Have contacted Steam support will et you all know if I hear anything

It seems that the Steam installer is not setting up its environment properly. I was able to get this working by creating a few symlinks to the Chromium Embedded Framework where steam expects it to exist.

Details are here https://www.reddit.com/r/macgaming/comments/1n1xfsl/comment/ndkzu7t/

Hopefully this is something steam can sort out with their installer.

oh thank god it’s not just me, i thought I was going insane. I sent a message to steam support and everything.

Hi, thank you all for the reports detailing this issue. This was a regression in the Steam client public update that was released yesterday that primarily affected new installs of Steam. This should now be fixed.

Restarting the Steam client should cause it to download and install the new update. If not, launching, force-quitting the Steam app, then starting it again should force an update check.

Alternatively steps to remove and reinstall the client can be found here.

Yup. works perfectly fine now :)

If it doesn't respond when opened, click the file located at /Applications/Steam.app/Contents/MacOS/steam.sh. Then you'll be able to use Steam.

For me, nothing has changed, it’s still not working.

Uninstall the app and reinstall it, that's what worked for me

zsh: killed /Applications/Steam.app/Contents/MacOS/steam_osx
