MacBook2,1 and MacBook1,1


Return to index

There is an Apple laptop called the macbook1,1 from 2006 which uses the same i945 chipset as the ThinkPad X60/T60. A developer (Mono Moosbart) ported the Macbook2,1 to coreboot, working alongside Vladimir Serbinenko. The ROM images also work on the macbook1,1. Libreboot’s support and documentation for this is based on the Libreboot project, which also supports macbook2,1

Some macbook2,1 models are late 2006, others are early 2007. You do not need to use external flashing equipment when flashing the MacBook2,1 but the MacBook1,1 requires external flashing equipment while running Apple EFI firmware.

Macbook2,1 laptops come with Core 2 Duo processors which support 64-bit operating systems (and 32-bit). The MacBook1,1 uses Core Duo processors (supports 32-bit OS but not 64-bit), and it is believed that this is the only difference.

Compatibility

The following pages list many models of MacBook1,1 and MacBook2,1:

Internal flashing

Macbook2,1 can always be flashed internally, even if running Apple firmware:

sudo flashrom -p internal:laptop=force_I_want_a_brick,boardmismatch=force -w your.rom

Macbook1,1 same as above, but if running Apple firmware see below for external flashing.

External flashing

macbook1,1 requires external flashing, if running the default Apple firmware. macbook2,1 can be flased internally, regardless. If running coreboot, libreboot or Libreboot, you can already internally re-flash.

Locate the flash. It’ll be a SOIC8, which looks like this:

Refer to the following guide:
Externally rewrite 25xx NOR flash via SPI protocol

You need to replace OS X with GNU+Linux before flashing Libreboot. (OSX won’t run at all in Libreboot), if you wish to internally flash on a macbook21. Libreboot won’t boot OSX either (well, maybe with Tianocore it would, but that’s untested and OSX is inferior to GNU+Linux). In general you should think of your Macbook like a regular laptop, for the purposes of anything coreboot.

If it’s a macbook2,1 with the core2duo processors, you can run a 64-bit distro. For macbook 1,1 the CPU probably only has 32-bit support.

GNU+Linux on Apple EFI firmware

How to boot an ISO: burn it to a CD (like you would normally) and hold down the Alt/Control key while booting. The bootloader will detect the GNU+Linux CD as ‘Windows’ (because Apple doesn’t think GNU+Linux exists). Install it like you normally would. When you boot up again, hold Alt/Control once more. The installation (on the HDD) will once again be seen as ‘Windows’. (it’s not actually Windows, but Apple likes to think that Apple and Microsoft are all that exist.)

The following page has some information:

Issues and solutions/workarounds

There is one mouse button only, however multiple finger tapping works. Battery life is poor compared to X60/T60. The Apple logo on the back is a hole, exposing the backlight, which means that it glows. You should cover it up.

The MacBook2,1 comes with a webcam which does not work with free software. Webcams are a privacy and security risk; cover it up! Or remove it.

Enable AltGr

The keyboard has a keypad enter instead of an AltGr. The first key on the right side of the spacebar is the Apple “command” key. On its right is the keypad enter. We can make it act as an AltGr.

If your operating system is Trisquel or other dpkg-based distribution, there is an easy solution. Under root (or sudo) run

dpkg-reconfigure keyboard-configuration

and select the option “apple laptop”, leave other settings as their defaults until you are given the option “Use Keypad Enter as AltGr”. Select this. The keypad enter key will then act as an AltGr everywhere.

For Parabola or other systemd-based distributions you can enable AltGr manually. Simply add the line

KEYMAP_TOGGLE=lv3:enter_switch

to the file /etc/vconsole.conf and then restart the computer.

Enable 3-finger tap

A user submitted a utility to enable 3-finger tap on this laptop. It’s available at resources/utils/macbook21-three-finger-tap in the Libreboot git repository.

Make touchpad more responsive

Linux kernels of version 3.15 or lower might make the touchpad extremely sluggish. A user reported that they could get better response from the touchpad with the following in their xorg.conf:

Section "InputClass"
 Identifier "Synaptics Touchpad"
 Driver "synaptics"
 MatchIsTouchpad "on"
 MatchDevicePath "/dev/input/event*"
 Driver "synaptics"
The next two values determine how much pressure one needs
for tapping, moving the cursor and other events.
 Option "FingerLow" "10"
 Option "FingerHigh" "15"
Do not emulate mouse buttons in the touchpad corners.
 Option "RTCornerButton" "0"
 Option "RBCornerButton" "0"
 Option "LTCornerButton" "0"
 Option "LBCornerButton" "0"
One finger tap = left-click
 Option "TapButton1" "1"
Two fingers tap = right-click
 Option "TapButton2" "3"
Three fingers tap = middle-mouse
 Option "TapButton3" "2"
Try to not count the palm of the hand landing on the touchpad
as a tap. Not sure if helps.
 Option "PalmDetect" "1"
The following modifies how long and how fast scrolling continues
after lifting the finger when scrolling
 Option "CoastingSpeed" "20"
 Option "CoastingFriction" "200"
Smaller number means that the finger has to travel less distance
for it to count as cursor movement. Larger number prevents cursor
shaking.
 Option "HorizHysteresis" "10"
 Option "VertHysteresis" "10"
Prevent two-finger scrolling. Very jerky movement
 Option "HorizTwoFingerScroll" "0"
 Option "VertTwoFingerScroll" "0"
Use edge scrolling
 Option "HorizEdgeScroll" "1"
 Option "VertEdgeScroll" "1"
