    This video shows how to supposedly enable TRIM and successfully restart in OSX Yosemite using Terminal at the start up.

    https://www.youtube.com/watch?v=24cxJ1fCCWU

    I may try this shortly. Any thoughts on the video, think it might be safe to try?

    That video was published in July, during the beta/DP "era". The developers of TRIMEnabler have built those commands into the process of enabling TRIM with their app, no need to follow that video anymore if you're using the latest version of TRIMEnabler.

    So you're saying there should be no problem enabling TRIM in Yosemite? This is conflicting information from what I've researched so far.

    On Yosemite correct?

    I'm skeptical to try and enable becuase I've heard it won't reboot.

    I have used TRIMenabler on server Yosemite Macs with no problems, just be sure to use latest version

    Check if its enabled afterwards, if not just do it again and it will work

    I've used TRIMEnabler on both my MBP and my Mini, worked fine. It doesn't matter if you follow that video or use the latest version of TrimEnabler, you get the same result - KEXT signing is turned off so the edited AHCI/SATA driver (this is REALLY what TE does) can run.

    I understand that now. What's a bigger disadvantage: Not running TRIM or disabling KEXT?

    Kext signature checking is a new feature of Yosemite. You lasted until now without it just fine right?

    disabling the kext-signing to enable Trim is best described as taking a sledgehammer to crack a nut, and for most users it will not be worth it.

    Not sure what to take from that. I'll probably just enable TRIM, until further notice.

    Following all of the advice above...

    Trim Enabler is fine... But... Be careful once it is enabled if you need to reset PRAM and/or SMC. Switch it off before doing so. The reason for this is, it DOES corrupt the boot. I also switch off Trim when installing a new OS X update. in case it messes with the kexts and results in the same stop sign at boot.

    Other than that, I can testify that TE works fine.

    I'm running TRIM now, no problems so far. Would the lack of kext cause a security page to pop up when downloading in a browser? :apple:
