Mac Help viewer is blank

I've been using Tiger on this G4 for several months. Today, I clicked on Help menu in the Finder window. The viewer came up, but it was blank.
At the same time, something happened to my Airport, but I got connected through Diagnostics.
How can I get my Mac Help working?

  • Help with Mac Help Viewer

    Hello to whoever is looking at this posting. This may be somewhat out of the norm, but for some odd reason, if I ever try to use the Help function in finder, nothing displays. I just get a blank screen with the "ask a question column", but it acts like it is trying to load continuously. I have to force quit to exit.
    Does anyone know why this would be or if there is a specific software update to rectify this problem. This machine is still under 1 year basic warrenty, would it make sense to contact support for this? I have no other software conflicts which is the weird thing. Im using Mac OSX Version 10.3.9.
    Thank you for any help with this help issue!

    Help Viewer crashes or shows blank....
    http://discussions.info.apple.com/webx?[email protected]@.6897a2ae http://www.thexlab.com/faqs/helpviewer.html
    This is a common bug in Panther. The solution to this problem is simple though:
    • (~ means your home directory)
    Go to ~/Library/Preferences and delete the following files.....
    com.apple.help.plist
    com.apple.helpui.plist (you may or may not have this one).
    com.apple.helpviewer.plist
    Next go to ~/Library/Caches and delete the folder......
    com.apple.helpui
    Log out and log in. If the problem is gone, empty the trash. If not, put everything back.
    or you can open MacHelp directly from .....
    /Library/Documentation/Help and it works fine.

  • Is there any hope for Help Viewer?

    I have read through as many discussions about Help Viewer problems as I can find, and still, help in Finder doesn't work. I have tried all of Dr. Smoke's suggestions and many others to no avail. Help Viewer still ends up going back to a blank screen, links that don't work, and the search just keeps searching.
    All of the suggestions I have tried fix Help Viewer temporarily, but it has always gone back to its same old broken self.
    If anyone out there can REALLY help, I would REALLY appreciate it.
    Thank you!

