Fix an unusually dark projector image

Send by email

We have noted the following problem with Mac OS 10.6 (Snow Leopard) and certain data projectors on campus (Gerlinger, US Science "Curie"). The image appears ununsually dark, as pictured below.

Normal Image Dark Image

Mac OS 10.6.3 and above uses a new method to determine the gamma level of the display, one aspect of color calibration that determines the "black point" of an image. This problem appears in the more complicated projector setups we have on campus, where many connections exist between the computer and projector. To fix the problem, manually select a color profile that looks better for your projector.

Open System Preferences -> Displays

Select Arrangement and then uncheck Mirror Displays so that the Displays window looks different on the projection screen from your laptop computer.

On the projector Displays window, select the Color tab. Uncheck Show profiles for this display only.

Select one different profile in the list at a time until the image looks more normal.

Return to Arrangement and check Mirror displays as before.

If this color profile does not load automatically in the future, then ask IT for help to create a custom profile for you.

What are the storage limits?
 

The per user disk storage limit is 10 GB. You will start to receive warnings when you reach 80% of your limit.

 

How can I find out how much of my allotted disk space is left?

 

For PC users, open My Computer, and the Free Space Column tells you how much disk space you have left on the drive.

For Mac users, open your server folder, and the text at the bottom of the window tells you how much of your limit remains.

How can I find out what is taking up all that space?

Authentication Required -- Printing in Mac OS 10.5/10.6 Leopard and Snow Leopard

posted in
Send by email

What to do when a print job won't print and the status is "on hold - authentication required"

 

Printing to Windows printers got a little more complicated with Mac OS 10.5 (Leopard). You have to save your password for each printer you use, as follows. Ideally, you should only have to do this once.

If you send a job to print and it doesn't come out, check the following.

Open the printer using its dock icon.

You should see a window similar to this.

Look down at the print job list. See that text under Status that is difficult to read?

Expand it by dragging the vertical dividing line between Status and Name.

 

If you do not see any print jobs listed, try going to the Jobs Menu and selecting "Show Everyone's Jobs."

 

The job requires a password. Click Resume.

Now the password dialog box pops up. Enter your Catlin Gabel username (kassissiehr not Richard Kassissieh), enter your email/network passowrd and check "remember password" (if you are NOT using a public/shared machine).

Charge laptops in green Middle School mobile cart

posted in
Send by email

Why don't the laptops in the green cart get fully charged?

In response to a report that the green laptop cart was not charging computers effectively, I made two changes and one discovery that should help you get the laptops fully charged for the start of each class period. This leads to the following tip, which Lynda has very kindly taped to the top of the cart.

When you return laptops to the green mobile cart, flip the black power switch on the side of the cart to "off” then immediately back to "internal.” Confirm that the orange or green lights on the computer power adapters are lit, indicating that they now have access to power.

See the following diagram for the location of the black switch (circled in red).

Here is the full explanation. The problem was that the cart was only charging half of the laptops at a time. I rewired the power adapters so that the computers are all on the same circuit within the cart, so that they should all now charge at the same time. The discovery was that the cart has an internal timer that causes it to alternate the halves of the cart that are being charged. In order to prevent the cart from charging the side that is now unused, I lengthened the time interval to 100 minutes and discovered that you can reset the timer by flipping the cart power on and off.

Openwireless

Openwireless is Catlin Gabel's public wireless network.

 

The "openwireless" network is designed to provide internet access to parents, visitors, and friends of the school. Students and employees should use wireless network named "catlingabel."

Openwireless is not on our local area network. It provides access only to the internet. If you connect to openwireless, you will not be able to print, access the file server, or run Microsoft Outlook. Openwireless will behave much as your internet connection from home. You will be able to access the Catlin Gabel web sites, including insideCatlin, through openwireless.

Openwireless is an unprotected, unsecure network. It requires no password, nor does it encrypt traffic. This means that one should not use openwireless to transmit sensitive information, unless you are connecting via a secure (https://) web site.

Full network users (students and employees) will normally not find it necessary or desirable to connect to openwireless. Parents and school guests will find it useful. However, if you cannot connect to cgs and can live with internet access only, then you may find it useful to have a second option. How can you find out what network you have attached to? On a Mac, check the Airport icon in the menubar. On a ThinkPad, open IBM Access Connections in the task bar.

