Users who installed their own SSDs had to hunt down third-party tools that enabled TRIM in an unsupported way. Historically, Mac OS X has only enabled TRIM for the solid-state drives Apple provides. Windows 7 and newer have had built-in support for TRIM, which they enable for all SSDs. This can improve the performance of your Mac, as well as extend the life of your SSD. It is a utility that enables the trim feature on your Mac’s solid state drive (SSD). The SSD can then manage its available storage more intelligently. Jayma Novem0 65 8 minutes read If you are a Mac user, then you have probably heard of Trim Enabler. TRIM ensures the physical NAND memory locations containing deleted files are erased before you need to write to them. This causes your SSD to slow down over time unless TRIM is enabled. With flash memory, it’s faster to write to empty memory - to write to full memory, the memory must first be erased and then written to. The SSD knows that the file is deleted and it can erase the file’s data from its flash storage. It can enable TRIM on non Apple-branded disks. ![]() When an operating system uses TRIM with a solid-state drive, it sends a signal to the SSD every time you delete a file. Chameleon is an optimization tool for Solid State Drive on Mac OS X system. RELATED: Why Solid-State Drives Slow Down As You Fill Them Up 1 Having enabled trim on recent OSs after installing an SSD using the Terminal command sudo trimforce enable, I assumed it would be an easy fix on OS Lion 10.7. Note that no downloads of TRIM Enabler are hosted here.Why TRIM is Important, and Why Macs Don’t Always Enable It by Default 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. There are two apps that we can download that does the job Show. Third party SSDs never have TRIM enabled. 23 Share 4.3K views 2 years ago This video is about enabling TRIM on different branded SSDs that we install on Macbook Pro or Macs. 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. Some people claim that, since it’s blacklisted in Linux systems, TRIM should never be enabled in Mac OS X systems for Samsung 8xx SSDs. 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. As you may know there are opposing arguments on enabling TRIM on Mac OS X systems. 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. Please make sure your drive has the necessary firmware version in order to. 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. Any SSD (internal or external) with Trim support should work with Trim Enabler. There are no other downloads of the old 2.2 version available. 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. 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. ![]() TRIM is critical for SSD health over time. TRIM tells the SSD that data in a block is no longer needed. How to Check and Enable TRIM on a Mac SSD Wie überprüfen und aktivieren Sie TRIM auf einer Mac-SSD SSDs vs. 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. Flash memory doesn’t work like a normal disk it can be written in “pages” (small, i.e. To enable TRIM, first save all your open documents as this will reboot your Mac. 4KB) but can only be erased in “blocks” (a set of many pages, i.e. 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. 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.
