System Requirements: Mac OS X 10.5 or 10.6 (sorry, it doesn't work on Mac OS X 10.4 and below).

Version 2.8 of this Applecript application is available in the large "tools" archive linked to at the end of the main blog.

Instructions for Use

1. Download the latest tools zip archive, unzip it by double-clicking, and open the DeDRM_for_Mac_and_Win folder.

2. Unzip DeDRM_X.X.app.zip by double-clicking it.

3. Place the AppleScript application in your Applications folder or on your Desktop, or wherever is convenient for you.

4. Run the AppleScript application by double-clicking it.

5. You can remove the DRM from a single ebook file by clicking on the "Select Ebook…" button.

Alternatively, if you need to remove the DRM from ebooks that aren't from Kindle for Mac or Adobe Digital Editions, click on the "Configure…" button to enter the keys needed for the various ebook formats. And, if you want all your drm-freed ebooks to be saved into a particular folder, instead of into the same folder as the original ebook, choose that folder at the end of the Configuration process.

6. To remove DRM from several ebooks or folders of ebooks at once, just Drag & Drop the files and folders onto the AppleScript application when it is not running. Having a link to DeDRM in your dock makes this convenient.

Amazon Topaz ebooks: Most Amazon Kindle ebooks are Mobipocket format ebooks. However, some are in a format known as Topaz. This AppleScript will remove drm from kindle ebooks, but to allow the file to be converted into other formats, the Topaz format must be converted during the de-drming process. The end result is that you end up with three files from one Topaz format ebook. Windows user, please refer to kindle drm removal.
