A "bug" in the Mac App Store that allows the newly installed OS X 10.9 Mavericks to upgrade ilife, iwork, and other Apple software free of charge. Soon, Apple also learned the "bug". But you don't have to worry about Apple blocking the loophole because Apple says it's not a bug.
Apple explains new ways to update Mac software
Apple insiders told the media: "We did not publish new aperture, iwork and ilife on the Apple website's ' support ' page, nor pushed to ' software update ', for a reason, not a coincidence. Starting with OS X Mavericks, we've changed the way we update our software.
"We are no longer providing updates on every single software in the Mac App store. "Apple decided not to use the software update system anymore. "When OS X Mavericks is installed, it will automatically recognize the software that is installed on your Mac and then use your Apple ID to prepare your Mac APP store for purchase." This saves us a lot of time, effort and bandwidth. Once the preparation is complete, the software will appear in your Mac App Store purchase history as if you had purchased it yourself from the Mac App Store. ”
As for the Pirates and trial version of the user can upgrade the matter free of charge, Apple said: "We also notice that this way will lead to piracy free upgrade, in fact, Apple has not taken a very strong action on piracy." We are willing to believe that our users are honest and trustworthy, although the light we believe is useless. ”
In a sense, Apple does offer ilife and iwork free of charge, but Apple has made it clear that it is for the new iOS and OS X devices.
