    If this were an EFI issue would it not effect Windows as well? Think about it, Apple is delibertly making this card not work on older Mac Pro models because they do not want to support it. I bet if someone was to edit the binary for the HDMI Audio kext they could probably disable the system model checker so that the driver would load. All we need is someone who is good at editing kext files.

    I am not an expert on these matters, but my impression was a non-Apple card under Windows used BIOS, and that the Apple card under Windows used the BIOS subset of the Apple Card's capabilities.

    Apple could fix this if they wanted too.


    They could also issue a firmware update for 1,1 and 2,1 Mac Pros to allow them to use newer, faster Nvidia cards.


    Don't hold your breath for either thing.

    DPArt,hello,i´m usin a Mac Pro just to stay on line and maybe,if i could,for to play games,even windows games....Mac Pro 1,1  don´t use the audio of 5770,at least,the back a videocard from aple not a major problem...but...and belive me,sometimes it happens,maybe you have answer some people and don´t know if they have bought their machines out of the States or other countries,you know how capitalism leave besides some aspects clients are all the same,i don´t sell in "x" country what i don´t sell in "Y" country...maybe you understand me...i can´t play some games because the video card is not recognized by the sistem as others video cards.....(even RAGE and Borderlands origanalls from apple don´t use my 1 GB...)your video card don´t support now,just happens with portables,X-cyder,wine,Crossover...but...and belive me,i really appreciate the effort doing this video card to be used with my old 1,1...can you belive me when i say that untill i´ve tried to play i even didn´t use the audio form Mac pro...yes...very good audio card....i´m usin my very expensive Mac just for to i deserve no support because is 5 years old???...don´t talk about price

    What you can not denie:Mac is more stable,easy and they serve,when you know what expecific thing to do,for what they use them....

    They should have thought many years ago in some other aspects,like better video cards for to play,a normal support when you don´t have internet,conectivity as others computers,and,keep high prices giving high solutions....yes,many people will don´t pay,but Mac are supposed to be the ones that buy people who pay after for support,software...Mac,please,por favor,make them for more people,change your company attack...not just for rich people.....just give other people a chance!!!

    Beware of ATI Radeon HD 5770: It works only up to Mac OS 10.6 (Snow Leopard). It does not work properly on Mac OS 10.7 (Lion) on my Mac Pro 2,1.


    Bad symptoms shown on Lion are: jumpy mouse and flickering on second monitor.


    Solution: install original OEM video card back to the MacPro and ditch the ATI Radeon HD 5770 video card (very unfortunely). Or downgrade back to Snow Leopard if you want to keep the ATI Radeon HD 5770 video card.

    Chiravouth Noradom-


    Could you please share with Readers the basis for your dire pronouncement?


    If you are basing this on published articles, could you please provide a link to some of those articles?


    If you are basing this only on your own experience, I suggest you may have a card with a sample defect that is keeping your card from performing properly on your Mac.

  • Chiravouth Norodom Level 1 (25 points)

    I bought my ATI Radeon HD 5770 brand new from Apple Online Store a year ago when my Mac Pro was still in Snow Leopard. It was working perfectly with my Maxon Cinema 4D (which is the main reason I bought this card). Rotating 3D models was very smooth. And there was no glitches with any other software or with any internal or external hardware such as monitors (Acer and Dell). Recently a new project came up that requires me to upgrade to Lion (the last supported OS for Mac Pro 2,1). My new project requires using iBook Author which supports only OS 10.7 and up. iBook Author does not work with Snow Leopard.


    After successfully installed Lion on my Mac Pro 2,1 with ATI Radeon HD 5770 still intacted, unusual things began to happen like jerky wired Apple mighty mouse movement and the second monitor flickers every few minutes. My Mac was not usable until I put back my original card that came with the Mac Pro and then my Mac behaves normally again.


    ATI Radeon HD 5770 is a powerful card and it's still used on current MacPro models (5,1) in the Apple Store. Unfortunately it's a no go on MacPro 2,1 with Lion. Perhaps on the current model Apple/ATI may had updated the video firmware (video BIOS) for the latest Mac Pro.

  • DPArt Level 3 (555 points)

    I believe that you are incorrect in your observations or your card has issues.


    People all over the globe are using 5770s in 1,1 and 2,1 machines in Lion and you are the only one of them with these complaints.

  • Peter Jason Level 1 (15 points)

    I have the Mac Pro 1,1 2006 and also have the Apple HD5770 and works perfect in 10.7.5 for me. Not sure why you have issues but maybe you need a fresh install not an upgrade to Lion.

