Any idea how new of a macbook you would need to power this? I'm guessing my 2012 13" air can't run it right?

Looking at another 4K monitor in the Apple Store (http://store.apple.com/us/product/HD971LL/A/sharp-32-pn-k321-4k-ultra-hd-led-monitor http://store.apple.com/us/product/HD971LL/A/sharp-32-pn-k321...), doesn't look like it: "Note that 4K DisplayPort operation is only compatible with the new Mac Pro (Late 2013). 4K HDMI operation is compatible with MacBook Pro (Late 2013) and the new Mac Pro (Late 2013). HDMI input is not available in the European-market Sharp PN-K321."

Even a brand-new Macbook would be unable to power this display. All currently sold Macbooks can only power displays up to 2560 by 1600; the Macbook Air can power one external display at this resolution, and the Macbook Pro can power two. (Edit: The iMac can also only power one additional display at the same resolution.) If you want to use a Mac with a 4K display, consider getting a Mac Pro, which can power up to three of them.

  This article claims the hardware in the latest macbooks can support it, but the current osx drivers max out at 30hz: http://9to5mac.com/2013/12/23/new-retina-macbook-pros-can-drive-4k-displays-at-60hz-when-running-windows-mac-os-needs-new-drivers/ http://9to5mac.com/2013/12/23/new-retina-macbook-pros-can-dr...

  The MacBook Air from 2012 or later can drive two 2560x1600 displays at 60fps: https://twitter.com/Antagonist/status/252936243606859777/photo/1 https://twitter.com/Antagonist/status/252936243606859777/pho... (It only has one Thunderbolt port, but Thunderbolt displays can be chained.) While the integrated graphics on the 2013 models can drive 4k displays at 60fps, only Thunderbolt 2 has the necessary bandwidth. The latest rMBPs have Thunderbolt 2, so they should be fine once OS X's drivers are updated. Everything else is stuck at 30fps.

  I think you are wrong here. I've used a late-2013 rMBP with a 4K monitor (OS 10.9.1) at 30Hz. It's a supported configuration (http://support.apple.com/kb/HT6008?viewlocale=en_US&locale=en_US http://support.apple.com/kb/HT6008?viewlocale=en_US&locale=e...).

  (Note that according to that page, the MacBook will only do 30 Hz.)

    60 if display port is available (which it is on this Dell).

Looks like I'll be finally buying dedicated graphics card for my Hackintosh.

You can drive 4k with a recent macbook, but it's laggy as sin. My Amazon review: http://www.amazon.com/review/R4OJ5D5RPILCH/ http://www.amazon.com/review/R4OJ5D5RPILCH/

  Thanks for that note. I was at the Apple store in Pasadena this week checking out a new rMPB (OS 10.9.1) and the Sharp 4K monitor. They connect by HDMI, not DP, at the moment. This limits refresh to 30Hz. I did not notice the lag on text input that you did (but, I did not enter much text; I didn't think of this as a possible issue). I also did not notice any significant lag with the mouse. This may be user-dependent. The thing I did notice is poor rendering of some fonts. There were colored fringes around the system font that both the Apple rep and I noticed. Other common fonts were affected as well, but not all of them. It seemed like a problem with subpixel rendering to me. Changing the display mode to mirroring did not help. The Mac Pro did not have these problems. It's quite smooth (60Hz) from the Mac Pro. It was bad enough that it disqualified the monitor for me. I assume it's an artifact of the HDMI driver they're using, and "probably" fixable with a better driver. But you never know.

    Interesting. FWIW, this isn't 30 hz vs 60 hz. My windows box is limited to the same 30 hz and has no issues.
