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

At a Glance

Complex systems will always have vulnerabilities, and software complexity only increases over time. No matter how carefully you adopt secure coding practices and guard against bugs, attackers only need to get through your defenses once to succeed. While App Sandbox doesn't prevent attacks against your app, it does minimize the harm a successful one can cause.

A 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. 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.

Designed to mitigate this problem, the App Sandbox strategy is twofold:

  1. App Sandbox enables you to describe how your app interacts with the system. The system then grants your app the access it needs to get its job done, and no more.

  2. App 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.

App Sandbox is not a silver bullet. Apps can still be compromised, and a compromised app can still do damage. 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.

App Sandbox is Based on a Few Straightforward Principles

By 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. For example, a sandboxed app must explicitly state its intent to use any of the following resources using entitlements:

  • Hardware (Camera, Microphone, USB, Printer)

  • Network Connections (Inbound or Outbound)

  • App Data (Calendar, Location, Contacts)

  • User Files (Downloads, Pictures, Music, Movies, User Selected Files)

Access to any resource not explicitly requested in the project definition is rejected by the system at run time. 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.

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:

  • Invoking Services from the Services menu

  • Reading most world readable system files

  • Opening files chosen by the user

The elements of App Sandbox are entitlements, container directories, user-determined permissions, privilege separation, and kernel enforcement. Working together, these prevent an app from accessing more of the system than is necessary to get its job done.

Design Your Apps with App Sandbox in Mind

After you understand the basics, look at your app in light of this security technology. First, determine if your app is suitable for sandboxing. (Most apps are.) Then resolve any API incompatibilities and determine which entitlements you need. Finally, consider applying privilege separation to maximize the defensive value of App Sandbox.

Xcode Helps You Migrate an Existing App to App Sandbox

The Boxing Room Mac OS

Some file system locations that your app uses are different when you adopt App Sandbox. In particular, you gain a container directory to be used for app support files, databases, caches, and other files apart from user documents. Xcode and macOS support migration of files from their legacy locations to your container.

Preflight Your App Before Distribution

After you have adopted App Sandbox in your app, as a last step each time you distribute it, double check that you are following best practices.

How to Use This Document

To get up and running with App Sandbox, perform the tutorial in App Sandbox Quick Start. Before sandboxing an app you intend to distribute, be sure you understand App Sandbox in Depth. When you're ready to start sandboxing a new app, or to convert an existing app to adopt App Sandbox, read Designing for App Sandbox. If you're providing a new, sandboxed version of your app to users already running a version that is not sandboxed, read Migrating an App to a Sandbox. Finally, before distributing your app, work through the App Sandbox Checklist to verify that you are following best practices for App Sandbox.

Prerequisites

Before you read this document, make sure you understand the overall macOS development process by reading Mac App Programming Guide.

See Also

To complement the damage containment provided by App Sandbox, you must provide a first line of defense by adopting secure coding practices throughout your app. To learn how, read Security Overview and Secure Coding Guide.

An important step in adopting App Sandbox is requesting entitlements for your app. For details on all the available entitlements, see Entitlement Key Reference.

You can enhance the benefits of App Sandbox in a full-featured app by implementing privilege separation. You do this using XPC, a macOS implementation of interprocess communication. To learn the details of using XPC, read Daemons and Services Programming Guide.

It's time for another chipset transition for the Mac, this time from Intel to ARM. Apple announced their transition to Apple Silicon during WWDC 2020 and they aim to be finished within two years. This page shows the rumors leading up to the announcement of the official transition.

● Custom Apple Silicon
● New ARM friendly macOS Big Sur
● Based on existing A-series processors
● Software already exists
● Control over entire stack
● Leave legacy software behind
● Apple Developer Transition Kit

The Boxing Room Mac Os Catalina

Pre-WWDC 2020 page: Go to Apple Silicon for information about Apple's transition plan and their custom processors. This page will remain for reference to rumors and leaks leading up to the announcement.

Software shifts and hardware transitions are nothing new to Apple, and we are about to see another huge shift in how they approach consumer technology. Until now, the Mac has relied on innovation and development from Intel to move forward, but with the ARM Mac, Apple will have total control.

Apple produces its own ARM chipsets for iPhone and iPad, and may do the same for its ARM Mac

Rumors have circulated for a few years now about the potential of an ARM-based Mac. With the introduction of the iPad Pro and continued year-over-year improvements to Apple's A-series chipsets, an ARM Mac feels almost inevitable.

The past decade has been bumpy for Mac users. Apple has had its own host of issues with designs they introduced, like the butterfly keyboard and cylindrical Mac Pro, but much of what has been holding back the Mac falls on Intel.

Since 2015 Intel has seen marginal improvements in their chipset capabilities and relied upon increased clock speeds and more demands on cooling than actual processor gains. This left Apple with little room to move when it came to innovating on the Mac platform.

Apple even had to implement custom silicon in their Macs to run in tandem with the Intel processors, thus taking some of the load off of the Intel processes.

