How to Eliminate iWork ’09 Serial Number Prompt


Apple customers using iWork ‘09, have reported that, in some rare cases, the serial number prompt won’t go away, even after installing the full version of the software.

The company informs that, although installing the full version of iWork should allow customers to start using Pages, Keynote and Numbers without problems, in some cases the installation process may be blocked by a dialog asking the user to input their serial number.

This may happen if a trial version of iWork ’09 is already installed and it is a higher version number than the one being installed from DVD.

The resolution is fairly simple. Basically users need to delete a couple of files. However, not everyone will know where to locate them.

The proper procedure, as outlined by Apple themselves, is:

1. In the Finder, click the Go menu and choose Applications.
2. Locate the “iWork ’09″ folder and drag it to the Trash.
3. Click the Go menu once again and and choose Go to Folder.
4. In the prompt, type:  /Library
5. Click the Go button.
6. Open the Application Support folder.
7. Locate the “iWork ’09″ folder and drag it to the Trash.
8. Return to /Library using the back arrow in the Finder window.
9. Open the Preferences folder.
10. Locate the files “” and “” and drag these to the trash.
11. Reinstall iWork from your Installation DVD.


“Following” hashtags on TwitterDeck


Hashtags are a powerful tool that allow you to track what people are tweeting about a particular topic.  Although hashtags aren’t a service that Twitter officially supports there are a lot of third party apps that support following them.  My favorite is TweetDeck.  TweetDeck allows you to create columns that allow you to merge multiple Twitter accounts, tweets that mention your username or hashtags of your choice.

Adding a column is fairly straight forward.  First click on the add column button on the top left corner of TweetDeck.

In the field that opens up type in the topic that you want to track.  Be sure to add the # in front of the topic so TweetDeck knows it’s a hashtag.   For example, if I wanted to search for all tweets in EdTech, I would type:  #EdTech.


Splitting iTunes library over multiple hard drives


With the price of storage so low I have the luxury of owning a custom PC that I put together myself.  8GB of RAM, 5 Terabytes of storage and yes, it also washes my dishes.

I’m slightly anal when ti comes to separating my media so I wanted a way I could put my movies on one hard drive, my music on another and my television shows on a third.   My main operating system and program files reside on a separate hard drive as well.   The dilemma being I am slightly wedded to iTunes as a management tool since most of my television shows were bought through the iTunes store.

iTunes not so conveniently stores all of your files under one folder (in sub-folders, of course).

But there is a solution!

1.  Find all of your existing iTunes movies and TV shows and move them to your new drive using Finder (or just drag and drop them in Windows). The movies are normally located at/Users/[Your_Username]/Music/iTunes/iTunes Music/Movies and the TV shows are at/Users/[Your_Username]/Music/iTunes/iTunes Music/TV Shows.

Newer versions use a iTunes Media folder.

2.  Once these two folders and their contents have been copied to your new drive, launch the iTunes software.

3.  Using the left sidebar, go to the Movies heading. Select all of the items there, right-click, and choose Delete from the menu. First you’ll be asked for confirmation that you want to remove the movies from your library (you do), and then you’ll be asked whether you want to keep the file itself or move it to the trash. Select Move to Trash.

4.  Repeat step 3, this time using the TV Shows heading instead of Movies. You’ve already copied the files to another hard drive so don’t worry about losing them.

5.  Now it’s time to re-add the video files back into your library. Open your new drive and locate the Movies and TV Shows folders you copied at the beginning.

6.  While holding down the Option (Shift on Windows) key, drag the Movies and TV Shows folders from the Finder window to iTunes. Everything should go right back to the way it was with one exception — the video files are now stored on a different disk volume rather than on your Mac. The Option key keeps them there by overriding the iTunes setting which automatically copies files back to the internal disk.

7.  Any time you want to add a new movie or TV show to your library, move it over to the appropriate folder on your new hard drive, hold Option, and drag it to iTunes.


Adding multiple episode dvds to Boxee


I love Boxee.  I have a vast collection of dvds that I ripped to iso’s and just recently began ripping my television series collection (Highlander, Twin Peaks, Buffy, Fringe, etc).  My biggest frustration in this process is that Boxee doesn’t provide an easy way (yet) for multiple episodes to be recognized from one dvd.

The answer is symbolic links. If you create a symbolic link for each season and point it to the iso file that contains that episode Boxee recognizes the episodes and adds them to your database.
The format is as follows:

ln -s path_to_iso name_of_episode

ln -s /tvshows/”24 Season 1 Disc 1.iso” “24.S01.E01.iso”
ln -s /tvshows/”24 Season 1 Disc 1.iso” “24.S01.E02.iso”
ln -s /tvshows/”24 Season 1 Disc 1.iso” “24.S01.E03.iso”
ln -s /tvshows/”24 Season 1 Disc 1.iso” “24.S01.E04.iso”

Obviously, you do this from command line.  If you don’t want to mess with pathways, just navigate to the folder where you keep your iso’s and have at it!    Hope this helps.
