Now that Maverick has been out for a while I am wondering if all (most of) the bugs have been worked out? Specifically is anyone having trouble running the EOS capture software/DPP/ or CS6 Photoshop/Premier?
Thanks for any insights,
Don't do it if you have a non-retina MAC or anything but the latest MAC Pro otherwise you won't be able to use the hacks to drive UHD monitors! I actually got a MAC MINI to drive 3840x2160 perfectly! But it only works pre-Mavericks!
What hacks did you have to do?
I have a macbook pro, late 2011 model, non-retina. I was able to drive a Dell U2711 at 2550x1440 merely by getting a thunderbolt to display port adapter to connect them. Seems to work just fine with no "hacks" of any type.
Can you explain what you had to do to get yours to work?
I'm talking UHD (3840x2160 not 2560x1440).
My Mac mini has Intel 4000 graphics (and the hack should work for the slightly older machines with Intel 3000 graphics and perhaps in a few other cases as well). Intel put out UHD drivers for the chipset last year, but Apple kept their hardware locked down. And you also need to do some extra steps to enable scaling since there is no way direct way to make Mac OS scale nicely from the OS control panel itself (icons and text become crazy small without the scale factor stuff).
OK, wow, actually got my MAC Mini to be able to support 3840x2160 or 1920x1080p HiDPI modes. It took a lot of searching and some hacking and some serious scares along the way though! And most google searches only lead you to partial solutions or talk that it's impossible. But 2 hours later it works.
I have no clue what Apple fans go on about how MS has no clue compared to Apple when getting UHD running on a regular MAC is so tricky and not directly supported in the OS. Direct support was only for 1920x1080p (which interestingly enough the Dell UP2414Q actually WAS able to scale to fit the screen and run at 60Hz, although it doesn't do simple scaling but interpolation so it's a bit blurry looking from the interpolation). And supposedly there is no way to make it work, even with hacks, if you have already upgraded to Mavericks, which thankfully I had not.
Once you do all the hacking though it appears, at first glance, to work quite well though and perhaps better than Windows although I can't yet say. I don't have much software for the Mac since I basically only use it for tablet development. Although Apple still has 60Hz support locked out for some reason running at UHD so you have to live with either 30Hz and UHD or 60Hz but interpolated by the monitor 1920x1080.
Anyway when I did these steps and used HDMI I got locked into a no signal mode and my HDMI port now seems to be locked out of working with this UHD Dell monitor, although the port still works if I use with other monitors that it recognizes as being different brand. And then I found that using DisplayPort it still works with the Dell even at UHD and I can get in and reset things for this monitor.
Anyway here are the steps:
0. Make sure you have NOT installed Mavericks! AFAIK it only works with OS SUB 10.9, at least so far. And maybe for extra safeties sake check to see what chipset your Mac has and whether you find out if anyone has had it working at UHD before or if you can find UHD support for that chipset on other OS, then it should be safe for sure I'd think.
1. use the DisplayPort and not HDMI connector.
2. Go here and follow the http://code.google.com/p/mac-pixel-clock-patch/wiki/Documentation to install the mac-pixel-clock patch to unlock higher pixel clocks.
3. Go here http://www.madrau.com/srx_download/download.html and download and install SwitchResX and select UHD mode for DisplayPort.
4. Go to create custom resolutions in SwitchResX and simple make a new 3840x2160 mode. Exit out of SwitchResX and agree to save changes.
5. Go here http://cocoamanifest.net/articles/2013/01/turn-on-hidpi-retina-mode-on-an-ordinary-mac.html and follow the instructions to turn on HiDPI mode options.
6. Re-boot. You will notice that the HiDPI modes offered by the OS Display preferences are stinking options, there is no 1080P natural scale factor option and the ones they offer make the screen shake and are too lo-res.
7. So go back into SwitchResX and you will now find a 1080P HiDPI option. Select that and then finally you have both UHD AND all the text and icons not being hideously small running even on a MAC Mini or other non-retina MAC (maybe much older models this won't work for, my MAC Mini is only a bit over a year old)
So wow even a non-retina, little old Mac Mini can drive it just fine! At least if it is fairly recent. In this case it was a 2012 model with Intel 4000 graphics. It should work at least as far back as the Intel 3000 chipped ones though.
Well, so long as you didn't go to Mavericks! Hopefully they will hack Mavericks too (although apparently Apple now signs the code block so I don't know, hopefully Apple will unlock UHD support themselves, feels like they just want people to buy new machines though hmmmm). You can only do it at 30Hz though as for some reason Apple doesn't seem to have 60Hz working when paired with quite a few of the UHD monitors. Mosts current monitors need a special dual displays as one driving hack and with some screens it doesn't seem to work with Apple for some reason so you need to drop down to 30Hz.
