![]() Here’s something else for the kext-wary and the terminal-command wary: Cindori has announced updates allowing TRIM without disabling kext signing for easier 3rd party SSDs without using terminal AND–they claim–it can be done in 10.10.3 Yosemite and El Capitan 10.10.4 with their TRIM enabler 3.4 and latest Disk Sensei state: Hurray! This was a loooong time coming! I’m excited because it means I and other mac users can have the security if kext signing, duraWrite, garbage collection, over-provisioning AND TRIM with my OWC SSD! I suspect it will also increase your SSD sales with kext-wary customers. If that happens, you can simply close the window.įor more information on TRIM and your OWC SSD, please read our article, With An OWC SSD, There’s No Need For TRIM Note: After your machine reboots, Terminal may relaunch depending on your machine’s settings. Is this okay (y/N) ?” Press y again and enter and it will tell you “Enabling TRIM”. Press y and then enter to proceed to the next instruction. You’ll then be told that “Your system will immediately reboot when this is complete. 3.) You’ll be asked “Are you sure you wish to proceed (y/N). If users already have applications such as “Trim Enabler” already installed, they should probably remove it before using Trimforce. As a reminder, you should always keep a backup of your data to ensure your data is secure. However, if you have a relatively recent SSD, there shouldn’t be any problem enabling TRIM via Trimforce. While more recent SSDs shouldn’t have a problem enabling TRIM via Trimforce, older SSDs might behave in unexpected ways when enabling TRIM. 2.) Enter the command “sudo trimforce enable” (without quotes). You’ll then need to enter your password to continue. You will see the screen below with a warning or “Important Notice”. If you would like to enable TRIM on your SSD with the Trimforce command, we have put together a brief step-by-step guide:ġ.) Open Terminal. However, our testing has shown no issues with using Trimforce or third-party enablers with an OWC SSD. OWC SSDs are built to run at optimal speed and provide peak performance throughout their lives without TRIM through DuraWrite technology, over-provisioning, and garbage collection. To re-enable the Sudden Motion Sensor in Mac OS X 10.On Wednesday, we reported that Apple released the latest OS X version with 10.10.4, which adds the support of TRIM for third-party SSDs. To disable the Sudden Motion Sensor in Mac OS X v10.4 and later: $ sudo pmset -a sms 0 This is to prepare for the HDD, the purpose is to shut down the hard drive when the notebook to vibration monitoring to protect the data, for the SSD, this is not required. If you install the SSD in the HDD hard drive location, you can turn off hard disks sensor. Mac notebooks: About the Sudden Motion Sensor If the system is found to be unstable, then re-open the virtual memory: $ sudo launchctl load -w /System/Library/LaunchDaemons/_ist $ sudo launchctl unload -w /System/Library/LaunchDaemons/_ist Vm.swapusage: total = 512.00M used = 0.00M free = 512.00M (encrypted)Īfter closing the virtual memory system that retains those used for virtual memory swap file can be deleted. View the virtual memory currently in use: $ sysctl vm.swapusage Turn off the system swap can also improve performance. Ars Technica points out that running TRIM prompts a "scary" message from the system, but notes it's largely because each SSD implements TRIM in a different way, with older disks sometimes acting in a way OS X would not expect.Īdvised to turn off the system's virtual memory (Swap), avoid frequent writes. To enable TRIM, a user just has to type sudo trimforce enable into the Terminal window. This means that Mac users looking to install an after-market SSD in a machine originally intended for spinning disc hard drives would run into trouble without the help of other third-party tools. Most modern operating systems support TRIM but for Apple's OS X, it has only included support for its OEM SSDs. ![]() In the absence of TRIM, users can see significantly slower drive writes as the drive begins to fill up. TRIM is a system-level command that allows the operating system and the drive to communicate about which areas of the drive are considered unused and thus ready to be erased and rewritten to. Called trimforce, the utility can be executed from the OS X terminal, and it requires a reboot to start working. OS X 10.10.4 Supports TRIM for Third-Party SSD Hard Drives. With the flip of a switch you can improve the speed and longevity of your Solid State Driveĭownload from Cindori Software Official Website /trimenabler ![]() Trim Enabler is the first and safest utility for enabling Trim in Mac OS X. ![]()
