Troubleshooting Help Viewer This FAQ, originally derived from our book, provides solutions for common problems with Help Viewer in:. Mac OS X 10.6 Snow Leopard®. Mac OS X 10.5 Leopard®. Mac OS X 10.4 Tiger®. Mac OS X 10.3 Panther®. Mac OS X 10.2 Jaguar. This FAQ is divided into three primary sections:.
This section provides some general information about the operation of Help Viewer that is useful in troubleshooting. This section provides specific techniques that are employed in both troubleshooting of Help Viewer and resolving some of the common problems with such. The techniques covered in this section are:. This section provides steps for resolving the following common problems with Help Viewer:. About Help Viewer The following facts about Help Viewer are useful in understanding its operation for troubleshooting purposes:. Help Viewer is essentially a basic Web browser.
In Panther and later releases of Mac OS X, it is based on Web Kit, the same Mac OS X technology employed in Safari. The help information displayed in Help Viewer is distributed in help books. Help books are written in a subset of the same standards employed in creating Web pages: HTML (HyperText Markup Language) and CSS (Cascading Style Sheets). This is described in the Apple Developer Connection document. A help book generally contains all of the text and images for a given set of help information. It also includes the searchable index employed when you search for information in Help Viewer.
If you are using Tiger, note that the searchable index for a help book is unrelated to the Spotlight index of your startup disk. The searchable index is created by the author of the help book as part of the help-book authoring process.
Some help books have Help Viewer check the Internet for updated content, which is downloaded and displayed in lieu of the information in the help book if the Internet-based content is more recent. Help books can also be designed so that some or all of their help information is only available via the Internet. Help books are installed in one of two ways:. Directly in the Macintosh HD Library Documentation Help folder. Distributed as part of an application's package file and contained within the package of the application for which the help book provides help information. Help books have the extension.help. For example, the file MacHelp.help in the Macintosh HD Library Documentation Help folder.
Under Mac OS X 10.5 and later:. The Help Viewer window floats above all other windows in its own layer. Opening an application's Help still opens Help Viewer, but Help Viewer no longer appears in the Dock or the Application Switcher (Command-Tab). Help Viewer has no a menu bar. Most keyboard shortcuts do not work in Help Viewer.
The exception is Command-F (Find) under Snow Leopard for locating text within a help document. An unintended consequence of this is that keyboard shortcuts performed in Help Viewer are executed in the application that had focus before help was opened or before the Help Viewer window was selected.
For example, pressing the Command-Q (Quit) keyboard shortcut does not quit Help Viewer but the application that had focus before the Help Viewer window was selected. More information about Help Viewer in Leopard can be found in the 'Help Viewer' chapter of our book. Help Viewer troubleshooting techniques The following troubleshooting techniques are applied in resolving a variety of common problems with Help Viewer.
Applying these techniques in the order specified can also form the basis of an approach to troubleshooting Help Viewer should none of the common problems with Help Viewer exactly match the specific issue you are attempting to resolve. The techniques covered in this section include:. Reset Help Viewer Most Help Viewer problems are the result of corrupted Help Viewer cache or preferences files. The following steps will resolve such problems.
Note that these instructions cover multiple versions of Mac OS X: you may have only some of the files or folders cited for deletion. Close or quit Help Viewer if it is open:. Users of Mac OS X 10.5 or later should click the red Close button in the upper-left corner of the Help Viewer window. Users of Mac OS X 10.4 and earlier can press the Command-Q (Quit) keyboard shortcut. Trash the following files in your Home Library Preferences folder, if extant:. com.apple.help.plist. com.apple.helpui.plist.
com.apple.helpviewer.plist. Trash the following folders in your Home Library Caches folder, if extant:. com.apple.helpui folder. com.apple.helpdata. com.apple.helpd. com.apple.helpviewer.
Empty the Trash. Under Snow Leopard, if you receive an alert stating that the Trash cannot be emptied 'because the item Cache.db is in use,' then:.
The helpd (help ) is a new process under Snow Leopard that provides various services to Help Viewer. Empty the Trash. Test that Help Viewer is now operating normally. If not:. Leopard users: Delete the hidden Help Viewer cache folder.
For instructions, see the 'Help Viewer' chapter of our book. Tiger users: Check your account's for iTunes Helper. If you find iTunes Helper in your account's Login Items:. Select iTunes Helper in the list of Login Items.
Click - to remove iTunes Helper from the list of Login Items. Restart your Mac. These additional steps are recommended under Tiger as iTunes Helper can cause the problem to recur the second time you launch Help Viewer after performing steps 1-5. When you next open Help Viewer, you may notice that the Library menu lists Help for only a few applications.
This is not a problem. When you next request an application's Help, it will again be listed in the Library menu or Help Center.
Rule out broken help book aliases Broken aliases to help books can cause a number of Help Viewer problems. Depending on the version of Mac OS X, they may result in 'Connection failed' alerts appearing when opening Help Viewer or attempting to open an application's help. There are two common reasons for broken help book aliases. First, the alias points to a help book that has been deleted; this can occur if the associated software was uninstalled, but the alias to its help book was not removed. Second, the alias points to a help book on another computer on the network and one of the following three conditions is true: the original help book has been deleted from the other computer, the original help book is corrupt, or the other computer is disconnected from the network. Aliases to help books may be found in one or both of the following two folders:. Macintosh HD Library Documentation Help folder.
A user's Home Library Documentation Help folder. Complete instructions for troubleshooting broken help book aliases can be found in the 'Help Viewer' chapter of our book. Rule out Internet-related issues If Help Viewer works properly when your Mac is disconnected from the Internet, but fails either intermittently or consistently when your Mac is connected to the Internet, Internet-related issues may be the cause.
If you are having problems surfing the Web in addition to using Help Viewer, this is another clue that your Help Viewer problems may be caused by Internet-related issues. Proceed as follows:.
Rule out incompatible Internet plug-ins. If you have installed third-party Internet plug-ins, disable or uninstall these to assure they are not interfering with your Internet connection. In particular, certain download accelerators applications that claim to enable faster downloads through your Web browser have been shown to interfere with Help Viewer.

Third-party download accelerators are often implemented using an Internet plug-in. Internet plug-ins can be found in the following two folders:. Macintosh HD Library Internet Plug-Ins folder. Your Home Library Internet Plug-Ins folder.

Third-party Safari add-ons particularly applications that add new features to Safari or provide services such as ad blocking may install modifications to Web Kit that could affect Help Viewer. Rule out third-party Safari add-ons you have installed by either checking for updates, disabling them, or uninstalling them. While we have no specific evidence to suggest a given Safari add-on may interfere with Help Viewer, it is something to consider given that both Safari and Help Viewer employ Web Kit.
