Permanent SOLUTION for the WHINE issue. STEP by STEP Instructions.

Question

Hi all,
Your dreams have come true. There is a cure for the whine that requires no programs to run and persists between reboots.
It requires the editing of one file. Please attempt this only if you understand what you are doing. I take no responsibility for your actions.
Here are the steps:
1. Find the file: -> System -> Library -> Extensions -> IOPlatformPluginFamily.kext
2. Click the file and choose DUPLICATE from the File menu. Drag the copied file to somewhere safe.
3. Control click the original file to get: SHOW PACKAGE CONTENTS
4. Double click CONTENTS
5. Double click PLUGINS
Delete everything except:
ACPISMCPlatformPlugin.kext
Simple_PlatformPlugin.kext
6. Control click ACPISMCPlatformPlugin.kext and again SHOW PACKAGE CONTENTS
7. Double click CONTENTS
8. Open the file: Info.plist with a text editor. I use Subethaedit.
9. Look for the following:
<dict>
<key>DTC_WAB</key>
<integer>10</integer>
<key>DTC_WAT</key>
<integer>0</integer>
<key>GTC_WAB</key>
<integer>15</integer>
<key>GTC_WAT</key>
<integer>15</integer>
</dict>
</array>
<key>model</key>
<string>MacBookPro1,1</string>
Make sure the MacBookPro1,1 is there at the end of the block. The block above represents the CPU throttling values. You'll notice that the integer values in the last block are 10 / 0 / 15 / 15
There are other similar blocks related to other machine types. The first block is for "M9ADP1,1". The MacBook Pro Block is the second big block.
The important line numbers are 129 and 131. So look there.
Change those to:
<dict>
<key>DTC_WAB</key>
<integer>10</integer>
<key>DTC_WAT</key>
<integer>0</integer>
<key>GTC_WAB</key>
<integer>0</integer>
<key>GTC_WAT</key>
<integer>5</integer>
</dict>
</array>
<key>model</key>
<string>MacBookPro1,1</string>
So you have 10 / 0 / 0 / 5 in the integer values.
10. Double check things and then save the file.
11. Reboot to a no whine machine.
12. Enjoy.
With this method the only change is to the throttling matrix retaining all the code of the kernel extension relating to the MBP otherwise.

Answer 1

1. The other files pertain to other Mac types and not the MBP; I don't think they'd harm anything by being there but it's what I have and I just wanted to report my setup exactly and remove all other variables.
2. If you look at the matrix, the first number appears to relate to overall processor load; so it gives parameters for various thresholds.
All the values above are identical X / 0 / 0 / 15; where X represents the processor load threshold.
When this matrix is assigned to the final ie. 10 level ie: 10 / 0 / 0 / 15 there is a very slight hiss still audible. Changing to the given values 10 / 0 / 0 / 5 eliminated all whine on my machine.
I agree it would be best to know what the values mean but I've just used my best deduction to work out this strategy.
Regards.
