Easily add an SSD to ANY iMac 2012-2019 model

With it's all in one design, iMacs are a pain to upgrade, you can't even upgrade the ram easily on the 21.5" model and until the new 2020 models, most of them shipped with slow spinning hard drives that only get slower over time. In this How to video I show you how I super easily added an SSD to my Family Computer 2012 iMac which had a startup time of 3 minutes!

Thank you so very, very much. My husband would have a fit every time he tried to work on our iMac...to pay a bill or check something, etc. Ugh. It was so very frustrating. You literally saved us so much time, money, and headaches! Installed the new SSD external drive and followed your directions. What a changed world it is to use that machine now! Oh, my.

THANK YOU for the fantastic tutorial and explanation to understand why so many iMacs have a problem with speed. I’ve been suffering with my annoyingly slow iMac desktop for the 3 years-ever since I bought it-and even tried to get professional help.

[@timallix4407]

Great idea if you don't want to open the computer, which is very tricky and requires patience and a steady hand. You can save some time by going into recovery mode (Option R), then perform a "restore" to the USB drive. This will "clone" the old HD to the new one, saving you the time of backing up, and then re-loading a fresh copy of the OS (which is actually unnecessary). Then you can use the option key to set the default boot device to the newly cloned external HD. I've just been through this, and it works. I went one step further: I removed the screen and properly installed the newly cloned SSD drive inside the enclosure. A word to the wise if you attempt this: don't use a metal knife to cut the glue on the monitor, I have wrecked two monitors in my experimentation. Use a plastic bladed "pizza cutter" to cut the glue strips. You can buy this tool on Amazon, and it comes with the tape to glue the monitor back on. Cheers!

Hi Again. Looks like I celebrated a little too early :P My iMac (late Dec 2013) is stuck on the globe screen showing 0:01 as the remaining time... Been a couple hours.. Is it okay to force reboot the Mac or will it damage the OS on my hard drive? Please advise :)

[@garyfalosparisis9039]

Hello there! Thank you for this great video! I have one question, in terms of speed/performance is there a difference between using an external portable SSD vs opening the computer and installing an internal SSD? I would like to avoid the latter solution for a number of reasons. Moreover, my computer (late 2015 imac 27 retina) does not support PCI type internal SSD (only SATA-at least so I have been told) so my options are either an external USB 3.0 SSD or an internal SATA connection SSD. Thank you in advance!

[@ImLeeLoi]

I think there would be minor speed increases by using it internally but you can read the other comments down below a lot of people are very happy with their external SSD. Why go through all that effort!

[@garyfalosparisis9039]

@@ImLeeLoi thank you for your reply! actually I was planning to give it to a third party certified repair shop, they charge 270 euros in total for the work and SSD. I would never attempt to do something like that on my own! My biggest worry is of psychological nature I would say, running the whole computer from a tiny little stick hanging outside the computer feels a bit bizarre lol. However I may consider this option and if I am not happy I might as well keep the external SSD and go for the upgrade later on. Thanks again for your time!

Thank you so much for this video. My late 2015 was extremely slow for few years now. We completely wiped it out and the speed only improved by a little.

I am using San Disk Extreme Portable SSD 1tb.

I just used this method to upgrade my late 2015 imac 21.5" with a 1TB fusion drive; I added an external 1TB Samsung T7 SSD, for $99 ; it took me better part of a day -- I restored from a Timce Machine backup -- but also upgraded to Monterey from Big Sur. Took some tweaking but now it runs SO fast... take a couple of minutes to boot up (it is new software on an old machine) but once it's booted it is running incredibly fast.

Excellent video, thanks a lot. I did this a year ago with a SanDisk v1 that was formatted with APFS and it was a great improvement once it loaded the O/S - loading the O/S however took ages (+10 mins!!).

wow. great video. 2017 21.5in iMac that I thought was broken bc of how slow it was. I've contacted Apple numerous times to discuss how slow start up was and they finally recommended me to a local Mac repair company to upgrade the RAM and/or SSD. Thankfully I found your video bc I was quoted over $400 USD just to replace the HDD with an SSD. I will definitely try this first to see if it works for me. Thanks!

[@ImLeeLoi]

I can only recommend what I've used. I'm sure new drives came out. 400USD isn't actually that bad depending on how big the SSD is if it's like 1TB or something I'd probably pay that but yeah if it's like 240GB or something definitely go the external route. SanDisk or SanDisk Pro or Samsung are great bets. :)

@@ImLeeLoi Thank you. Will start with the external. The internal was 1TB but I'll start with the Samsung T7 to save more than half.

@@RogerZacharias Glad that's improved. Strange your boot time didn't get much faster, did you restore from backup or start fresh? If you restored from backup expect longer boot times as you carried over the system's past baggage which I've observed from some others who did this. If you did a fresh install, I'm genuinely confused why your boot time is long, I think some people who use the AFPS file format might be slower as that's for more internal drives than this method.

I did this to my 2015 iMac with a 1 TB Crucial SSD USB 3.0 external. It speeded it up VERY FAST!!

Thanks for this video. I noticed that the SSD you used, while inexpensive, had a much lower storage capacity that the original HD. Were you using the SSD only for system operations, and the original HD for regular document, email and/or image file storage, or did the SSD take over those functions as well? Thanks again for a well-thought, well-presented video.

Either or! Many in the comments are keeping their photos and videos on the old drive for infrequent access and most iMacs have 1TB which is a lot. It's the family computer so not much is stored on it in this situation.
