Someone with a non-Apple SSD who has installed the beta could check...
I highly doubt it.
Add me to the list. It shows a forbidden icon on startup after trying TRiM enabler.
Restoring backup from TM, 6h left....
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
Here's how to fix it without full restore:

Would be nice if I could boot in recovery mode ....

Hold that thought! It works

Hi, developer of Trim Enabler here.
Status of Trim in Yosemite:
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.
Status of Trim in Yosemite:
- Yosemite still limits Trim to Apple only SSD, like other OSX
- Trim Enabler runs fine and seems to add Trim support just like before
- Kernel extensions that have been modified are no longer loaded by OSX, so you will get a boot failure after enabling Trim

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.
Update: Trim Enabler works in OSX Yosemite!
But it seems that for Developer Preview, you have to add a boot argument.

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...

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