Not every Mac user knows that there is a pre-installed utility on their machine that allows them to manually restrict access to the operating system resources. It is called Sandbox.
When to Use Sandbox
With a growing community of over 1 million Sandboxx users, we are continuing to build more products to help.

Delete the Sandbox App. There are two easy ways to delete the Sandbox app. You can drag-and-drop it to the Trash folder or use the Launchpad interface. Drag-and-Drop to the Trash Folder. As with other Mac apps, you can easily drag-and-drop Sandbox to the Trash folder to delete it. Here’s how: Close Sandbox and all other processes related. Many apps that use plug-ins, apps that rejigger aspects of the operating system (some audio recording apps and screencasting tools) and others won't pass muster with Apple, and have no choice but to live outside the Mac App Store environment. Like I said at the outset, sandboxing makes good sense for Apple from a security standpoint. Enter OS X 10.7. With Apple having learned their lesson, SandBox evolves now to no longer depend on the developer to enforce it upon their apps, it is enforced by default. Thing is, Apple enforces the SandBox, even as of today on macOS Mojave, based on an entitlement the applications own, which is com.apple.security.app-sandbox. Feb 7, 2011 6:51 PM in response to Mac OS XI In response to Mac OS XI I'm having a similar issue however I don't recall ever setting up a Sandbox account.
Sandbox is best used when running applications that you don’t trust, such as those that you have downloaded from unverified sources and that require you to execute them even if you haven’t yet verified whether or not they are legit.
It can also be used when a certain app requires access to external websites, triggering you to download more files or content that may corrupt your browser and plugins.
Take note, though, that using Sandbox does not mean you no longer need antivirus software for your Mac. The truth is, it works in conjunction with an antivirus.
Problems with Sandbox
Unfortunately, “Sandbox-ing “apps is not as easy as running a program. It takes several trial-and-error attempts before you can master it. While some apps may crash when Sandboxed, especially when restrictions are applied, others become so corrupted that they no longer work as they should.
Apart from apps crashing and becoming corrupted, another problem that users have encountered when using Sandbox is that they can’t delete Sandbox files on Mac. When trying to delete them, they are greeted with the “Can’t delete ‘.sandbox’ files: com.apple.WebKit.WebContent.Sandbox / com.apple.WebKit.Networking.Sandbox” error message.
The good news is that many have found success in removing Sandbox files. We’ll discuss that below.
How to Remove Sandbox Files on Mac
If you have no idea how to remove Sandbox files, the solutions below could be of great help.
1. Delete the Sandbox App.
There are two easy ways to delete the Sandbox app. You can drag-and-drop it to the Trash folder or use the Launchpad interface.
Drag-and-Drop to the Trash Folder
As with other Mac apps, you can easily drag-and-drop Sandbox to the Trash folder to delete it. Here’s how:
- Close Sandbox and all other processes related to it.
- Open Finder on your Mac.
- In the sidebar, navigate to Applications.
- Look for Sandbox in the list.
- Drag its icon to the Trash folder and drop it there.
- Alternatively, you can right-click on the Sandbox icon and select Move to Trash.
- If prompted, provide your administrator password.
- Hit Ok to proceed.
- Right-click on the Trash icon.
- Select Empty Trash.
Using the Launchpad Interface
https://kjkdnjc.weebly.com/app-not-open-message-on-mac.html. Apps that are preinstalled on your macOS and those that are downloaded from the App store automatically appear under Launchpad. From Launchpad’s interface, you can permanently delete apps that you don’t need or that are wreaking havoc on your system.
Here’s how to delete Sandbox:
- Open Launchpad from the Applications folder or in the Dock.
- Find Sandbox in the list of apps in Launchpad.
- Press and hold the Option key until the Sandbox icon jiggles.
- Click the X button next to Sandbox.
- Hit Delete to confirm your action.
2. Remove Traces of the Sandbox App from Your Mac.
Some Mac users believe that leaving invalid files and folders on their hard drive won’t do any harm to their system. But actually, that depends. In most cases, these files may not consume much space, hence they won’t cause problems. However, it is more practical to get rid of any traces of them, especially if you are going to perform a fresh installation of macOS or if you wish to reclaim valuable disk space.
To remove all traces of the Sandbox app from your Mac, follow these steps:
- Go to Finder.
- Select Go and then click Go to Folder.
- Enter /Library in the text field.
- Hit Enter.
- In the search bar, input Sandbox.
- All files that are associated with the Sandbox app should appear on the screen. Go through each one of them and delete as needed.
- After deleting all files and traces of the Sandbox app from your system, right-click on the Trash folder.
- Select Empty Trash.
3. Install a Trusted Mac Cleaning Tool.
Oftentimes, errors arise due to cache and unnecessary files that have accumulated on your Mac over time. Thus, make it a habit to delete them regularly to prevent them from causing more damage to your system.
Of course, you can delete unnecessary files the manual way. Go through each folder on your system and delete those that you suspect are malware or viruses. But take note that this can be very time-consuming, especially if you have a multitude of folders.

