It seems to work fine. I installed it onto a Dell Latitude E6420 that has HD3000 and am using an older version of AppleIntelSNBGraphicsFB.kext from Yosemite. I have yet to poke around with the updated kext but I had to use the older one in order to boot the install media.

On my E6420 (NVS4200 disabled) with HD3000 no issues, no kext replaced.

But no metal

On my E6420 (NVS4200 disabled) with HD3000 no issues, no kext replaced.

But no metal

According to http://netkas.org/?p=1405:

 

Metal supported card families:

Nvidia – GeForce gtx 4xx and newer

Intel – HD4000 and newer (ivy bridge and newer)

AMD – HD7000 and newer

Ok guys fixed it, lurked some russian forums and found out that even 10.10.3 has issues with hd 7770 and some other graphic cards.

Fixed with this kext https://www.dropbox.com/s/2gdj3zm6safrzou/Verde.kext.zip?dl=0 and its working now.

It feels a lot faster than yosemite on this machine.

Link to said forum post, plz?  Do you know what, exactly, was patched in the kext you posted?

Okay, according to this post, the "CAIL" values of AMDVerdeGraphicsAccelerator in AMDRadeonX4000's Info.plist have to be reverted to 10.10.2's values.  So this (from 10.11 DP1 kext): 

<key>AMDVerdeGraphicsAccelerator</key>
		<dict>
			[...]
			<key>cail_properties</key>
			<dict>
				<key>CAIL_DisableDrmdmaPowerGating</key>
				<integer>0</integer>
				<key>CAIL_DisableDynamicGfxMGPowerGating</key>
				<integer>1</integer>
				<key>CAIL_DisableGfxCGPowerGating</key>
				<integer>0</integer>
				<key>CAIL_DisableGmcPowerGating</key>
				<integer>1</integer>
				<key>CAIL_DisableStaticGfxMGPowerGating</key>
				<integer>1</integer>
				<key>CAIL_DisableUVDPowerGating</key>
				<integer>0</integer>
				<key>CAIL_DisableVCEPowerGating</key>
				<integer>0</integer>
			</dict>
		</dict>
Would become this:

<key>AMDVerdeGraphicsAccelerator</key>
		<dict>
			[...]
			<key>cail_properties</key>
			<dict>
				<key>CAIL_DisableDrmdmaPowerGating</key>
				<integer>1</integer>
				<key>CAIL_DisableDynamicGfxMGPowerGating</key>
				<integer>1</integer>
				<key>CAIL_DisableGfxCGPowerGating</key>
				<integer>1</integer>
				<key>CAIL_DisableGmcPowerGating</key>
				<integer>1</integer>
				<key>CAIL_DisableStaticGfxMGPowerGating</key>
				<integer>1</integer>
				<key>CAIL_DisableUVDPowerGating</key>
				<integer>0</integer>
				<key>CAIL_DisableVCEPowerGating</key>
				<integer>1</integer>
			</dict>
		</dict>

All you need is proper DSDT edit, no need for de-graded kexts, That really defeats the purpose of an upgrade/update.

Could we get a link to said DSDT patch, if you don't mind me asking?

 

Thanks! :)

@Diazz72 

please! no need to get angry  :P

 

Not angry...ANNOYED ;D

 

I mean i can understand question like that if this thread have 100 pages and you do not want to read every one...but two and a half pages whit answer om the middle for not even a day old OS and every 2 guy is asking the same question is really annoying...and even spamming.

 

And its seams to be effective...i do not see anyone anymore asking about it :).

Only issue I'm having so far guys is that every login I get stuck at a black screen with the spinning beachball for about 30 seconds to a minute before it continues to desktop.  The Finder also crashes when I go to restart or shutdown.  

 

Also having USB issues but I believe that's just related to it being a DP and needing to have the bugs worked out.  

 

Anyone else?

Hi, with some problems since I do not use Clover (I don't know much about it) but Chameleon and thanks to the suggests here, I was able to install everything. Now the problem is that I have a  "mixed" (Sandy Bridge Intel 2500k - Intel HD 3000) configuration and also with Yosemite I have to use modified kexts to make it work perfectly. El Capitan considers the card as a HD 2000 with 7 m of RAM. I do not know what to do to eliminate the problem. Any suggestion to a Clover neophyte would be really appreciated. Thank you.
