Hello,

After OS-X Yosemite 10.10.3 update "TRIM" support for SSD is no longer working.

I tried reappling "TRIM" support from the Multibeast installer however it no longer appears to be working.

I selected from Multibeast the following options:
TRIM support
3rd party sata support
Intel Generic sata support

Which has worked for me in the past. Now no longer works.

Open terminal and digit this:

Code: 
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

then.. rebuild permission & cache and reboot !
Trim works again !
 
How do you "rebuild permission & cach" ?

-Thanks

Click to expand...

I also entered the second command suggested in this post:
http://www.tonymacx86.com/os-x-updates/161314-os-x-10-10-3-update-6.html#post1017430

Fixing permissions with OSX's Disk Utility should be enough ...

After the two commands TRIM works for me again :)
 
I tried it with both commands and rebuilding permissions and repairing disk.

With "NO" success.

Any more ideas?
 
Thanks, it worked.

I installed from Multibeast Yosemite app the following:
3rd party sata support
Intel generic AHCI Sata
TRIM support

Reboot computer

Start computer and

Open terminal

and enter code:

Code: 
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

and Reboot computer

Works fine now.
