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. 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. Even during the ten years I spent in the Dutch Merchant Marine (the GHV), the number of acronyms was limited to ad vanced equipment that eventually became known as RADAR, LORAN, and DECCA.Note that no downloads of TRIM Enabler are hosted here. When attending high school (the HBS) after the war, my knowledge of acronyms grew slowly. Most of the newly acquired three-and four-letter abbreviations referred to organiza tions, such as the broadcasting corporations in The Netherlands and Belgium, and references to coWltries such as the USA, USSR, and UK. Gradually the daily use of acronyms grew. There was, of course, the well-known acronym associated with the nT, but at that time I did not realize that it meant more than the postal service, in those years a deteriorated service. (All acronyms used in this introduction are listed in this dictionary.) To me the meaning of"BBC" was that we would receive different information about the war than we got from the usual censored broadcasts.
My father proudly annoWlced one day that, despite the ban imposed by the occupying administration, he had managed to get a radio installed and could receive the BBC. My first encoWlter with acronyms took place when I was ten years old and growing up in an occupied COWltry during the Second World War.
