Steam overlay is not Working

Hello, i found a solution. Go to this website: http://mac.filehorse.com/download-steam/5515/ and then download it. don't mess with the versions section, just download the file and then run it. it will update it and change the logo (if the logo is older) but don't worry about that. just keep going, Next step is that you have to go to settings, Security and Privacy settings and go to accessibility section and then remove the Steam thing with the - button, after that. re - add it after deleting the new steam that u had (the one that didn't work with the overlay) then keep the one u just downloaded in ur applications (or where ever u put ur steam) and then re - add it in the Security Privacy/ Accessibility settings and it should work fine 🙂

Please state which game?

I assume this steam game came off Apple Store? If not, my advice is run away from it.

It's highly possible that the maker is not updating the game and that if you update Sierra the game will stop working. look on apple store and check the supported versions of Sierra. If a maker chooses not to continue supporting new apple versions, there is nothing that can be done but speak to the maker.

A game should not "need to control your computer" every time it runs but may need a password when first installing (it's up to you if the game is worth trusting for even an install-time permission). The game should never access non-game data without your permission, and the maker is under contract with Apple that it not do so. Which is a huge benefit of using Apple's App Store.

You shouldn't download binaries and run them (it could be dangerous to imac, or breach your security). if the steam game has an update it will appear and install in app store updates.

Perhaps remove ~/HOME/Library/gamestuff and re-download the game. perhaps it just doesn't "update well". Insure you get your game saves outta there before you try 🙂

you need accesibility allowed (should require not password?) for games that utilize "notifications"

notifications should be harmless to allow: however wait for an update, do NOT download binaries posted because someone told you "it's ok don't worry". worry.

Nope doesn't work, i put a solution that should work. atleast it worked for me

Might be a corrupt .plist.

Do a backup, preferably 2 backups on 2 separate drives.

Quit the application.

Go to Finder and select your user/home folder. With that Finder window as the front window, either select Finder/View/Show View options or go command - J. When the View options opens, check ’Show Library Folder’. That should make your user library folder visible in your user/home folder. Select Library. Then go to Preferences/com.apple.systempreferences.plist. Move the .plist to your desktop.

Restart the computer, open the application, and test. If it works okay, delete the plist from the desktop.

If the application is the same, return the .plist to where you got it from, overwriting the newer one.
