Tech limits reach of apps
Apple has announced an extension on implementing sandboxing for Mac App Store titles. Developers were originally expected to have changes finished by March 1st, but the new deadline is now a full three months later, on June 1st. The technology is already present in OS X 10.7.3 as well as Xcode 4.3 APIs.
Sandboxing controls a program's access within an operating system, in theory limiting the amount of damage it can do when hijacked by malware. Apple's implementation has been criticized by some developers as restricting their work, while security specialists have suggested that it has vulnerabilities. In any case, Apple has had to delay standardizing sandboxing multiple times.
The original goal was to make the technology standard at the launch of the Mac App Store, in January 2011. Instead a November 1st date had to be set, but even that deadline was later extended to the March 1st target. What problems Apple might be having are unclear.
