Trim For Ssd Mac Yosemite

Ssd drive for mac

I made a post earlier today highlighting some issues with using Trim Enabler on OS X Yosemite Developer Preview. Good news:Trim Enabler works to enable Trim in Yosemite, no update required! Background story: In the Developer Preview 1, modified kernel extensions are blocked from loading during boot. However, Apple also provided a way to disable this block, by simply adding a boot argument. According to Apple, this block was added for “Developer Preview 1”. which leads me to believe that this block may be removed in the final release of Yosemite. So at this point it seems likely that Trim Enabler will work “out of the box” without this boot argument for the final Yosemite release. But since some users are already using DP1 in their systems, here is a guide to enabling Trim in OS X Yosemite Developer Preview 1 using Trim Enabler:

  1. Remove your current Trim Enabler and “org.Cindori.AuthHelper” in /Library/PrivilegedHelperTools, and redownload the app
  2. Add this boot argument to remove the kext block (run in Terminal):
  3. Reboot
  4. Enable trim using Trim Enabler
  5. Wait ~1 min
  6. Rebuild kext cache manually using this command in terminal (wait for it to finish):
  7. Reboot again

Apple added a new command named “trimforce” from OS X 10.10.4 and OS X 10.11 (El Capitan).
To run trimforce type the following command into the terminal window : sudo trimforce enable

Ssd

“Trim is an operating system-based command for SSDs that is activated when you delete a file on the SSD. When you delete a file from your computer, Trim notifies the SSD that the location of the deleted file no longer contains valid data.

Thanks to you all for the help in testing Chameleon on Yosemite 10.10.3 and for your support, I really appreciated it !

  • So a foolproof way to do this is to simply: 1- Put the new SSD in the enclosure and use Carbon Copy Cloner to clone the OS and all my files to the SSD. 2- remove the HDD and install the SSD? Im just concerned that once Yosemite is on the SSD (with TRIM enabled) it will not work.

Chameleon is an optimization tool for Solid State Drive on Mac OS X system. It can enable TRIM on non Apple-branded disks. Now you can also increase durability reducing I O writing cycles, set hibernate mode and save space disabling sleep image.
