Hi There, I am trying to install Steam onto my iMac, which runs MacOS Cataline 10.15, yet whenever I install and try open a dialogue box reading "steam_osx" is damaged and can't be opened. You should move it to the bin." appears and the only options are "move to bin" and "cancel" which closes the box and ends the installation. I have attached an image below but please help me, nothing on the internet seems to work
iMac 21.5″, macOS 10.15
I re-installed over the weekend. It doesn't do anything. The software works fine on an account with administrator privileges. It does not work with a standard user. Steam auto updates when it is opened, but it doesn't ask for administrator credentials. It just throws the error that it is damaged.
But, I just figured it out. I opened a Terminal and ran Steam as the superuser with the following command:
sudo /Applications/Steam.app/Contents/MacOS/steam.sh
It ran the update and then exited. When I double clicked on Steam in the Finder, it opened like it should.
I first had to go back into my administrator account and edit the /private/etc/sudoers file to add the kid's account. Otherwise, you can't use sudo. So, technically now the kids can get admin privileges on the command line, but they don't know unix. Security through obscurity :-)
If this is too complicated, then just run Steam in an account that has Administrator privileges and it should work. Hopefully they fix this in a future release. Origin doesn't have this problem...

I have this issue, too. I am running the 64-bit version of Steam, and it works on my account that has administrator rights. When I open this in an account that doesn't have administrator rights, it says that the application is damaged. I don't want my 13 year old to have administrator rights on the Mac...
Any suggestions?
Hi there,
Let's try the download again. Go to the downloads folder, and drag Steam to the trash. Then, go to the Steam website, and try downloading it again.
If it is already installed, drag the app to the trash from Finder, and reinstall the app.
Cheers,
Jack
