Can someone confirm, that 4k/60hz works with the 15'' Iris Pro model? Only the 750m model seems to fully support 4k/60hz under 10.9.3 and Windows 8.1. Friend of mine asked me for help to decide which model he should get. 30hz would be a deal breaker for the base model.
Got a tip for us?

Higher Bit Depth
I was hoping that 10.9.3, and the improved support for 4K monitors, would bring higher bit depths. I remember, when I was a kid, being really excited about 8-bits per channel 24-bit/32-bit color in the mid 90s. It would be funny, if it weren't so depressing and backward, that we've seen no practical improvement in the last 20 years on colour depth on Macintosh. (Yes, I know that there is support for 48-bit output to printers)
The hoops I have to jump through on my workflow for lack of 10-bit / 12-bit / 16-bit per channel output to my display are very irritating.
I'd like 10-bits per channel to drive current day hardware. I'd love to see 16-bits per channel 64-bit color support in OS X, even though there may be no hardware that supports that yet.

Achtung!
tl;dr: Dont sign into iCloud at the end of the 10.9.3 update unless you already have all iCloud syncing turned on.
Just installed 10.9.3 and other updates. Went fine, except - at the end of the updates, it asked me to sign into iCloud again. Ok, I thought, I was already signed into iCloud; just a confirmation
Not! It turned on all the cloud syncing I had turned off (Calendars, Reminders, Docs, Safari bookmarks) and while it was relatively easy to revert, it was frustrating that Apple UI "Experts" thought this would be a good idea. It effed up my Safari bookmarks, but fortunately - XMarks to the rescue!

FWIW, in my brief time with 10.9.3 last night, the wifi issue seemed to be better. Maill was working as well. Fingers crossed it stays that way.
I disagree - Seems to me they are introducing more bugs in every iteration
Wifi issue, kernel panics .
Nope. I gave up and went back to Mountain Lion .I think I am going to have major pain with the Aperture library lets see .
Yes, or at least it fixed my PA301W, which did not sleep correctly on 10.9.2. I ran 10.9.1 until yesterday's update, just for this reason.
I'm curious as to why you require this.
The purpose of color bit-depths above 8 is to prevent data loss when processing images. The image processing software uses 16 bits internally so that rounding errors don't degrade quality.
However, for displaying on the screen, 8 bits per channel is more than enough to depict photographic quality. If your software is doing things right, it will be doing internal processing at > 8 bits per channel, but displaying on the screen at 8 bits per channel without reducing the quality of your work.
The reason we went so quickly from 8 bits total to 16 bits total to 24/32 bits was because there were obvious quality gains from doing so. Display bit depths above 8 don't really improve quality noticeably, so nobody has clamored for them. Heck, many flat panels are still < 8 bits per channel internally and most people don't notice (though I do).
Sorry I don't mean to come across as rude but your memory seems a bit short. The Finder window swiping on the trackpad has been gone since Mountain Lion and believe it also dates back to Lion.
I will wait with the update until Apples fixes the issues, mainly the user folders hiding. I see no benefit over 10.9.2 which is working just fine.
There's now a working fix for the hidden Users issue, but if something so immediately evident to (at a guess) a double-digit percentage of users has slipped through then who knows what other more subtle nasties may have been introduced?
I tend to avoid the first couple of releases of a new OS, but I think I'm going to have to review my policy of assuming that 10.x.2 and upwards are always going to be benign.
Some people won't be satisfied until they can get 24 bits/196 kHz refresh...wait, I digress...
I installed Mavericks (version 10.9.3) on my late 2013 iMac last night. I've resisted installing Mavericks because I was waiting for the return of iTunes to iOS device USB syncing of Contacts & Calendar.
Overall, my iMac is performing similarly to how it performed with Mountain Lion. The one exception being MAIL.
Mail under Mavericks is LETHARGIC compared to the performance I'm used to under Mountain Lion. Even the simple act of checking mail (how quickly the new emails appear within the inbox window) is slow on Mavericks. Then, when I use the delete key to delete emails, it can take a second or three before the email actually, you know, deletes.
I have three different gmail accounts and seven additional ISP email accounts. So, ten total email accounts that get managed with Mail. I have thousands of saved emails. Every email I've sent since 2006 is saved in Mail. That may be part of the problem (thousands of saved emails). But it was NOT this lethargic under Mountain Lion.
Other than that, I don't have anything else to complain about. I did a full backup (SuperDuper clone) before installing Mavericks. I'll decide within the next 24 hours whether I restore from backup and go back to Mountain Lion.

As of now, I don't aware of ANY computer video card or graphic chipset that's officially support HDMI 2.0. The problem isn't apple. I assume the video chip provider like nVidia, AMD and Intel need to do something or else we can't hook up our computer to the 4K TV.
Mavs completely changed the way Mail handles Gmail and it takes hours for the reindex that change caused to complete. Just launch Mail and leave it on and you should see speeds Mail responsiveness improve after a few hours.
Aslo make sure you have "All Mail" enabled for IMAP in the settings at gmail.com. Previously is was recommended turning this off, but now with Mavs you want it on.
installed 10.9.3 on a 2010 mac pro with sapphire 7950 mac edition and a sharp pn k321. previously with 10.9.2 and activated hidpi modes through quartz debug 1920x1080 hidpi worked good. now after the update i didn't get the five retina modes in display preferences. instead i have a big list of useless resolutions and every other than the native 3840x2160 crashes the system instantly and forces a reboot. now i need switchresx to reselect the hidpi mode. previously i also could run a second display from the dvi port, now only crashes.
it ****ed up big time. well it's unsupported so i don't have a valid reason to complain. stay on 10.9.2 for now if you have a similar setup.

In OS X Mail Preferences just set Mail to check for new mail every minute. You don't necessarily need Push mail on the Mac. It will update deleted or read messages from other Apple devices. Pretty simple.

Not happy
Since the upgrade, my 2011 MBP "13 tends to run hot (more than 100% cpu + fan noise) on certain webpages.

I ask the same question and get two different answers! What the heck is wrong with the the world??
Edit: second one was 2011 MBA. I reacted too soon.
Edit 2: BUT WHAT ABOUT THE 2010 MBA?!?!?
It's big, just download it and find out.
