Apple Seeds OS X 10.8.5 Build 12F23 to Developers

Apple today seeded build 12F23 of OS X 10.8.5 to developers, offering a fifth version of the next Mac operating system update for testing. The release comes one week after the appearance of the previous beta of OS X 10.8.5, build 12F20.

As with previous betas, the update comes with no known issues and can be downloaded via Apple's Developer Page or through the software update tool in the Mac App Store.

Testing on OS X 10.8.5 comes as Apple is also continuing work on its next major version of OS X, Mavericks. Apple has already seeded three developer previews of OS X Mavericks and has announced that it will launch the new operating system to the public this fall.

The regularity of these ML seeds is reassuring, considering all the work that must be going on with iOS7 and Mavericks.

I guess this will be the last update for Mountain Lion, good.

Since Snow Leopard I think OS X is not that at it's best, hopefully Mavericks will be more like Snow Leopard performance wise.

What makes you say that? Granted these aren't the days where we'd see 10.x.13, but I don't see why anything would prove us failing to see 10.8.6 in the future.

And why would all that come to OSX with an incremental update of an OS that will be outdated by fall?

Do you know what they will probably fail on doing? Blocking people from posting entire replies using hugely sized bold fonts on forums.

Hopefully if this is the last version of 10.8 they release all of the new hardware BEFORE this so I don't have to support yet another OS so soon... BRING ON THE HASWELL HARDWARE!

I love how people don't remember anymore how buggy and graphically slow Snow Leopard was until 10.6.4 or 10.6.5...

If you want refinement of stability, yearly major releases of an OS are not what you're looking for.

But with 10.8.4 we have come to a point quite near the SL performance. At least for me ML runs smooth - with a whole bunch of additional features that should be considered.


Really, I don't think it's quite there, better than Lion, but not as good as Snow Leopard.

Just plan to try the Mavericks, what is difference between the two versions?


A LOT of under-the-hood improvements, making the system faster and more stable.

Just like Snow Leopard; no new features (or just a few), but a lot of improvements you won't see, but definitely will FEEL! :cool:

Mavericks will be the best release since SL!

Please just release a fix for the stupid EFI bug you introduced in the Retina MacBook Pros that throttles unnecessarily :(

Wow, I'd forgotten 104-6 required a year or more each for beta development. Bertrand Serlet wasn't playing around, he pushed OS X development to its edge and made certain GM releases were stable enough for release (there were a few misfires, however those releases had the most drastic system overhauls and features than most OS X releases).

Before 10.7, beta's were released weekly/bi-weekly and required burning the image and a clean install. This allowed for better debugging as it wasn't an "update" over previous beta's that may have third party app's and poorly executed updates which result in unrelated OS X debugging. The move to an iOS based developer structure with 10.7 seems to be negatively impacting current releases (I've never seen so many unresolved bug reports for fellow developers and AppleSeed invitees). Lowering developer memberships a few hundred dollars to $99 was great, but the subsequent push for yearly releases seems rushed and less than stellar.


I was just saying that judging on past OS X releases I'm not expecting another ML release after 10.8.5

That said, I'm with you on the fact that OS X yearly release is not that good, at least for me, Leopard and Snow Leopard were way better than any other OS X, and that's mainly do to the fact that they lasted almost 2 years.

Unlike iOS, that changes every year do to competition and try to stay fresh and new, OS X shouldn't be that way, I felt that Lion 10.7.4 was pretty good and coming around, then 10.8 came out, so for me that was the end for Lion, now that that ML 10.8.4 is pretty good and probably 10.8.5 will be even better, I won't even use 10.8.5 because 10.9 will be released almost the exact same time, and then again, to star with a new OS and the cycle of star fixing the bugs again.
