'Steam' - Enabling 'Access for assistive devices'

In Mavericks, the old "Enable access for assistive applications" setting in Accessibiliity (formerly Universal Access) preferences is gone. Instead of enabling access globally for all applications at once, you must grant access to one application at a time.

To do this, open System Preferences, click Security & Privacy, click Privacy, click Accessibility, drag the Steam application icon into the list, and select Steam's checkbox. You should then be able to use Steam.

Thanks - this time, when I started Steam, it updated and I got a prompt directing me to the Security & Privacy PrefPane, as you described. Steam was already on the list, but unchecked. I unlocked the PrefPane and checked the box.

To me, the real question is "why on earth does Steam want this on in the first place?!". Surely this is one of those settings that you activate if you need it and don't if you don't. It shouldn't be forced on you.

...since the above question was posted no one has answered...& this is my question too, why do Steam need it? My boys want to play Counter Strike, Steam asks for access to my computer for an overlay...so how dangerous is this permission, deny or allow?😕