    Hi Jordan. Hopefully I can offer a solution for this which bugged me enough to really try to resolve it, and have now done so, at least for me.
    First the essentials.
    System Setup: Powermac G4 Dual 1GHz MDD. 1GB. MacOS 10.4.3
    Issue: Loading Mac Helper from the Finder will result in a blank screen after the first launch. On first launch you will be able to click one or two links then it will not work and search will not function [issues may vary but blank screen always]
    This problem occurred with earlier versions of Tiger. I have since done a clean install. Tried replacing the Help Viewer app from the Install disk and also the MacHelp.help document too, but it did not help. I even tried the same items from other disks just to check for corrupt files but still no change. Trashing the prefs does not seem to make any difference, nor the same with the cache folder but it can resolve other issues, just not this particular one.
    NOTE Before others try this fix I strongly suggest you try the solutions suggested by Apple and those on the very good XLab web site. Here are a few related articles:
    XLab. The most comprehensive guide to the Help issues.Check out the 'Help Viewer displays a blank window.' link.
    http://www.thexlab.com/faqs/helpviewer.html
    Apple. From the source. Not quite the same symptoms but offers Help advice on
    'Mac OS X 10.2, 10.3: Mac Help Viewer unexpectedly quits'
    http://docs.info.apple.com/article.html?artnum=107013
    Solution:
    1. Go to User > Library > Caches > com.apple.helpui [note: you need to launch Help Viewer at least once so that this folder is created]
    2. Delete ALL files/ folders in the com.apple.helpui folder, if any.
    3. Create a new folder inside com.apple.helpui and name it 'Mac Help' [the same as that created automatically by Help Viewer, case sensitive].
    4. Select the new folder and use Command + I to see the folder 'Info'. First
    label it red [to aid further diagnostics] and then change ALL the permissions at the bottom to *Read only* [click Details to see the options, not just 'You can'. Include Read only for 'Owner', 'Group' & 'Others'. You will need Admin access for this]. Close the Info panel.
    5. Launch Mac Help from the Finder menu bar. If it was blank before, the Help Viewer screen should show the Mac Help homepage again. Try several links and search and Index. They should all work, and quicker now. Quit and relaunch. This time the Help Viewer works now and no blank screen. The issue with Mac Help is fixed ( but be aware that any other Help folders created could well cause the same issue, so check for these if it still happens and read on for details of how to deal with this other part of the issue)
    *BUT*
    Although this resolves the Mac Help issue, AS SOON AS OTHER MAC APPLICATION HELP's ARE LAUNCHED, IT IS MOST LIKELY THE ISSUE WILL RETURN!, hence the labeling of the Help folders red, to track newly created Help folders (i.e. Mail Help, Safari Help etc). If these are launched this automatically creates help folders in com.apple.helpui for them and they also cause the blank screen problem.
    So, the best thing is to create Help folders in the same way that you did for Mac Help, for ALL Mac applications to avoid having to do it incrementally as and when you use another Mac application Help [or if you do a search it may well create folders anyhow]. These are the Help folders I have created, with the red label and 'Read only' permissions:
    Activity Monitor Help
    Address Book Help
    AirPort Help
    AppleScript Help
    Automator Help
    Bluetooth Help
    Calculator Help
    Chess Help
    Console Help
    Dictionary Help
    Directory Access Help
    Disk Utility Help
    DVD Player Help
    Font Book Help
    Grapher Help
    iCal Help
    iChat Help
    Image Capture Help
    Mac Help
    Mail Help
    ODBC Administrator Help
    Preview Help
    QuickTime Player Help
    Safari Help
    Script Editor Help
    Sherlock Help
    Stickies Help
    System Profiler Help
    Terminal Help
    TextEdit Help
    There are probably more but these are the ones I could find fairly easily. If they are labeled red then it is easy to see if any others appear and cause the issue. Once I have done this I make a backup copy of these folders with the permissions set and archive it for use as and when I need to replace them.
    Result: For me and my setup this has resulted in my being able to use Help normally without the blank screen issue for nearly two weeks now since I spent a lot of time looking at this issue. In fact I find Help works a lot faster and suffers fewer delays. Because this only requires amendments to file permissions, in a folder which is automatically replaced if deleted anyhow, I feel it is a safe and easy enough for most users to do if they have this problem.
    I hope this offers a solution to other users with the same issue and who have tried the other suggestions (Including Dr. Smoke's and from Apple etc) but still have problems with the blank screen.
    The Cause & Other Notes
    Having been frustrated with this issue for several months now I spent some time trying to find the cause. It clearly does not effect everyone, and others have found the suggested fixes, such as trashing the com.apple.helpui cache folder and relevant preference files, have worked for them. It makes it a more complicated problem to identify. It appears perhaps to be related to your type/ speed of connection from the computer to the Apple help servers where the cache folders and files and downloaded from. This seems likely from error messages. It also appears that, for whatever reason, some of those files being automatically created when Help Viewer is launched are the actual problem. In order to explain why I think that, if you have this issue then you should get the exact same repeatable test which led me to find the solution.
    Do this:
    1. Firstly navigate to > Library > Caches > com.apple.helpui and trash this folder. Then before proceeding launch the following apps to help diagnose and follow what is happening:
    a. Console [so you can watch for error message in console.log window]
    b. Activity Monitor [to watch internet traffic during launch and browsing the Help Viewer]
    c. Leave the FInder window so you can watch what happens.
    2. Launch Mac Help from the Finder menu bar. It should launch and show the home page on the screen. Immediately you will see a new com.apple.helpui folder being created. Navigate into this so you can watch what is being placed in the newly created com.apple.helpui folder.
    3. Now click on any of the Help links on the right (not the link to the apple web site). Immediately (slower if dialup and not already connected) you should see traffic over the network as the computer connects to the Apple help servers. Then, in the com.apple.helpui folder you will see a new folder called 'Mac Help'. Also some other numbered (0-15) cache folders which are not of interest right now. And on quit a file called 'TOCCache.plist' which does not effect things. Soon you should see an error in the Console console.log window something like this:
    "2005-11-19 01:57:45.585 Help Viewer[1313] Exception raised during posting of notification. Ignored. exception: * End of archive encountered prematurely at 400"
