    I just upgraded to 10.7.3... a clean install from Snow Leopard.

    I was about to install Trim Enabler for my third-party SSD (160GB Intel G2). But checking the disk info (in Disk Utility click on SSD in left panel, then click the "Info" button), the line that used to be there for "Trim Support" is gone!

    Partition Map Scheme : GUID Partition Table
    Disk Identifier : disk0
    Media Name : INTEL SSDSA2M160G2GC Media
    Media Type : Generic
    Connection Bus : SATA
    Device Tree : IODeviceTree:/PCI0@0/SATA@1F,2/PRT0@0/PMP@0
    Writable : Yes
    Ejectable : No
    Location : Internal
    Solid State Disk : Yes
    Total Capacity : 160.04 GB (160,041,885,696 Bytes)
    Disk Number : 0
    Partition Number : 0
    S.M.A.R.T. Status : Verified

    Does this mean that TRIM is already enabled?