  • Chiravouth Norodom Level 1 (25 points)

    Wow. How do you know? 1,1 and 2,1 don't come with 5770s. Their stock video cards are NVIDIA series and ATI X1900 only. So the whole world were all upgraded to 5770 and working fine? You are not much of a help here.

  • Chiravouth Norodom Level 1 (25 points)

    I was thinking about fresh installing but maybe not. I have too many software in my system that needed to be de-activated and re-installed also. I work for a design adgency and it's a nightmare to reinstall everything from scratch while we constantly having deadlines. The best route is to install on a newer system and take it from there.


    If it's my home computer, I would definitely invest the time to sort this problem out. I bet the culprit is in the "too many software" somewhere.

    Chiravouth Noradom-


    You have made two changes upgrade to 10.7, and using a new Application), each of which require quite a bit more memory. Mac OSA X is a highly Virtual Memory based system, and crossing from occasional Virtual Memory use to substantial Virtual Mmeory use will cause hesitation in model display like what you describe.


    This article will allow you to examine your memory use while the model is displaying. Susbstantial use of PageOuts or Swap Used are an indication you may have too little real RAM installed for the work you are doing.

    I "had" a MacPro 2006 (1,1) and used the 5770 in it.  You don't get the full potential of the 5770 as it was designed for PCI 2.0 spec (we're now on PCI 3.0 spec) ... but specific to your issue.  I'm also a Cinema 4D user (R14 Studio) and when I upgraded from SL to Lion had the same problem.  It's a known problem with going the upgrade (rather than fresh install) route ... I made Apple aware but they showed no interest given I had a 1,1 MacPro.


    First execute this from Terminal:


    ioreg -l -p IODeviceTree | grep firmware-abi


    If it says "EFI32" (which is should for a 1,1 or 2,1 MacPro)


    Now you need to get ML on a USB stick see here: on-drive/


    I'm trying to recall all the details so bare with me, I was able to avoid a complete wipe and re-install by finding the ML drivers on the USB stick.  Then locate the ATI drivers in "Mac OS X Base System"/System/Library/Extensions -- copy them elsewhere and delete something like ATIxxxxcontroller.kext (I think ATI5000controller.kext).  Then you'll need to re-install the atixxxxcontroller.kext (from USB stick) and then rebuild the kext cache.  Be warned, do this at your OWN RISK and be prepared to do a complete wipe re-install if it doesn't work for you.


    Also, you need to be aware that Apple are 1 full generation behind in OpenGL - Mountain Lion support version 3.1 (OpenGL is currently at 4.3).  I migrated all my OSX software (Adobe, Cinema 4D, everything I could) over to Windows 7 based PC's because of the lack of updates to the MacPro line and ATI/nVidia support OpenGL 4.x on Windows 7.  If you are doing professional video/animation work, you really are better off on a Windows 7 platform.  I was able to build an AMD based 64 cpu (4 x 16 CPUs, real CPUs not hyperthreaded) 256GB RAM and 750 GB SSD RAID setup for $6500 ... for rendering Cinema 4D work it's approximately 300% faster than the best MacPro you can build for 1/3 the cost.


    But good luck, Apple are very uninsterested in their desktop platforms.  You will also get better support from other places like MacRumors in terms of problem recognition and solutions.  This place is blinded by "Apple has no issues".


    Hope this helps.

    Thanks for the detail tips. The Windows machine sounds really good. 100% agree on MacPro is overprice. However we don't just do 3D/animation/video. We are also web/print powerhouse. MacPro just fits the jobs plus our staffs are all on Mac. I am not going to bother messing around with this old MacPro (2,1). I am going to migrate everything to a newer Mac (4,1) from an ex-co-worker and it has a better stock video card and CPU. I have to proceed this way so I can continue to work while in the process of migrating and upgrading. My company didn't approve me for getting the new MacPro (5,1). Go figure.

  • Rob A. Level 1 (40 points)

    What I've learned from the "Apple way" is that you pretty much need to stay no more than 2 hardware generations away from their most recent OS (be it OSX or iOS based computers).  I can understand you not wanting to mess with the 2,1 MacPro ... most folks buy Apple hardware because they don't wanna mess with them ... the $$$ shock comes when they realize if they want lastest OS they better be within 2 generations.


    It has it's pluses and minuses ... on the plus side less work for Apple and less "compatibility" layers which will keep the OS footprint and memory usage smaller.  The minuses is obviously having to retire hardware that is perfectly good for the task at hand.


    It's a shame you had to install ML, I still prefer SL as ML didn't really bring anything to the table for me ... who knows, maybe if Apple ever move to OpenGL 4.x, I'll take another look at iMac's.
