Today’s process, sandboxd, is a daemon, which means it runs a system task in the background on macOS-daemons generally have a “d” at the end of their name. Don’t know what those services are? Better start reading! This article is part of our ongoing series explaining various processes found in Activity Monitor, like kernel_task, hidd, mdsworker, installd, WindowServer, blued, launchd, backup, opendirectoryd, powerd, coreauthd, configd, mdnsresponder, UserEventAgent, nsurlstoraged, commerce, parentalcontrold, and many others. RELATED: What Is This Process and Why Is It Running on My Mac? Working together, these prevent an app from accessing more of the system than is necessary to get its job done.You noticed something called “sandboxd” while looking through Activity Monitor, and now you’re here. The elements of App Sandbox are entitlements, container directories, user-determined permissions, privilege separation, and kernel enforcement.
On the other hand, a sandboxed app has access to the specific resources you request, allows users to expand the sandbox by performing typical actions in the usual way (such as drag and drop), and can automatically perform many additional actions deemed safe, including:
If you are writing a sketch app, for example, and you know your app will never need access to the microphone, you simply don’t ask for access, and the system knows to reject any attempt your (perhaps compromised) app makes to use it. User Files (Downloads, Pictures, Music, Movies, User Selected Files)Īccess to any resource not explicitly requested in the project definition is rejected by the system at run time. Network Connections (Inbound or Outbound) Hardware (Camera, Microphone, USB, Printer) For example, a sandboxed app must explicitly state its intent to use any of the following resources using entitlements: App Sandbox is Based on a Few Straightforward Principlesīy limiting access to sensitive resources on a per-app basis, App Sandbox provides a last line of defense against the theft, corruption, or deletion of user data, or the hijacking of system hardware, if an attacker successfully exploits security holes in your app. But the scope of potential damage is severely limited when an app is restricted to the minimum set of privileges it needs to get its job done. Apps can still be compromised, and a compromised app can still do damage. The system then grants your app the access it needs to get its job done, and no more.Īpp Sandbox allows the user to transparently grant your app additional access by way of Open and Save dialogs, drag and drop, and other familiar user interactions.Īpp Sandbox is not a silver bullet. If that app or any framework it is linked against contain security holes, an attacker can potentially exploit those holes to take control of that app, and in doing so, the attacker gains the ability to do anything that the user can do.ĭesigned to mitigate this problem, the App Sandbox strategy is twofold:Īpp Sandbox enables you to describe how your app interacts with the system.

While App Sandbox doesn’t prevent attacks against your app, it does minimize the harm a successful one can cause.Ī non-sandboxed app has the full rights of the user who is running that app, and can access any resources that the user can access. No matter how carefully you adopt secure coding practices and guard against bugs, attackers only need to get through your defenses once to succeed.

Apple sandbox mac#
Apps signed and distributed outside of the Mac App Store with Developer ID can (and in most cases should) use App Sandbox as well. Apps distributed through the Mac App Store must adopt App Sandbox. It is designed to contain damage to the system and the user’s data if an app becomes compromised. App Sandbox is an access control technology provided in macOS, enforced at the kernel level.
