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.
