We get the question or comment quite a bit that people are planning to purchase a Mac and want to run Ubuntu (or some other variant of Linux) on it exclusively. Now, this can be done, and you might end up with exactly what you want in the end, but I have to say, “Why in the world would you do that?”

Don’t get me wrong, I like my iMac, and I am even getting a Macbook Pro soon for work. I also like running Ubuntu on my iMac, but buying a Mac just to use Linux just doesn’t make any sense to me. There are so many other options out there for a linux-specifc application. With Dell now offering machines made specifically with Linux compatibility in mind in addition to the several linux-compatilible hardware vendors out there, it is way too easy to obtain hardware that can coexist with linux peacefully.

Knowing your Mac version is very helpful when asking for help in forums or mailing lists since hardware changes are made when Apple decides to update their machines.

Just use the following command. (I use Ubuntu by the way)

sudo dmidecode| grep Product

In the output, you should have a line that looks similar to:
Product Name: MacBookPro2,2

and in this case the version would be: MacBookPro2,2

Apple must really be trying to get rid of the Airport Extreme technology:

The Apple Store (U.S.) – AirPort & Wireless (20080209)

Here is a screenshot in case it gets changed

Apple Airport Extreme Cards Must Sell!

Introduction

Intel Macs use EFI (Extensible Firmware Interface) instead of the typical BIOS (Basic Input / Output System) that most PCs use. EFI has a standardized specification that, unfortunately, Apple, in their infinite wisdom, decided that they do not need to abide by, and slightly modified their implementation. This makes developing Linux software that interfaces with this system difficult. In fact, there is, as of yet, no reliable method of booting Linux directly through EFI although work is being done by the mactel-linux group, elilo, and Grub2 to allow for this functionality. Part of this system is the use of a partitioning system called GPT (GUID Partition Table) which is used in place of the MBR (Master Boot Record) that would coincide with the use of a BIOS. NOTE: GUID means Globally Unique Identifier, which is basically a unique number that is used to identify something, a partition in this case. There is not much more that is needed to understand about that. Apple also places an “EFI partition” at the very beginning of the disc. This is used as a location to place executables for the EFI system to perform firmware updates. Read the rest of this entry »

This question gets asked a lot, especially since people are having non-functioning keyboards in Linux Bootloaders (Windows too). If you make room on your Intel Mac to boot Windows and Linux, most distros will now detect windows and add an entry to grub and/or lilo, and install the bootloader to the MBR (Master Boot Record) of your disk. This is ok on most PCs, as there is not normally any other way to choose which OS you want when booting up. However, most Mactel multibooters are using rEFIt to select the OS, and there is no need to use grub for anything but Linux (and hopefully, a EFI native bootloader will be available someday to replace that).

The way to get around this annoyance is to install your Linux bootloader to the root partition (or your /boot partition if you have one), and leave the normal Windows bootloader in the MBR. I use Ubuntu and Grub, and will focus there, but these general instructions should work for any system.

Here I am posting a lot of information about my iMac for configuration in linux. Hopefully this will help a few people out that are wanting to try out linux on their Macs. I use Ubuntu linux, so all of this information has been tested only under that system. I am currently using 7.04 Feisty Fawn, although 7.10 Gutsy Gibbon will be released soon and seems to be running OK on my model Mac at the moment.

First, you can download my fully verbose lspci here.

The display built into the iMac is essentially a 20″ Apple Cinema Display. The following are the correct entries for the xorg configuration file including specific modelines as found on the Gentoo hardware wiki:

Section "Monitor"
    Identifier      "Apple Cinema Display"
    VendorName      "Apple Inc."
    ModelName       "Apple Cinema Display 20"
    HorizSync       28-90
    VertRefresh     43-72
    DisplaySize     434 270
    Option "DPMS"
    UseModes "Modes0"
EndSection

Section "Modes"
    Identifier "Modes0"
    ModeLine "1680x1050" 119.00 1680 1728 1760 1840 1050 1053 1059 1080

I recently compiled a kernel for linux 2.6.22.6 with the latest mactel and ck patches. My config can be downloaded here: config-linux-2.6.22.6-mactel-ck1

I know this is kinda trendy, but I had an old Clamshell iBook that ended up just sitting around for a very long time, so I decided to use it to make my own digital picture frame. Read the rest of this entry »
