. Hotspot is my only means of reasonable network speeds. Is there anything that can be done?

I've turned off low data mode, I turned on and off every network setting available. Nothing.

Please help. I'm using an M1 Mac mini and an iphone 15 pro max. Incase those details matter at all

The OP didn't ask about updating an iPhone, but about updating a Mac.

The Mac is connected to the Internet through the iPhone's Wi-Fi Hotspot, and apparently the Mac -- (Wi-Fi) -- iPhone -- (cellular data) -- Internet connection is not able to handle downloading and installing macOS, at least not via Software Update.
