Apple has changed the kext for managing disks and trim, the current version of Chameleon SSD Optimizer fails to recognize and enable the TRIM for non-apple disks.
I made a temporary beta it will work with osx 10.9.4, available until it is released the final version and it can be downloaded HERE
Attention, currently has only been tested on 10.9.4 use it with knowledge of the facts
Chameleon is an optimization tool for Solid State Drive on Mac OS X system. It can enable TRIM on non Apple-branded disks. Now you can also increase durability reducing I|O writing cycles, set hibernate mode and save space disabling sleep image.
Chameleon is able to read sata system profiler info and you can easily check trim status, disk speed or properties. S.M.A.R.t. status is now supported, it's as mac shows it. Moreover you can hence control the temperature, the firmware version and more. Now you can disable the local Time Machine, the Sudden Motion Sensor or noatime set for the system, you can change sleep mode and gain space disabling the sleep image. MAVERICKS support has been added too!
Many users have chosen chameleon for their macS, we reached 125.000 downloads and more than 100.000 users! The most widely used model with ssd and trim is macbook pro, the average budget of memory is 8GB and the most popular operating system is Mountain Lion (45%) (Mavericks near 43%)
