Only Macintel models can boot from GPT hard drives. Intel-based Macs use a partitioning scheme known as GPT. If a second high-powered device is attached, it will behave like a normal bus-powered hub and only provide 100 mA per downstream port. Unlike earlier iMacs, where every USB port could provide 500 mA of power, only a single high-powered device can be attached to the USB ports, and software will enable one of its downstream ports to supply 500 mA of power. This should be good enough for most users. Note that 20″ aluminum iMacs use an 18-bit LCD, which can only display 262,144 colors, not the “millions” all other iMacs can display.

Upgrades as high as 2.8 GHz are possible (see CPU Upgrade Options for Mid 2007 iMacs). The CPU is in Socket P and uses an 800 MHz FSB (front side bus). More RAM always makes OS X run more smoothly. OS X 10.8 Mountain Lion and 10.9 Mavericks really call for 4 GB, and 10.10 Yosemite and 10.11 El Capitan want the 6 GB maximum Mid 2007 iMacs support – even though Apple says Yosemite will run with 2 GB. For OS X 10.7 Lion, 2 GB is a starting point and 4 GB will make you happier. While 1 GB of system memory is plenty to run OS X 10.4 Tiger comfortably, it is just adequate for OS X 10.5 Leopard and truly inadequate for OS X 10.6 Snow Leopard, which isn’t happy with less than 2 GB. See our macOS Sierra page for more details and a link. Even then, WiFi is not supported on this device.

There are also many complaints about reflections due to the glossy display.Īlthough it is not officially supported, the Mid 2007 iMac can run macOS Sierra using Colin Mistr’s Sierra Patch Tool if you replace its Merom CPU with a Penryn CPU. Gaming benchmarks measure GeForce frame rates as anywhere from 20% to nearly 200% higher. The Radeon HD 24 Pro graphics processors, while better than the Radeon X1600 GPU in the previous generation 2.0 GHz iMacs in some respects (and worse in others) is a step down from the Nvidia GeForce 7300GT and 7600GT in the earlier 24″ iMac.
This is the oldest iMac that supports OS X 10.8 Mountain Lion and later ( OS X 10.9 Mavericks and later are free, and OS X 10.11 El Capitan is the last version supported).

The new iMac ships with Mac OS X 10.4.10 Tiger and iLife ’08. The 2.4 GHz models ship with a 320 GB hard drive and use Radeon HD 2600 Pro graphics. The 20″ 2.0 GHz iMac ships with 1 GB of RAM, a 250 GB hard drive, an 8x SuperDrive, Radeon HD 2400 XT graphics, AirPort Extreme, Bluetooth 2.0, and Apple’s new keyboard and Mighty Mouse.
They have three USB 2.0 ports, FireWire 400 and 800 ports, gigabit ethernet, 802.11n WiFi, and an upgraded SuperDrive – as well as a brand new slim aluminum keyboard with USB 2.0 ports. Three models use a Core 2 Duo Merom CPU (a 24″ 2.8 GHz Core 2 Extreme model was available as a build-to-order option) with the same Santa Rosa chipset and 800 MHz bus found in the Mid 2007 MacBook Pro models. Unlike the Late 2006 iMac, there is no longer a 17″ model – only 20″ and 24″ models. The new aluminum iMac is thinner than the old one.
