For more info on these devices, check out our complete review roundup of Thunderbolt PCIe controllers – perfect for Apple’s 2013 Mac Pro! Trim Enabler App Mac Pro Microsoft has released an update for Windows 7 that adds NVM Express support. With Mavericks, not all SSDs will report TRIM support, but doing a benchmark both before and after the change should confirm that TRIM is functional. Windows 8 and later Windows operating systems support trim for PCI Express SSDs based on NVMe, and the unmap command which is a full analog of the TRIM command from Serial ATA for devices that use the SCSI driver stack, including USB Attached SCSI Protocol (UASP). Note: In some cases, a restart may be required before TRIM shows as Enabled in the System Profiler. Then, scroll to the SATA/SATA Express section, and select your SSD. To ensure that the command was successful, and that TRIM really is enabled on your SSD, click the Finder menu in the Menu bar, then navigate to About This Mac > More Info > System Report. I don’t like to recommend third-party tools, as they often make system-level changes above and beyond those performed by the terminal command – and that may not be in your best interest long-term. If that doesn’t do the trick, you can try TRIM Enabler 3.0 or later for Mac. I recommend trying Chameleon SSD Optimizer first. If you don’t find success using the Terminal command to enable TRIM for your SSD, there are two third-party apps that can help you enable TRIM support. Using a Third Party Tool Trim Enabler App Mac 10 The above-linked document also contains some troubleshooting instructions, as well as details on how to disable TRIM support if necessary. Note: This involves the use of terminal commands, so proceed at your own risk.įirst, enter the command found in this document in the Terminal app on your Mac (found in Applications/Utilities).Īfter entering this command, you’ll need to enter a second command: In you have an SSD that supports TRIM, follow the below instructions to enable it in OS X Mavericks. How to Enable TRIM Via the OS X Terminal (Recommended) As such, TRIM support is not the trivial matter that some make it out to be (although certain manufacturers, such as Other World Computing, include firmware that eliminates the need for OS-level TRIM support). The TRIM command is an important disk command for SSDs that keeps your flash memory appropriately cycled so that you can achieve faster read and write speeds, as well as a longer lifespan for your SSD. We’ll show you how you can enable TRIM across the board. This support continues on in OS X Mavericks, but as many have noted, it only seems to work for Apple SSDs by default. Added New Features Chameleon is able to read sata system profiler info and you can easily check trim.Įver since the release of OS X 10.6.8, Apple has been selectively enabling the TRIM command for SSDs in OS X. Now you can also increase durability reducing I O writing cycles, set hibernate mode and save space disabling sleep image. It can enable TRIM on non Apple-branded disks. compared to HFS+ partitions) such as ‘containers’ before you progress.Īnyway, just adding more background in case it helps - I appreciate yours is external and Darryl has already pointed out that TRIM may or may not be supported in your case.Chameleon is an optimization tool for Solid State Drive on Mac OS X system. If you’ve never used APFS, it’s worth reading up on the new features and different structure (e.g. new drive is internal and I had booted off an external drive. I’m not sure if this was specific to my setup i.e. Basically, unexpected extra volume/names, greyed out Macintosh HD and internal drive displayed as external - turns out this is normal and these were hidden/properly labeled after re-booting. You can do this by simply searching terminal in Spotlight or heading to Applications -> Utilities -> Terminal. Main ‘surprise’ was how the disk and Macintosh HD volume were represented straight after formatting. Apple added a command called trimforce in OS X 10.10.4, allowing Mac owners using third party SSDs to enable TRIM. I did quite a bit of ‘research’ first and decided to enable TRIM using the MacOS trimforce setting after formatting as APFS with Disk Utility and subsequently restoring from a clone backup with an OS installation. FWIW, I installed a Samsung 860 EVO as an internal High Sierra system drive a couple of weekends ago.
