    I have my first SSD on its way (Samsung 830 256 GB), and I have been looking into enabling TRIM.

    I saw in one thread someone suggested the advice from this page, which gives instructions on how to enable TRIM via the Terminal:

    As you can see on that page, the person giving the advice is very adamantly against the app called Trim Enabler saying that it replaces a kernel extension rather than patching it, which is apparently a bad thing. However, he's referring to Trim Enabler 1.x and there is now a 2.x version. I can't see anything on the Trim Enabler web-site on how the application now works.

    So, I was wondering what people in the know think about this? Frankly I feel a bit uncomfortable using an unofficial solution either way, but I understand that TRIM with 3rd party SSDs will always be unofficial on Macs, so I just want to find the cleanest way of doing it.

    Thank you.

    I know Chameleon SSD Optimizer uses patching, not replacing, and the FAQ shows you exactly how to patch manually, I trust it, the developer is communicative and very quick with updates (as you have to re-enable TRIM support after almost every update)

    I'm pretty sure the newer Trim Enabler patches the kernel extension, but I prefer Chameleon.

    One of the issues with using the trim enabler app is trust.

    The developer may well have made things right now by copying what Grant Pannell did, but initially his hack was atrocity.

    And given the lack of any details now, as you noticed, I cannot fathom why people just jump into the use of this application.

    If you feel the need to do this, do it manually so you understand what the hell you have done.

    You are messing around with stuff which can break your system.

    Thanks. I like that Chameleon lists the way to do it manually. I'll just do that.

    I also have a Samsung 830 256GB on the way for a 13", this will be my first SSD as well. Is this Trim thing absolutely necessary?

    I've had my crucial SSD for six months now without trim and have no problems. Garbage collection has done a good job so far. Samsung supposedly has good GC as well.
