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.īattery life is comparable to the 17″ PowerBook G4. Power PC Macs running any version of the Mac OS prior to 10.4.2 cannot mount GPT volumes. 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. Only Macintel models can boot from GPT hard drives. Intel-based Macs use a partitioning scheme known as GPT. This will wake up your ‘Book and restore use of the built-in display. To resume use of the internal display, you need to disconnect the external display, put the computer to sleep, and then open the lid. Since all video RAM is now dedicated to the external monitor, you may have more colors available at higher resolutions. The built-in display will remain off, and the external monitor will become your only display. Your ‘Book will go to sleep, but you can wake it by moving the mouse or using the keyboard. Power up your ‘Book until the desktop appears on the external display and then close the lid.
To used closed lid mode, your ‘Book must be plugged into the AC adapter and connected to an external display and a USB or Bluetooth mouse and keyboard (you might also want to consider external speakers). Note that the built-in display is only capable of 18-bit color, not the full 24-bit color you might expect.Ĭlosed Lid Mode: All Intel ‘Books support “lid closed” (or clamshell) mode, which leaves the built-in display off and dedicates all video RAM to an external display. This model shipped with Mac OS X 10.4.8 Tiger and supports OS X 10.7 Lion. It has 3 USB 2.0 ports, one more than the 15″ MBP offers. This model includes built-in dual-DVI support for Apple’s 30″ Cinema Display, ATI Mobility Radeon X1600 graphics, and an ExpressCard/34 slot (replacing the older PC Card). The other hardware improvement is use of an 8x SuperDrive with dual-layer burning instead of the 4x single-layer burner of the earlier 17″ MacBook Pro. Where the earlier model has a 120 GB hard drive, 160 GB is now standard, and there are two other options: a 100 GB 7200 rpm drive and a 200 GB 4200 rpm one. It now supports a maximum 3 GB of RAM, up from 2 GB on the earlier model. The new 17″ Core 2 model has a 2.33 GHz CPU and ships with 2 GB of RAM. Part of that comes from the more efficient CPU, and part from an 8% faster CPU. On 2006.10.24, Apple moved the MacBook Pro line to Intel’s newer Core 2 Duo CPU, claiming “up to 39% faster” performance than the model it replaced.
