Many OS X apps are utilities that help you work with other apps. Running all the time in the background, monitoring, looking at keyboard input, observing folders, etc. These types of apps are fundamentally at odds with the Sandbox. But they&#x27;re used often by many&#x2F;most OS X users, even the less technically inclined.<p>Whereas the design and simplicity of iOS has ensured, from the start, that these types of apps <i>cannot</i> exists on that OS.<p>&gt; Are the sandbox limits really too restrictive for most apps (I guess new APIs&#x2F;permissions could improve that with time)<p>The last 5 years have proven that Apple is not interested in granting exemptions to the Sandbox or new entitlements for, say, Accessibility apps.
