OS X Mavericks, the much awaited operating system from Apple is to be made public this week at an event to be held at San Francisco. That is the general belief as of now. Also, none perhaps were expecting Apple to come up with an update to the Gold Master version of the operating system so close to the official launch though that is just what has happened. That the OS went in for some last minute changes is what the developers who had received the trial copy has reported about.
The exact reason for the changes which Apple is effecting on their Maverick is not known. Usually Apple does not follow such a process of effecting changes at this stage of the release of their software. That is unless the bug is such that it could affect the upgrading process itself. It should not be construed that there are major flaws in the Maverick which Apple is trying to set right with the new update for Apple gets to the GM build stage only after extensive testing of their software. Apple does have the track record of providing clean updates and maybe it is just a reassuring run that they are conducting on their Maverick before they release it to the public.
The build number has been changed from 13A598 to 13A603, which marks a subtle change though not quite for the eagle eyed Mark Gurman of 9to5Mac. What this means is that the previous flavor of the Maverick is undergoing some change for sure and a new one is going to be rolled out to the people when it does. Up-graders would therefore get the new build and not the one which had been rolled out for the developers earlier.
Most importantly, users can expect the Maverick to be announced on Tuesday by Apple and soon thereafter be rolled out to the people at large.
