Apple iMac 24-Inch 'Core 2 Duo' 2.66 (Early 2009) Specs
IMac is a family of all-in-one Macintosh desktop computers designed and built by Apple Inc. It has been the primary part of Apple's consumer desktop offerings since its debut in August 1998, and has evolved through seven distinct forms. 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'.

Having a Metal GPU makes your iMac Late 2009, Mid 2010, Mid 2011 Big Sur compatible. To make the package perfect and nearly fully compatible you could have installed an WiFi/BT upgrade, but it is not necessary to install and run Big Sur. The stock old Atheros WiFi card will be supported. MacBook Air (early-2008 release onwards), Mac Pro (early-2008 release onwards), Mac Mini (Early-2009 onwards), Xserve (Early-2009), MacBook (Early-2015) Cost is an important factor when trying to upgrade from a previous to higher version. The Intel-based iMac is a series of Macintosh desktop computers designed, manufactured and sold by Apple Inc. It is a member of the iMac family. It is one of four desktop computers in the current Macintosh lineup, serving as an all-in-one alternative to the Mac Mini, and sits below the performance range iMac Pro and Mac Pro.

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.
