Hello guys. I own a V3-571G, not  a 771. Anyway, I read that BIOS (UEFI one, v. 2.x) is completely locked and cannot be modded. I can't get HW acc. on my HD4000 (which is the same for both 771g and 751g), because the kexts I loaded are incompatible with 128MB of VRAM. How can I solve the problem? I tried various methods but didn't find the correct one yet. Thanks to anyone will try to help me!

Did you try to inject HD4000 device-id in Chameleon bootloader? No need to install other kexts.You can use Chameleon Wizard to set the device properties.Also make sure you delete NVidia kexts from /Extensions in case you have another video card like  NVidia Optimus Technology which switches graphic cards.I can not get into  OS X if I have nvidia kexts in extensions.Any software update is likely to reinstall Nvidia kexts you deleted,so you should delete them after software updates.Hope this helps.

Yes I already deleted all nVidia kexts. The problem is: how can I get the string to inject it in the bootloader? I already have a string, but I never injected it.

 

Here it is:

<key>HD4000PlatformId</key>
<string>9</string>

<key>device-properties</key> <string>5e0000000100000001000000520000000100000002010c00d041030a000000000101060000027fff04002c0000004100410050004c002c00690067002d0070006c006100740066006f0072006d002d006900640000000800000003006601</string>

 

Well, I must say that I installed some HD4000 kexts found on the internet, but they seems to not work. Maybe that kexts injected the string? Don't know...

Should I try with some other strings? (where to get them)

 

Thank you anyway

Try this,but adjust it, I mean the resolution in case case it does not correspond and also delete the DSDT entry if you don't have DSDT.aml file accustomed to your laptop.Copy and paste the code below in your Extra/org.chameleon.Boot.plist  or just use Chameleon Wizard which will be easier cause you'll have an interface from where you can choose all the options.

I didn`t copy in that size stuff to my OS X but I am using the OS for more than 5 months on V3-771g and have no problem and I have downloaded big torrents,I am using VMware Fusion on OS X which uses virtual machines which take more than 10 GB in size and I got no problem.Also,I have 2 HDDs and I keep one for Windows and OS X and the other one for Storage...no issue at all.How ever if you look back in my earlier posts I posted something about freezing "4/17/13 9:13:25.304 PM powerd[17]: FIXME: IOUnserialize has detected a string that is not valid UTF-8, "+Pb".This made my laptop freeze and it was coming from the kexts which I was installing just to test which work and which don`t.However I did reinstall OS X fresh! and it worked fine and of course I keep a System Image of it just so that I don`t have to get through all the steps all over again and to waste time again.

 

 

The only issues I have are:

1.the CPU which does not go up to max frequency 3.1ghz .Max Speed 3.1ghz represents actually the turbo boost technology and it seems it gets hotter by up to 2 -3 degrees  more than in Windows which has all the features.

2.the Screen backlid display which does not boot with the ability to reach full brightness.If I want full brightness I have to enter sleep mode and resume from it.

 

Check out the kexts from the earlier posts,use them on a fresh installation of OS X.

That is the exact issue I experienced and what I did was a fresh install of OS X with the kexts below:

 


 

In the link there are:

 

Applications for configuring OS X : Chameleon Wizard,DSDT editor and KextWizard

 

DSDT Patches for screen brightness configuration using the keys to increase and decrease and other patches in DSDTEditor.zip which you may try

 

Kexts for

 

-ALPS multitouch(enables 2 finger scrolling),

-AppleSmartBatteryManagement(to view battery),

-GenericUSBHCI(to make USB 3.0 work and fix freezing for couple of seconds issue when pluging in USB)

-SleepEnabler(to enable sleep and get full brightness of the display when wake up),

-VoodooHDA 2.8.0(Good audio quality)

-VoodooPS2Controller(other stuff)

Did anyone fix the brightness issue cause I have to always enter sleep mode to reach full brightness,how about the cpu i5-3210m can`t reach 3.1ghz stays at 2.5

 For the Brightness issue i don't really know how to fix it, i have the same problem.. For 3.1Ghz you must try different SMBios.plist from 8.1 to 10.1 one of the system might get you 3.1 Ghz. I have a different Cpu so mine SMBios was 10.1 i get  3.1 Ghz. I also have multi gestures trackpad working. I recommend looking on this site for multitouch, if someone is interested http://forum.osxlatitude.com/index.php?/topic/1948-elan-touchpad-driver-mac-os-x/

Hi,

 

so the same problems out there like a few weeks ago...

 

iClock, the ALPS kext I am using did not work for you? - well it is still working fine here. I think I should tkae a look for an update.

