Some user have trouble after copying the kext.
 
In toto there are 4 methods to enable TRIM (use only one):
 

Important: Add "kext-dev-mode=1" as Kernel Arguments or the computer won't boot.

 

1st Method (Obsolete. Use 2nd or 4th instead)

Copy the kext, delete kernel cache in /System/Library/Caches/com.apple.kext.cache/Startup/ and launch the following command in terminal:

sudo touch /System/Library/Extensions && sudo kextcache -prelinked-kernel /System/Library/Caches/com.apple.kext.caches/Startup/kernelcache -K /System/Library/Kernels/kernel /System/Library/Extensions

Then reboot normally.

 

2nd Method (For real Mac or Chameleon users)


Launch this in terminal (are 4 commands):

sudo cp /System/Library/Extensions/IOAHCIFamily.kext/Contents/PlugIns/IOAHCIBlockStorage.kext/Contents/MacOS/IOAHCIBlockStorage /System/Library/Extensions/IOAHCIFamily.kext/Contents/PlugIns/IOAHCIBlockStorage.kext/Contents/MacOS/IOAHCIBlockStorage.bak

sudo perl -pi -e 's|\x00\x41\x50\x50\x4c\x45\x20\x53\x53\x44\x00|\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00|' /System/Library/Extensions/IOAHCIFamily.kext/Contents/PlugIns/IOAHCIBlockStorage.kext/Contents/MacOS/IOAHCIBlockStorage

sudo touch /System/Library/Extensions

sudo kextcache -prelinked-kernel /System/Library/Caches/com.apple.kext.caches/Startup/kernelcache -K /System/Library/Kernels/kernel /System/Library/Extensions

3rd Method (Clover only)
 

This is valid only if you use Clover bootloader. Add manually the KextPatch in config.plist:

<key>KextsToPatch</key>
		<array>
			<dict>
				<key>Name</key>
				<string>IOAHCIBlockStorage</string>
				<key>Find</key>
				<data>
				AEFQUExFIFNTRAA=
				</data>
				<key>Replace</key>
				<data>
				AAAAAAAAAAAAAAA=
				</data>
				<key>Comment</key>
				<string>TRIM Enabler</string>
			</dict>
		</array>

And reboot. No kernelcache to rebuild!

 

If you use Clover Configurator you can follow this steps:

  • go to Kernel and Kext Patches add a new row
  • in name put IOAHCIBlockStorage
  • in find hex put 004150504C452053534400
  • in replace hex put 0000000000000000000000
  • in comment you can write what you want (a description for example)
  • in InfoPlistPatch leave it as is (unchecked)
  • Save and reboot.

Or you can follow this video:

 

4th Method (Mac and Hack)
 

Download this app http://www.insanelymac.com/forum/files/file/329-trim-enabler/ and run it.

Can you post the description of the error? Use the 3rd method if you have Clover.

So impatiently I tried doing this without fully understanding the commands and steps.  My Macbook ended up not being able to boot.  That "Do Not Enter" or whatever its called sign came up.  I ended up having to go into Recovery mode and inputting more commands to get the macbook bootable.  I can now use my computer but at every boot up I have a gray loading bar.  It's not that slow so it's not an issue with waiting but from what I've read it's not normal for that to appear from a cold boot or restart.  What do you guys think the issue is?

In the first method you can restore the backupped kext and rebuild kernelcache. With second method you can restore the backupped binary file. With third, you can't sue third in original mac, you simply delete the string in config.plist.

 

I think you have followed the second one. Il not restore all files and follow the second method.

I put the third method in the config.plist for Clover on my USB drive witch is going to install Yosemite Beta on my SSD.

I can see that TRIM is enabled via the System Information.

 

I'll tell you later if it still the case after the installation.

 

Thanks for your methods.

I used Trim Enabler 3.2.5 for Yosemite public Beta.. the first time I turn on Trim.. the app will modify com.apple.boot.plist to add kext-dev-mode=1

The Trim then works. However on every boot, there is a 5 second delay (this computer encountered errors in boot and will wait five seconds). 

 

To fix it, 

- should add the Kext-dev-mode=1 using Clover config or com.chameleon.boot.plist on Extra (do this immed after install Trim Enabler and before restart... or your system will not boot).

- delete the com.apple.boot.plist in /Library/Preferences/SystemConfiguration/com.apple.Boot.plist

- rename the com.apple.boot.plist-org back to com.apple.boot.plist

 

the error is due to Trim Enabler was not expecting an Hackintosh. and it modified apple.boot.plist wrongly.

Thank you for the intel !

I've no use of Trim Enabler on Yosemite since I use Clover to modify via the KextToPatch a string for enabling Trim.

for those who had it fatal screen on them. if you kept the installer (on a different drive) you can go back into the base system.dmg and pull the altered file from the extensions folder to repair the install.

 

I always backup the installer on a thumb drive before installing a beta OS, it has saved my Bacon more then once... mmm Bacon, time for breakfast. ;)

none of the methods here.

 

 

***

replaced with this kext and Trim works, thx to Marchrius :w00t::thumbsup_anim:

I'm happy to read that! At next update if you use Clover you can use the 3rd method that is more flexible and don't need to replace any kext.
