You can then download and reinstall Steam from this website (Install Steam link at top of page) after the reboot, and the issue should be gone. Games do not install and keeps saying it lacks its executable files.

I have tried to a you've suggested, yet it doesn't work for me. The restart step is very important, do not skip it! (If you do not see a prompt, then your saved files will not be deleted, as the default behavior is Keep.)Įmpty the trash, verify that Steam is no longer an application on your system, and then fully restart your Mac. You will be prompted to Keep or Discard related files - you should choose KEEP in order to retain your saved games and local downloads. To do this, drag the Steam application to the Trash. If the problem still continues after a restart, you may need to perform a full re-installation of the Steam application (but not your games). First, please try the directions at to refresh your local files (including a system restart). If this happens to you after Steam restarts itself for an update, there are two options.

Due to an unexpected compatibility issue between new OS X security features and our January 1 update, some users may see an error message saying 'Failed to load steamui.dylib' which prevents Steam from starting up properly.
