iDefrag keeps asking me to drop my license key when I start it

(The rest of this article assumes you have purchased the version of iDefrag you are trying to use. If not, you can purchase from the iDefrag page.)

Some customers have reported that iDefrag is asking them to drag and drop their license key every time they run the program. We have tried — and failed — to reproduce this problem, but what we do know is that manually removing the existing license data from your system appears to fix it.

There are two ways to do this, as follows.

From Finder

  1. Choose “Go to Folder…” from the “Go” menu. Please do not try to skip this step by browsing for the location yourself — there are multiple “Library” folders and you will very likely pick the wrong one.

  2. Enter

    /Library/Application Support/iDefrag

    Note that this is not the folder in your home folder.

  3. Press “Go”.

  4. Delete the file “iDefrag-5.dat”.

From Terminal

  1. Enter

    sudo rm "/Library/Application Support/iDefrag/iDefrag-5.dat"
  2. When prompted, enter your password (the one you use to log-in to your computer). Note that you won’t see your password appear on the screen; this is normal, and is to stop people looking over your shoulder from seeing your password.

When you’ve finished, the Terminal window should look something like this:

Last login: Tue Apr 28 14:06:48 on ttys001
My Mac$ sudo rm "/Library/Application Support/iDefrag/iDefrag-5.dat"
My Mac$

If it displays any error messages, let us know and we can explain what they mean.
