I had the same problem. This is a dsdt with HD5770 patch. Try it out.

(have non apple flashed HD5770)
Firstly thanks for making that available. Unfortunately, when booting up with your supplied dsdt, Chameleon gets as far as the very "apple like" boot theme and as the bar line gets to about the half way mark, all graphics abruptly shut down and the little white light on the bottom right hand corner of my 20" Apple Cinema Display begins blinking. I even attempted the boot with a variety of different key entries graphics wise in my org.chameleon.Boot.plist. In the final try, I stripped the org.chameleon.Boot.plist entirely of all graphic references and yet still no luck
Since any fix besides setting GraphicsEnabler = No involved patching the dsdt just as you have done, I am wondering if the genuine Apple ATI HD 5770 might have a different ID then the flashed version. Did you make the edit to your dsdt yourself and is there a resource that might explain where I can locate my cards specific ID information and how to make the dsdt edit?
gpatpandp any idea how your iMessage is working?
Yes it actually was a fairly common fix back before the NVRAM module was invented. I know it sounds a tad laborious but it indeed works. Basically you need to set-up an alternate "BOOT" partition utilizing Clover. If you scroll back to like the midway point of either page 4 or 5 of this very same forum discussion, all the instructions/pictures/files are there. You will need to format a Hard Drive to "MBR/HFS +" and create a BOOT partition the same as you did with Chameleon. Then boot your OS X 10.10 Yosemite system just one time in Clover, log into both iMessage/FaceTime and all will be well when booting into Chameleon thereafter.
Works absolutely perfectly !!! Brilliant...please do not hesitate to call upon my assistance should you ever find yourself in need. Thanks again !

I am going to finally do this tonight but I wonder why this works...
Update:
This did work and I now have iMessage when using Chameleon. I had to do it quick because after the login screen appeared I was getting a kernel panic after about 45 seconds. It was long enough for me to login and sign in to iMessage and set the initial options. Thanks

I updated from 10.9 to 10.10 in a supported Mac and it had imessage logged in but it never stayed logged in when I put the drive back in my Mac Pro
Also noticed everyone's Mac says 0mhz ram in about this mac

MacPwn for Yosemite - does it work with unsupported Mac?
Hi guys... I'm still trying to find a way for install Yosemite on my unsupported Mac mini...
I find this guide for creating a USB installer using MacPwn...
http://www.niresh.co/apple/macpwn/install-os-x-yosemite-on-pc/
I don't know if I understood, but I think that this app (MacPwn) can help user creating the USB installer with a boot loader (clover or chameleon).
Anyway I did'n understand if it works only for hacking lash or even for real UNSUPPORTED Mac ... And in this case I CAN'T UNDERSTAND HOW TO SET IT TO WORK....
Does anybody used it? Can someone tell me how to set it for working with my unsupported Mac mini?
Last question: once I create the USB installer is it possible to use it for install Yosemite on the main hard disk where I made 3 partition (one of which with Mavericks installed thanks to Tiamo boot) ?
Thanks...

Hallo gpatpandp.
I am glad it works.
Can you briefly describe how you have Clover installed. For me, Clover does not boot.
My mac pro starts in legacy mode, it remains just a black screen with a blinking line at the top left.

