|
The MacBook1,1 and MacBook2,1 are very similar to the
|
|
ThinkPad X60. It shares some hardware with the X60 such as the chipset.
|
|
|
|
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
|
|
=============
|
|
|

|
* MB062LL/A / A1181 (EMC 2139) / Intel Core 2 Duo T7400 *(tested -
|
|
working)*
|
|
|
|
It's believed that all MacBook2,1 and MacBook1,1 models work fine with
|
|
Libreboot. If there's a model not in the list or not confirmed working
|
|
here and you happen to have that model and that model works with Libreboot
|
|
then don't forget to [send a patch](../../git.md), confirming that it
|
|
actually works!
|
|
|
|
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
|
|
|
|
The MacBook1,1 can't be flashed internally if running the Apple EFI firmware.
|
|
You must flash externally.
|
|
|
|
External flashing
|
|
=================
|
|
|
|
MacBook1,1 requires external flashing, if running the default Apple firmware.
|
|
MacBook2,1 can be flashed internally, regardless.
|
|
If running coreboot or libreboot you can already internally re-flash.
|
|
|
|
[This page shows disassembly
|
|

|
|
|
|
Locate the flash. It'll be a SOIC8, which looks like this:
|
|
|
|
|
|
|
|
The chip is located under the motherboard. [How to remove the
|
|

|
OSes using Linux on Apple EFI firmware
|
|
======================================
|
|
|
|
You have 2 choices for booting up OSes using Linux as their kernel
|
|
on the MacBook:
|
|
|
|
* Boot via USB ;
|
|
|
|
* Boot via a CD or DVD.
|
|
|
|
Boot via a CD or DVD
|
|
--------------------
|
|
|
|
The Apple EFI firmware contains a PC BIOS emulation layer for booting
|
|
Microsoft Windows on CDs and DVDs. That emulation layer **only** works
|
|
if booting from a CD/DVD or from the hard drive. The MacBook will **not**
|
|
boot MBR bootloaders from USB, which is why booting from a CD or DVD is
|
|
easier than booting from a USB.
|
|
|
|
* First, burn your ISO to a CD or DVD ;
|
|
|
|
* Reboot and while rebooting, hold down the Alt/Control key, a boot menu
|
|
should pop up, requesting you to choose which device to boot from ;
|
|
|
|
* Select the CD/DVD icon with 'Windows' as the label (the Apple EFI firmware
|
|
elways recognises CDs/DVDs using MBR as 'Windows', because the emulation
|
|
layer was made specifically for booting Microsoft Windows as part of
|
|
BootCamp, a tool which allowed dual-booting Windows and OS X) ;
|
|
|
|
* Install it like you normally would (If there's an OS X installation then
|
|
it's highly recommended to save all your data and wipe it. Libreboot isn't
|
|
able and will never be able to boot OS X) ;
|
|
|
|
* While rebooting, hold Alt/Control once again, and select the hard disk
|
|
icon with the 'Windows' label, after each subsequent boot, the Apple EFI
|
|
should boot up properly automatically.
|
|
|
|
*If you installed your OS alongside OS X then you won't be able to boot
|
|
to it using GRUB, despite the fact that it does sometimes show up. You
|
|
also won't be able to boot it up when using Libreboot.*
|
|
|
|
Boot via USB
|
|
------------
|
|
|
|
This method is harder than booting from a CD/DVD and may soft-brick your
|
|
MacBook but it's the only way to boot up successfully from a USB.
|
|
|
|
The PC BIOS emulation layer found in the Apple EFI firmware doesn't work
|
|
when booting up from a USB stick. Despite the fact that the
|
|
MacBook2,1 does use a 64-Bit processor, the firmware only supports booting
|
|
32-Bit EFI devices, meaning you're stuck with 32-Bit OSes and rare
|
|
64-Bit OSes which have ISOs that still support booting from 32-Bit EFI.
|
|
Meanwhile, GRUB fully supports booting up 64-Bit OSes on 32-Bit EFI.
|
|
|
|
* First, search for an ISO that supports 32-Bit EFI while being 64-Bit or
|
|
a normal 32-Bit ISO and put it in your USB stick ;
|
|
|
|
* Reboot and while rebooting, hold down the Alt/Control key, a boot menu
|
|
should pop up, requesting you to choose which device to boot from ;
|
|
|
|
* Select the USB icon ;
|
|
|
|
* Install it like you normally would (If there's an OS X installation then
|
|
it's highly recommended to save all your data and wipe it. Libreboot isn't
|
|
able and will never be able to boot OS X) ;
|
|
|
|
* Reboot. It should boot up to your newly-installed system if you wiped OS X,
|
|
else, hold Alt/Control and select the correct boot device ;
|
|
|
|
* Flash Libreboot. DO NOT REBOOT AGAIN BEFORE FLASHING. Sometimes the
|
|
firmware can get confused, because Apple never intended to boot other
|
|
EFI OSes other than OS X, as such there's a chance that your MacBook can
|
|
become [soft-bricked](https://apple.stackexchange.com/questions/408104/late-2006-macbook-doesnt-turn-on-fan-spinning-but-no-chime/409754).
|
|
If that is the case then dissassemble it and remove
|
|
the CMOS/PRAM battery, wait a few minutes, and put it back in.
|
|
|
|
*If you want to install Libreboot with the SeaBIOS payload then be sure
|
|
to reconfigure GRUB2 correctly, else your system won't boot.*

Coreboot wiki page
|
|
==================
|
|
|
|
The following page has some information:

|
|
|
|
Issues and solutions/workarounds
|
|
================================
|
|
|
|
There is one mouse button only, however multiple finger tapping
|
|
works. 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 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, 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 Debian 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 Arch-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"
|
|
EndSection
|
|
```
|
