MCS for Mac OSX

Check what version of Mac OS X you have by clicking the apple in the left-most corner of the screen and then selecting “About this Mac”. A window will pop up and it will tell you what version of the operating system you have in this format: 10.X.x. (OS X 10.8 Mountain Lion, OS X 10.9 Mavericks, OS X 10.10 Yosemite, OS X 10.11 El Capitan, macOS 10.12 Sierra, macOS 10.13 High Sierra). The last number refers to software updates.

The following instructions are steps you must take now to ensure that your computer will be safe from viruses and other malware.

If you have arrived with an infected computer, or if it becomes infected while you’re here, you may lose access to the Internet until you clean it up. This may require you to reformat your hard drive and reinstall your operating system and all your applications from scratch. It’s up to YOU to take the necessary precautions to secure your computer.

Before Connecting to the Network

Step 1: Turn on Built-in Firewall

OS X 10.8 Mountain Lion, OS X 10.9 Mavericks, OS X 10.10 Yosemite, OS X 10.11 El Capitan, macOS 10.12 Sierra, macOS 10.13 High Sierra.

  1. Open System Preferences by selecting it from the Apple menu (click the little apple symbol located upper left corner) or clicking it in your Dock.

  2. Select or search for Security & Privacy.

  3. Click on the Firewall tab.

  4. Click the lock on the bottom left hand corner and enter your computer password to unlock it (if it is not already unlocked).

  5. Click Turn On Firewall.

    Step 2: Turn On Automatic Software Updates

    The following instructions will explain how to turn on automatic software updates. This will make it easier to keep up with critical updates that are released to protect your machine from dangerous viruses and other malicious programs.

    Every time your computer finds new updates, you will see a notification message on your screen that new updates are ready to be installed. Do not ignore this software update message! Just say yes and allow the installation to proceed. After the installation is complete, you will usually be prompted to close down and restart your computer.

    By default, Software Update is enabled and configured for weekly updates. To confirm that it is set up to do so, please follow these instructions:

    1. From the Apple Menu, choose System Preferences.

    2. Select App Store. Ensure that Check for updates, Install app updates, Install OS X or macOS updates, and Install system data files and security updates are all checked. Choose Weekly from the menu on the same line.

    3. Close the window to save the settings.

    Step 3: Setting up a Personal Password

    In order to keep your machine safe from attacks, you need to protect all of its local accounts with secure passwords. A secure password is a combination of letters and numbers. It is something that would be very hard for you to forget, but virtually impossible for anyone else to figure out. If this password is forgotten, it cannot be reset. You may want to write it somewhere safe, but remember, if you write the password and keep it near your machine, anyone who finds it will be able to access all of your data and programs.

    1. Open System Preferences from your dock or from the Apple menu.

    2. Click Users & Groups in the System pane.

    3. Select the account whose password you want to change from the account list on the left.

    4. Click the Change Password... button if you see it. Type a new password in the Password field and re-type it in the Verify field. You may also enter a hint to remind you of the password should you forget it.

    5. Quit System Preferences, saving your changes.

    Connecting to the Barnard Wireless Network

    Step 4: Connect to Barnard Secure

    If you are on the Barnard campus, you can connect to the Barnard Wireless Network. BCIT provides two wireless networks: Barnard Guest (for visitors on campus, including Columbia students and faculty), and Barnard Secure (for members of the Barnard community). Wireless service on both Barnard networks is available everywhere on campus, except for the residence halls at Cathedral Gardens and 601 W. 110th St. There is no specific configuration that exists in those two locations to connect to Barnard Secure or Barnard Guest.

    1. Open System Preferences from your dock or from the Apple menu.

    2. Choose “Barnard Secure”.

    3. Enter your uni as the username and your myBarnard password as the password.

    4. When connecting, you will be prompted (once) to accept a security certificate from

    6. Select App Store.

    7. Click the Advanced button and drag "Barnard Secure" into the top position in the Preferred Networks list.

    Step 5: Updating the Operating System

    It is critical that you update your operating system regularly. Without doing so, your machine may not be stable and will be much more vulnerable to attack. In Step 2 of these instructions, you configured automatic updating of the operating system, but after connecting to the Barnard or Columbia networks for the first time, you must update manually.

    1. Click the Apple icon at the top left hand corner of your screen and choose App Store… from the drop down menu.

    2. Click Updates at the top of the window that appears and update your computer if a Software Update is available.
