Yosemite and TRIM

tried to enable trim and now macbook pro won't boot for me either. can i use target disk mode to transfer something from it that i didn't back up to my imac before i restore? the last i backed up was a month ago so i won't lose TOO much lol

That's interesting to know that third-party TRIM enablers aren't working, at least yet. So it's also confirmed that OS X isn't supporting the third-party SSD's with TRIM either eh?
 
I would hope they would, but I'm not expecting to see third party SSDs have TRIM enabled.
 
I wouldn't hold my breath for official support neither, but I'm sure TrimEnabler will be updated to work with Yosemite.
 
Hi, developer of Trim Enabler here.

Status of Trim in Yosemite:

  1. Yosemite still limits Trim to Apple only SSD, like other OSX
  2. Trim Enabler runs fine and seems to add Trim support just like before
  3. Kernel extensions that have been modified are no longer loaded by OSX, so you will get a boot failure after enabling Trim

Working to get around this, I have every intention of supporting Yosemite for Trim Enabler.

If you want to folllow the progress and get support, the cindori.org topic posted above is where I'll be.

I know that modern SSDs have redundancies and other tech to limit the degradation from not using/having TRIM, so I'm not particularly worried, in the short term!

Looking forward to your Yosemite release, and am hoping it'll be before we move to DP2.
 
It has worked for me, but after booting the Mac a few days later, the same "no-go" sign appeared.

Not sure if it is due to having trim support enabled or something else... :confused:
 
There's a known bug that when TRIM is enabled, the Mac will fail on the next reboot... so be careful...

Mine also died, had to Cmd+R and go into Terminal to do the fix:

Code: 
Run these commands, replacing YourDisk with the name of your Mac disk

rm -rf "/Volumes/YourDisk/System/Library/Extensions/IOAHCIFamily.kext"

cp -r "/System/Library/Extensions/IOAHCIFamily.kext" "/Volumes/YourDisk/System/Library/Extensions/IOAHCIFamily.kext"

touch "/Volumes/YourDisk/System/Library/Extensions"

kextcache -u "/Volumes/YourDisk

Did you experience the boot failure after the fix from Cindori?

It is not really a bug, apple decided to not load unsigned kexts which leads to this mess.