I don't think you can boot unsupported Mac OS's off USB due to legacy mode
OK Let's see...
1.) The "BOOT" partition that your installing Clover to needs to be formatted in MBR and Mac Extended Journaled
2.) Once you have formatted appropriately, open Clover, select "BOOT" as the destination and select/check only the boxes as shown in the *picture* and install
3.) Once installed, grab this Clover config.plist here: https://dl.dropboxusercontent.com/u/12608634/config.plist
...and replace the default with the one you downloaded
4.) It also helps to install your dsdt.aml in Clover as well...here is the path: /EFI/ CLOVER/ACPI/patched
5.) Last step is to bless your BOOT partition just as you did with Chameleon:
sudo bless --folder=/Volumes/BOOT --file=/Volumes/BOOT/EFI/BOOT/BOOTX64.efi --setBoot --legacy
You will know if you have done it correctly when once everything is completed and you restart and press the "Alt" key (as soon as you hear the Apple chime) and in the menu of bootable partitions, you see one entitled "Windows".
Once you click on that, the next sign that your in good shape is for a brief moment in DOS/Darwin lettering you will briefly see the following "bif : init:6"
...once that flashes, it will take you to the Clover boot menu and there you simply use your arrow keys to scroll through until you find whatever you named your Yosemite install. Click on that and bingo...your done.
PS. This might be stating the obvious but this process absolutely needs to be done entirely on two different/separate hard drives. One containing your OS X 10.10 Install and the other your Clover BOOT partition

This is just cosmetic and can be fixed by adding this to your smbios.plist
Code:
<key>SMmemspeed</key>
<string>667</string>
<key>SMmemtype</key>
<string>20</string>I mean "officially unsupported" but the hardware should support it ad it support mavericks...
It's an Intel core 2 duo with 3Gb RAM..
Mavericks works well...
Our Mac Pros cannot boot 10.8, 10.9 or 10.10 VIA USB. [Via legacy boot]
May apply to yours too
Cheers budski
Man the green button making everything full screen is driving me crazy! I use dual 1080p screens and its flaming annoying! I don't use full screen mode before, not want to use it now
I have an app called Tuba... used for watching youtube on Macs. Does not run in 10.10.
I have parallels desktop too. Doesn't like to boot Mac OS X (error about saying requires 10.5.1 or higher or something like that) under it unless it has this command
sudo nvram 8BE4DF61-93CA-11d2-AA0D-00E098032B8C:BootCurrent=1
This will let people use parallels to run 10.9 and keep their apps working

No offense or disrespect intended however it is rather useless/pointless to install Mavericks/Yosemite on any Mac that possesses unsupported permanent inboard graphics. In fact just the other day, (and this is despite being a major contributor in developing the "gpatpandp" method for installing OS X Mountain Lion in 64 bit mode (100% functional without utilizing MLPF) on Macs with ATI X1600 inboard graphics) we finally bid a "fond farewell" to our 2006 iMac due to the fact that neither Mavericks and now certainly Yosemite are even a remote possibility for our otherwise competent/trustworthy old friend.
It's been getting on my nerves to. I've been double clicking the window instead. That effectively does what the maximise button did in MV.
It looks like a UUID from something. Back when I was running Mavericks using Chameleon I was having troubles creating a VM using Parallels 9 and their support had me enter a bunch of commands similar to that one. They never ended up working but I think that was because of the FileNVRAM.dylib used to fix iMessage. When I started using Tiamo's boot.efi, Parallels worked fine.
I'm not sure right now, and I don't think I can verify it immediately, but I strongly suspect that is a PERSONAL string that identifies your computer or Messages/FaceTime user. It is derived from a non-Chameleon boot; for instance, from Snow Leopard on the same computer. My hunch is that if you copy that particular string from someone else, you'll probably botch your installation. I suggest that you try to verify my hunch and, in case I'm right, act accordingly.
Nope, it's a SimpleBootFlag Variable (see attachment).

Sorry but i don't agree with you... I use my maximin just for email, Word and browsing...
And for me it's enough
I'm using Mavericks since months now and for me it's great...
I really like new Yosemite's graphic and I really enjoy using it

While I completely and utterly fail to comprehend even the most minuscule thread of your logic (in the same manner that I have never understood those that opt to use a MLPF 10.8 system over a OS X 10.7 Lion system...a 32 bit system is a 32 bit system no matter how you slice it....no one will ever convince me of the alleged speed boost achieved in a MLPF system and in Lion your fully functional versus a MLPF system that is significantly hindered functionally) you know what...my opinion does not matter in the least. Your happy with it and it works for what you need it for and that is ALL that matters.
