    installing 12.04 on macbookair1,1

    Hello,
    I want to install ubuntu 12.04.1 on a macbookair1,1 (Apple MacBook Air "Core 2 Duo" 1.6 13" (Original) according to http://www.everymac.com/systems/appl...-13-specs.html ). And I have some questions.

    1. Reading this post
    http://ubuntuforums.org/showthread.php?t=1799460
    is it safe to put linux? particularly, how close to rumors are the claims that os x is far better than linux in 'micromanaging' this particular device, and using linux can lead to potential problems in the cpu voltage handling?
    2. grub vs efi: how's the story? is that correct that in any case I will have to maintain let's call it 'apple bootloader', and ony in a second part of the boot process give control to grub->linux?

    I don't know how to produce a bootable usb stick, namely when I do what he says with a usb stick in mrb or guid with ms-dos (fat) partition in both cases (is this correct?)
    I get the message "the inserted disk is not readable by this computer" (translation from Italian, but this is the meaning) after the dd process is completed (see the post), and when I restart pressing alt it only sees the hd-drive, and not the usb.

    4. is that correct to select the mac 64 bit version for this model? is there any other particular suitable version?

    Can anyone help me? in particular, anyone with (hopefully positive) experience with similar macbook and ubuntu versions?
    Thanks, N

    Ive read in several places that installing ubuntu on Macs is a lot of trouble. You need to know a lot.

    Alright, here we go.

    1. It is definitely safe to install linux on a Mac. I have been running linux on my Macbook Pro 7,1 for around two years, and nothing has gone wrong regarding the CPU, etc. However, it is crucial to remember that Linux was not written for apple computers, and there will always be some configuring to do. For example, your macbook running linux will have probably only around ~70% of the battery power compared to your macbook running OS X, simply because Apple optimized their operating system for those particular Macintosh laptops and the developers of Ubuntu did not.

    2. On my macbook pro, I kept the apple bootloader and installed grub on my linux partition. That way, when I boot up my laptop I can just hold down the option/alt key and I can choose which operating system to boot into. When I choose linux, I am then taken to the bootloader installed on my linux partition (in this case GRUB). I would recommend this method; however, you can install rEFIt while in OS X, which is a third party bootloader. That method works well, too.

    3. This link should be helpful to you.
    https://help.ubuntu.com/community/Ho...%20USB%20Stick

    4. I checked the specs of your laptop, and it looks like you only have 2 GB of RAM. Therefore you should run a 32-bit installation, not 64-bit. A 64-bit installation is best for computers with 4+ GB RAM.

    I hope this information helped.

    Cheers,
    Thomas

    Hi Thomas, thanks for your reply.
    about 3. my problem is that when I do
    Code:
    sudo dd if=/path/to/downloaded.img of=/dev/diskN bs=1m
    I get that error at the end of the process.
    about 4. I know it is 32bit, but I was thinking that maybe the 64bit-mac was somehow optimized for mac.

    Best, Nicolo'

    You should be able to use 64 bit.

    I've seen that page too, but it's basically the same as above; also, the error I get is not listed in the possible errors one could get (actually I get it when os x tries to mount the usb, and reads it as corrupt or something, I don't know if this is normal), while at reboot pressing alt just shows me the hdd

    at this stage, i'm not even able to boot, with or without refit. refit says basically 'the hardware refuses to boot': does anybody know a way to boot linux on this specific model from usb, without making new partitions and without the use of external usb dvd drive?
