HDD Upgrade/Replacement Kits for iMac

Complete HDD Upgrade Kits for Apple iMac 2009 – 2017. Install up to a 10TB Hard Drive.

Thanks to OWC's innovative drive upgrade kit, you can add up to a 10TB to your iMac. OWC's iMac Drive Upgrade Kit is the only solution on the market to offer full compatibility with the digital thermal reporting in Apple's SMC.

Unlike Prior Generations, Apple iMacs from late 2009 to current 2015 & later utilize digital reporting and even custom firmware for SMC drive temperature reporting. OWC's Exclusive HDD Kits include our custom digital monitor that 'talks Apple SMC' and maintains proper temperature reporting and Apple Diagnostic compatibility allowing you to upgrade an existing 3.5" HDD with any 3.5" SATA HDD of your choice up to 10TB.

Each Upgrade Kit is designed specifically for iMac, requires no software hacks and ensures compatibility with Apple's built-in diagnostic processes. Without the OWC in-line thermal sensor, included in the kit, your system can't accurately manage cooling, and the fan will run all the time. With the sensor, your new drive works with the SMC, just like a factory installation.
