Apple(s AAPL) has pushed back, for the second time, the date by which all apps submitted to the App Store must be sandboxed in OS X. While the original deadline was moved from Nov. 1, 2011, to March 1, it has now been pushed forward again to June 1. Sandboxing, a security measure that isolates applications from the rest of the systen they’re running on, has been a controversial measure because it imposes rather strict limitations on what Mac software is allowed to do that runs against long-held traditions.
The delay itself has been greeted with mostly positive reactions from developers, who are thankful for the additional time to adapt to this new approach even if they are still anxious about the long-term implications. Chris Foresman wrote a great summary of sandboxing, Daniel Jalkut of Red Sweater Software covered some of the issues that face developers of Mac software, and Manton Reece, developer of Clipstart, explained why he is dropping out of the Mac App Store to avoid sandboxing entirely. Most discussion of sandboxing has focused on the security implications of the new approach. However, I think that Apple may be playing a long game here that goes far beyond incremental improvements to the security of OS X.
