mavericks.pngApple today seeded build 13D33 of OS X 10.9.3 to developers, just under a week after releasing the fourth OS X beta, build 13D28, and a month after the first 10.9.3 beta.

The beta is available through the Software Update mechanism in the Mac App Store as well as through the Mac Dev Center.

Apple continues to ask developers to focus on Graphics Drivers and Audio, and Safari. As was discovered with the first beta, 10.9.3 adds new support for 4K displays, offering “Retina” resolutions that improve readability along with support for 60Hz output from the Retina MacBook Pro.

I still don't get the concept behind retina. If it has to be always scaled down to lower resolutions, then how does it becomes different from a computer that runs the same resolutions (the resolution that the retina is scaled down to) natively ?

Go retina for a month then go back and you'll see.

4x the amount of pixels fill up that resolution, so the display is very clear.

10.10 will be out by the time 10.9.3 is released.

10.10 won't be out until later in the fall. The first seed will likely be available on June 2nd, when the keynote demo is done.

You need to look at the pixel density as the second major factor, not the resolution by itself. It's showing 4 pixels of data in the same area of two pixels on a non-retina display.

Here's what it looks like:



See how sharp the text is on the bottom and how the icon is more detailed. It is because it is showing twice as more details in the same area.

It has to scale down to match the same usable space as the previous screen. If it didn't scale down, it would show the pixels as two smaller pixels, meaning everything will be twice as small than before.

If you haven't, I'd suggest you report the bug to Apple directly (http://www.apple.com/feedback/macosx.html)

That link is only for the public.

These betas are only for developers.

So if you have the beta installed and found a bug assuming you are a developer, you should use apple's bug reporter at this link instead: https://bugreport.apple.com/ to file a proper bug report.

Login with your developer id.

Still no fix for the Auto-detect language check spelling bug. :( Apple broke it in Mavericks and never fixed it...

The bug is if Auto-detect language is on, it does only underline in red only half of the errors on a text. If a word that I know if not correctly written but not underlined in red and I right click on it, it does show me all the alternative words, like it it was underlined. If I only select 1 language in the spelling correction, then all the miswritten words are properly underlined. Since I do write texts in 3 languages, I cannot only select one language for the spelling check.

Please fix it!

If you haven't, I'd suggest you report the bug to Apple directly (http://www.apple.com/feedback/macosx.html) since it's very unlikely their bug list and their priorities come from MacRumors. Note that doing so doesn't mean that it gets fixed any time soon (if ever), as bugs get prioritized and slotted into releases based on resources (people) and severity, but unless it gets reported to them, it doesn't get on their radar.