    I am not sure exactly why this is but it appears to be related to some sort of timeout and failure to fully download some items.
    4. Now try to click on any link or Index. For me, nothing happens and I get only more error messages like:
    "2005-11-19 02:02:21.190 Help Viewer[1313] Uncaught exception - * End of archive encountered prematurely at 400
    2005-11-19 02:02:21.190 Help Viewer[1313] * Attempt to remove unrecognized exception handler 0xbfffdce0"
    The only option is to quit out.
    5. Immediately relaunch Mac Help. If it is like me then it will now be a blank screen accompanied by the following my critical error message:
    "2005-11-19 02:03:33.543 Help Viewer[1319] * NSRunLoop ignoring exception '* End of archive encountered prematurely at 400' that raised during posting of delayed perform with target 375df0 and selector '_setupTOC'"
    Now, everytime I quit a launch Mac Help it is the same error and blank screen.
    This seemed to me to point towards an issue within the com.apple.helpui folder because when it is trashed Help Viewer will launch one time then stop.
    So I went through each folder (I had a number of Help folders the first time) and tried moving it out of the folder, rather like testing for bad prefs in OS8.
    Eventually I tracked the offending file/s down to this:
    User > Library > Caches > com.apple.helpui > Mac Help > Contents > Resources > English.lproj > pgs > pgs.helpindex
    As soon as this file is created then it all stops. Trash this file and relaunch and the homepage appears again until it appears and once again the problem reappears. This is totally repeatable for me.
    Once I had isolated the problem file I tried various solutions to resolve it. The first was to replace it with the same file which is already in the System within the MacHelp.help documentation here (the system Library, not the User path)
    Library > Documentation > Help > MacHelp.help
    Copy MacHelp.help and then use Command + I and 'Show Package Contents' to navigate to:
    MacHelp.help > Contents > Resources > English.lproj > pgs > pgs.helpindex
    (right at the bottom of the pgs folder with hundreds of .html files)
    I then replaced the existing pgs.helpindex with this one. It is different at it has an earlier Created date of 16/03/2005 (my vary), the one in the cache folder is Created 20/10/2005 (may vary?)
    This allowed Help Viewer to launch correctly, but after a short time and re-launch it returned to the blank screen. Examining the file showed it was being overwritten by the later downloaded version, the one causing the problem. This led me to change the permissions to 'Read only' to prevent it being overwritten and after this the Help Viewer worked normally on relaunches.
    I also changed and altered the permissions on the pgs/pgs2.helpindex folder in the same directory as the pgs folder as it seemed to also cause a problem.
    So, finally I resolved the problem, with no error messages, the Help Viewer loading correctly and a working Help. However, I noticed that after a while the blank screen came back. Knowing the pgs.helpindex was OK it seemed likely that other .helpindex files in other Help folders created in the com.apple.helpui folder. This proved the case because, on trashing the new Help folder, it launched again. Swapping the downloaded .helpindex in say, Mail Help, and changing the permissions fixed it, until another Apple application Help folder was created and it re-occurred. The problem does not occur with all the Mac application Helps, but with some (notably for me, Mail Help, Safari Help and some others).
    Finally I found that rather than digging into the apps contents I could get the same fix and also quicker Help browsing by simply creating the actual Help folders as described above and ensuring the .helpindex (or other folders/ files like idx) was not created.
    From nearly two weeks trials it so far appears to completely resolve this issue.
    Just be aware of any new Help folders/ files being created.
    The are a few other observations:
    1. I tried just altering the permissions on the actual com.apple.helpui folder to 'Read only' but whilst it allowed the Help Viewer to open fine, it broke links within the application Help windows.
    2. I have not tried many Helps on other non Apple applications. I find that Toast help triggers error messages:
    "2005-11-19 02:27:02.229 Help Viewer[1340] -[IdxSearchController openIndices:] caught a VTWIN exception. Bad index file is /Applications/Toast 7 Titanium/Toast Titanium.app/Contents/Resources/English.lproj/Toast Help/Toast Help idx
    It is not possible to change the 'Toast Help idx' as it is an exec file. The errors do not seem to break Help Viewer. I had similar error messages from Quicktime Help when it loaded. I suspect that the Toast help is broken for similar reasons as mac Help b (it works for links to installed pages but not external ones). But it could be from the alterations to the Help folders. Either way at least Help works.
    3. It is possible to get most .helpindex files from the relevant application contents but just using the Help folders is a quicker solution.
    4. I can't help feel that the difference between those that have or do not have these issues is a slower connection, i.e. non-broadband. I have a 64k ISDN connection through a router which is pretty much 'always on' with solid 7KB speeds, but it seems this is insufficient for Help to work properly. I read elsewhere that connection speed appears to be an issue and Help is sensitive to this. It would be interesting to know what type of connection people with the issue have. I also have a hardware firewall in the router which may be a factor but it does not stop any other normal traffic and allows the files through anyhow. It has been in place for 6 years and with no issues. Just wanted to note it.
    5. Certainly for my situation, it appears that the files being downloaded from the Apple help servers are actually causing the problem at my end. I can't explain why or how other than the tests explained above are repeatable and that using the same file but from the System file resolves the problem. It remains unclear why a slower connection would lead to files downloading which affect some people but not others? It may be something totally different of course but the error messages in Console do seem to point towards this.
    6. I imagine the reason why the files and folders are downloaded are to ensure that they are kept up to date, as the pgs.helpindex for instance is a later creation date. However I do not seem to have any problems browsing or looking at topics, especially with the 'Include product Support Searches' option selected in the Help View menu. It means that there is extra traffic but gives a wider range of responses from Apple. Perhaps it is better to deselect this option if you have a slow dialup connection?
    Summary
    I hope that this solution can help others with this issue and perhaps other related problems. There is no way of me testing it further and I do not know how others who seemingly do not have a problem can check this. I just know it resolved it for me. I am no expert but a long time Mac user who is used to simple and elegant functionality, not the ongoing saga of the current Help, and wanted the thing just to 'work'.
    Good luck

