Use networksetup to change AirPort networks from the command line - 1 views

  •  
    Sure enough:

    networksetup -setairportnetwork Airport 'Your SSID Here' 'Network Pa$$wOrd Here'

    did just what I wanted, and it did not require an administrator password or sudo. If you need to get a listing of all of the current Wi-Fi networks which are broadcasting SSIDs, you can use 'airport -s' for a list which will also show what security measures are used.

    By the way, if you aren't familiar with networksetup, you should definitely read up on it. It has a lot of features that could come in handy. It also wields a great amount of power, so be careful. The command listed above is fairly innocuous but there is a lot more it can do.

Change File Permissions using Terminal in Mac OS X - BrockWoolf.com - 6 views

  •  
    Changing file permissions on the Mac is something you need to know how to do if you want to create your own non-home directory only shares on the Mac. Leopard implements folder sharing similarly to the way SharePoints does. I find myself needing to change permissions regularly because certain programs like to change file permissions on their own. The Terminal is generally better for changing permissions because it is much faster and also because you have more control. Sometimes you may need to do this is the file permissions get messed up in Leopard's File Sharing under System Preferences.

10.4: Hide users from the login window via prefs - Mac OS X Hints - 4 views

  •  
    A hidden user is a user that can login to the system, but the account will not be displayed in the Login Window, where all of the other accounts on the machine are listed. In lab or work environments, it's often desired to have a hidden user that has Admin rights for administrative functions and/or other special circumstances.

Allow non-administrator users to add or remove printers | Mac Admin Corner - 3 views

  •  
    Apple added a "feature" to Leopard which restricts non administrator users from managing printers on their Macs. While this is desired behavior on a public machine such as a classroom, it is a problem for single user machines such as faculty, staff and 1:1 deployments.
    By default in Leopard, a non-admin user can not add or remove printers. They are also not able to hold or resume a print job. This is a problem if you want users to be able to add printers themselves, especially if they're bringing their laptops home.

Adjust Mac OS X display brightness from the Terminal - Matt [Danger] - 0 views

  •  
    One of the classrooms I maintain is comprised of 2.4Ghz iMacs (MB323LL/A) that are dual booted with Windows XP and Mac OS X. Sometimes when the workstations are restarted from XP to OS X the display brightness gets changed to its dim power saver setting. This requires the user manually increase the display brightness by pressing the F2 key, which is inconvenient. I haven't been able to determine the cause of this issue so I wanted to create a login hook to increases the brightness as a temporary fix.
    OS X doesn't ship with a command line utility that let's you change display brightness. Fortunately, Nicholas Riley has written a utility that uses OS X frameworks to accomplish this quickly and easily. Here's the code

Prevent Hard Disk Spindown Using PMSET - 0 views

  •  
    Using PMSET on Mac OS X, you can prevent your external hardrive from going to sleep (or spinning down). If you rock a notebook, and rely on an external enclosure, you probably know how annoying it is when your drive goes to sleep on you and it takes a good 30 seconds for it to spin back up again. More annoying is when Finder becomes unresponsive until this happens. If your drive is set to spindown every 15 minutes, then this ends up being downright maddening, and seriously cripples your workflow.

How to disable the built-in iSight Camera - OS X Daily - 0 views

  •  
    Most new consumer Macs come with a built-in iSight camera which can be used for all sorts of fun from video chatting in iChat, horsing around in Photo Booth, to third party apps like Gawker. Despite these fun and harmless uses, there are some security concerns with having a built-in camera particularly in academic and institutional settings, and because of this some System Administrators have taped covers over the iSight and even removed them from the machines entirely. Thankfully, there's a much easier way to disable the built-in iSight camera, all you have to do is move a file.
