Thanks a lot I did not have success using Groths Trim Enabler with 2012 MacBook Pro with Mountain Lion 10.8.2 and a Samsung SSD 840 Pro 512 GB. To re-enable the Sudden Motion Sensor in Mac OS X 10. Here's how to find out if TRIM is running or not. 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 But only on Apple SSD brand So I made this patch to enable TRIM. 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. In recent OS versions for Macbook Pro 2011 though, and in Lion, there is support for TRIM. View the virtual memory currently in use: $ sysctl vm.swapusage While TRIM does become enabled, the kernel extension you now have has the potential to cause a ton of problems. Turn off the system swap can also improve performance. This means that when you use TRIM Enabler with Lion, it replaces a critical kernel extension, with lots of dependencies, with an older one (from Snow Leopard 10.6.8). 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. The app is called TRIM Enabler and it works by loading a kernel extension from MacBook Pro 2011 models (with TRIM support) into your Mac OS X kernel, this forces TRIM to be enabled. 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. SSD optimization tool on Mac OSX and TRIM enabler, you can change hibernate mode and sleep image, set NOATIME. 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.