The Brightness on my machine is somekind of fixed. Using Brightness Programm and a DSDT patch and a patched Intel kernel extension... One thing of it fixed it.

And last but not least: Yep, the Turbo Boost is enabled by choosing the right SMBIOS type for Speedstepping. You really have to test it from 8,1 as a starting point to 10,1. Patching the Powermanagement will help as well...

Hi there,

 

well, strangest things are happening here...

I read on this forum (

 

Reading further more on different topics there, I found an article that mentioned the following: DSDT patching will not always work, patching the driver will work, because since 10.7 Apple programmed a "feature" into the driver. The feature is: the brightness is controlled in 16 steps from 0 to 100%. On regular boot the system uses only 12 of the 16 steps. The last 4 steps are available AFTER sleep.

Strange, but true.

Some guys got around this "feature" by sending the display right at startup&login to sleep, using a little Prog called "Sleepdisplay" from github by Kim Hunter.

 

I wanted to try it out myself and updated the system before this (chameleon und HWsensors). I disabled all modues of chameleon with Chameleon Wizard for testing purposes (like ACPI and Kernelpatcher), because I wanted to see if I really needed them.

 

After Restart: the system started up with 100% brightness like after sleep.

Since I am using "Brightness Slider" (from App Store, Freeware) as a little program in the menu bar that holds and resets the brightness to my level, the display now has & holds the brightness setting I want.

 

To make the long story short: Display brightness on my machine now seems to be fixed by simply deactivating chameleon modules. This is what i meant ;-)

 

I hope someone can reproduce and verify this...

 

Edit: I might add, that I added (just for fun my SSDT-1, compiled with MaciASL that also can extract it). I was amazed that Chameleon really loads it at boot time. In this SSDT are the Acer values for the Sensors and Powermanagement for the external components of the system. This might have also something to do with the brightness that is now available.

Hi,

 

having a few internal and external HDD here, I can say the following: No, I haven't any probs copying large files from one disk to another or for different systems (Win/Linux/OSX) to another. Also the download (like torrent files of 4-8 GB) are going fine... even after a few hours. I might mention, that I do not sent the HDD to sleep, because I am using some SDD's which do not need this feature.

 

for the Speedstepping: Like iClock said, I am also reaching here "only" 3,069 Ghz which represents the maximum that the system supports by SSDT...

ok darkness1210 what did you do to make speedstep work?

 

@wartomato What do you mean by "The Brightness on my machine is somekind of fixed"?Does it goes to full brightness native ?

i deleted all myhack.kext, patched the AppleIntelCPUPowerManagement.kext.. My SmBios is 9.2, made with ssdtPRGen.sh 35 3200 1, renamed to SSDT.aml in Extra, checked DROP SSDT in Chameleon

 

Now i have 3 steps.. 1.19GHz, 2.18GHz, 2.97GHz...

 

when i put my mobo to sleep he switches off and i need to boot again

Hi,

 

okay, I'll try to explain what I did:

 

I had the same problem and solved it here. First I got some Speedsteps by choosing the smBIOS for a MBP8,x... Before I was using 9,2 and also got only 3 Speedsteps. BUT now I am using MBP10,1 with these Speedsteps:

 

kernel[0]: AICPUPMI: CPU P-States [ 12 22 23 27 29 31 32 33 ]
 
This states that ALL possible Speedsteps on my machine are enabled - from 1200 to 3300 Mhz (which I can confirm)
 
The solution was quite simple (and states my stupidity):
  1. I disabled two modules from Chameleon (ACPIcodec and Kernepatcher). I don't need them, because Kernelpatcher is obsolete when you do not have Extensions loaded from the Extra/Extensions folder and ACPIcodec is quite old and for some unsupported machines.
  2. I extracted ALL SSDTs (SSDT as you generated and the other SSDTs that you don't see) using AIDA64 under Windows. It saves the .aml files. I renamed them and put them into the Extra folder. Open the SSDTs before copying, because SSDT.aml is not the same as your generated one (might be SSDT-1.aml) and you will need the generated one. So rename SSDT.aml from Windows to SSDT-1.aml and leave your generated SSDT.aml. rename the other SSDTs further on (SSDT2.aml, SSDT-3.aml, etc.).
  3. On reboot, Chameleon loads ALL SSDT files in the Extra folder... and voila!
I tried sleeping mode yesterday and the system goes to sleep as I wanted (Using SmartSleep utility) AND came back when I wanted. It just looses Wifi connection and the Bluetooth connection (from my mouse).
Yes, I got deep sleep and did not need to boot again. I think I could try the other sleep states the next days.
 
Perhaps you might try that.
