In most cases developers will just need to implement the entitlements and be done however, in some instances novel approaches to programming and system access may need to be reworked so they will function properly within the rule set. At the very worst, removing this container will force the program to rebuild its resources from scratch, which was recently a solution for Preview not being able to send PDF documents to Mail at a user's request. With sandboxed applications, all of these files for an application are stored in a separate directory called a "container," which is located in the Containers folder within the user library. Many times when programs act oddly it's because caches, databases, and preference files for the program have become corrupted. Luckily, sandboxing means that troubleshooting problems for a sandboxed application will be easier to do for the user. While these problems are likely to happen here and there, they are just bugs that will likely be fixed once found, as opposed to being a long-term issue. We have seen with Safari showing block-A characters when rendering Web pages for some users when Safari's sandboxing prevented interaction with font management tools, and more recently corruption in sandbox containers preventing Preview from sending PDF documents to Mail. In addition to restrictions on program features, there may also be some potential bugs and conflicts with sandboxing that may impact a user's experience. What sandboxing means for user experienceįor the user, sandboxing should be completely transparent with the exception that some applications may lose a function or two, or require a little more interaction from the user for certain tasks. The developer can add as many entitlements as he wishes to give his program as much system access as is necessary however, the idea is the developer only enables the entitlements that are needed to allow his program to run. The entitlements are managed by Apple, and thereby allow Apple to centralize how sandboxed programs can access resources in OS X. To then meet the program's needs, the developer includes a sandbox rule called an "entitlement," that allows the program to access the needed resource defined in that entitlement. When enabled, the program will by default have no access to the system resources, including the network, user documents, the ability to open and save files, access to peripherals such as printers and cameras, and access to locations, address books, calendars, and similar central services. The system cannot do this itself, so the developer voluntarily turns on sandboxing for its program. The way this works is a virtual barrier called a "sandbox" is set up around a running program that isolates it from the rest of the system. Sandboxing is a security technique that acts as a last line of defense against exploited, buggy, or otherwise compromised applications, which Apple is implementing to ensure programs distributed through the Mac App Store are as safe and secure as possible.
