Imac Early 2009 Os Upgrade

The exceptions are the early 2006 models with the iMac 4,1 or iMac 4,2 identifier. These models used the Intel Core Duo processors, the first generation of the Core Duo line. The Core Duo processors use a 32-bit architecture instead of the 64-bit architecture seen in later Intel processors. 24' Original/Mid-2007 through Early 2009 iMac Hard Drive Upgrade Video From watching the videos, it should be clear that upgrading the hard drive or SSD in these models is complicated. If you do not feel comfortable - or have the time - to perform the upgrade yourself, it always is a good idea to hire a professional. Aimed at consumers and professionals alike, Mac OS X aimed to combine the stability, reliability, and security of Unix with the ease of use afforded by an overhauled user interface.

How do you upgrade the hard drive in the 'Original/Mid-2007,' 'Early 2008,' 'Early 2009' and 'Mid-2009' (20-Inch and 24-Inch) Aluminum iMac models? What type of hard drive do they support? Can you swap the hard drive for an SSD?

Please note that this Q&A covers Aluminum iMac models with 20-Inch and 24-Inch displays. EveryMac.com also provides instructions to upgrade the hard drive and SSD storage in more recent 'Flat Edge' 21.5-Inch and 27-Inch aluminum models as well as the latest 'Tapered Edge' 21.5-Inch and 27-Inch aluminum line.

The 'Original/Mid-2007,' 'Early 2008,' 'Early 2009' and 'Mid-2009' Aluminum iMac models -- all Aluminum iMacs with a 20-Inch or 24-Inch display -- each have a 3 Gb/s SATA connector for a 3.5' hard drive and different models have a variety of different hard drives installed by default.

Apple considers the memory in these models to be a 'customer installable part' but the hard drive is not intended to be upgraded by end users. Upgrading the memory is extremely easy -- there is a small removable 'door' on the bottom of each system for this purpose -- but upgrading the hard drive requires one to remove the display and effectively disassemble the entire computer.

Disasembling the computer is not simple, but the hard drive in these models also can be swapped out with a faster 3 Gb/s SATA-equipped SSD, and the swap is no more difficult than upgrading the hard drive.

Identification Help

2009

All of the 20-Inch and 24-Inch Aluminum iMac models have the same hard drive support. However, specific upgrade instructions are a bit different -- particularly for 20-Inch models -- so it still is important to be able to identify your iMac precisely.

These models can be most readily identified in software by Model Identifier as well as externally via EMC number (located inconveniently under the 'foot' supporting the computer).

To locate the Model Identifier in software, select 'About This Mac' under the Apple Menu on your computer and click the 'More Info..' button. If the iMac is running OS X 10.7 'Lion' or later, you will need to click the 'System Report' button after clicking 'More Info..' as well. As always, EveryMac.com has carefully hand documented each EMC number and model identifier for your convenience.

These identifiers for each of the 20-Inch and 24-Inch iMac models follow:

iMac

Subfamily

EMC

Model ID

Mid-2007

EveryMac.com's Ultimate Mac Lookup feature -- as well as the EveryMac app -- also can uniquely identify these models by their Serial Number, which is listed on the underside of the foot along with the EMC number and within the operating system alongside the model identifier. More details about specific identifiers are provided in EveryMac.com's extensive Mac Identification section.

Hard Drive or SSD Upgrade Instructions

For adventurous -- and highly skilled -- users interested in replacing or upgrading the hard drive in 20-Inch or 24-Inch models themselves, site sponsor Other World Computing provides helpful step-by-step video instructions of the complex procedure:

20' Early 2009 and Mid-2009 iMac Hard Drive Upgrade Video


24' Original/Mid-2007 through Early 2009 iMac Hard Drive Upgrade Video


From watching the videos, it should be clear that upgrading the hard drive or SSD in these models is complicated. If you do not feel comfortable -- or have the time -- to perform the upgrade yourself, it always is a good idea to hire a professional.

iMac Storage Purchase & Professional Installation Options

Quality storage is important. Be sure to buy from a quality vendor that sells storage with a reputation for reliability.

In the US (and many other countries), site sponsor Other World Computing sells SSDs for all iMac models (as well as hard drives) for do-it-yourself upgrades.

In the UK and Ireland, site sponsor Flexx sells Aluminum iMac compatible SSDs and hard drives with free shipping. The company provides flat rate shipping to France, Germany, and Switzerland and inexpensive shipping for all of Europe, too.

In Australia, site sponsors Macfixit and Upgradeable sell iMac compatible hard drives and SSDs with fast shipping, a money-back guarantee and more.

The iMac 'Core 2 Duo' 2.66 24-Inch Aluminum (Early 2009) features a 2.66 GHz Intel 'Core 2 Duo' processor, with two independent processor 'cores' on a single silicon chip, a 6 MB shared level 2 cache, a 1066 MHz system bus, 4 GB of RAM (1066 MHz DDR3 SDRAM), a 640 GB (7200 RPM) hard drive, a vertically-mounted slot-loading DVD±R DL 'SuperDrive', NVIDIA GeForce 9400M graphics with 256 MB of memory shared with the system, a built-in iSight video camera, and built-in stereo speakers underneath the 24' glossy TFT Active Matrix LCD (1920x1200 native) display.
Connectivity includes four USB 2.0 ports, a Firewire '800' port, built-in AirPort Extreme, and Gigabit Ethernet, as well as a Mini DisplayPort, which supports an external display in 'extended desktop' mode.
The iMac 'Core 2 Duo' (Early 2009) models are quite similar to the 'Early 2008' models that they replaced, with similar external cases -- varying only by a 'tapered foot' -- and likewise have the same glass cover that 'joins precisely to the aluminum enclosure creating a virtually seamless front surface'.
Although clockspeeds and configurations are similar as well, there are a few differences -- the Firewire '400' port on the Early 2008 models has been swapped for an additional USB 2.0 port on the Early 2009 models, Mini-DVI has been swapped for Mini DisplayPort, and the 2009 models also have DDR3 memory (rather than DDR2) with twice the official capacity, improved graphics on the higher-end configurations, and by default, shipped with a smaller keyboard that lacks the numerical keypad.
