iMac: How to Upgrade the Internal Drive

Many users have chosen the iMac, but there have been obstacles to upgrading the internal drive, the main one being the need for custom thermal regulation, a problem which OWC has solved with their upgrade kit.

OWC has do-it-yourself videos and toolkits, or the iMac can be upgraded by a professional installer.

Unlike Prior Generations, Apple iMacs from late 2009 to current 2014 & 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 6.0TB.

MPG suggests the HGST 6.0 TB Deskstar NAS drive for such an upgrade, but there are many other HDD choices.

SSD addition

With certain models, an SSD can be added to the hard drive for dual internal drive operation (hard drive + SSD), which enables Apple’s 'Fusion' technology.

Add an OWC Solid State Drive (sold separately) to your hard drive only equipped iMac to experience faster booting, near instant application launches and data transfer speeds up to 559MB/s!
