This is interesting news to Hackentosh and osx86 users, as the nForce kext included with the new Mac Books may yield better custom abilities.

The new MacBooks, MacBook Airs and MacBook Pros are here! The build number for the MacBook installs is 9F2114 which is using a (shock) NFORCE chipset, MCP79 AHCI Chipset using AppleAHCIPort.kext version 1.5.2, whereas our 9F33 10.5.5 version is using 1.5.1. It also has an IOAHCIFamily.kext and no IOATAFamily.kext
They’ve both received internal and external revamps which some hate and some love. They have a body made from one solid piece of aluminum which is promised to be thinner, lighter, and greener, with an LED backlit display. The more expensive MacBook option comes with a backlit keyboard, as do both of the new MacBook Pro offerings. The trackpads are made of glass on all the new notebooks.
They’ve all got brand new nVidia GeForce graphics cards, the MacBook and MacBook Air both have a nVidia GeForce 9400M with 256MB of shared DDR3 SDRAM, while the MacBook Pro has both a nVidia GeForce 9400M and a 9600M GT with options for either 256MB or 512MB of GDDR3 VRAM.
The “old” MacBook is still available (at a lower cost) with the integrated Intel GMA X3100 with 144MB of shared DDR2 SDRAM. The “old” MacBook Pro with the nVidia GeForce 8600M GT still has 512MB of GDDR3 VRAM.
The MacBook has options for 2.0GHz and 2.4GHz Intel Core 2 Duo. The “old” MacBook has a 2.1GHz Intel Core 2 Duo. The MacBook Air has 1.6GHz and 1.86GHz options. The MacBook Pro can come with either 2.4GHz or 2.53GHz, with the “old” MacBook Pro remaining at 2.5GHz.
2GB is the standard RAM on the new MacBooks, with the “old” MacBook remaining at 1GB standard. MacBook Air comes 2GB standard. 2GB is standard on the least expensive of the MacBook Pros, but 4GB is
standard on the higher-end MBP, as well as the “old” MBP.
All of the MacBook/MacBook Air offerings are 13.3-inch glossy. The new MacBook Pro is offered only at 15.5-inch glossy as well, no 17-inch or matte option there, the only matte (“anti-glare” or non-glossy) option, or 17-inch option for that matter, comes with the “old” MacBook Pro.
The new MacBooks come with options for 160GB, 250GB, 320GB (all 5400 rpm SATA) or a 128GB Solid State Drive (à la previous gen. MacBook Air). The “old” MacBooks come with options for 120GB, 160GB, or 250GB (all 5400 rpm SATA). The MacBook Air offers only two choices, a 120GB 4200 rpm SATA, or a 128GB Solid State Drive (which ups the price by $500 USD).
MacBook Pros have many more options, 250GB at either 5400 or 7200 rpm, 320GB at either 5400 or 7200 rpm, or 128GB Solid State Drive. The “old” MacBook Pro comes with 320GB at 5400 or 7200 rpm, or a 128GB Solid State Drive.
The “old” MacBook and the MacBook Air both come with a promised 4.5 hours of wireless productivity, while every other option (new MacBook, MacBook Pro, and the “old” MacBook Pro) all offer 5 hours of wireless productivity. This can most likely vary greatly, especially with the option for reducing the power consumption of the graphics card with a new power saving feature which must be restarted to work, offered by a new kernel extension “AppleGraphicsControl.kext” .
Gigabit ethernet (except on Air), airport extreme N, and iSight are all standard, for usb/firewire options the MacBooks only offer two usb 2.0 ports, the “old” MacBook has two usb 2.0 and one firewire 400. The Air
comes with one usb 2.0 port, the MacBook Pro comes with two usb 2.0 ports, one firewire 800, and one expresscard/34 slot, while the “old” MacBook Pro comes with three usb 2.0 ports, one firewire 400, one
firewire 800 and one expresscard/34 slot.
