Overview

A bit more than six months after bumping the fastest TiBook from 667 MHz to 800 MHz, Apple updated the titanium workhorse with faster processors (867 MHz and 1 GHz) and ATI Mobility Radeon 9000 graphics (with 32 MB of video memory on the slower model, 64 MB on the faster).

The 867 MHz TiBook has an 8x8x24x Combo drive that can burn CDs as well as read DVDs, and the 1 GHz model has a full-fledged SuperDrive that allows it to burn DVDs.

Closed Lid Mode: TiBooks support "lid closed" (or clamshell) mode, which leaves the built-in display off and dedicates all video RAM to an external display. To used closed lid mode, your 'Book must be plugged into the AC adapter and connected to an external display and a USB mouse and keyboard (you might also want to consider external speakers). Power up your 'Book until the desktop appears on the external display and then close the lid. Your 'Book will go to sleep, but you can wake it by moving the mouse or using the keyboard. The built-in display will remain off, and the external monitor will become your only display. Since all video RAM is now dedicated to the external monitor, you may have more colors available at higher resolutions. The TiBook is designed to run safely in closed lid mode, but if yours runs hot (perhaps due to overclocking or high ambient temperatures), you may want to open the lid when in closed lid mode: The screen will remain off and the computer will more readily vent heat from the CPU.

To resume use of the internal display, you need to disconnect the external display, put the computer to sleep, and then open the lid. This will wake up your 'Book and restore use of the built-in display.

Why you should partition your Mac's hard drive, Dan Knight, Mac Musings, 2008.12.11.

Cautions

Do not under any circumstances use the Password Security control panel with any PowerBook running Mac OS 9 - see PowerBook (FireWire): Late Breaking News - it will render your PowerBook inoperable. The only fix is to put the drive in an older PowerBook, open Password Security, go to Setup, and click the Reset button, and then put the drive back in your 'Book.
There is an incompatibility between the Kensington Startup ADB extension and the Trackpad control on the iBook with Mac OS 9.0.4. Symptom: trackpad responds during boot, but not later. Solution: disable Kensington Startup ADB extension. This may also apply to other USB portables and versions of the Mac OS.
