You can do this by typing "cd " (without quotes) and then droping the amd_insn_patcher directory from finder into the terminal and hit enter.

-Type the following commands one line at a time:

cp /usr/lib/dyld ./dyld.orig
cp /usr/lib/system/libsystem_kernel.dylib ./libsystem_kernel.dylib.orig
./amd_insn_patcher dyld.orig dyld.patched
./amd_insn_patcher libsystem_kernel.dylib.orig libsystem_kernel.dylib.patched
chown 0:0 dyld.patched
chown 0:0 libsystem_kernel.dylib.patched
chmod 755 dyld.patched
chmod 755 libsystem_kernel.dylib.patched

Now open 2 more terminal tabs and type sudo su (otherwise your system may freeze in the next step! )
In the first tab type:
mv dyld.patched /usr/lib/dyld

In the second one:
mv libsystem_kernel.dylib.patched /usr/lib/system/libsystem_kernel.dylib

and in the third:
update_dyld_shared_cache

Now you are done!
