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.

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.

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.

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'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

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According to these forums you will be "outdated, stubborn, ignorant, and old fashion."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