  • Finder, Mac Help

    Has anyone had problems using the Mac Help on the iBook G4. Whenever i open it I just get a blank window. If I click the home button, it goes to the home window but none of the links work. This has been happening since the August security update

    Hi Johnman,
    See if this short answer helps:
    Try first (quit Help) deleting this folder:
    Home/Library/Caches/com.apple.helpui
    If Help still doesn't work, try then deleting those files:
    Home/Library/Preferences/com.apple.helpviewer.plist
    Home/Library/Preferences/com.apple.help.plist

    - Mac OS X 10.2, 10.3: Mac Help Viewer unexpectedly quits
    or this X-Lab FAQ
    - Troubleshooting Help Viewer.
    Of course, being online or not shouldn't matter. Unfortunately Mac Help has always been very sensitive because it searches online.
    I think interrupting a search, for example, is enough to corrupt its caches or .plist files...
    Sending Feedback?
    Good luck!

  • 10.4.4 Mac Help does not work

    I just upgraded 10.4.3 to 10.4.4. Now Tiger Mac help does not work. Other software help does work, at least those I have checked like Word, Safari, and a few others I have checked. But in the Finder going to help in the Menu bar does brings up the help window, but try to click a link like What's new in Tiger or typing a query into the search window produces nothing. All the software seems to be working fine, at least what I have checked. I have redownloaded and re-installed making sure virus software is off to no avail.
    Any help would be appreciated.

    I tried the steps mentioned before, and thought I would give them one more try. Initially, I had success in that the Help Viewer opened to the default Mac Help view, and when I typed in a find term, lo & behold a list of results appeared! Alas, my visions of success vanished when I clicked on one of the results, then View.....nothing happened!
    I returned to the main menu, and found none of the links would work, and neither would the search function!
    It appears a link may work the first time, but none after that.
    I also noticed that (repeating the Cache & Preference removal steps) that they repopulated with the files when Mac Help was initiated, and, as before, would allow one link acivation to occur, but none after.
    I suspect there may be a conflict with some other applications Help feature, but made sure to activate ONLY the Mac Help with no other Application having been run after restart. The only other possiblity is that some toolbar non-Mac OS X help apps like Magic Menu, Quicken, & iPod conflict, but these are all I have!
    If any one having this Help Viewer problem has similar installations, or knows of any conflicts with these; or, how I can temporarily disable/remove the associated help without uninstalling them, please post a reply.

  • Problems with "Mac Help"

    My help files, especially "Mac Help", no longer work properly since upgrading to Tiger. If I open "Mac Help", for example, the help window will pop up, but the links will not work (nothing happens when I click on them) and the search feature in help will not work either (the little gray "clock" just spins next to the help bar and nothing else ever happens). Any suggestions on this one? As I'm a relatively recent Mac convert, the help feature was something that I came to rely on. Thanks!

