Almost all SSDs do logical block-level deduplication internally to boost performance, and a logical block that is a duplicate can be replaced with a simple pointer and its data pages freed, the latter of which is the same thing that TRIM triggers.
One more thing: there is a workaround to do a TRIM when it’s totally unsupported. 120GB drives really have 128GB of storage with 8GB of it over-provisioned, while 128GB drives have no over-provisioning and need TRIM desperately.

Over-provisioning is where a drive has more capacity than it makes available to the user, and SSDs use this extra space as a spare work area, which becomes extremely important if the drive is full or TRIM is disabled (which is not much better than the drive being full). Once every logical block has been written to once, the only available space the drive has to garbage collect with is the over-provisioned space, if it has any of that at all. Without TRIM, any logical block on the SSD that is written to becomes permanently “used” to the drive’s controller, so even if the file whose data is stored within is deleted, the data block still has to be treated internally within the SSD like it’s still in use.
TRIM is how the OS says “I’m not using this data anymore, so you can mark it as free,” so getting TRIMmed is a vital component of the SSD’s garbage collection system, not just a nice-to-have feature that magically speeds things up. It is common for a flash block to end up with some pages used and others free, and the drive tries to get ahead of user demand by garbage collecting (consolidating) these partially filled blocks into a smaller number of blocks (that have a lot more data per block), then erasing the newly freed blocks so they’re ready to go if a big burst of disk writes comes in. 4KB) but can only be erased in “blocks” (a set of many pages, i.e. Flash memory doesn’t work like a normal disk it can be written in “pages” (small, i.e. Without TRIM, the drive can’t clean itself up internally because it has to assume that any block which was written is still needed, and depending on the amount of over-provisioning in the drive, you could end up in trouble without TRIM. TRIM tells the SSD that data in a block is no longer needed. TRIM is critical for SSD health over time.

I’m sharing this link to the old software to help fellow aging Mac enthusiasts out.ġ0.6 10.6.8 2.2 2006 Apple iMac Mac Mac Mini Mac OS X OS X Snow Leopard TRIM TRIM Enabler Post navigation Then I scanned the Internet Archive’s Wayback Machine and found a working DMG for TRIM Enabler 2.2 in there. I’m upgrading a machine stuck on 10.6.8 and I didn’t want to pay for what was once a 100% free program. There are no other downloads of the old 2.2 version available.
#Trim enabler for hackintosh download#
However, sometime in 2014, the author of TRIM Enabler made it a paid program and took away the free download for TRIM Enabler 2.2, opting to only make it available if you bought a newer version despite TRIM Enabler 2.2 being totally free to download and use.
The tool of choice to do this for several years was called TRIM Enabler, with the last version supporting OS X 10.6 “Snow Leopard” being TRIM Enabler 2.2, the holy grail of flipping the TRIM switch on older OS X versions.

What do you do if you’re on an older version of OS X? Well, Apple doesn’t give you trimforce on older versions, so the only answer is to “hack” the storage driver in OS X to bypass the check. There is an exception: in Mac OS X 10.10.4 and later have a command you can run in a terminal called “trimforce” that will enable TRIM support for ALL SSDs, not just Apple SSDs. Third party SSDs never have TRIM enabled.

You can get it from the Wayback Machine instead: Download TRIM Enabler 2.2 from The Internet ArchiveĪpple added TRIM support to Mac OS X in Snow Leopard update 10.6.7, but it only works on Apple SSDs.
If this simple definition is still not enough for you, jump over to Wikipedia where you will find a lot more.Note that no downloads of TRIM Enabler are hosted here. If you bought a Mac with an Hard Disk Drive or a SSD and you replaced it with a third-party SSD, or you have an Hackintosh, follow this post and we’ll get Trim fixed!īefore we begin, I know you heard somewhere that Trim is great for SSD performances and that it can increase the durability of them but, do you know what Trim actually is?īecause low-level operation of SSDs differs significantly from hard drives, the typical way in which operating systems handle operations like deletes and formats resulted in unanticipated progressive performance degradation of write operations on SSDs. Trimming enables the SSD to handle garbage collection overhead. Note: If you bought your Mac with an SSD already installed this tutorial post is not for you, in fact Trim is already and automatically enabled by OS X for you since you’re using an original Apple SSD.
