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

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:

ACPI_SMC_PlatformPlugin.kext

&

Simple_PlatformPlugin.kext


6. Control click ACPI_SMC_PlatformPlugin.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:


DTC_WAB
10
DTC_WAT
0
GTC_WAB
15
GTC_WAT
15


model
MacBookPro1,1


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:


DTC_WAB
10
DTC_WAT
0
GTC_WAB
0
GTC_WAT
5


model
MacBookPro1,1


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.
