    After installing my SSD, I enabled TRIM support with TRIM enabler, but a friend told me not to do so because it used an old kernel extension and my disk maybe had built-in TRIM support.

    I Google'd a lot and I still don't know if I should enable TRIM with a software solution...

    Here is a solution that does it without using an older .kext:

    I have used this on my system and it works fine. You need to re-do the process after a new release, i.e. from 10.7.3 >> 10.7.4.

    Some will argue that you do not need Trim enabled at all as the drive will take care of it's own clean-up. But, my thought is if Apple enables Trim, then I am going to enable Trim.

    I installed it and it fixed another of my problems: my Mac was taking 20 seconds to shutdown. Now it takes 1!

    Actually it didn't solve my problem (20 sec. shutdown). I think I'll have to start another thread related to this problem some day...

    I too have the 20 second shutdown problem, and I thought that this Trim Enabler solved it, but I guess not... :(

    If you start a thread about the shutdown problem, I will definitely follow it for a solution to the 20 second shutdown problem with Lion.
