Since 2012, all apps on the Mac App Store must run in an app sandbox, which restricts access to system resources unless explicitly Withered mac os. required. The secure sandbox isolates the app and defines access controls, protecting users from malicious code with undesired behaviour.
Here's how to setup a sandbox for an app downloaded from outside the Mac App Store.
In my case, I wanted to test out Kodi v17.0 'Krypton' Release Candidate 4 (previously XBMC), an open-source, cross-platform media centre software. I also installed a Kodi Add-on from an 'untrusted source,' which sounds dangerous, doesn't it? Realmrush mac os.
Enter, sandbox! My goal was to prevent Kodi from reading my files, and writing files in locations I did not expect. This goes a long way to securing the system but does not guarantee that you are 'protected'!
Information on sandboxing is rather sparse, but I found two great sources:
- Paolo Fabio Zaino's Blog - How to run your Applications in a Mac OS X sandbox to enhance security and Maximum security and privacy using Mac OS sandbox and Tor browser bundle
- Mozilla's Sandbox OS/X rule set with a detailed Apple's Sandbox Guide v1.0 PDF

The App Sandbox is an access control technology built into macOS (enforced at the kernel level) that provides a twofold strategy: The App Sandbox enables the developer to describe how an application will interact with the OS and, in this way, it is granted only the access rights that are required to get the job done, and no more.

Also, your mac also comes with pre-configured sandbox rules found in /usr/share/sandbox/ which are good starting points.

To run an app sandboxed, first create a file with the set of rules to permit or deny access to system resources, e.g. file system, network, audio, etc. Born punk kickstarter demo mac os.

Now, instead of running the application directly, run it via Terminal:
Finally, to create a 'shortcut' to sandbox-exec that can be quickly run from Finder / Spotlight, create a file called kodi.command as below. The individual commands can be concatinated into a single line, or you can maintain the line breaks for readability:

- Initially, deny all access,
- Run Kodi (which would inevitably fail), and:
- Inspect the console output,
- Inspect the Kodi log files and via Console,
- And also view the open files and ports in Activity Monitor (screen shot below).
- Add individual
allowpermissions one at a time, until I get the functionality I expect.

I didn't test everything, and I intentionally did not want Kodi to access my filesystem. You might want to change this behaviour, e.g. add your movies and music folders. I also see Kodi is trying to access /Users/[[username]]/Library/Saved Application State/org.xbmc.kodi.savedState/ but I was simply too lazy to add it.
Sandbox Rules
To briefly explain the rules:
deny default- deny everything by default.allow network- allows network access.allow iokit-open- access to device drivers, required for Core Image and OpenGL.allow file-read-metadata- without which, no ability to list directories (ls).allow mach* sysctl-read- to get to system info in read mode.(allow ipc-posix-shm (ipc-posix-name-regex '^AudioIO'))- it took me the longest time to enable audio, turns out AudioIO is implemented using shared memory.(allow process-exec (regex '/Applications/Kodi.app'))- allow the Kodi process, and any child processes, to run.(allow file-read-data (literal '/dev/urandom'))- to avoid the errorError in GnuTLS initialization: Failed to acquire random data, configured to be an exact match (literal, compare withregexbelow).(allow file-read-data (regex. - read access to system library files and the Kodi.app contents itself:- The regex pattern
^means 'starting with' i.e. allow read only access to files and folders starting with/System/Library/. - You can add other folders here, e.g.
'^/usr/lib/.*.dylib$'to access user libraries. The$means 'ending with' and is an example of being explicit! - Or the movies, music and
org.xbmc.kodi.savedStatefolders mentioned above.
- The regex pattern
(allow file-write* file-read-data (regex. - allow write access to:Logsfolder.Application Supportwhere add-ons, preferences and databases are stored.
Conclusion
MacOS has an extremely granular sandboxing capability, courtesy of BSD, and is enabled by default for apps from the Mac App Store.
Sandbox 31 Mac Os X
However, to sandbox any other application, it's rather involved and poorly documented. I hope the simplified explanation and sample rules above help you. Hippodrome casino review.
Updated 9 Feb: allow read access to /usr/share/zoneinfo for the time to be displayed correctly based on the configured time zone.
Sandbox 31 Mac Os Catalina
Update 4 Mar: use sandbox-exec -p profile-string instead, to avoid the dependency on an external .sb file.
Mac Os Download
Bad reception mac os. Update 26 Mar: fixed a small 'bug' where I refer to sandbox_exec instead of sandbox-exec.
