Mi propio instalador USB de OSX Lion

One of the problems I found when building my hackintosh was installing the system. Before the OS came in a DVD, which I have, but the latest – Lion 10.7, is available only via digital download or a USB  stick for $ 70 dollars.

Since I had already bought the digital version (via the App Store) I am not going to pay for the USB again, but somehow I had to save my purchased OS to a “material” medium.

For the installation I ended up using a USB Sandisk 16 MB, but I want to avoid the hassle of not having a hard media installer. It is important to have this kind of installer, because you can not always have Internet access, and it is important to keep a physical copy.

With this in mind, I started looking for one of these devices on eBay, where anything can be found. Turns out the Apple branded USB stick also comes packaged with the Macbook Air, with Snow Leopard installer specific to this model, so it does not work with other Macs. This contraption has faster access speed than a normal usb stick, it has 8 MB, and its available by Chinese sellers between 25 and 60 dollars, sometimes pre formatted and sometimes with the original software.

As I found the price excessive – a 8MB USB stick retails from $10, I decided to keep looking, until I found one selling  for $ 5; at the end of the auction I paid $ 12.

Now comes the fun part: immediately after receiving it I connected the stick and proceeded to format it with Disk Utility, but the disk does not show, although it mounts on the desktop without problems. (!?)

Searching the Internet, I found out that you need a Windows program to unlock and format the USB – which is  ironic.

The program is called SM32Xtest, and is a mass formatter. The link to download it is here, and video on how to do it is this.
After this obstacle, it is very easy to go back to OSX, USB and format with GUID Journaled, and follow this guide to install Lion fresh off the shop.

One detail that caught my attention from the original installer for Macbook Air, is that iLife ’11 is included. It’s a great idea to have two installers in one place, so I searched for my iLife DVD, and proceeded to copy it. The problem is that the installation files are invisible within the packages folder, so I had to “show” invisible files to copy to the appropriate directory on the USB. Here is how to do it-

In terminal type: defaults write com.apple.finder AppleShowAllFiles TRUE
To make the changes work, type: killall Finder
To return to its original state: FALSE defaults write com.apple.finder AppleShowAllFiles

At the end, I made an alias of the installer and put it in the main directory USB. Now I have a universal Lion installer with the latest version (10.7.3) and iLife in one package, identical to the one Apple sells for $ 70, and had fun creating it.

I welcome your comments.
