iFixit sells a great roller (see above) for spudging the display off that eases the job considerably. Use a large workspace, and remove move anything hard or pointed that you could conceivably bang into and break the glass. One thing I will say is to be careful removing the display and handle it with care. FccZoneĪ spudging wheel such as this is worth its weight in gold when it comes to removing the display from an iMac. The procedure is hardly difficult, but it requires patience, a modicum of finesse, and some tools. Frankly, I can’t do better than the easy-to-follow and granular guide on, which is what I used the first time. I won’t bore you with the complete tear-down instructions for a 2015 iMac. The company armed me with a number of relevant tips, and sent me a 512GB M13 Feather SSD kit with macOS High Sierra pre-installed. Finally, I stumbled on a company with an office in Birmingham, Alabama called Fledging, whose Feather drives run around 25 cents per gigabyte and are available in up to 2TB of capacity. That’s better, but they were from unfamiliar companies I was unable to chat with. Perusing further, I found Apple-compatible SSDs for around 30 cents per gigabyte. OWC’s compatible drives on Newegg were 40 cents per gigabyte, and Apple’s on Amazon were an incredible $1 a gigabyte! This is 2019: standard M.2 2280 NVMe SSDs start at 15 cents per gigabyte! A huge issue is that Apple uses proprietary connectors. Finding a NVMe SSD for the upgradeĪs I intimated, there was never any question that the NVMe SSD could be upgraded, just whether it could be done for a reasonable price.

With the disclaimers out of the way, here’s how you can upgrade an iMac’s NVMe SSD with something cheaper, faster, and more capacious. If you’re careful, you shouldn’t, but stuff happens.

You also run the risk of permanently damaging your iMac. If your iMac shipped with a Fusion Drive or SSD, read on.Īnother disclaimer: if your iMac is still under warranty, this will void it.

But there is a viable option you can read about- NVMe via Thunderbolt. Authoritatively stated advice such as “You’ll kill the machine and possibly yourself” was hardly useful (not to mention, completely incorrect), while “Well, it worked in my 2017 ” provided hope, but no specifics.Īfter buying the iMac (it was a bargain I had to jump on) and later talking with vendors, it became apparent that my leap of faith (and general storage knowledge) had been justified.Ī disclaimer: if you bought a 21-inch iMac with a standard hard drive, you’re out of luck-these iMacs didn’t have an PCIe SSD slot on the board. I found conflicting info about the upgrade, though.

I wanted to upgrade the iMac’s NVMe SSD with something that offered more space but was relatively less expensive (in other words, not sold by Apple). I bought it with upgrading in mind, which is where the fickle finger of fate came into play. So much so that I took a chance and bought a used 2015 low-end Core i5 iMac with a 1TB Fusion Drive (which combines a 24GB NVMe SSD and a 1TB hard drive)-a machine that’s actually slower than my 2012 Core i7 iMac.
