Security research firm CoreLabs Research recently disclosed a potential vulnerability in Apple's desktop operating system, ArsTechnica reported on Friday.
Sandboxing provides a method for an operating system to restrict which system resources are available to an application. According to the security firm, vulnerabilities in the feature extend to the three latest releases of Mac OS X: Leopard, Snow Leopard and Lion.
But if I chose the 'Mac Appstore Distribution' identity or the 'Mac Development' profile then it properly loads the receipt on my development Mac but it does not work on other computer. It starts the app and always exit with the code 173 and nothing else. Is it possible to test IAP in sandbox on a Mac where the application has not been built? “So glad my wife and I were introduced to Sandbox. I really like the ability to attach a photo at the end of the letter. Our son has commented that he really enjoyed the photos we’ve sent over the weeks. This app is great as it allows for tracking and if I get my letter in on time he gets it the next day. @SGaist said in Sandbox app for the Mac App Store with Qt 5.8 and QtWebEngineProcess: The switch doesn't remove the build of the helper application, it disable some code that is using APIs not authorised in App Store applications. Do you know if these API were present in 5.7?
'Several of the default pre-defined sandbox profiles don't properly limit all the available mechanisms and therefore allow exercising part of the restricted functionality,' the vulnerability's description read.
In particular, an application without approved network access could send Apple events 'to invoke the execution of other applications not directly restricted by the sandbox.' The firm also noted that the issue resembles one reported by famed security expert Charlie Miller at the Black Hat Japan security conference in 2008. Apple apparently fixed the mentioned issue, but neglected to 'modify the generic profiles.'
Apple had originally required all submitted Mac App Store apps to support sandboxing by this month, but the company recently pushed the deadline back to March of next year.
'As of March 1, 2012 all apps submitted to the Mac App Store must implement sandboxing,' Apple reportedly said in an email to developers, as noted byTUAW.
The Cupertino, Calif., company is implementing the policy in an effort to maintain security on the Mac App Store, but a number of developers have complained that the rule is overly restrictive. The recently revealed vulnerability has only added fuel to their cause, as some assert that the sandbox requirement is flawed because sandboxing itself is vulnerable.
Some have also taken issue with how Apple has handled the news of the vulnerability. Core notified Apple of the issue in September to allow ample time for it to address the issue before going public with the problem. According to the firm, Apple responded that it 'does not see any actual security implications' because documentation for the NoNetwork sandbox profile does not actually promise that Apple events will be blocked.

Core replied that the vulnerability allows Apple events to eventually execute sockets-based networking, which is supposed to be blocked by the NoNetwork sandbox profile. Apple then agreed to modify its documentation to make note of the issue.
While the Mac App Store is only one option for adding software to a Mac, some critics of Apple's restrictions have voiced concerns that the company could move toward the iOS model. The App Store on iOS is currently the only legitimate source for applications on the mobile OS.
For its part, Apple has moved its own software onto the Mac App Store, even going so far as to launch Mac OS X Lion exclusively on the store in July. The company also released Final Cut Pro X in June only on the Mac App Store.

Introduced in 2007 and required by 2012, sandboxing is a tool used by macOS to limit the damage that a hijacked app can do. Apple says, “While App Sandbox doesn’t prevent attacks against your app, it does minimize the harm a successful one can cause. macOS app sandboxing protects users by limiting how much trouble an application can cause.

What is macOS App Sandboxing?
Each app gets its own area to play in: a “sandbox.” If the application wants to reach outside its sandbox, it needs to ask the operating system for permission. Depending on the sandbox settings, the OS will either deny or approve the application’s request while providing the least specific information possible to complete the request.

Think of a car. The driver is protected by multiple security features like anti-lock breaks, air bags, crumple zones, and more. In 2007, the time of App Sandboxing’s introduction, no analogous computer systems existed. As the introductory presentation asked, where were the seat belts for computers? Sandboxing protects users like cars protect their drivers: meeting failures with damage-reduction systems. Whether caused by malicious activity or coding errors, damage goes down.
Because sandboxing limits what apps can do, it can restrict developer freedom. Sandbox apps run more slowly and take longer to develop. Why wont my facetime app open on my mac. Thanks to the Mac’s enormous capability, sandbox limits can have a huge impact on the compatibility of various apps. As a result, power users are often driven to choose apps that run outside the sandbox, either for performance or feature issues.
How Does App Sandboxing Work?
Sandboxing is based on the principle of least privilege. In short, systems can do what they need to do but no more. By limiting each part of a system to completing only its declared goal, you reduce the chance of your app being hijacked. For example, there’s no reason for a flashlight app to have access to your contacts list.
Apps can reach outside their sandbox but only with operating system permission. Take the “Save and Open” dialog box in macOS. The app, inside its sandbox, cannot directly access filesystem resources on your hard drive. It cannot, for example, draw an open panel at “~/Documents.” Instead, the app must ask the Powerbox API with NSOpenPanel and NSSavePanel classes to access the panel.
The application cannot see what’s happening inside Powerbox directly. Only the opened or saved file will be accessible to the app. This way the apps can perform critical functions without unnecessary risk.

That functionality is enabled by an entitlement (specifically com.apple.security.files.user-selected.read-write). App developers set entitlements which declare what an app does. Based on the declared entitlements, the operating system permits the application an appropriately-limited level of functionality.

This thought process underlies the entirety of the app sandboxing model and mechanism: apps must declare intention and ask permission from an OS-level boss to accomplish anything dangerous.
Sandboxed Apps vs. Non-Sandboxed Apps
Since June 1st, 2012, all third-party applications distributed through the Mac App Store must be sandboxed. While sandboxing does permit a large range of app functionality, you’ll find that Mac App Store apps are often more limited than their non-sandboxed components. Some developers even maintain two versions: a fully-featured app for direct download and a gimped version for the Mac App Store. Thanks to the greater complexity of sandbox development, adding new functionality to an application is more difficult – if that functionality is even permitted by the OS, that is.
While sandboxed apps can get the benefit of Mac App Store distribution. However, we’ve never wished an app had been in the Mac App Store. That’s more of a curse, perhaps.
Sandboxing can also be extended with security permissions. While an app cannot turn on Accessibility permissions for itself, it can ask the user to do so. Because the app is blocked off from configuring that setting, you could consider Accessibility permissions as outside the app’s sandbox.

To see which of your apps are sandboxed, open Activity Monitor. Then, right-click the column titles to add “Sandbox” to the window.
There are some apps that can simply never exist in a sandbox. In fact, a variety of valuable use cases are prevented by sandboxing. Sandboxing prevents inter-application communication, observation, or modification, significantly limiting how applications can interact. Macos battery saver app. System-wide shortcuts like TextExpander are totally prohibited, since that level of functionality could be permitted by the sandbox.
Is Sandboxing a Good Thing?
While promising, macOS app sandboxing wasn’t executed well. It limited the unique selling points of Mac apps, like speed and enhanced functionality. Apps running outside the sandbox are almost always more capable and faster. From this power user’s perspective, my most-used apps are non-sandboxed. Apps like TextExpander, SnagIt, and TotalFinder are all crucial to my daily work. To avoid similar widespread avoidance, future security systems need flexibility and power balanced with transparency.
