* Boot in Verbose mode: on boot, hold down Apple + V. Watch for errors as Mac boots, and google any errors found.
 
* Drain power cache: with computer off, take out battery, unplug from charger, and hold down power button for 15 seconds. Can sometimes fix a Mac that won't boot.
 
* Delete a program's .plist settings file: Found either in ~/Library/Preferences or in /Library/Preferences. This clears all settings for a program.

=== Hardware troubleshooting with Apple Diagnostics ===
+
== Reinstalling Mac OSX ==
* On newer models, you can start diags by pressing F2 on booting. (Diags are preloaded onto computer.)
 
* On older models, insert the install disk and hold down the D key while booting. Diags are model-specific so you can't use the wrong CD.
 
* AppleCare-covered users can download and install TechTool Deluxe for free. A good diagnostic but to convince Apple of system failure, you'll need to use the more official Apple diagnostics.
 
  
=== Blinking Question Mark ===
+
* Students must use the DVD that came with their computer. If a student cannot find this, they should call Apple and they will send a new one. Each install disk is specific to the computer model, so the install disks that the Helpdesk has won't work on a student's computer.
 +
* For faculty and staff, we can reimage Mac computers using our image on the server.
  
*Symptom: Your Mac won't start up. You see a white or gray screen with a blinking/flashing question mark.
+
== Keyboard shortcuts in Mac OSX ==
*Cause: The Mac cannot find the operating system. '''Most likely the hard disk has failed.'''
 
*Solutions: It's worth to try the following:
 
  
==== Diagnosis ====
+
A reference (PDF) to common Mac keyboard shortcuts is available here: http://davespicks.com/writing/programming/mackeys.pdf
  
*Reset the PRAM (http://support.apple.com/kb/HT1379)
+
You can also change keyboard shortcuts on a Mac:
*(if this is a MacBook) Reseat the hard disk (Instructions: http://manuals.info.apple.com/en/MacBook_13inch_HardDrive_DIY.pdf)
 
*Try putting the Mac in [[Target Disk Mode]] and connect it to another Mac, then run Disk Utility [http://www.macworld.com/article/133496/2008/05/firstaid.html How to run disk utility]
 
*If the owner has the original install DVD, it can be used to repair the OS (http://support.apple.com/kb/HT1710). '''The Helpdesk DOES NOT have a collection of install DVDs so they cannot help if the owner does not have the install DVD.
 
*If none of the above helps, then '''it is very likely that the hard disk has failed'''.
 
  
==== Recovering Files ====
+
# Click on the Apple symbol on the menu bar -> System Preferences -> Keyboard
If you need to get files from the computer, you can:
+
# Click on the Keyboard Shortcuts tab. You should see a list of keyboard shortcuts.
 +
# Double-click on the appropriate short-cut and hold down the new keys for your shortcut.
  
*Try putting the Mac in [[Target Disk Mode]] and connect it to another Mac to copy your files.
+
== Languages and international input on Mac OSX ==
**This '''may not work''', and if it does not, it is an indication that the hard disk has failed completely.
 
*If the data on the computer is very valuable, the owner can decide to contact [[Data Recovery#Professional_Data_Recovery_Services|a Professional Data Recovery Service]].
 
*See below for repair options.
 
  
==== Repair ====
+
==== Configuring keyboard inputs ====
  
*If the computer is under warranty, the owner must contact Apple directly (call 1-800-275-2273 OR visit the Apple-authorized repair center in South Burlington: [http://www.smalldog.com/contact Small Dog Electronics].
+
# Apple menu -> System Preferences -> International
*If the computer is not under warranty:
+
# Under the Input tab, look for the desired input method on the list. Check the checkbox next to it. The input switcher icon will appear to the left of the clock.
** Self-repair or repair at the Helpdesk: depending on the model (any MacBook, late 2008 MacBook Pro), it may be possible to replace the hard disk at the Helpdesk. The owner needs to purchase a replacement hard disk (see [[Purchasing Replacement Parts#Apple]])
+
# If you want, you can also configure the keyboard shortcut to switch between languages. Look in System Preferences -> International.
** '''For a fee''', Apple or Small Dog can repair the computer: contact Apple directly (call 1-800-275-2273 OR visit the Apple-authorized repair center in South Burlington: [http://www.smalldog.com/contact Small Dog Electronics].
 
  
==== Prevention and safeguards ====
+
* Show the '''on-screen keyboard''': Click on the input switcher menu near the clock, then look for "Show keyboard" menu item. If it's not there, try going to System Preferences -> International -> Input and look for an item on the list to enable that says "Show Keyboard".
  
Hard disks eventually fail, even when best care is taken. The best solution is to purchase an external hard drive and do regular backups. External hard drives often come with software that makes the backup process automatic. External hard drives can be purchased from http://www.amazon.com http://www.newegg.com - almost any on-line shopping site sells them these days. Good brands (no particular order): Western Digital, Seagate, LaCie...
+
==== Change the system language ====
  
=== For hard drive failure ===
+
This will change the language of all messages, menu items, etc. that make up the interface of your computer. Changes will only apply after you log out and log back in to your user account.
  
==== Check disk ====
+
# Apple menu -> System Preferences -> International
# Boot into Single User Mode by holding down Apple + S on boot.
+
# Under the Languages tab, look for the desired language on the list. Drag it to the top of the list, then log out and log back in to your account.
# When system has loaded, enter <code>fsck -fy</code> to check disk.
 
  
==== Target Disk Mode ====
+
== Taking a screenshot in Mac OSX ==
See [[Target Disk Mode]] for how to use. Boot a Mac using another Mac's hard drive so you can:
 
* Access the internal hard drive without depending on it to boot the system
 
* Run Disk Utility to repair disk permissions
 
* Run Disk Warrior for advanced repair techniques
 
  
==== Archive & Install ====
+
* To take a picture of the entire desktop, press '''APPLE + SHIFT + 3'''.
Reinstalls system without touching user files (in theory). A messed-up install might be fixed this way.
+
* To take a picture of just a partial rectangle of the screen, press '''APPLE + SHIFT + 4'''. You will now be able to click and drag to select a rectangle to capture.
 +
* The picture will appear on the the desktop as a file with a name like "Picture 1". You can attach this picture to an e-mail message and send it to the helpdesk.
 +
* Another way of taking a screenshot on a Mac is using Apple's built-in&nbsp;Grab application: http://docs.info.apple.com/article.html?path=Mac/10.4/en/mh364.html
