Sandboxed Mac apps can record screen any time without you knowing
I was an AppKit engineer when the Mac app sandbox was introduced in 10.7. Much of our effort that release (and in following releases) was dedicated to making Mac features work within sandboxed apps. Think open and save panels, copy and paste, drag and drop, Services menu, Open Recents, etc.<p>We did our best but the fact is that sandboxed apps run more slowly, have fewer features, are more isolated, and take longer to develop. Sometimes this cost is prohibitive (see Coda 2.5).<p>IMO the app sandbox was a grievous strategic mistake for the Mac. Cocoa-based Mac apps are rapidly being eaten by web apps and Electron psuedo-desktop apps. For Mac apps to survive, they must capitalize on their strengths: superior performance, better system integration, better dev experience, more features, and higher general quality.<p>But the app sandbox strikes at all of those. In return it offers security inferior to a web app, as this post illustrates. The price is far too high and the benefits too little.<p>IMO Apple should drop the Mac app sandbox altogether (though continue to sandbox system services, which is totally sensible, and maybe retain something geared towards browsers.) The code signing requirements and dev cert revocation, which has been successfully used to remotely disable malware, will be sufficient security: the Mac community is good at sussing out bad actors. But force Mac devs to castrate their apps even more, and there won&#x27;t be anything left to protect.
