Jon T Posted November 7, 2008 Share Posted November 7, 2008 Enter the following to darwin boot-prompt: "Graphics Mode"="1280x1024x32" . You can also add it to com.apple.boot.plist to use it automatically on boot. Too bad that there is no drivers support for 48xx yet. Perhaps I should get a used 8600GT or 2600Pro for hackintosh use I've read that specifying 32bpp can cause problems in some situations, so I exclude it, I've also been loading xwindows with the above as a switch. I use: -x "Graphics Mode"="1280x1024" Someone mentioned using a widescreen resolution above, you can't unfortunately as all VESA resolutions are 4:3. Cheers, Jon.

drumthrasher109 Posted November 8, 2008 Share Posted November 8, 2008 I just bought me a HIS 4850, it works great...except for the extreme CPU bottleneck on newer games. According to lastexile, the only hope we have is if 10.5.6 has any support for the 4xxx series. Link to comment Share on other sites More sharing options...
TurdFergasun Posted November 8, 2008 Share Posted November 8, 2008 well hopefully ati decides to release mac versions of the 48xx series separately from apple. would be nice. Link to comment Share on other sites More sharing options...
palbence Posted November 9, 2008 Share Posted November 9, 2008 now what shell i do? buy a 9800gtx+ or a hd4850 and wait? difficult decision as the hd4850 performs better, but i think i'll go for the 9800gtx+, as it already has leopard support.

nfinity_ Posted November 9, 2008 Share Posted November 9, 2008 i was in the same situation (of course i was)... i bought a 9800GT wich is cheaper but less powerfull. thinking abou 9800GX2 greets (though 2x 4850 would be awesome.. crossfire enabled board) Link to comment Share on other sites More sharing options...
fighterhawk Posted November 12, 2008 Share Posted November 12, 2008 Since the 4850 drivers aren't out yet i'm wondering does this mean I can install the kalyway disc and update it to 10.5.5 and keep. Will the card by default be running 1024x768 with everything disabled? or will it just not work and leave me with a black screen? Link to comment Share on other sites More sharing options...
fatherswatch Posted November 12, 2008 Share Posted November 12, 2008 It will just running in 1024*768 or any other 4:3 resolution Link to comment Share on other sites More sharing options...

nfinity_ Posted November 13, 2008 Share Posted November 13, 2008 tbh i think the best for now is either to stick with a cheap 9800GT if you are just running OSX. If you got windows on there too and can effort it... go for 9800GX2 (X2) it is nothing compared to 2x 4850 crossfire... but well, do we have a chance?

fighterhawk Posted November 13, 2008 Share Posted November 13, 2008 it works im running 1600x1200 but alot of stuff deosnt work like sleep... its pretty worthless really lol haha maybe so but my logic was i'l have a install all updated and with my various softwares installed and then all i'l need to do is pop in the drivers for the card when it comes out.

fighterhawk Posted November 14, 2008 Share Posted November 14, 2008 oh yeah one more thing i forgot to ask..now the 4850 has only 2xdvi ports and my lcd also has only 2 dvi ports...i read random stuff here and there about dvi not working and needing a dvi-vga adaptor in most cards etc....so whats the deal on that?

