Apple Seeds OS X Mavericks 10.9.5 Build 13F14 to Developers

by

Apple today seeded Mavericks 10.9.5 build 13F14 to developers, just over a week after seeding the second OS X 10.9.5 beta, build 13F12, 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, and Thunderbolt.

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.

As if anybody truly cares about Mavericks at this point

Plenty of people do, for some people it makes sense to update quickly but for others there are good reasons to stay on the last version for a length of time.

I'm excited about 10.10 but also very glad to see more work done on 10.9.

Yes because your feelings represent everyone else's. I use my Mac for work. Which means the software I'm using needs to be in working order. I wait A LONG time before I update to a new os because if something doesn't work, I'm ****ed. So the fact that Apple is continuing on making 10.9 better is welcome to a lot of users.

What's wrong with you? Why do you think that you speak for everyone?

Many people wait quite some time after a new OS is released. Do you know why? Do I need to explain it to you? Let me know if you want an explanation or if you have enough thinking power left to figure it out for yourself.

Yeah well friends of mine that actually make money with their Macs are prohibited by me to jump directly on the new OS X. So yes, 10.9.5 is welcome, it will be a while before Yosemite will be ready for prime time.

Are you sure you don't have any view options set in the Finder that could slow things down? Such as ”Calculate All Sizes”. It doesn't seem that slow to me to display contents of folders in column view. More or less instant.
Column view doesn't actually have "Calculate All Sizes" (I only browse in column view but I've never had this issue).

Finder is not garbage, and its spelled Mac, not MAC. Its a personal computer called Macintosh shorted to Mac, not Media Access Control.
It's spelled it's not its. It's a contraction of "it is" not the possessive form of it. :p
