Fifth OS X 10.9.5 beta goes out to developers

updated 03:20 pm EDT, Wed August 27, 2014

Testing continues slow advance

A little over a week after the last one, Apple has issued a new beta of OS X 10.9.5 to developers. The code is identified as build 13F24. Areas of testing focus remain unchanged, and include Safari, graphics, Thunderbolt support, and USB/USB smart cards.

Registered developers can download the beta via the Mac App Store. At this stage, it's unclear how close Apple is to pushing out the final version of 10.9.5 to the public.

    I don't see the point in having another version of 10.9. one month before it will be replaced by Yosemite. If the information is right, those who have Mavericks will be able to upgrade to Yosemite. So, what's the point in wasting resources for a almost dead os? Am I missing something?

    Yes. Many of us professional users may not be able or willing to upgrade until many months from now. Some software may even be permanently broken and never get fixed/certified for the new OS by the developer, forcing us to stick with 10.9 until a suitable replacement is found (if ever).

    OS upgrades are never that simple and are a major disruption for those depending upon computers for a living.

    In the meantime, we appreciate bugs getting fixed and security holes getting patched.

    mojkarma, do you think it would be a good move by Apple to immediately stop updating the preceding OS once a new OS is released? They're already one of the most aggressive companies in dropping support for older software and hardware, and now you want them to be even more aggressive about it?

    If they did that, they would be the sole operating system to do so -- all other operating systems maintain support and updates for preceding operating systems going back some number of years or versions.

    As it stands, people still get miffed about Apple's aggressive update/upgrade cycle and how quickly they drop support for older operating systems and hardware. One common sentiment is, "Look at Microsoft and how they supported and updated XP even three OS revisions and 10 years later! How come Apple can't support [insert 3-year-old-OS here] anymore?!"

    I'm certainly not against the support of the existing/old OS. Yes, I could like everybody else probably write books about how things just stop working because of Apples more than aggressive upgrade cycle. I was just curious that they update an os one month before it gets obsolete.

    Perhaps because it is one month before it becomes obsolete. ie - it is not obsolete yet, so deserves updates until Yosemite is out.

    Following that reasoning, Apple should refuse full support for their current OS version at times.

    Despite the hue and cry of those with axes to grind, Apple does in fact support its OS versions for three revisions back, regardless of how many years apart they are.

    We are in a time where OS X versions come out roughly every year, and thus consequently the "time to unsupported" may have shortened (only it didn't really; Apple supported Snow Leopard for four years).

    The currently supported OS versions (meaning they get every new update) are Lion, Mountain Lion, and Mavericks. I expect there will be a short period where Apple will continue to support Lion even though Yosemite will be out, but beyond that it will be Mountain Lion and higher by this time next summer.