I don't get it, why does your LCD have 2 dvi ports?? For the rest of the question though, I use 2 HD LCDs with 4870x2 with no problem, both connected via HDCP DVI. And have never no trouble using 2 DVI with all cards I've had since I have 2 LCDs. Link to comment Share on other sites More sharing options...
kodek Posted November 14, 2008 Share Posted November 14, 2008 Maybe his monitor has two digital inputs. It's rare, but it doesn't sound bad. I also don't think that card will give you problems with the DVI ports (but I'm just speaking from experience). Link to comment Share on other sites More sharing options...
ago Posted November 15, 2008 Share Posted November 15, 2008 no problem with dvi, I use mine on both sides and they work. Link to comment Share on other sites More sharing options...
fighterhawk Posted November 16, 2008 Share Posted November 16, 2008 yup it does have 2 digital inputs so you can hookup 2 things (like a xbox / ps3 along with the pc) and switch...thanks for the replies cleared all my doubts. Link to comment Share on other sites More sharing options...
meroupow Posted November 17, 2008 Share Posted November 17, 2008 Hello, I also managed to get to the point where everything is working except I run under VESA driver (EP45-DS3R + Q6600 + ATI HD4850). I am using iDeneb 10.5.5 with option "Graphics Mode"="1600x1200x24". I would say OSX is more than usable like this but one the main reasons for me to use OSX is iMovie and I am looking for a workaround like everybody here in order to activate QE. My motherboard has got 2 PCI-E x16, do you think it would be possible to install a second very small graphic card well supported by OSX (like ATI HD2400 Pro for exemple which is less than 30€) just to enable iMovie. I have 3 OS on my computer: - Windows for games - Ubuntu for tweaking and experimentations - OSX for Video editing, and Music & Pictures database Basically the idea would be to use the HD4850 under Windows and Ubuntu and HD2400 under OSX. Do you think it is feasible? Link to comment Share on other sites More sharing options...
hindug Posted November 17, 2008 Share Posted November 17, 2008 I don't get it, why does your LCD have 2 dvi ports?? So it can be used with multiple sources. My 30" HP has 3 DVI inputs. Link to comment Share on other sites More sharing options...

drbadass Posted November 18, 2008 Share Posted November 18, 2008 subscribed =) A little off topic, but i saw an faq saying our hackintoshes wouldn't work as well as a normal mac... i wonder why that is when the hardware is often equivalent-to-superior? (as the HD 48xx series seems to be at the moment..) in that vein, assuming we do eventually get these cards working, is final cut a viable app on these computers? or a waste of time?

It's unfortunate you have two demanding cards, but HD 2400 and GF 8400's are around £15/20 at the moment, if you need to in the future it shouldn't be too much money to give it a shot. Maybe you could sell the 1900 to a friend? subscribed =) A little off topic, but i saw an faq saying our hackintoshes wouldn't work as well as a normal mac... i wonder why that is when the hardware is often equivalent-to-superior?

I run BOINC on 10.5.5 and I get a higher CPU score than in Windows (Both 64 bit). Hackintosh has run even the most copy protected (by dongle or other hardware device) applications for me and a friend so far so I think the operating system is not as limited as people might want you to believe. Maybe drivers for other hardware isn't quite up to full optimisation but that's nothing really to do with OSX itself, there's no reason it should be slower if all hardware is properly supported. I just look forward to the 48x0 support so I can run some complete benchmarks, and TF2 Link to comment Share on other sites More sharing options...

Do you think it is feasible? yes this is what i plan on doing also from what i have read, you put the osx gpu in the primary slot, and the windows one in the secondary slot. install the drivers in osx for that card, then in windows disable the card from device manager please let me know how you go on.

drumthrasher109 Posted November 18, 2008 Share Posted November 18, 2008 9800GTX vs 4850: 4850 is WAY better. Link to comment Share on other sites More sharing options...
abhi262 Posted November 19, 2008 Share Posted November 19, 2008 9800GTX vs 4850: 4850 is WAY better. I wouldnt say WAY better, but it is a bit better. Personally, i wouldnt mind owning either, with the 9800GTX running a bit cooler and the 4850 running a bit faster. The difference is not so great that you would ever encounter a situation where you could not run something with the 9800GTX but you could with the 4850. For a start the 9800gtx works in leopard but the 4850 doesnt... Anyway, back on topic so should the card be compatibile with the 10.5.6 update? Roughly how long would it take for this to be released? 1 week? 1 month? 4 months? Thanks, i cant wait to use my 4850. Link to comment Share on other sites More sharing options...
maukku Posted November 20, 2008 Share Posted November 20, 2008 http://news.softpedia.com/news/Mac-OS-X-10...day-98107.shtml . Looks promising. Let's just cross our fingers and hope that it contains support for these cards Link to comment Share on other sites More sharing options...
