title: MacBook2,1 and MacBook1,1
|
|
x-toc-enable: true
|
|
...
|
|
|
|
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.
|
|
|
|
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.
|
|

|
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 or libreboot you can already internally re-flash.
|
|
|
|
[This page shows disassembly
|
|
guides](https://www.ifixit.com/Device/MacBook_Core_2_Duo)
|
|
|
|
Locate the flash. It'll be a SOIC8, which looks like this:
|
|
|
|
|
|
|
|
motherboard. [How to remove the
|
|
motherboard](https://www.ifixit.com/Guide/MacBook+Core+2+Duo+PRAM+Battery+Replacement/529).
|
|
|
|
Refer to the following guide:\
|
|
[Externally rewrite 25xx NOR flash via SPI protocol](../install/spi.md)
|
|
|
|
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.)

|

|
Coreboot wiki page
|
|
==================
|
|

|
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](http://cweiske.de/tagebuch/tuxbook.htm).
|
|
The MacBook2,1 consumes more power with libreboot than with the Apple EFI firmware, which means it overheats a lot.
|
|
|
|
*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.*
|
|
|
|
Make it overheat less
|
|
---------------------
|
|
|
|
NOTE: on newer libreboot revisions, this section is less relevant, because C3
|
|
states are supported now. However, this section may still be useful, so it will
|
|
be retained.
|
|
|
|
The MacBook2,1 overheats a lot with libreboot, we still don't know why but a simple workaround is to install macfanctld.
|
|
|
|
Macfanctld is available on the default repos of many distributions.
|
|
|
|
For example, to install macfanctld on an Arch-based distro (Parabola, ...), you would run as root
|
|
|
|
pacman -S macfanctld
|
|
|
|
and don't forget to enable it by using `systemctl` or by a script that will run macfanctld if using runit.
|
|
|
|
Then, you want to install powertop and tlp.
|
|
And then, run the following on battery
|
|
|
|
sudo tlp start && sudo powertop --calibrate
|
|
|
|
Then, after quitting powertop, run :
|
|
|
|
sudo powertop --auto-tune
|
|
|
|
Now, configure tlp, edit the `/etc/tlp.conf` and uncomment/add/modify the following:
|
|
|
|
CPU_BOOST_ON_AC=1
|
|
CPU_BOOST_ON_BAT=0
|
|
|
|
SCHED_POWERSAVE_ON_AC=0
|
|
SCHED_POWERSAVE_ON_BAT=1
|
|
|
|
PLATFORM_PROFILE_ON_AC=performance
|
|
PLATFORM_PROFILE_ON_BAT=low-power
|
|
|
|
The MacBook will still overheat, just less.
|
|
|
|
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.
|
|
|
|
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"
|
|
