Apple Seeds First OS X Mavericks 10.9.5 Beta to Developers

Apple today seeded the first build of OS X 10.9.5 to developers, one month after releasing OS X 10.9.4 to the public. The new beta is available through the Software Update mechanism in the Mac App Store and through the Mac Dev Center. The beta has a build number of 13F7.

10_9_5_13f7
OS X 10.9.5 follows new seeds of Safari 7.0.6 and 6.1.6 for Mavericks and Mountain Lion, which were released to developers last night.

It is unclear what improvements the 10.9.5 update will bring to Mavericks, but it is likely to include bug fixes and stability enhancements. Apple is asking developers to focus on USB, USB Smart Cards, Graphics, and Safari.

Along with working on improvements to Mavericks, Apple is also beta testing OS X Yosemite, which is due to be released in the fall. The last Mavericks update, 10.9.4, added several Wi-Fi fixes and improved wake from sleep reliability.

Will they ever fix the wi-fi issues?

My two uMBP and two rMPBs all sometimes either have no wi-fi after sleep or they do not see the majority of SSIDs in the area.

Good. Mavericks will be the last OS I install on my Macs so I'm all for making it as stable and reliable as possible.


Good luck with that.

I'm excited for this. 10.9.4 has had issues and caused Kernel Panics for me. Also, I'm not sure if I'll update to Yosemite so I look forward to any improvements they can make to Mavericks.

What about Safari 7.1 that was issued to developers?

----------

This is just the last update that will finish off Mavericks making it as finished as it will get. They did in with 10.7.5, and 10.8.5, so make Mavericks the most solid OS possible


I agree. Really the only thing of value in Yosemite for me is iCloud Drive and a better Safari. I think Safari 7.1 will bring improvements, but Apple won't update Mavericks with iCloud Drive to try and push Yosemite. I am at a point now were I don't want to try everything new. I just want a stable and reliable system, so even if I want to update to Yosemite I will wait until 10.10.1

It's really amazing how antiquated Mavericks feels now, after running Yosemite for almost two months. To think Mavericks is still the current system...

I'll probably stick with Mavericks for a long time. I'm just not feeling it with the Yosemite interface.


According to these forums you will be "outdated, stubborn, ignorant, and old fashion." :rolleyes:

P.S: I agree with you, too hard for me to read :D

Here are some of the internal code-names of different Mavericks builds :
- build 10.9.0 : ???
- build 10.9.1 : board
- build 10.9.2 : carve
- build 10.9.3 : ???
- build 10.9.4 : epic
- build 10.9.5 : ???

All three are surfing terms (http://www.surfing-waves.com/surf_talk.htm). According to the pattern emphasized in bold, 10.9.0's code-name must have started with the letter a, 10.9.3's with a d, and 10.9.5 with a f. For 10.9.5's name, I'm betting on "fin" !

Do people reckon Apple will ever get it right with sleep/wake from sleep, and/or wi-fi issues ?

I'm glad they are working on USB issues. I really hope the fix that pesky Disk was not ejected properly notification that pops upon Wake from Sleep.

I'll probably stick with Mavericks for a long time. I'm just not feeling it with the Yosemite interface.

How do the improvements here move over to Yosemite? They exist simultaneously and are two different animals but one is the evolution of the other... So how do they stay in-sync?


They probably start a feature branch for each issue they work on based on 10.9.4. Then depending on the issue, each feature branch will be merged into 10.9.5 and if it's applicable also into the Yosemite branch. Yosemite is an evolution of Mavericks so big parts of the code base is almost identical and easy to merge. Things that's totally rewritten in Yosemite will probably not se merges from Mavericks but if there's known issues that have same solution it will probably be fixed in a fork directly in the Yosemite branch.
