iMac (Late 2006)

White flat panel iMacIndustry watchers have been anticipating this: Apple moved the iMac to Intel’s Core 2 Duo processor, which is up to 50% more powerful than the Core Duo used in the Early 2006 iMac. As if that wasn’t enough, Apple has added the biggest iMac ever to the line, a whopping 24″ model with a 1920 x 1200 pixel display.

All four models (17″ 1.83 and 2.0 GHz, 20″ and 24″ 2.16 GHz) use a 667 MHz bus, have 3 USB 2.0 ports along with at least one FireWire 400 port, gigabit ethernet, and AirPort Extreme.

There’s more variety than ever before in the iMac line. The entry-level model uses Intel GMA 950 graphics, carried over from the education iMac introduced in July. This model comes with a Combo drive, 512 MB of RAM, a 160 GB hard drive, 2 FireWire 400 ports, and Apple’s USB keyboard and Mighty Mouse. Because this model dedicates 64-80 MB of RAM for video, we strongly recommend at least 1 GB of RAM in this model.

The 2.0 GHz 17″ iMac has 1 GB of RAM and a 160 GB hard drive, an 8x SuperDrive, AirPort Extreme, Bluetooth 2.0, and Apple’s USB keyboard and Mighty Mouse.

The 20″ and 24″ models ship with a 250 GB hard drive.

The 17″ 2.0 GHz and 20″ 2.16 GHz models use the ATI Radeon X1600 graphics processor with 128 MB of memory, while the 24″ iMac includes Nvidia GeForce 7300GT graphics with 128 MB of video RAM. The 24″ model is the only iMac to include FireWire 800.

The new iMac ships with Mac OS X 10.4.7 and iLife ’06.

Intel-based Macs use a partitioning scheme known as GPT. Only Macintel models can boot from GPT hard drives. Both PowerPC and Intel Macs can boot from APM (Apple’s old partitioning scheme) hard drives, which is the format you must use to create a universal boot drive in Leopard. PowerPC Macs running any version of the Mac OS prior to 10.4.2 cannot mount GPT volumes. PowerPC Macs won’t let you install OS X to a USB drive or choose it as your startup volume, although there is a work around for that.
