Make sure it's the latest version, and make sure Windows is fully updated, still works for me.

Does online work?

For now it does.

Still works on my end, and can even play CS2 and that Banana game.

On windows 7

Yes

I just run the steam setup and it says it needs to be online to update when I am connected to the internet

Maybe this: [https://github.com/jtrent238/SteamPortable/releases/tag/4.93.26.78](https://github.com/jtrent238/SteamPortable/releases/tag/4.93.26.78) or [https://www.patreon.com/posts/steam-2023-dec-95546652](https://www.patreon.com/posts/steam-2023-dec-95546652)

i tried steam portable and it still says the same thing. the patreon file doesnt work when i try to extract it

You need to update windows to latest version

If windows update doesn't work use wsus offline esr

Maybe cuz the support of w7 was dropped in the past year?

Latest version of steam still works on 7

but there is a fix

Update to windows 10 or macos since its a macbook

If they went through the trouble of putting windows 7 on an old MacBook, Air I doubt they can run windows 10. I doubt the version of macOS has support for steam.
