Hey all,
See Trim Enabler must still be readied for Yosemite.
That still a biggie?
Also - would appreciate some help on qetting these "Quickview"(?) items out of my Dock...

Any suggestions from the old hacks would be greater appreciated!
Force quit and restart did the trick with the Dock.

Trim Enabler 3.3 works. I've done it on my MBP. It disables kext signing, which Yosemite has now introduced. After installing, once you "flip the switch" to enable, it will reboot, then you need to open it up again, enable it once more and reboot one more time.

Oh wait... Whole bit of info over here about it, specifically the fact that turning it off is system-wide... Not entirely clear, but does it get turned off, then switched on again the 2nd time? That last bit is a bit ambiguous to me, not sure if it happens automatically, or if it's only triggered (i.e. returning everything back to normal/as it was before, again) IF trim enabling is switched off again??
Don't know enough about any of the above to know if this is something worth risking/worrying about?

But does the kext signing remain deactivated all along, until you switch off TRIM, or is it reactivated the 2nd time? I'm not entirely sure what kext signing is, but this part has me a bit concerned:
"To continue to use Trim Enabler and continue to get Trim for your third party SSD, you first need to disable the kext signing security setting... It is important to note that the kext-signing setting is global, if you disable it you should be careful to only install system drivers from sources that you trust."
But presumably TRIM is important? So should I stop whingeing and just do it? :wtf:

Installing 3.3 disables it for you. Kext signing is something new in Yosemite. I suspect it's a sort of "Windows Driver Signature" type thing for Mac OS. Haven't delved too much into it, but I don't see it being a big deal if I apply Microsoft's logic to it with their digital driver signing.

Why go through the process where you restore from a time machine backup?
I mean it's not like a clean install since you're returning all your preferences etc.

I don't follow?
I restore all my apps and files.
How else will I get all my files and software back. Not going to download and re-install all the software again.

Why don't you just update your existing OS?
Ahhh...
Whenever there is a new major release be it OS X or iOS I always do a fresh delete and format and then a re-install. Just want to make sure all files are removed. And it never takes too long either.

Having done some snooping on other Mac forums - see quite a few unwilling to disable the kext signing... Apparently, a PRAM reset could result in a failure to boot if it's done. Many seem to reason they'd rather not enable TRIM than risk it...
Beginning to think the same...

No need to fear this; consider that Mavericks never had this feature so security risks are low.
As to problems with PRAM resets, hardware / software upgrades; just follow this advice: http://www.cindori.org/trim-enabler-and-yosemite/
easy-peasy
Extra note: I'd recommend you monitor the trim-enabler forum to avoid known issues; for example it appears activation with File Vault is an area for potential problems with Trim activation.

In all honesty, I don't see a problem with disabling kext signing and I've no idea why anyone else would moan about it either. This is the first iteration of OS X that has the feature, so prior to Yosemite it was a non issue, and for me it still is.

Exactly... plus it'll be the only option for the hackintosh guys, which should provide some comfort that there'll be quite a bit of interest to find maintainable / reliable worlarounds.
Side note:
Prior to the current kext signing, Apple's security essentially relied solely on keeping AHCI driver specs private (not good); this alignment (signing) brings this aspect inline with the rest of OSX, and ultimately one could posit that Apple could now legitimately allow registered developers the ability to build their own AHCI drivers without limited or at least controllable risks.
Off topic but.. is this app worth it? 1st time i hear of it so curious. and at what usage on SSD i.e. volume % used does it become worthwhile having it.. i mean if my disk is >75% (which happens as everything is in the cloud or my own server, plus its still new )
)

Short answer, yes, it's worth it. Mac OS tells the SSD when to clean up blocks, which helps with the slow down of SSDs over time. That's more or less the idea behind TRIM. Overall, it increases performance of the SSD. The free version is all you need, so you've got nothing to lose by trying it
