The iMac 'Core 2 Duo' 2.0 20-Inch (Aluminum) features a 2.0 GHz Intel 'Core 2 Duo' processor (T7300), with two independent processor 'cores' on a single silicon chip, a 4 MB shared level 2 cache, an 800 MHz system bus, 1 GB of RAM (667 MHz DDR2 SDRAM, PC2-5300), a 250 GB (7200 RPM) Serial ATA hard drive, a vertically-mounted slot-loading DVD+R DL 'SuperDrive', ATI Radeon HD 2400 XT graphics acceleration with 128 MB of GDDR3 memory, a built-in iSight video camera, and built-in stereo speakers underneath the 20' glossy TFT Active Matrix LCD (1680x1050 native) display designed to 'bounce sound off the desk below'.
Connectivity includes three USB 2.0 ports, a Firewire '400' port and a Firewire '800' port, built-in AirPort Extreme, and Gigabit Ethernet, as well as mini-DVI, which supports an external display in 'extended desktop' mode.
Externally, the 'Aluminum' iMac 'Core 2 Duo' models feature 'elegant' aluminum cases and have a glass cover that 'joins precisely to the aluminum enclosure creating a virtually seamless front surface' -- compared to white plastic cases used by the models these replaced. Additionally, the 'Aluminum' systems were paired with a 'new ultra-thin aluminum' Apple Keyboard (0.33 inches at the front edge) based on the polarizing keyboard design introduced with the MacBook.
Internally, some 'Aluminum Core 2 Duo' models have faster processors than their predecessors, but all have a faster 'Santa Rosa' motherboard design with an 800 MHz frontside bus (up from 667 MHz), additional RAM capacity, and both a Firewire '400' port and Firewire '800' port.

This tip replaces version 2126 originally released on the Discussions Feedback forum.

Find the serial number on:

Plug your serial number in at this link:

Do not use third party links as they may not be secure.

Do not post the serial number on this board, as that is your key to any support you may have left.

Use this tip also to help figure out which portion of the Support Community to post in, as this tip explains:

When you have no serial number, use one of these third party sites to find your model, production year, time in year

(early, middle, late, summer, fall, winter, spring):

Note:

PowerMac, PowerPC, eMac, iMac PPC, iBook (Apple recycled the name iBook for its eBook application on new Macs and iOS devices), Powerbook, Classic all refer to Macs that are older than the present series

of Macs. Posting in those forums about a current Mac, shows you have not researched your Mac sufficiently to get a succinct answer to your query. Apple menu -> About This Mac will tell you the Mac OS version or System version you are running. The X in the version is important, and so is the preceding 10 in the version if it exists.

Questions saying X.1 could refer to Mac OS X 10.13.1, 10.1. Don't truncate the version you see.

There are no iOS forums specific to the operating system found on iPads, iPod Touch, AppleTV, Apple Watch, and iPhones. Figure out the type of portable device you are running to ask a question about that device specifically.

Apple has these identifying articles as well:

Macs generally will not run an older Mac OS X operating system than shipped with them.

The one exception is virtualizing 10.6 Server on 10.7 or later, which is described later.

Also important to note is that the Apple App Store only has 10.7, 10.8, and 10.12, except for those who purchased in between systems, and have a Mac that shipped with in between systems. For all others if you need an in between system, and your Mac is older, contact the App Store tech support.

iMac (Late 2012 or newer) [13,1]
Mac Pro (Late 2013) [6,1]

These models above are the first models that can be upgraded directly to High Sierra 10.13 without other prior upgrades.

The oldest MacBook Air and iMac that can run Mac OS 10.14 after installing 10.11.

• MacBook Air 5,1

• iMac 12,1

These Macs which are older can also be upgraded to 10.12 by upgrading to 10.7.5 first, and 10.13 by upgrading to 10.8 first:

MacBook (Late 2009 or newer) 6,1
MacBook Pro (Mid 2010 or newer) 6,1

MacBook Pro Late 2008 [5,1] to Retina 2012 that are not EMC 2557.

