Upgrading Mac OS X Snow Leopard on the Dell Inspiron 1525 to 10.6.4

================================================================================

In this part of the guide, I’ll be covering upgrading to 10.6.4. You can read
the first part of this guide here - Installing Mac OS X Snow Leopard on the Dell
Inspiron 1525

Upgrading using the 10.6.4 combo-update

This is probably the easiest method. Download the 10.6.4 combo-update from here
- http://support.apple.com/kb/DL1048

While that downloads, you’ll need to prepare some things.

Download the kernel-independent version
of SleepEnabler.kext - http://code.google.com/p/xnu-sleep-enabler/downloads/detail?name=SleepEnabler.10.6.x.zip

You will need to put this SleepEnabler.kext into /Extra/KextStore/ Copy your
com.apple.Boot.plist from /Extra/ to your desktop and open it in TextEdit. Add
the following between <string></string> under <key>Kernel Flags</key>:

pmVersion=20

So it will read:

<key>Kernel Flags</key>
<string>arch=i386 pmVersion=20</string>

Then copy the com.apple.Boot.plist back to /Extra/.

Delete IO80211Family.kext from /System/Library/Extensions — you can do this
through the terminal by opening Terminal.app and executing the following
commands, and entering your password when prompted:

$ cd /System/Library/Extensions
$ sudo rm -rf IO80211Family.kext
$ sudo rm -rf SleepEnabler.kext

After these things are done, and the 10.6.4 combo-update has downloaded, you can
start the installer. It will take a little while, so go grab a coffee while it
installs. After the installer completes you will need to reboot.

Now you should have 10.6.4 installed, you can check for software updates and
install any remaining updates.
