I used the Kalyway 10.5.2 disc to do all this. Start by booting your disc, and select english, the go to the Disk Utility. You'll need to partition your HD with 2 partitions. 1 in Mac OS extended Journaled, and don't use the other. Reboot, remove the disc, and insert your Ubuntu disc.
Do your ubuntu install on the partition you left alone in the OSx86 installer. Do a 1GB Swap partition, and do the rest in EXT 3 and set it for "/". Let it do it's thing and then log into Ubuntu so we can get ready for OSx86. Once you are logged in, get the PC EFI you downloaded to your home directory. Open up Terminal and get ready to enter this:
$ sudo mkdir /boot/pc_efi
$ sudo cp ~/boot_v8 /boot/pc_efi
Ok. Now, press Alt+F2. Enter "gksudo nautilus". This let's you browse your computer as a super user. Go to System>Boot and put the "boot_v5" file there, and clost the window before anything gets messed with.
Next, open up a Terminal again. Enter "sudo gedit
/etc/grub/menu.lst". Enter this at the bottom of the file:
title Mac OS XSave it, and your done. Shut down, boot up the Kalyway disc, and go through the steps till you can click "Customize".
- Completely uncheck ‘Language Translations’.
- Expand ‘Kernels’ and select ONLY ‘kernel_9.2speedstep’.
- Expand ‘Graphics_Drivers’, expand ‘Intel_GMA’ and select ONLY ‘GMA950′.
- Completely uncheck ‘Audio_Drivers’.
- Expand ‘Networks_Drivers’. and select ONLY ‘RTL1000′.
- Completely uncheck ‘Mobo_Chipsets’.
- completely uncheck ‘Patches’.
Now click install, and skip the disc check so things will do faster. Now go grab a smoke, and find something to do for a while.
Now that is finished, we get to have some fun. Open up a Terminal and enter this:
sudo vi /Library/Preferences/SystemConfiguration/com.apple.Boot.plist
It'll show the file, press "i" to edit it, and under kernel flags, enter cpus=1 between the ><. Press Esc, and then hold Shift and then press "Z Z". That's done. Now run the Kalyway 10.5.3 combo update. DO NOT restart after it finishes. open the other installer you got with it and run it. Select the vanilla kernel, and install it. Now restart When you reboot, press escape to see the grub menu. Select Mac OS X and after that, let it go through that menu, then press F8 when you can. Type "update -v" and hit enter. It will reboot, and do thqt aagain. Once your back in OSX, Google Mac 10.5.4 and 10.5.5 updates. ONLY get them from the Apple site! the combo updates will brick your system! For the other 2 updates, before you run them in Terminal enter :
$ sudo su -leave that in the terminal while doing the updates each time. Press Ctrl+C to exit it to be able to reboot. Do that for both. After you do that, just follow any of the tuts for OSX on the Aspire One. BTW, there is a kext for the left SD card slot. Just Google it. Hopefully that will help out since every other tut I tried kept bricking OSX. If you have a question, message me at my new e-mail: firstname.lastname@example.org . Good Luck !
