I just installed a new version of Steam on macOS Catalina 10.15 (19A602) and got this unexpected request:
Steam.app would like to receive keystrokes from any application
Deny since I can't see any good reason why Steam should need this. I can't find any answers, having looked at a thread on Reddit and Apple Support forums. This security article from Sophos, Synthetic clicks and the macOS flaw Apple can’t seem to fix seems to be related.
Why would Steam need this?
