Having installed Macintosh OS X on my Dell Mini 9 via the instructions here, the next challenge was to install the 10.5.7 update. Again using the mydellmini.com as my reference I waiting for other to try and install it. Conq was the first to get the steps up on the forum. Here is how to do it. I take no credit for this whatsoever.

Download the installer, don't use Software Update. Install 10.5.7, in my case i downloaded the Combo.

Let it reboot.

At the boot screen use the -x to enter Safe Mode. (You have to press esc on boot to have the option to type this in)

Remove custom dsdt.aml file (this file is on the root of the drive, just drag it to the bin)

After in Safe Mode run DellEFI. (I used version 1.1)

Do a customer install and, reinstall the Mini 9 Extensions, Install custom dsdt.aml file, and fix Bluetooth.

Reboot.

and all should be well.
