Changing File/Folder Permissions and Privileges in OS X

Sometimes you want to move a file or folder from another computer to your Mac. And every time you want to change the information, move it or change it in any way it wants you to give Admin permission.

Every single time!

How annoying!

This is because the permissions for whatever reason are set to Read only. A good way to check is to see if you can rename it by clicking on the name. If you can’t it’s probably Read only. You can also check by right clicking on the file or folder and clicking Get Info. Check the Sharing & Permissions at the bottom of the window.


a.) Changing the Permissions for a File or Folder

To change your Permissions/Privileges just click where it says Read only and change the settings to Read & Write.



b.) Changing the Permissions for multiple files or folders

So method a.) is fine for one or two files or folders but what if you have ten or twenty or a couple of hundred? For months I did this painstakingly for each file and folder, muttering dark curses against stupid user privileges for ordinary files… until I found out that there is actually a way of doing this!!!

To change the Permissions of multiple files or folders:

  • Open a finder window showing the folder CONTAINING all the folders/files you want to change
  • Right click on the folder and select Get Info
  • Unlock all Settings by clicking on the lock in the bottom right corner and type your Admin username and password
  • Click where it says Read only and change it to Read & Write
  • Click the Settings button and choose Apply to enclosed items

  • It will ask if you are sure and warn you that you can’t undo this action, so click OK (if you are sure)

  • Click the lock again to lock the Settings again


Now you can change the name and extension of all the files in that folder and move them wherever you want without being asked for your Admin details all the time. Hurrah!

Ubuntu 10.10 – How to Reset your Administrator Password

I did get locked out of my Ubuntu system a little while back.  I’m not sure how, but the computer just wouldn’t accept my Administrator password.

Anyhow, this is for those of you who find yourselves, for whatever reason, in the same position.  Fear not!  For there are many pages about how to do this online.  But they are all slightly different which can get a bit confusing.  This is the way that worked for me.

1.)  Get to the boot menu.  This can be done in different ways depending on your setup.  Mine goes to Grub 2 menu by default.  If you are using a computer that doesn’t go to boot menu by default I think you can get there by pressing and holding shift during startup.

Your boot menu should look something like this:

2.)  You will either have a recovery mode or a single user mode option.  They can both be used in the same way.  Choose the option you have available and you should come to a menu like this:

3.)  Choose Drop to root shell prompt and press enter.

4.)  When it has finished loading you should be left at a root prompt like this:



5.)  Type passwd and then the username of the user you are changing the password for.

For example, if the username is ‘layla’ you type:

passwd layla 

Then press enter.

6.)  You will come to a prompt like this:



Type the password you want for this user and press enter.

IMPORTANT:  As you type there will be no movement on the screen.  This is normal.

7.)  You will be asked to retype the password.



Type it and press enter.  Again, there will be no movement on the screen but don’t worry that’s how it should be.

8.)  If you have typed the password correctly both times you will receive this message:



You should now be able to log-in as Admin again.