Maximize your battery life (Mac)

posted in
Send by email

 

Your Apple battery is a "Consumable" product that decreases in performance over time. However, there are several things you can do to improve the performance and the life of your battery.

1. Your laptop works best between 50°F and 95°F. If you use your notebook in temperatures higher than its specified operating range, you may permanently damage your battery's capacity. You may damage it even more if you charge the device in these temperatures. Even storing a battery in a hot environment can damage it irreversibly. Using your laptop in a very cold environment may also decrease battery life. Unlike a hot environment however, this is a temporary condition. Once molecules in the battery warm up, the battery will return to its previous capacity.

2. For proper maintenance of a lithium-based battery, it's important to keep the electrons in it moving occasionally. Apple does not recommend leaving your portable plugged in all the time. An ideal use would be a commuter who uses her iBook on the train, then plugs it in at the office to charge.

3. Recondition your battery by letting your battery run to less than 3% at least once a month. Reconditioning the battery can restore some of your battery capacity

4. If you don't plan on using your notebook for more than six months, Apple recommends that you remove and store the battery with a 50% charge. If you store a battery when it's fully discharged, it could fall into a deep discharge state, which renders it incapable of holding any charge. Conversely, if you store it fully charged for an extended period of time, the battery may experience some loss of battery capacity. Be sure to store the ejected battery at the proper temperature.

5. Brightness: Dim the screen to the lowest comfortable level to achieve maximum battery life. For instance, when watching a DVD on an airplane, you may not need full brightness if all the cabin lights are off. AirPort Wireless: AirPort consumes power, even if you are not using its features to connect to a network. You can turn Airport off in the control panel to save power. Bluetooth Wireless: Likewise, you can turn off Bluetooth to maximize your battery life, as it also consumes power when not in use. CD's: Having a CD in your CD drive, even if it is not in use also consumes battery power because the computer will constantly verify the presence of a CD. Remove CD's when not in use for extended battery life.

Your Apple laptop comes with a Lithium-ion battery which uses a "fast charge” to charge your device to 80% battery capacity, then switches to trickle charging. You can charge all Lithium-ion batteries a large but finite number of times, as defined by charge cycle.

A charge cycle means using all of the battery's power, but that does not necessarily mean a single charge. For instance, you could use your laptop for an hour one day, using half its power, and then recharge it fully. If you did the same thing the next day, it would count as one charge cycle, not two, so you may take several days to complete a cycle. Each time you complete a charge cycle, it diminishes battery capacity slightly, but you can put laptop batteries through about 300 full charge cycles before they will only hold 80% of original battery capacity (if battery is properly maintained). As with other rechargeable batteries, you may eventually need to replace your battery. (Information from www.apple.com/support) Average laptop battery life experienced by student at Catlin is approximately 1.5 to 2 years.

MacBook Pro: MacBook Pro computers become very warm when under high performance conditions or when charging. It is important that you do not let your computer overheat during these times.

Back up your files! (Mac)

posted in
Send by email

How to back up your Mac files to a variety of devices.

Why back up?

It is important to back up all your files and documents on a regular basis. Hardware and software DOES FAIL and can destroy documents. Viruses can also corrupt or delete documents. It is very difficult to recover files and your best insurance that you do not lose data is to make a backup of all your files on a regular basis. (At least once a week, or more if you are working on a document that you would not want to lose.)

Where should I back up?

You have a number of choices: your network user folder, external hard drive, CD, DVD, or USB flash drive. Your choice will depend on how much data you have and how long you plan to keep it. If you have tens of gigabytes of data and want to keep a permanent backup, an external hard drive is your best option. If you have just a few gigabytes of data, then the network is an excellent backup location. CDs and DVDs are very portable, long-lasting, and inexpensive. If you only need the backup for a short time, then a USB flash drive is appropriate.

Automatic or manual?

It's easy to forget to back up. With backup software such as Silverkeeper, you may schedule a daily backup. Please follow the preceding links for more instructions on how to correctly configure these backup utilities.

Archive or separate files?

Archiving files and folders creates a copy of the items you want to back up in a compressed file. Archived files take up less disk space than uncompressed files and can help you avoid naming problems if you copy from a Macintosh computer to a Windows server. Archive if you are short on space or are having file naming problems. Otherwise, you may be just fine copying plain files.

