    I just ordered a 2012 Mac Mini core i5 2.5ghz model with a 500gb hd. I have been reading the tutorials on installing an after-market SSD and using it as the boot drive and to run apps, while using the original 500gb hd for storage.

    I know I can handle the install, but my question is from what I've read it sounds like after-market TRIM support has been rendered unusable with Yoseimte, unless you want to disable some security features.

    Can anyone advise? Thanks!

    Some SSDs such as the Intel 530 series and OWC's do not require TRIM.

    TRIM does a background garbage collection of sectors of deleted files. Since a boot/application drive is mostly read and seldom written the lack of TRIM support won't be that much of an issue.

    You can also buy a drive with a Sandforce controller which is designed to be used without TRIM. See http://blog.macsales.com/11051-to-trim-or-not-to-trim-owc-has-the-answer

    there will always be an update for trim enabler as there are so many aftermarket SSD out there, so you don't need to worry

    It depends on the controller used in the SSD, not the SSD supplier. You would have to find the controller used by Samsung. Note that no drive requires TRIM, but that write performance over time will deteriorate without TRIM without a Sandforce controller. Also consider if the drive is used solely for system and application programs very little writing is performed, so TRIM won't make a noticeable difference anyway.

    At some point, Apple could disable disabling kext-signing.
    Hopefully they don't - I've got a Crucial 500 GB SSD in my 2012 i7....

    But it's a worrying thought.

    Not necessarily. The problem is the use of kext signing in Yosemite and I for one can't see Apple lowering system security to make the small percentage of system tinkerers happy. So now you're talking finding a workaround. That's not always straightforward.

    And the logic about because: aftermarket SSD's out there doesn't hold much water as it's not something Apple's ever sold so they could care less about support. It's not part of their ecosystem so it doesn't count..
