I just bought a new SSD and installing a fresh OSX onto it and wondering if I need or should install Trim Enabler? Some stuff I read online says that you don't need it with an SSD, other articles says yes, wondering what your thoughts were on this?
I just bought a new SSD and installing a fresh OSX onto it and wondering if I need or should install Trim Enabler?
I was looking for this thread, I guess it was moved, I didn't know if I had the right category or not:/ I'm using Snow Leopard (2011 MBP) on one computer and Mountain Lion (2011 MBA) on the other both fresh installs yesterday and no other programs uploaded to it yet. My question wasn't answered on MacRumors, I've gotten zero usable information from there so far.

For those early versions of Mac OS X, I used Trim Enabler.
@RadDave, as Harry said in post #2, System Profiler will be able to tell you, if trim is enabled on those external drives, provided you are using a later version of OS X/macOS.
I believe, with Mac OS X Lion and Mountain Lion, maybe Mavericks and Yosemite too, trim is not enabled.
I used it when it was needed, but then Apple added that ability back into OS X/macOS, so it really depends on the version of the OS you are using.
Ian, I don't have an external SSD to test with. But if you look in System Profiler, then select how the external drive is connected, either Thunderbolt or USB.
I did just find this old question on Tom's Hardware, TRIM on external SSD - Storage - Tom's Hardware, from 2015. It explains that Trim is a SATA command, and not used on external drives at that time.
It's a very difficult question to answer because it depends on the version of the Mac OS you are running, and the make and model of your SSD. There are a number of possible answers and a lot of confusion because things are different for each SSD you might purchase. (I wrote an article on the lifespan of SSD's and it was a quagmire trying to figure out what SSD's needed what sort of TRIM.)
The short answer is YES, every SSD needs some sort of TRIM running. TRIM will drastically increase the lifespan of your SSD.
However, some SSD's use the Mac's built-in TRIM (assuming that you are using a version of the Mac OS that offers TRIM at all, and no, not all versions of the Mac OS do: while other versions of the Mac OS only offer TRIM compatible with certain SSD's), others require a third-party TRIM, and still others provide TRIM through firmware.
You didn't say which SSD you have. I could ask you which you have, and find out from the manufacturer's Web site and/or the vendor's Web site and tell you which sort of TRIM your SSD requires with your version of the Mac OS. (Actually, you probably should have found this out prior to purchasing an SSD.) But you can do that legwork just as easily as I can. If neither the manufacturer or the company you purchased your SSD from are helpful, come back here and let me know what they had to say, and I'd be happy to get to the bottom of it for you.
Thanks Randy and to all that gave alot of good information here. I will look into ferrarr's cindori link and thanks for that. Here are the links to the SSD's that I bought if this helps for any compatibility issues;