Summary
Apple Sandbox
There is no such thing as a perfect app or tool for Macs. Every now and then, errors surface, which may affect your overall experience and productivity. However, these issues should not keep you from using your Macs. After all, Apple continuously releases updates in an effort to fix common Mac problems and better your experience.
So, the next time you encounter problems with Sandbox, just sit down and relax. Take a deep breath and run through the solutions we have listed above. Everything will be alright.
In my own tests that is something that became apparent.I can remember at the time also being a little annoyed of other changes. But look above at post #7 (pandy).

Mac Os Sandbox Application
3. Vulnerability Description
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. Namely, sending Apple events is possible within the no-network sandbox (kSBXProfileNoNetwork). A compromised application hypothetically restricted by the use of the no-network profile may have access to network resources through the use of Apple events to invoke the execution of other applications not directly restricted by the sandbox.
It is worth mentioning that a similar issue was reported by Charlie Miller in his talk at Black Hat Japan 2008 [2]. He mentioned a few processes sandboxed by default as well as a method to circumvent the protection. Sometime after the talk, Apple modified the mentioned profiles by restricting the use of Apple events but did not modify the generic profiles.
4. Vulnerable packages
- Apple Mac OS X 10.7.x
- Apple Mac OS X 10.6.x
- Apple Mac OS X 10.5.x

This vulnerability was discovered and researched by Anibal Sacco and Matias Eissler from Core Security Technologies. The publication of this advisory was coordinated by Carlos Sarraute.
8. Technical Description / Proof of Concept Code
The use of Apple events is possible within the several default profiles as no-network, no-internet (kSBXProfileNoNetwork, kSBXProfileNoInternet) and others. A compromised application hypothetically restricted by the use of the no-network profile may have access to network resources through the use of Apple events to invoke the execution of other applications not directly restricted by the sandbox.
As Apple's 'App Sandbox Design Guide' document points out, applications that require sending Apple events to other arbitrary applications are not suitable for sandboxing, because some developer tools restrict Apple events by default while defining the sandbox. The reason for this is that, as we show here, by dispatching Apple events a process can escape the sandbox [1].
The method used by Charlie Miller involves dropping a script to the disk and getting it executed by launchd via launchctl. Our approach is technically the same without the need to drop a file. In our PoC we used 'osascript' to send the required Apple events to launchd in order to execute the new process. As the new process is not a 'child' of the sandboxed process, it is created without the sandbox restrictions.
An additional risk with these profiles is that they are supposed to provide an example of how a process should be restricted in different scenarios. If the no-network profile allows Apple-script events, this may result in new applications using the same restriction rules, therefore offering a false sense of security.
The following PoC illustrates this vulnerability:
9. Report Timeline
- 2011-09-20: Core Security Technologies notifies Apple Product Security of the vulnerability, including technical details. Preliminary publication date is set to November 7, 2011.
- 2010-09-20: Vendor acknowledges the receipt of the information.
- 2010-10-05: Vendor informs that it does not see any actual security implications. The kSBXProfileNoNetwork sandbox profile does not promise that Apple Events will be blocked in the documentation. (Specifically, all it guarantees is 'all sockets-based networking is prohibited'.)
- 2011-10-13: Core responds that the kSBXProfileNoNetwork sandbox profile should guarantee that 'all sockets-based networking is prohibited'. The PoC sent to Apple shows that through the use of Apple events (osascript is used in the PoC just to keep it simple) an attacker could circumvent the restriction. So, at the end, sockets-based networking is used.
- 2010-10-18: Vendor responds that it is currently considering modifying its documentation to explicitly point out what Core described; namely, that the restrictions that these particular sandbox profiles provide are limited to the process in which the sandbox is applied.
- 2011-11-10: The advisory CORE-2011-0919 is published as user release.
