Reset Lost password

First up, you need to reboot your computer while holding the Command and the R keys down. Hold your Mac’s power button down for about six seconds, and it will turn off. Wait a couple of seconds more, and then hold down Command-R on your keyboard while pressing the power button again to turn the machine on. Keep holding the Command-R combination until you see the little spinning circle just below the Apple logo on the boot up screen.

Once your Mac boots, you’ll see a window with various options. Use your mouse to select Terminal from the Utilities menu, and Terminal will launch. Type in

resetpassword

and you’ll get a dialog box that will let you do just that. Choose the user you want to change the password for, and type in the new password twice. Hit OK, close the reset password window, and reboot your Mac.

Locked Files in MacOSX

When a file is "locked" by OS X, it is applying what *nix calls a "flag" to the file. In this case, the flag is "uchg", which means that no user, even root, can alter the file in any way until the flag is removed. You can use the command chflags to remove the flag.

The following example should unlock every file in your home directory:

sudo chflags -R nouchg ~/
Here's a breakdown of the command:

sudo will run the chflags command as root (you may be prompted for your root password).

-R will cause the command to affect every file in the directory and all of its subdirectories. Yes, capitalization matters.

nouchg is the syntax for removing the uchg flag. Any flag can be removed by putting "no" in front of it.

You can of course substitute the tilde (~) with whatever directory path you want to affect. To change an individual file, leave out the -R and type the file path instead of a directory path. Normal operators apply, such as $ and *.

Apache2 - Mac osx

Apache cofig file is found in the private/etc/apache2
it is a hidden directory under the root. you can access it by Clikcing "Go" under the menu and then click "go to folder" Then type in the directory..
you have to change the ownership of the file in order to modify it. I had to login as an ftp user to changer the file.