July 20, 2011 will only run 10.7 or later. The model IDs (x,x) and EMC that fit this description until June 25, 2012 release of 10.8 (excluding the ones which will run only 10.8 or later earlier mentioned) :

Can A Mac Mini Be Upgraded

iMac of an EMC of 2496; 13,x and later.

Mac Mini 5,x and later.

Macbook Air 4,x and later.

MacBook 8,x and later (no Pro no Air in the name)

Mac Pro 5,1 with EMC 2629 - the oldest that can be have Mac OS 10.14 installed after installing 10.11 or later, those without that EMC number came with 10.6 and can also be updated to 10.14 the same manner; 6,x and later.

MacBook Pro with EMC 2555, 2563; 9,x and later.

Note all the Macs that can only run 10.7 and later, may be able to run 10.6 Server with Parallels, if you need compatibility with an older operating system:

Beyond this point Macs released during certain date ranges also have a maximum operating system, and/or

minimum retail operating system and system specific operating system requirement (when I say up to 10.9 that includes all incremental updates):

Note: images shown below for retail operating system are those that have no 'Update, Dropin, or OEM' wording on them.

March 15, 2010-July 19, 2011 will only run prebundled 10.6 installer disc, and not retail, but also able to be upgraded to 10.9. Note this tip

if upgrading to 10.7 or later: https://discussions.apple.com/docs/DOC-6271

August 28, 2009-March 14, 2010 will only 10.6 or later up to 10.9. And will at minimum be able to use

10.6.3 retailto install 10.6. Note this tip if upgrading to 10.7 or later: https://discussions.apple.com/docs/DOC-6271

During 2000 to 2009, the serial number also made it easier to identify the Macs, as the 3rd, 4th, and 5th character of the serial number referred to the week

and year of the shipment date. Thus for serial numbers where x can be any letter or number, xxABCxxxxx serial numbers would refer to an A which is the last digit of the year, and BC=week of the year. xx905xxxx is the fifth week of 2009. You can then use Wikipedia to figure out what date the release was, and if it was after a specific retail release of an operating system to determine which pre bundled disc it came with, and which later retail discs the Mac could work with.

December 15, 2008-August 28, 2009 will only run prebundled 10.5 installer disc, and 10.6 retail https://discussions.apple.com/content/attachment/43236040snow.jpg, and if on https://discussions.apple.com/docs/DOC-3761

January 10, 2006-October 27, 2007 will at minimum be able to 10.5 retail, and if

on Which 10.5 systems can upgrade to 10.8 or 10.9?or Are there 10.4 systems that can upgrade to 10.8 or 10.9? are

able to run 10.9. Core2Duo and Xeon can upgrade to a minimum of 10.7.5. Otherwise if they only have a CoreDuo, CoreSolo Intel

processor only be able to upgrade to Mac OS X 10.6.8. G5, G4, and G3 processors are not Intel.

Earlier dates are covered on this tip:Can I download my Mac OS upgrade?

Using the dates from the above documents, and the dates according to Wikipedia when specific retail

operating system systems were released, you can find which retail releases were newer than the Macs and the ones immediately older.

i.e.:

An October 24, 2011 Macbook Pro will only run 10.8 retail, and 10.9 retail downloads, but needs an

AppleCare requested 10.7 installer to install 10.7. An exception exists in 10.6 Server, as indicated here:

A pre-October 26, 2007 MacBook Pro will only run the system specific Mac OS X 10.4 installer

that shipped with it, which can be ordered from AppleCare, or newer retail installer versions

of 10.5, 10.6 compatible with its hardware, and 10.7 if it is at least a Core2Duo.

CoreDuo, nor is CoreSolo is not compatible with 10.7.

For PowerPC Macs, Mac OS X 10.4.11 and earlier offer Classic compatibility, and on certain 2003 and earlier Macs dual booting on Mac OS X 10.5 & Mac OS 9:

No Mac may run an older version of Mac OS 9 than was prebundled with it.
