Help Needed Swapping HDD for SSD
Here you go

I used something similar for my HD, then booted from it. Once I knew it booted ok, I swapped it with the old drive and bam..... Like nothing ever changed. This was 2 months after I purchased my MBP late 2011 model in March of 2012. Never had a single prob. Still runs great to this day.
And yes, it is a bare interface. Perfect to have if needed for an emergency.

So what exactly is TRIM support? And do I need this? Someone mentioned that resetting PRAM if TRIM is enabled would cause problems. Is this true for all situations? It would be a real pain to have to remember to turn it off before doing a reset. Not that i reset PRAM alot, but I don't know if I would remember. I read somewhere that you can leave it turned off and wont be a big deal. Your thoughts?
TRIM will boost performance, and even then, the performance boost would probably not be that noticeable in the routine of an average user.
It's not required ...
Especially with the advent of kext signing in OS X 10.10, as that just makes the whole scenario crappy for the average user. Forget one time to disable TRIM prior to installing an OS X update, and that average user will find themselves down the proverbial rabbit hole, of which it would be a bit of an adventure to get themselves out.
FWIW, resetting PRAM has no affect on TRIM. If somebody ran into troubles resetting PRAM and they had TRIM enabled, the two were most likely unrelated, and any alleged relationship between them was most likely pure speculation or assumption.

- You won't have any issues. Just don't do SMC or NVRAM resets without disabling it. Even if you do inadvertently do it, it's quite fixable.
I've used TRIM on mine for more than 2.5 years without close to an issue.

Using TRIM won't cause issues itself. Forgetting to disable it prior to updating OS X 10.10 will cause issues, but that's not a problem with the TRIM feature itself. It's just the cost of doing business in a kext-signed world.
If you feel you don't want to be bothered to remember turning off TRIM support before doing any OS X updates, then don't bother enabling TRIM. You won't lose out in any significant way by not bothering with it.
- Nonsense. Updating OS X causes no issues at all with TRIM. It simply disables it, after which you can just enable it again and be on your way.
The handy piece of software that is TRIM Enabler will even remind you to enable TRIM any time it is disabled.
Well done. Have you actually any personal experience with this?
I have been running with TRIM for 2.5 years, have installed every OS X update as it became available, never once disabled TRIM before it and have had zero issues.
Ergo, it doesn't cause any issues to update OS X with TRIM enabled.
Do you have experience with TRIM under Yosemite? It's absolute hell. Doing an PRAM reset or updating the computer 9 times out of 10 will re-enable Kext Signing. This is only under Yosemite. There is no way to permanently disable Kext signing and if you forget to turn it off your computer will reboot to a prohibited sign. You end up having to boot into Recovery, run a handful of Temrinal commands, then reboot the system. You have to disable TRIM then reboot before you install the update.
One time those commands didn't even work for me since the spare copy of the official Apple-signed Kext was not backed up by the TRIM Enabler app so I just ended up having to restore via Time Machine. Spent the whole day doing that **** so when I got back into OS X I didn't even bother re-enabling it. It's not even Cindori's fault, it's Apple's for the damn Kext Signing. If there was a way to permantently disable it I would. The only option is to get an SSD that officially supports Apple TRIM or TRIM at the hardware level.
Again, Kext Signing is under OS X Yosemite only. Mavericks didn't have it and Apple bills it as a security feature. Yeah sure.
- Yes. Runs perfectly.
As I said, I've installed every OS X update. And as I said above, updating OS X (from Yosemite onwards) will indeed disable TRIM, since it will re-enable kext signing. But it won't cause any issues as such (at least in my experience). One can simply enable TRIM again and then that's that.
The only thing to look out for is SMC and NVRAM resets.
Are you saying you have experienced problems when updating OS X while TRIM was enabled (other than it simply enabling kext signing and therefore disabling TRIM)?
Yes, if I update OS X it re-enables kext signing causing every machine I have used TRIM Enabler on (from MBPs to oMPs) to boot up to this sign:
I end up having to boot into Recovery and run these commands via Terminal before I can get back up and running.
It doesn't always happen, but I would say 9 times out of 10 a major update comes out and changes the build number (Security Update, 10.10.x update, etc) that happens. As soon as I see slowing I'll reinstall OS X (probably about a year) which should clear all that out.
- In that case I must apologize for appearing too sure of myself in my above comments. I had assumed my experiences were indicative of simply the way this kext signing business works with updates, and not of local variables, and that therefore others would see the same.
It appears that isn't the case then. I'll keep that in mind when giving advice going forward.
Thanks.
Perhaps I'm just lucky with my configuration...
- Just updated to 10.10.3 without disabling TRIM beforehand - not a single hitch. The worst issue was this (fully expected) message after the update.
It's curious, really, that I'm seeing no issues at all when you and others apparently have big problems...

Best guess would be luck. I wish it worked like that on my system. Re-enabling it isn't a big deal, but Yosemite will just refuse to boot with the Kext in place on both my systems and family member's systems.
Just wanted to come back to say thanks for all the help. I just completed the SSD and Eam swap, and The upgrade couldn't have gone smoother. The boot to time machine recovery partition worked like a charm. I thought it would first make me install tge OS and then restore from the time machine backup, but as soon as I got booted and formatted the new SSD, it went straight to letting me restore. Took about 90 minutes, but worked great. Now my wife's 2011 MBP boots up in 7 seconds (even faster than my brand new 2015 rMPB by about 5 seconds). She hasn't tested it yet with her Adobe apps (CS6 and CC) but based on the super fast boot time and the quick launching and shutdown of her apps, I think this SSD and upping from 4GB to 16GB of ram is going to be a huge improvement. Very happy.
Thanks again all!
Thanks again all!
