Post subject:  SSD upgrade on late 2012 iMac 27"

My iMac seems to be getting a bit slow and would like to know if its an easy job to upgrade it to a 1TB SSD, or would I benefit from keeping the original HD and having it configured to a fusion drive with the 1TB SSD and HD which is also 1TB.

If its a complicated job any recommendations in the Manchester area for Apple certified repairs. Have looked at Crucial SSD's and a 1TB SSD is about £265 so with any extra's and fitting Im looking to spend if its a difficult job for me (as in removing the screen) about £450 ish.

I would like a new iMac but not possible at the moment.

On that model of iMac, unless you’re confident removing the glass and display, I would suggest asking an expert!

If looking for someone local in Manchester, I could recommend CS Systems in Old Trafford, they’re Apple Authorised Repairers so know what they’re doing. We use them at my current job for all our I.T. Support and I used them in my previous job for over 15 years.

If they ask, tell them Steve Harrington recommended them to you...
CS Systems: 0161 872 0921
Email: enquiries@cssystems.net
Ask for either Adrian or Barbara

Or, if you’re happy to send it further afield (appreciate not everyone is), there’s always our Darren:

Make sure you also have a backup before taking it in or sending it away.

For that budget, could I suggest a 500GB SSD? I just created a fusion drive (with Dave's help :D ) from a 1 TB HD and 128 GB SSD, and it makes a YUGE difference over my previous Mac, and I'm sure the difference between i5 and i7 doesn't account for more than a fraction of the improvement.

Darren is not a problem but the distance in between is I would not like to trust whoever the carrier is to get it to him safely and back.

Yes the screen was my real concern as a DIY job, as stated the earlier ones had clips a lot easier to remove. I watched a video of a screen removal with the tape and its not for the faint hearted.

But I will get in touch with CS Systems.
Cheers Steve.

Well Steve got in touch and Adrian answered my email. Very please with the price quote (and a Steve Harrington discount to boot thanks). I re-emailed him last thing tonight to clarify if I need a thermal heat sensor fitting. As Apple don’t allow third party hard drive access to the sensor, have read that you have to buy an adapter.

Thanks again for the heads up.

Great, they’ll be able to sort the upgrade out for you, they’re a friendly bunch, even better if they gave you a discount!

One last query, I have read that I cannot use the thermal heat sensor from the old HD and need to purchase an external self adhesive one. It's to stop the system from thinking it needs more cooling and spinning the fans is this right.

Have seen this one for £40 an OCW on Amazon https://www.amazon.co.uk/OWC-OWCDIDIMacHDD12-Digital-Thermal-27-Inch/dp/B00J42D5MK, is this what I'm after.

I don't want to take it in and find out I need this part would sooner have it and fitted to save time.

The guy that replied (Adrian) hasn't answered me on this question hence the query.

I don't know if it's required, it seems unlikely to me but I know Apple have done some weird things with these sensors. If the fitter just peels the sensor off the hard drive but does not disconnect electrically, it should be fine.

If you have a problem with the fans after installation you could fall back on Macs fan control software which I use now on my MBP, which is often a little on the warm side, even though I don't strictly need it. It allows me to control when the fans kick in, based on temperature of CPU, not on temperature of an SSD which will always be cool. I paid nothing for the software, the current version is free and it is easy to set up and use.

Just had an after thought will I need an adapter plate from 3.5 to 2.5 for this http://uk.crucial.com/gbr/en/imac-%2827-inch%2C-late-2012%29-imac13%2C2/CT8638250. If so can anybody point me in the right direction as I'm struggling to find an Apple compliant part so many and not sure which is which.

I've booked it in for the upgrade on Monday so needs sorting rather fast please guys.

Any should do the trick - moving from 2.5" to a 3.5" is a standard fitting.

I used the ICY unit. Fitted perfectly in the bay with a Crucial SSD.

Thank you all for you input. Hopefully all should go as planned now.

And James you know Apple don't normally do standard hence my question.

They do use many standard parts, (but sometimes use proprietary parts too) - like some of their card SSDs for example - although this is a standard piece of equipment; a 3½ inch hard drive to be replaced by a 2½" SSD is a straightforward task. The mounting holes are of standard size and location for these devices.

I'm sure you'll be very pleased with the results - You'll have a whizzy Mac afterwards!

Herodotus, is this your iMac?

If so it appears to have two fast SATA III 6Gb/s logic board hard drive connections and I presume that the second one is currently not used for anything. In which case why don't you add a small SSD - say 120 GB - to the spare connection? Then you can make a Fusion drive. It will be much less costly, you will end up with a 1.12 TB Fusion drive for around £200 less and the Fusion drive's performance is pretty close to that of an SSD. You could delay the upgrade for a few days and save some dosh.

Just change your SSD order + you will need an extra cable to connect to the second drive, available online. You wouldn't need to buy a mechanical mount for the SSD, they are so light all you need is four double sided sticky pads to stick it to the inside of the case. There are how-to's on the iFixit website.

Although this is illustrated for a different model, if yours has two hard drive bays it should be fairly similar.
