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.
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. However, our testing has shown no issues with using Trimforce or third-party enablers with an OWC SSD.
If you would like to enable TRIM on your SSD with the Trimforce command, we have put together a brief step-by-step guide:
1.) Open Terminal. 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”. While more recent SSDs shouldn’t have a problem enabling TRIM via Trimforce, older SSDs might behave in unexpected ways when enabling TRIM. However, if you have a relatively recent SSD, there shouldn’t be any problem enabling TRIM via Trimforce. As a reminder, you should always keep a backup of your data to ensure your data is secure. If users already have applications such as “Trim Enabler” already installed, they should probably remove it before using Trimforce.3.) You’ll be asked “Are you sure you wish to proceed (y/N). 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. Is this okay (y/N) ?” Press y again and enter and it will tell you “Enabling TRIM”. Note: After your machine reboots, Terminal may relaunch depending on your machine’s settings. If that happens, you can simply close the window.
