How to access ext2 or ext3 file system from Mac OSX

I have always wanted to access my Ubuntu harddisk in my Leopard. For months, google has been telling me not possible but, today came as a surprise, you are able to do so by installing fuse. Fuse is a user space file system which allows system to read different type of file system provided the developers has followed the Fuse inferface. It is originated from Linux and it has been ported to Max OS. Man, I really like FOSS. For more infor in fuse, http://fuse.sourceforge.net/

So to start, 

1. go to http://code.google.com/p/macfuse/ and download the latest version

2. go to http://sourceforge.net/projects/fuse-ext2/ and download the latest version. You should be able to download dmg format under the "Files" type

3. Install macfuse first

4. Install fuse-ext2

5. Reboot and you should be able to read ext2/3 formated drive.

PS: Just a note, there is another ext application for Mac however, I tried and it does not work for me.

How to install iPhone SDK 3.1.2 with xCode 3.1.4 on Mac OS X 10.5.5

After a clean install, I need to install the xCode with iPhone SDK again on Mac OS X 10.5.5. However, you should see an error telling you that it support 10.5.7 and above. To resolve this, you can do the following.

1. Edit the file /System/Library/CoreServices/SystemVersion.plist under superuser mode. I like to use vim

sudo vim /System/Library/CoreServices/SystemVersion.plist

The password should be your user password.

2. Change all the 10.5.5 to 10.5.7

3. Save and exit.

4. Start installing!
