I wanted to give a try to Crossover on my M1 Mac with Steam. But no matter how I install Steam in a new bottle (from the automatic "Install a Windows Application" or manually setting it up in a new bottle), the install runs fine, but Steam get stuck at launch complaining I must get online (which I am). I've unfortunately already tried the "-udpforce -allosarches -cef-force-32bit" trick to no avail.
Usually this error is related to local network settings. If you have iCloud Private Relay enabled, I'd try disabling it. And if you find that you can connect through VPN, that's also a good sign that something in your network is at fault.
I had already disabled Private Relay on each interface in the network settings but apparently that didn't do it. When I also disabled it in the system preferences Apple ID section it all started working immediately. How frustrating! Thanks for the tip.
We're rebels. We're misfits. But mostly, we're software liberators. And we're very, very good at what we do. We have to be. Lots of developers work with open source, but only a tiny fraction of those are good enough to get software that was designed for one platform to work on another one. We invented CrossOver software - a unique approach to cross-platform compatibility that does not require dual-boot or another OS license. We launched PortJump to help app and game developers broaden their market beyond Windows® users. And we launched ExecMode to help organizations solve really ugly technical challenges.
