Trim For Non Apple SSD

What is Trim For SSD

A Trim command which allows an operating system to inform a solid-state drive (SSD) which blocks of data are no longer considered in use and can be wiped internally.Trim was introduced soon after SSD’s started to become an affordable alternative to traditional hard disks. Because low-level operation of SSDs differs significantly from hard drives, the typical way in which operating systems handle operations like deletes and formats resulted in unanticipated progressive performance degradation of write operations on SSD’s

 

SSD

In other words TRIM  helps to maintain the performance of solid state drives (SSDs) at an optimal level over the lifetime of the drive. TRIM functions by actively deleting invalid data from the SSD’s memory cells to ensure that write operations perform at full speed

On this guide i will show you how to enable Trim For Non Apple SSD which gives more performance to you system

Chameleon/Real Mac User

Launch this in terminal from /Application  and type following

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

Clover Boot Loader Method

This is valid only if you use Clover boot loader. 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 delete kernel cache and rebuild using following terminal commands

sudo rm -r/System/Library/Caches* 
sudo touch /System/Library/Extensions
sudo reboot

Note:- Following guide is tested on  10.7.5 ,10.8.5,10.9.5,10.10.4 and latest El Capitan 10.11 beta 2 also this is works on both Real Mac System and Hackintosh System and it is work flawless.
