How do I backup my extensions?

I need to do this before I upgrade to 10.4.10.

I am new to mac but i think simply copy your ext folder under another name. only problem is if you mess up the update (as in just bad for your system) you won't get a hold of it and it won't matter at that point.

Correct me if am wrong guys.

you can do this command in the terminal..

1. sudo -s
2. type your password after
3. cp /mach_kernel /old
4. cp -R /system/library/extensions/* /backup
5. cp - R /system/library/loginwindow.app /backup

you will see the backup folder with all your extensions when you click on MAC Hd.

hope that helps..

If you eva mess up and you need to get to your backed up extensions or kernels, store the backup folder in your root directory and if you are new to OS X and the terminal, DO NOT create spaces when you rename your system drive.

These are the one I mostly encountered.

[1] wrong extensions or framework not compatible

- hit F8 after restart, at the command line, type: -s. Then follow the instructions.

[2] kernel not compatible. (this means you wont even have a chance to use the -s switch\command)

- boot from the install dvd and go to the to topbar under Utilities, there is a Terminal.app. From there you need to use this command: ls and navigate to the Volumes directory. From that directory, type: ls again and you will recognize your system drive. Now navigate to your backup directory and start replacing file.

All these are done using commands, which means no drag-n-drop. I assume that you know basic Unix commands? If not, then it's just easier to reinstall.