  • Select an item or items in the Finder.
  • Choose File > Create Archive.
  • If you archive a single item, the archived file has the name of the original item with a ".zip" extension. If you archive multiple items at once, the archived file is called Archive.zip.

When you open an archived file, your computer displays uncompressed copies of the original items.

Back up to the server

Advantages: located at school, automatically available to you

Disadvantages: not available from home, not enough space for music or videos. Please back these up to other media.

  1. In the Finder, navigate to Go menu -> Connect to Server (or type Command-K on your keyboard)
  2. Select the server shortcut to your user directory or type smb://cgsfiles01
  3. Select Connect
  4. Enter your username and password at the prompt. (The same ones that you use for your email.)
  5. If necessary, select your class year from the next menu (e.g., 2010) and click OK.
  6. A new icon for the server volume will appear somewhere on your desktop.
  7. Double-click the new server volume to open it, then double-click on your user folder (your last name and first initial).
  8. Create a new folder for your backup (we recommend dating it as well).
  9. Drag any or all of your documents into this folder. Make sure that the mouse changes to the plus icon instead of the shortcut icon . If it does not change to the plus, hold down the Option key while dragging the files.
  10. If you get a message stating that this folder already contains a folder with the same name, click Yes to All.
  11. Once all your files are copied, your backup is complete!

Back up to an external hard drive

Advantages: greatest storage capacity, fast

Disadvantages: additional cost, usually kept in one location

  1. Connect the hard drive to your computer.
  2. Switch the hard drive power on.
  3. An icon will appear on your desktop for the device:
  4. Drag and drop files into the icon.
  5. When you are done, drag the icon into the Trash
  6. The Trash icon will change into an Eject icon.
  7. Turn the hard drive power off.
  8. Disconnect the hard drive from your computer.

Please refer to external hard drive care and feeding for more information.

Back up to CDs or DVDs

Advantages: portable, long-lasting

Disadvantages: slow to copy data, must use a new disc each time, 750MB capacity per CD, 5GB per DVD

  1. Insert a CD/DVD into your CD/DVD drive (your machine must be capable of burning CDs or DVDs).
  2. A menu will appear on your screen, select "Open Finder” and press OK
  3. A CD icon will appear on your desktop.
  4. Drag any or all of your documents into the CD. Make sure that the mouse changes to the plus icon-> instead of the shortcut icon -> . If it does not change to the plus, hold down the option key while dragging the files.
  5. When you are finished drag the CD icon to the trash. The trash icon will turn into the burn icon.
  6. Another menu will appear. Change the Disc Name and Burn Speed if desired and then press Burn.
  7. Remove the CD from your computer and store it in a safe place where it will not be scratched!

Back up to a USB Storage Device

Advantages: quick, very portable

Disadvantages: small capacity, susceptible to static electricity, only reliable for short-term storage

  1. Insert the device into your USB port on the side of your computer.
  2. An icon will appear on your desktop for the device.
  3. Drag and Drop files into the icon.
  4. When you are done, drag the icon into the Trash
  5. The Trash icon will change into an Eject icon.
  6. Remove the device from your computer and store it in a safe place!

 

Run Entourage From Off-Campus

Send by email

Configure Entourage to access the Catlin Gabel Exchange server from off-campus.

Mac users, you don't have to use webmail! Entourage is Microsoft's
email and personal organizer application. You may configure Entourage
so that it will work from both on and off-campus. People generally
prefer a desktop mail application to webmail because it checks for new
messages automatically, supports keyboard shortcuts, and handles
attachments more easily.

Open Entourage and go to Tools --> Accounts.

Select your Catlin Gabel account and click Edit.

On the Account Settings tab, change Exchange Server to:
https://webmail.catlin.edu/exchange. "This DAV Service ..." checkbox will automatically turn on. This is good.

On the Advanced tab, change Public Folders Server to:
https://webmail.catlin.edu/public

Confirm that LDAP server is set to cgsdc01 (address book lookups only work from campus).

Click OK and close the Accounts window to save your changes. It may take a few minutes for your mail to reload from the server.

p.s.
You can also increase how often Entourage checks for new mail under
Tools -> Schedules -> Send & Receive All -> Edit.
