On the other hand, myself and numerous others have found that Help Center can be unresponsive, crashy, or simply non-functional. Based on my experiences, submitted hints, and reading elsewhere on the net, here are some things to try if you're experiencing a recalcitrant Help Center. Please keep in mind that these are just suggestions and may or may not solve your particular problem.
- If you open Help Center by itself in the Finder (Help -> Mac Help) and notice you have an empty entry in the drawer at the right listing the available help topics, try this. Look in /Library/Documentation/Help for a Virex7.help file and remove it (or possibly just remove the extension). This tip first appeared on the Macintouch Reader Reports, submitted by Dave Gomme.
- When I experienced the spinning Aqua blob when launching Help Center, I went to ~/Library/Preferences and trashed anything with "apple" and "help" in its name. The next time I launched Help Center, it worked perfectly (and has ever since, amazingly enough).
- An anonymous tipster suggests deleting the folders ~/Library/Documentation/Help and ~/Library/Caches/com.apple.helpui (the entire folders) to force Help Center not to read from these cached files. I have no idea of the functionality of these folders, so use this one at your own risk.
