How to replace a 3.5″ Hard drive in a 2012 – 2019 iMac 27″

Replacing the hard drive (or upgrading to an SSD) in a 27-inch iMac from 2012 to 2019 is a moderately difficult task that involves carefully separating the display from the chassis (which uses strong adhesive strips), disconnecting cables, and accessing internal components. Apple does not officially support user-replaceable storage for these models beyond RAM on the 27-inch variants, so this is a third-party/DIY procedure.

The process is largely similar across Late 2012 through 2019 models (both non-Retina and Retina 5K versions), with minor variations in adhesive handling or bracket sizes depending on the exact year/EMC number.

Clone your old OSX to a new SSD

Most Apple Engineer have most probably got several USB Ext hard drives they use as a clean boot system (operating system) for testing purposes. With that in mind creating the drives is somewhat time consuming and to replicate the drive setup from scratch can encounter glitches. If you have a bootable drive and require either a copy or a hardware upgrade of the USB drive your best option would be to look at cloning the drive to a new USB ext drive. We are going to look at anything from Catalina and before within this article.