    Hi CP,
    This is a common problem with Mac Help. When it happens, try first (quit Help) deleting this folder:

    If Help still doesn't work, try then deleting those files:
    Home/Library/Preferences/com.apple.helpviewer.plist
    Home/Library/Preferences/com.apple.help.plist
    (and this one if you find it):

  • Mac Help in Finder comes up blank

    Whenever I go into the Finder and choose Help, the Help window comes up totally blank. If I enter a question, the results show nothing.
    I only have this problem on my G4 PowerBook, so I usually use my tower, but when I am not home it is a pain.
    Is there a way just to reinstall the Help files?
    Thanks!

    I have exactly the same problem but I haven't looked into it as I will be returning this 12" baby to Apple soon due to other issues.
    My previous 12" pBook (also returned for quality issues, natch) had, as I recall, a working Apple Help function in finder until I partitioned the drive and re-installed Tiger. Thereafter, no Apple Help. I tried copying Help files and Help App across from a working PB system but to no avail.
    The current one has been upgraded to 10.4.4 and I still have nothing in the Apple help.
    Alas the workaround above does not help either. If you access help from another App, then hit the Home button to get the Apple Help home page, none of the topic links is active.
    I have been meaning to post on this for a while and am amazed to just come across it for the first time.... wait a minute.
    ... OK BREAKING NEWS! (sorry to shout).
    I have just done a search in discussions for Help Viewer and it seems this is a known issue. There is a simple solution. Just tried it - and it works... Woo hoo!
    Follow the instructions here
    Okay, there is a lesson here: always search Discussions in case our problem as already been solved!

  • Mac Help feature blank box

    The Mac Help function often comes up totally blank, or if it has hyperlinks, they do not work.
    This happens at anytime, seemingly unrelated to anything else.
    What to do?
    Thank you for your consideration.

    Hi Francis,
    (in addition to R C-R's excellent answer)
    Yes, you can rename the corrupted caches folder, or simply get rid of it by dragging it to the Trash.
    If deleting the Home/Library/Caches/com.apple.helpui folder still doesn't fix Mac Help,
    try then deleting those preference files:
    Home/Library/Preferences/com.apple.helpviewer.plist
    and
    Home/Library/Preferences/com.apple.help.plist
    A common and harmless problem, most probably related to Mac Help's hyper-sensitivity to erratic internet connection while updating its contents.

    This is a common bug in Panther. The solution to this problem is simple though:
    • (~ means your home directory)
    If the search field is not in the top of the window.... click on the oblong button at the top right hand corner...that should open the Toolbar and display the search field.
    Go to ~/Library/Preferences and delete the following files......

    com.apple.helpviewer.plist
    Next go to ~/Library/Caches and delete the folder......

  • Mac Help failed again

    The Mac Help system on my computer fails often. Before, I have been told to drag help cache files to trash and shut down and restart. The help cache files appear to be gone. If I ask for help I get a blank screen. Do others have this problem? why is this so vulnerable. Help should be one of the most reliable parts of an Operating System .

    Hi, brooktrout.
    See my "Troubleshooting Help Viewer" FAQ for comprehensive advice on fixing issues with Help Viewer, including the issue you mention.
    As FYI, you should update to a more recent version of Mac OS X than 10.4.5 — the version shown in your profile. The version of Help Viewer in later releases seems to have solved some long-standing problems.
    Good luck!

  • How can I get Mac Help to work?

    Every time I open a folder, a big question mark appears at the top - how can I correct this?
    It seems that Mac Help isn't working. After opening it, the same question mark shows in the dock's Help Viewer and when the help viewer opens, it is blank.
    Thank you for any help!

    Try the following:
    In most cases doing the following will restore the Help Viewer:
    1. Trash the following three files, if extant:
    /Home/Library/Preferences/com.apple.help.plist
    /Home/Library/Preferences/com.apple.helpui.plist
    /Home/Library/Preferences/com.apple.helpviewer.plist
    2. Trash the /Home/Library/Caches/com.apple.helpui folder.
    3. Empty the Trash and Restart.
