marliwahoo Posted February 21, 2008 Share Posted February 21, 2008 I have just helped several noobs get started with Leopard. None of them, like me when I was new to osx86, new to back up kexts, before updating. Back up your kexts !! You have been warned.

marliwahoo Posted February 22, 2008 Author Share Posted February 22, 2008 If you are restoring from single user mode (-s at F8 prompt), its the same commands except type in this command before you do the above commands: Tiny change: I don't believe sudo is needed in single user mode. Because you are already root. I hope that's not nit picking. If it is sorry.

~pcwiz Posted February 22, 2008 Share Posted February 22, 2008 No, marliwahoo you are right -s puts you in #root command. But I can't help thinking that single user mode is dangerous. Anyone could go near your computer and destroy everything from single user mode.
