* 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.

* See [https://support.apple.com/guide/mac-help/intro-to-macos-recovery-mchl46d531d6/mac Apple support article on Recovery]

== Keyboard shortcuts in Mac OSX ==
 +
 
 +
A reference (PDF) to common Mac keyboard shortcuts is available here: http://davespicks.com/writing/programming/mackeys.pdf
 +
 
 +
You can also change keyboard shortcuts on a Mac:
  
=== Blinking Question Mark ===
+
# Click on the Apple symbol on the menu bar -> System Preferences -> Keyboard
 +
# 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.
  
*Symptom: Your Mac won't start up. You see a white or gray screen with a blinking/flashing question mark.
+
== Languages and international input on 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 ====
+
==== Configuring keyboard inputs ====
  
*Reset the PRAM (http://support.apple.com/kb/HT1379)
+
# Apple menu -> System Preferences -> International
*(if this is a MacBook) Reseat the hard disk (Instructions: http://manuals.info.apple.com/en/MacBook_13inch_HardDrive_DIY.pdf)
+
# 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.
*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 you want, you can also configure the keyboard shortcut to switch between languages. Look in System Preferences -> International.
*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 ====
+
* 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".
If you need to get files from the computer, you can:
 
  
*Try putting the Mac in [[Target Disk Mode]] and connect it to another Mac to copy your files.
+
==== Change the system language ====
**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 ====
+
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.
  
*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 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.
** 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]])
 
** '''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 ====
+
== Taking a screenshot in Mac OSX ==
  
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...

* To take a picture of the entire desktop, press '''APPLE + SHIFT + 3'''.
 +
* 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.

== Troubleshooting Fonts on Macs  ==
  
==== Check disk ====
+
Sometimes, installed fonts do not appear in Font menu. For example the Bembo font has been installed (install instructions here: http://kb.iu.edu/data/aklg.html), however the customer does not see it under the font list in some or all applications.
# Boot into Single User Mode by holding down Apple + S on boot.
 
# When system has loaded, enter <code>fsck -fy</code> to check disk.
 
  
==== Target Disk Mode ====
+
* '''Cause''': There may be duplicate copies of the font.
See [[Target Disk Mode]] for how to use. Boot a Mac using another Mac's hard drive so you can:
+
* '''Solution 1''': Quit all open apps (except the finder), then open: Applications =&gt; Font Book, select the font that has issues, then from the "Edit" menu select "Resolve Duplicates". Keep doing that until the dot next to the font name disappears. When the dot next to the font name has disappeared, quit Font Book and try using the font.
* Access the internal hard drive without depending on it to boot the system
+
* '''Solution 2''': If the above doesn't resolve the issue, try validating all fonts: In Font Book click "Edit" =&gt; "Select All", then click "File" =&gt; "Validate Fonts". If there are any errors or warnings, place a checkmark next to each and click "Remove Selected". You may need to restart the computer to apply the changes.
* Run Disk Utility to repair disk permissions
 
* Run Disk Warrior for advanced repair techniques

Reinstalls system without touching user files (in theory). A messed-up install might be fixed this way.
 
  
== Reinstalling Mac OSX ==

You can check the capacity/free space of your main disk by following these steps:

# Click "Utilities" (the Utilities folder will open)

# Double-click "Activity Monitor"

# In the Activity Monitor window click on the Disk Usage tab on the bottom. Details on the space free and space utilized will be displayed.
  
* 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.
