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 there..

i have one question.. my osx 10.8.4 freezes after transfering data in a size about 4-5 gb. it does not matter if i make a install or download .. sometimes it freezes after one hour and i can not move mouse or anything, it's just Frozen.. does anyone have a similar problem like this ? does anyone have a awnser for this problem ? I hav Acer aspire V3 771g with i5Cpu and Geforce 710m
Also wanted to ask is there a possibility to get boost to 3.2GHz ?

Thanks in advice..
 

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.

Try the terminal script in attachment.  It works perfect on several laptops. It is especailly for Core i 2/3 .....m. No need to extract SSDT in Adia.

Howto is included.

 

Have fun.

 

Sorry, I had forgotten to attach it.

Yes, it is the script of RevoGirl RIP. I have found it, I do not know now anymore, where it had been, but it was adapted by a unknown person for Mobil Cpus. You kann believe me, it works perfekt.

 

Du kannst mir vertrauen, und es gefahrlos benutzen.

 

Have fun!

with MBP10.1 i get these speedsteps
kernel[0]: AICPUPMI: CPU P-States [ 12 22 26 27 28 29 30 32 ]

but when i watch hw monitor it gives me max x30 / 2970MHz.. i Never reached x32 to drive 3.2GHz.. How to enable x32?
my cpu is 3230M with turbo boost up to 3.2GHz

I thiink , you can reach turbo boost 3.2 GHz only, when you are using one core.

 

Have fun.

Hi,

 

from back to front.

 

Styrian and darkness: You can reach the Turbo state 3.2 Mhz, but only when all cores are at max. speed. But why worry. It is allmost not possible to reach these state on OSX with "regular" usage. I reached it one time when copying gigabytes of data, while scanning Wifi and scanning another HDD with an antivirus...

 

styrian: reads the posts. Other SSDT help with Wifi or Brightness Probs. This might differ on other systems like your Lenovo.

You totally missed it. We all used the Revogirl (R.I.P.) script or better the modified script. The Script is also integrated in MacIASL (so you really do not need the "old" script). Extracting the SSDTs helps in getting parts of the hardware in the Acer Aspire V3-771G to be better integrated in OSX, when using a custom DSDT. Parts of the IntelHD, the Nvidia, the CPU-states, etc. are in these SSDTs and not in the main DSDT. Your mentioned script is only for ONE SSDT (the CPU one) and solves ONE Problem: Steedstepping. 

 

 

Example: the 9462 Wifi card is now (with SSDTs) recognized as a unknown network controller by the system. Before is wasn't recognized at all by OSX.

 

For AIDA64: 

1. in main window, right click the status line at the bottom. A menu appears. Select ACPI Tool.

2. A new window will open with the DSDT. Click on the "Save" button under the window an choose WHAT file to save (SLIC, DSDT, SSDT, SSDT-1, etc.). AIDA saves the file as *.bin on your HD.

3. Rename the file under windows or OSX to blablabla.aml and copy it to the extra folder. Remember NOT to overwrite your script-generated SSDT as posted before.

Nice to see development on the 771g series :), As for now everything should work, except the GraphicsCard. Does someone have a Solution by just using the nvidia Card but not the Cpu Graphics without turning the Screen Black/Off at Boot ?? Is it even possible ? Because the Display on this notebook use the Cpu Graphics to display things. By disabling the CPU GFX the Screen goes totaly Black, but on the Background OSX is working, so it recognize the GPU.

Hi everybody,

 

updated to 10.8.5 today (using the combo update from Apple, approx. 831MB). Here are my notes of things to take care of before updating:

 

1. Update GenericUSBXHCI to 1.2.5. If you don't, well, the Appledriver will take over and USB3.0 ports will not work. Anyway, if you don't, DISABLE the old driver before rebooting or you will only have the touchpad working.

 

2. You will need to patch again the AppleIntelCPUPowermanagement.kext or copy the old one into /S/L/E. AICPMPatch is still working on 10.8.5 (kext version is now 214, in 10.8.4 it is 196). Otherwise the system will panic at reboot.

Right now my MBP10,1 (i7 - 2,3 Ghz) shows "kernel[0]: AICPUPMI: CPU P-States [ 12 22 23 29 31 32 ]" after startup.

 

3. You will have to reenable SSD Trim (if you have installed a SSD) by using Chameleon SSD Optimizer.

 

4. Good news. My system recognizes the display without patching and the BRIGHTNESS SLIDER shows up in the Monitor preference pane!

 

5. Update your FakeSMC (I am using kozleks version 5.3.814 right now and it seems to be working.)

 

6. Updated Chameleon to 2262 (before). My patched DSDT and the SSDTs are the same as before and working fine. I did not change the chameleon.boot.plist so this all seems to work.

 

7. Disable Geforce.kext in S/L/E after the update and before reboot. I did not test it up to now, but I think the system will have the "normal" black screen.

 

8. If you have VoodooHDA installed: You do not have to change anything. It boots fine.

 

9. Bluetooth 4.0 driver (IOath3kfrmwr.kext from Rehabman) is still working with the integrated Atheros 9462 wifi card. If anyone still has problems... it is the same since 6 years ago: Boot into win, get bluetooth to work and connect and then reboot into OSX... It works then (at least for my Bluetooth mouse).

 

@Tuning: We discussed the Geforce thing. This is just not possible without patching the BIOS, because the Acer uses the INTEL framebuffer at startup and can not change it during boot. This is a Hardware problem and can not be changed on our systems (Thanxs, Acer). The Nvidia is recognizable, bur the GPU changing routine Apple uses in their Nvidia BIOSes is different to the Nvidia one (called Optimus). Oh, the Card reader and the integrated Wifi won't work either... so these are the things that will probably never work.

 

 

Hope this helps.

Ups, stop the presses...

 

Just noticed something after reboot. USB3.0 is no longer working. 

I sent a ticket to the developer and we will see what happens ('cause I am not the only one with this problem).

 

Can anybody confirm this too?

I can confirm that usb 3.0 isnt working on 10.8.5

Ive found some interesting hda patch to work without vodoo kext. The v3-771g has the alc269 chipset and i try to get applehda to work, because it more stable and has better audioquality then the vodoo patch.

 

EDIT: USB 3.0 Work by Booting with -gux_defer_usb2

Hi,

 

I am using AppleHDA here with the HDAEnabler.dylib in Chameleon (2.2-2263) and it is working quite right. Only the HDMI outpot will not work correctly. Therefore I am using VoodooHDA again.

 

I am trying the Kernel flag right now and chatted with the developer, because entering Kernel flags should not be necessary at all... Let's see if it works.

 

Edit: the kernel flag did not work... :-(

try this http://sourceforge.n...tar.gz/download with the boot flag, hope it helps

Im working on applehda to get it to work properly. I just dont like vodoo audio at all :)

Thanx for the link, but I had it already installed. Still the same prob, but zenith432 wanted my xhcdumps for the USB3 and I sent it to him. Let's see what happens.

Hi there,

 

I thought I should share the last mail from zenith432 with you that solved my USB3.0 port problems over here:

 

wartomato,

 

Zenith432 has replied to a personal conversation entitled "devices not recognized".

 

Zenith432 said:

======================================================================

Yeah, I'm pretty sure it's the Intel idle causing the interrupt stall.  Boot with '-gux_no_idle', and it should resolve the problem.

======================================================================

 

This means that the USB3.0 ports will not be idle anymore and "waiting" for something to be plugged in and will not go into a sleep state. but all my USB2.0/3.0 hardware is now recognized again on the USB3.0 ports.

 

Perhaps this might help someone out there for the time being.
