Check Activity Monitor (/Appications/Utilities) and see if there is anything hogging up your resources.

Hm...have you tried reinstalling?

 

Don't try to open anything while Activity Monitor is running. Select All Processes and see if there is anything using too much CPU/RAM.

Did you extract it from OS X or Linux?

 

If you're having problems with OS X, I can give you instructions on DSDT extraction in Linux (Ubuntu).

Okay, so now you need to get to the Terminal. If your graphics card doesn't have drivers (it's running in Classic mode) than go to the Applications menu in the top-right corner, choose Accessories > Terminal. If Unity is loaded, go to the Ubuntu icon at the top right and search for Terminal. Now type: the following commands:

 

cd ~/

sudo cat /sys/firmware/acpi/tables/DSDT > dsdt.aml

 

Bingo! You now have the DSDT in your home folder; now you can drag it onto a flash drive and upload it. :) If you want to be a dear, you can also decompile it by entering the following commands:

 

sudo apt-get install iasl

iasl -d ~/dsdt.aml

 

Then drag dsdt.dsl onto your flash drive. :)

 

You can edit it in either. It doesn't really matter. I would post this issue with your DSDT up in the DSDT forum and see if any DSDT gurus know what to do (I'm a noob to DSDT; I only know how to fix the RTClock, which is totally unrelated to your issue :rolleyes:).

I'm so sorry - I accidentally gave you the DSDT for my MacBook!!! Don't use it; I will patch the real DSDT.

 

I think the DSDT Patcher is malfunctioning...I'll do what I can.

I wouldn't worry about warnings. I'll add the patches for the SATA. :)

 

However, I'll have to send you dsdt.dsl as for some unknown reason DSDT Patcher will only compile the DSDT for the machine you're operating on. I'll be back in a little. ;)

 

It seems that the DSDT Patcher fixed all the issues listed in the SATA fix post. I only added a group of lines in the TMR device. Compile it and see if it works. :)

You don't have to do anything, just place DSDT.aml in /Extra, Chameleon loads it automatically.

 

The "Extra" folder is located either at the root of your system drive or at the root of the partition where Chameleon is installed.

thank u my friend

 

i did it in extra and i have com.apple.boot.plist and i did flag

<key>DSDT</key>

<string>/dsdt.aml</string>

 

in boot i got some Panic and alot numbers and i only can understand this :P :

Kernel extensions in backtrace ( with dependencies)

com.apple.driver.appleps2Controller

com.apple.driver.AppleAPIC

com.apple.driver.AppleACPIPlatform

com.apple.iokit.IOACPIFamily(1.3.0)

com.apple.iokit.IOACPIFamily(2.6)

 

and then restart again couple times then works with no keyboard

 

and now i use flag DSDT=none

 

 

 

Update :

 

now boot good when i used GraphicsEnabler=Yes

 

i'll test if hard disk gonna freeze or not

 

P,S: how i know if DSDT is loaded ??

Don't know how to tell if DSDT is loaded; but if it's dsdt.aml inside the Extra folder, and you didn't type DSDT=none, it should be loaded.

 

If you still get panics, I may need to remove those lines I added in your DSDT.
