How can I add a HDD for pure SSD iMac 27"? I have brought a iMac 27" 2015 Later with 512G SSD only. I want to add a 4T HDD to combine a 512G+4T fusion drive. How can I do it? Which kit should I buy?
Here’s the IFIXIT guide you’ll need to follow: iMac Intel 27" Retina 5K Display Hard Drive Replacement. You’ll need two cables this one: iMac Intel 27" 5K Late 2014 and Mid 2015 Hard Drive Cable as well as this one: OWC In-line Digital Thermal Sensor for Hard Drive Upgrade for 27" iMacs 2012 and Later. The bracket is present but you’ll need the T8 stud screws (4) Apple P/N 922-7001 HD screws. Be very careful removing the display! Its very easy to damage if you don’t follow the IFIXIT guide and use the correct tools.