The T1 was Apple's first ARM chip in a Mac; used for improved security

If Apple controlled the development of all the hardware and software in Mac, just as it has with the iPhone and iPad, then we would see much greater leaps in performance over time. This would allow more room for innovations in design and add in additional use cases and hardware.

Since the release of macOS Catalina, we have seen a slow trickle of Mac Catalyst apps. These are apps designed for iPad that have been formatted to work on Macs with macOS system architecture and Intel chipsets.

While Catalyst has yet to prove a great hit with developers, it lays the groundwork necessary for them to start programming iPad apps as if they were running in a macOS environment.

It is safe to assume that Mac Catalyst developed iPad apps will be easily transitioned, if not directly portable, to an ARM Mac. Catalyst also shows that Apple is capable and learning about making it easy to implement developer tools for transitions between platforms.

Do not be surprised if we see a 'Mac Catalyst ARM edition' of some kind very soon.

Perhaps the most crucial development surrounding software for the ARM Mac is SwiftUI. This new language is universal and can easily be used for any Apple Platform during development.

In 2005, late Apple CEO Steve Jobs announced that the Mac would transition to Intel from PowerPC over a year starting in 2006. The entire Mac line transitioned to Intel processors in 2006, first ones in January, and the last in August. Mac OS X Snow Leopard launched in 2009 as Intel only.

To move the entirety of the Mac platform for millions of users, minuscule by today's user base, to a new system architecture with minimal issues was an incredible feat. It is impossible to determine the speed at which Apple will move Mac to ARM, but for everyday users, the transition will likely be invisible.

Today's ARM chipsets can already handle most tasks an average user performs, and not having compatibility with Windows shouldn't be an issue in a world where most data is in the cloud anyway. We do not know what kind of performance an Apple-designed 'desktop-class' ARM chipset will produce, but it may be a few generations before the Mac Pro can kick Intel entirely. Lesser Macs meant for consumers and professionals who are not mapping star systems or making a Pixar movie will likely be just fine with ARM.

The iPad Pro with the A12X chipset operates better than many consumer PCs and laptops, how will the ARM Mac perform?

Apple tends to be obsessive about consistency across a platform. It is hard to imagine Apple having their entire product line from iPod to iMac running on ARM and having one single Mac on Intel. This would lead to software compatibility issues and development forks in professional-grade tools.

Even with the entire line shifting to ARM, leaving the Mac Pro as is during the transition will work fine. When you do see a Mac Pro with Apple ARM inside, expect macOS to deprecate Intel Macs soon after.

Unless you are a professional who needs to run Windows and macOS on the same machine, or have very specific software that won't update to the new ARM architecture for a few years, you won't even notice this is happening. The biggest change for more casual users will be the lockdown of compatible software.

All of the software a user downloads from the web assumes they are working on a Mac or PC running Intel. This means when you buy an ARM Mac, you will not be downloading any of that software, which might be frustrating for users. iPad and iPhone cannot download apps from the web, and the same could easily occur for the ARM Mac.

The MacBook Air is a great candidate to become an ARM Mac since its small size restricts it from more powerful chipsets

Since macOS has a bit more control over software installation, Apple will likely enable settings for users to install compatible applications from the web. It will be up to third-party developers to make their software compatible, however, and could mean a minimal third-party software for some time after launch.

If Apple is serious about an ARM transition, it will have to be behind developers all the way, and incentivize them to develop apps quickly.

If Apple restricts Mac software to the Mac App Store or makes it very hard to install from anywhere else, developers will need to offer their apps through official Apple channels. Otherwise, Apple could alienate popular developers and thus lose customers to Windows because of a lack of compatible software.

Another issue that is easily solved with licensing is Thunderbolt. Intel owns the rights to Thunderbolt and includes the necessary I/O for the ports in the Intel chipsets. Unless Apple comes up with its own version of Thunderbolt without violating patents, Apple will likely still be in business with Intel in some capacity.

Rumors point to the fall of 2020 for the first ARM Mac. The now-defunct 12-inch MacBook would make the perfect candidate for the first Mac with Apple ARM inside. Some speculate a return to the 'iBook' branding for such a device since it would essentially be a MacBook running on iPad chipsets.

Reputable analyst Ming-Chi Kuo suggests a spring 2021 launch is more likely, repeatedly. Whichever is true, WWDC 2020 is the last chance for Apple to talk directly to developers about such a transition before it occurs, if it occurs before next year's WWDC.

To complicate things even further, WWDC will be held remotely via the internet in 2020 amid coronavirus concerns, making the transition announcement somewhat cumbersome as no developers will be physically present.

A developer transition kit is needed, and software too, because the hardware cannot launch without any software. It is likely that an official announcement from Apple is not far off. One Twitter leaker suggests there is a 12-inch device in development at this moment, and another leaker has since followed up stating the 12-inch ARM MacBook could be the first such product.

Another rumor corroborated the existence of a device, suggesting an ARM Mac laptop of some kind would be seen sometime in 2021. This device would host a version of the upcoming A14 chipset that is slated for the 'iPhone 12.'

Just before WWDC, Kuo released another note stating there would be an ARM MacBook by the end of 2020, with a 24-inch ARM iMac to follow.
