Apple Seeds OS X Mavericks 10.9.5 Build 13F24 to Developers

Apple today seeded Mavericks 10.9.5 build 13F24 to developers, just over a week after seeding the fourth OS X 10.9.5 beta, build 13F18, and more than a month after releasing OS X 10.9.4 to the public.

The beta is available through the Software Update mechanism in the Mac App Store and through the Mac Developer Center.

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, Safari, Thunderbolt, and Gatekeeper.

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.

I'm really looking forward release. I just hope it will fix USB "External Disk was not Ejected Properly" error.

i'm dreadfully looking forward to this update, as well. i hope "stability fixes" include NVRM/Read Error/GPUPanic Kernel Panic issues associated with Mid-2010 MBP's w/ the Nvidia GT330m.

I will be holding my breath.


Nope... that is hardware issue...

You do now, but not in about two months.



Anyone still on the BEST Mac OS X Snow Leopard..?:rolleyes:


I just upgraded from Snow Leopards a few months ago. I had no use of any of the features of Mavericks. As it stands I spend several days disabling the most annoying things like AutoSave, Versions and Message Center.

It was the simple fact that Apple stopped to issue security updates for the OS that forced me to switch. I am not looking forward to switch OS again soon...

I still prefer Mavericks as an environment


As do I. It'll be months or perhaps longer before I'll move from Mavericks. 10.10 will be matured when I go all in.

Nope, that requires the user (you) to stop pulling the plug on the External Disk without first unmounting the volume from the file system. :p


You need to do a little more research. Many! People are having this problem. Also, don't Assume so much. My drives are NEVER unplugged.

It's a common problem.

I have this error occurring repeatedly with a USB3 disk enclosure and it is not because of "pulling the plug" - the drive will randomly disconnect when attempting to write data to the disk.

Randomly in the sense that it can write 2GB of data, then disconnect, OR on another attempt, it will write about 500MB of data then disconnect.

Please put a little effort into the speed of the finder over SMB connections. Simplify it or give us the ability to put it into a "light" mode.

Finder is bloated and has too many things happening in the background.

Finder over VPN is not even usable, even on fast connections to any flavor of SMB server.

Is this definitely a hardware issue? I've seen this sort of thing (specifically the display stopping working and "NVDA channel timeout" messages appearing in the log) start happening on a mid-2010 13-inch MacBook Pro (GT320M graphics) only after it was upgraded to Mavericks. It was previously running 10.6.8 without a problem.


I had the same kernel panic problem when I upgraded from Snow Leopard to Mavericks. Initially I suspected Mavericks graphics error and filed a bug report to Apple. They got back to me by saying that my MBP has an open issue, which was supposedly rectified via a software update applicable from SL up till ML, but no solution on Mavericks.

Initially kernel panic when I use Mission Control with Microsoft Word active, but overtime the symptoms got worse. At this juncture my MBP was already 4 years old. Eventually I had to make some noise until Apple agreed to replace the entire logic board for free.

I would say it's a combination of hardware, and bad programming on Mavericks.

I wholeheartedly agree with this. The Finder is a very neglected application on OS X. Puzzles me how it passes Apple's super high standards.
