According to reports, at the beginning of the 10th, Apple released the OS X 10.9 Mavericks GM download to the developer. The version number is 13A598. Now the system version number is quietly upgraded to 13A603. According to Apple's practice, under normal circumstances once the system GM, its version identification number will rarely change, this situation has only appeared when iOS was released.
According to 9to5Mac, this upgrade is only for new users who have installed Mavericks for the first time, and does not support direct upgrade through the developer portal or software updates. It is not yet clear why Apple will create a GM version with a different version number. Apple has not released an update log for this version. It is presumed that this may be just a minor bug fix.
According to the latest news, Apple will release the official version of OS X 10.9 for ordinary consumers at 1 a.m. Beijing time on the 23rd, along with updates on products such as MBP and Mac Pro.
